This cozy bowl of Brown Butter Brussels Sprout and Bacon Fettuccine Alfredo is THE best any night of the week fall pasta. I’m taking a classic pasta recipe and updating it with a rich and creamy sauce, crispy Brussels sprouts, and bacon. Every twirl of pasta has delicious fall flavors that melt in your mouth. It’s the coziest, creamiest bowl of Fettuccine Alfredo that’s fancy enough for the weekend, but easy enough to make any night of the week. And most importantly, it’s delicious.

Growing up, Friday and Saturday nights were always reserved for pasta or pizza dinners. Most Friday nights my dad would make his Friday night pasta dish, which to this day is one of my favorite dishes. It could be due to the fact that it’s my dad’s recipe, but regardless it’s a delicious pasta dinner that I really love.

When dad wasn’t making his pasta dish on Friday night, he was making his Fettuccine Alfredo pasta. A dish both my mom and I always loved. Since he didn’t make fettuccine as often as his other dinners (i.e chicken, rice, and tacos…and then more chicken and rice), fettuccine nights always felt special. Especially in the fall when we’d cozy up by the fire while eating.

Twas’ the best, and I love these memories!

Sidenote, as my mom reads this she’ll also think back to those days. I can already see the smile on her face, we miss those cozy nights by the wood-burning fire.

Here’s the thing, my dad is a great cook, and I believe I take after him when it comes to anything in the kitchen, but the thing about dad’s recipes?

They’re simple as can be, meaning there is no recipe. The way my dad cooks is simple, he takes what he has in the fridge and makes dinner out of it. He doesn’t cook from cookbooks or google anything. He just cooks to eat and hopes it all turns out ok. Thankfully for us, it always did.

The point here is that my dad just winged it in the kitchen, which I swear always creates the very best recipes. My inspiration for this fettuccine was very much my dad (I even used his “secret” ingredient, that’s not traditional), but with my twist, crispy brussels sprouts, and bacon too.

I like to think of this as the fall edition of Fettuccine Alfredo. It’s rich, creamy, swirled with browned butter, and topped with brussels sprouts that taste almost chip-like, plus crispy salty bacon too.

It’s indulgent…but so delicious.

Finally, the details…those sprouts!

Start with pasta. Use classic fettuccine for this. Yes, any cut of pasta will work and be delicious, but Fettuccine Alfredo isn’t Fettuccine Alfredo without the right cut of pasta. So use the fettuccine.

While that pasta water is coming to a boil, start and finish the recipe. Yes, this is a one-skillet, one-pot, thirty-minute dinner.

Cook up your bacon until it’s extra crispy. Now do the same with the Brussels sprouts. You want to get them extra crisp, so cook the sprouts cut side down and avoid stirring for the first four or so minutes of cooking. Once the cut side of the sprouts are crisp, toss and cook until the outside is crispy too, then remove from the skillet. This will ensure they stay crispy, instead of just fading away into the buttery creamy sauce.

Onto the cream sauce. Browned butter, garlic, herbs, a splash of milk, and lots of Parmesan, plus dad’s secret ingredient…the tiniest amount of cream cheese.

This is easy, brown the butter, add the garlic and herbs, then add a splash of milk. I usually just use whole goat’s milk with a light splash of cream or canned coconut milk. If you want to make this a little lighter, simply use all milk or all canned coconut milk. Or if you want to make this less heavy on the dairy, use all canned coconut milk. Promise you don’t taste the coconut at all.

Once you add the milk, whisk in the cream cheese. Now, I know this isn’t typical in fettuccine, but my dad used to make fettuccine as follows: one whole stick of butter, a couple cups of whole milk or cream, and then one eight-ounce package of cream cheese. He’d toss in the pasta, then add more Parmesan than you’d ever think could be added (he loves parmesan). Of course, it was delicious!

It was a heavy sauce, but it was so good, and I think the cream cheese was the reason. It creates a silky smooth sauce every time. I’m only using the tiniest amount, but it seems to do the trick!

Finish it up!

Add the pasta to the sauce, and toss it! As you add the pasta to the sauce, it will immediately begin to thicken and become very creamy. Let the pasta cook in the sauce a minute or two, then serve immediately.

Yes, fettuccine is one of those dishes that should be eaten right off the stove. Simply plate it, and top with those crispy sprouts and bacon. Adding an extra dusting of parmesan never hurts either.

This recipe is all about the sauce, the sprouts, and the bacon. The sauce is buttery, a touch garlicky, herby, and so creamy. It’s my favorite combo.

The crispy Brussels sprouts are a game-changer. Their flavor is intense, but the texture is almost chip-like. And the bacon? Well, it adds a saltiness that keeps everyone coming back for seconds.

Nothing beats this one. Perfect for an autumn Wednesday night, or maybe save it for a Friday night? Honestly, it’s delicious any night of the week…so make when this dish when it suits you best…and enjoy!

Ingredients

Instructions

  • 1. Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente. Drain.
    2. Meanwhile, cook the bacon in a large skillet over medium heat until crisp. Drain onto a paper towel. Add the Brussels sprouts, cut side down, and season with salt and pepper. Cook until the sprouts are crisping on the edges, 3 to 4 minutes. Toss the sprouts, add the olive oil and cook another 2-3 minutes, until crisp. Remove the Brussels sprouts from the skillet to a plate.
    3. To the same skillet, melt the butter over medium heat, cooking until the butter begins to brown, about 3-4 minutes. Reduce the heat to low, add the garlic, oregano, sage, and a pinch of crushed red pepper. Cook 1 minute, then pour in the milk and cream. Add the cream cheese. Whisk until smooth. Bring the sauce to a gentle simmer and cook 5-8 minutes, until thickened slightly. Stir in the parmesan and nutmeg. Season with salt + pepper. Toss in the pasta and cook 3-5 minutes, then remove from the heat.
    4. Divide the fettuccine between plates and top with crispy Brussels sprouts, and bacon. Eat and enjoy immediately.

Notes

To Make Vegetarian: simply omit the bacon and start the cooking process with the olive oil and brussels sprouts.

    I made this recipe & it was fabulous! It ended up taking a lot longer to prep than 15 minutes, but was worth the wait. I added shredded rotisserie chicken.

    I will definitely be making this again!!

  2. 5 stars
    This recipe is INSANE. So so good. I added a bit of Gouda too because I had some on hand and it truly tasted like something I’d eat at a restaurant. Thank you for another incredible dish!!

    1. Hi Bailey! Thanks so much for trying out this recipe, so glad to hear you enjoyed it and even added your own little twist! xTieghan

  3. 5 stars
    Love this recipe! So easy and so delicious! I added mushrooms and chicken to the recipe and it turned out amazing! Definitely making it again!

  4. I cannot tell you how many times I’ve made this fabulous recipe. We eat it all the time and every time it just gets better. Thank you so much for sharing this recipe. Who knew that Brussel sprouts would go so well with pasta. I have even prepared the sprouts as instructed in this recipe and put them on homemade pizza with whipped cream /fontina cheese white sauce and it’s to die for. Thanks for opening up my eyes to new possibilities with an old favorite veggie.

    PS I added sauteed sliced mushrooms to the pizza and it was great. Might give mushrooms a try in the pasta dish next time.

    1. Hey Gale,
      Awesome! I am so glad this recipe was enjoyed and I really appreciate you giving it a try! Have the best week:) xTieghan

  5. I’ve attempted this recipe 4 times, 3/4 times the sauce curdled and became chunky as soon as I added the noodles to the sauce 😢😢😢😢. I tried letting the noodles drain and dry the excess water off well and it still happened. The one time the sauce stayed smooth it was delicious.

    1. Hey Amelia,
      So sorry about this! Is your heat on high when adding the noodles? This can cause the sauce to curdle, try keeping your heat on low. I hope this helps! xTieghan

    DELICIOUS! I paired this with HBH Chicken Parm and my guest loved it! Make this and your guest will be wowed!

  7. Hi Teighan,
    I was so excited to make this tonight, I used lactose free milk and coconut milk. But it seemed to clump together and not turn saucey like your pictures do! Do you have any trips for what I might have done wrong?

    Cheers!

    1. Hey Alicia,
      So sorry you had issues with the sauce, I haven’t tested this with dairy free ingredients so that could have been your issue. So sorry! xTieghan

  8. Attempted this recipe and it didn’t quite go as planned. The cheese seized up into clumps and it was watery not creamy. I did use 2% milk instead of whole. I wonder if I didn’t brown the butter long enough? Or maybe I let it simmer too long before adding pasta?

    1. Hey Anna,
      So sorry about this! Next time, try adding using whole milk in place of the 2%. Also, I know if can be a pain, but I like to shred my cheese by hand, it makes a huge difference in melting. I hope this helps for next time! xTieghan

    I have made many of your recipes and I have to refrain myself each time from telling you how delicious the food is, you’ve definitely increased the quality of life for my family and I. Flavorful and perfectly balanced and made with basic pantry ingredients. I just made this today after coming home from work and it was so delightful. Thank you so much for all your recipes.

    1. Hey Karen,
      I am thrilled that you enjoyed the recipe, thanks for making it! I hope you have an awesome weekend:) xTieghan

    1. Hey Caroline,
      I am thrilled that you enjoyed the recipe, thanks for making it! I hope you have an awesome weekend:) xTieghan

    1. Hey Aubree,
      So sorry you had issues with the sauce! Was there anything you adjusted in the recipe? Let me know how I can help! xTieghan

    I tried this recipe tonight and it was SO good! Truth be told, I skipped the bacon and Brussel sprouts and just went with traditional Alfredo. I accidentally even added too much heavy cream (1 cup vs 1/2c called for) and it still turned out perfect when letting it simmer for the whole 8 minutes. This was my first time freshly grating some fresh Parmesan, and WOW! What a difference it makes!! Definitely worth the extra time. Look forward to trying more of your recipes soon!

    Tiegan knocked it out of the park AGAIN!!! I was skeptical about the coconut milk, it just sounds so wrong for Alfredo. I have also always snubbed my nose at Alfredo sauces with cream cheese in them. I took a chance on this recipe because every one of hers I’ve done has been outstanding. I used coconut milk and half and half. I skipped the olive oil and used the bacon grease. The applewood smoked bacon gave the whole dish a nice smokiness. Went with reggiano. This was absolutely delicious.

    1. Hi Christina! I am so happy this recipe turned out so well for you! Thank you so much for trying this one! xTieghan

    I’ve made so many of your recipes and have loved them all! The flavor of mine was not as cheesy as I was expecting, but I think this could’ve been due to the Parmesan I was using.

    I was wondering if you think this recipe would freeze well as it made quite a bit for one person to eat?

    1. Hey Nina,
      Thanks for giving the recipe a try! Yes, you can certainly freeze this. Please let me know if you have any other questions! xTieghan

    This is so creamy and delicious! My husband said he prefers “normal” alfredo that’s saucier, not so thick, and doesn’t taste like cream cheese.. but I loved this alternative. I also didn’t think it tasted like cream cheese at all. It did take me a bit longer to cook overall (the brussels spouts needed a few more minutes, as did the sauce). The only change I’ll make next time is adding more brussels sprouts and bacon because I love them and didn’t get enough.

  14. 5 stars
    DELICIOUS!! Another recipe that is being bookmarked for future dinners. Really simple to make and so flavorful. It was a hit in my home!!

  15. Adding to our dinner rotation this week – CANNOT wait!😋
    Just wondering – do you store the leftover bruiser sprouts and bacon separate from the pasta then?

    1. Hey Corrianne,
      You certainly can store them separately, but it definitely is necessary. I hope you love the recipe, please let me know if you have any other questions! xTieghan

  16. Something went VERY wrong with this recipe…. I’ve made so many HBH recipes with no problems, but this one….what on earth happened? The butter and garlic mixture did not blend with the milk at all and stayed separated. Then adding in the cheese made the separation worse! The Parmesan clumped and turned to rubber, the butter separated from the cream/milk, and it was just gross. But hey at least I had bacon to eat! Any ideas what went wrong?

    1. Hey Mere,
      So sorry you had issues with the recipe. Did you adjust the recipe at all? Use a different cooking method? I haven’t had anyone else with these issues so I’m not sure what could have happened. Please let me know how I can help! xTieghan

    Délicieux! J’adore les choux de bruxelles et ils sont très bien mis à l’honneur dans cette recette!

  18. 5 stars
    I made this tonight and it was excellent! The flavors were wonderful and I see what you mean about the cream cheese. It was delicious. Thank you for sharing. I’ll definitely be making this one again!

  19. Hi – just a quick question – do you drain off all of the bacon fat before cooking the brussel sprouts and cook them in what is left (before adding olive oil – a light skim of bacon fat), or leave the fat and cook them in that? thanks!

    1. Hey Abigail,
      Either one is fine to do:) I hope you love the recipe, please let me know if you have any other questions! xTieghan

  20. Ohh I made this the other day and it was everything we needed! Há, such a comforting autumn meal. Thanks for the recipe dear Teagan! We warmed up the leftovers the next day for lunch, as we’re working from home in the Netherlands, and gave the sprouts and bacon a little grill in the oven. Delicious!! Thanks 🙏🏼

  21. This was seriously SO GOOD! and So easy! My fiancé hates brussels sprouts so we grilled up some chicken for his substitue. So so tasty we will definitely make this many times! – New follower @penny_foryourpots

    1. Hi Penny! I am so happy this recipe turned out so amazing for you!! Also, thank you for the follow! I cannot wait to see what you make! xTieghan

    I made this pasta with bacon and brussel sprouts for dinner tonight and it was absolutely fabulous. I am a cook from way back and I sometime adjust recipes where I think they need to be adjusted. However, this recipe didn’t look like it needed any adjusting so I made it just as written and I even used my measuring cups and spoons, and I almost never do that. But, I am so glad that I did because it was just perfect. Will definitely be making this again soon. Thanks for sharing.

  23. 5 stars
    Very Very yummy! I made this and also added broccoli (for my kiddos). The meal came out perfectly, the bacon and Brussel sprouts were a great pair. AND beside the pot to boil the noodles-only one pan, which was so nice for clean up!

  24. I made this pasta tonight for my boyfriend and I. I used broccoli instead of Brussel sprouts and I added some church, it was SO GOOD!!!! We made tons and we’re already so excited for lunch tomorrow!

  25. 5 stars
    So good! My husband was so impressed with the sauce from scratch! The bacon and Brussels were just perfect ( I did cook the Brussels in some bacon fat because I couldn’t resist!) and may make for a yummy side dish at thanksgiving! As always thank you Tieghan for a satisfying homey dish!

  26. 5 stars
    This recipe was amazing. I used shirataki noodles to make it “keto friendly”. The browned butter really adds a layer to the alfredo sauce that I’ve never had before and the sage + nutmeg combo was perfect. This recipe is definitely going into the rotation. 🙂 Thank you!

  27. 4 stars
    That’s a real good recipe!! I just wonder if its normal if the parmesan cheese didn’t really met once in the sauce? I wonder what I did wrong?

    Thank you!!

    1. Hey Sophie,
      Thanks so much for giving the recipe a try! I would recommend using really high quality parmesan and grating it yourself. I hope this helps for next time! xTieghan

  28. Super delicious! I made it with coconut milk as suggested and gluten free pasta and it was so good! Thanks for the recipe

  29. I wish there was a section where people could actually comment on the recipe if they made it then another place for people who want to tell you it sounds yummy 😛

  30. 5 stars
    Super tasty! I replaced pasta with spaghetti squash and it was yummy! I also made it with the coconut milk, I don’t think my parents noticed! Lol! It was delish!

  31. Hi Tieghan!
    Firstly off — I love everything you make, thank you this endless bounty of creativity and deliciousness. I’m going to attempt to make this for someone who is lactose intolerant. Do you have any recommendations on what could be subbed for the cream cheese?
    Warmest regards,
    Alex

    1. Hey Alex,
      I would try looking for a dairy free cream cheese. I hope you love the recipe, please let me know if you have any other questions! xTieghan

    3rd recipe of yours this week and again everyone loved it. Thank you 🙂 I wouldn’t have thought of using these herbs in Alfredo

    1. Thank you so much Alejandra! I am really glad you have been loving this and other recipes of mine! I hope you continue to! xTieghan

  33. 5 stars
    This was fantastic! Used coconut cream to replace all of the milk and the fettuccine flavor was totally perfect! Great combination of flavors, highly recommend!

  34. This was amazing !
    My kitchen was a complete mess but so worth it.
    I did slice the Brussels sprouts and they were tender and delicious!

  35. This recipe looks delicious but, um, hello! Wipe the skillet after cooking bacon?! Why would you not fry the Brussels Sprouts in bacon drippings, rather than olive oil?? (Maybe there’s a reason I’m not aware of). 🙂 Both ways sound yummy (crispy Brussels are the best!) but personally, I would not waste that bacon grease. 🙂

    1. Hi Ellary! You can definitely cook them in the bacon grease! It is just a bit healthier to cook in olive oil haha. I hope you love this recipe! xTieghan

    Looks wonderful. Recently did a sausage ravioli with Alfredo and Pancetta. Delicious. So I know I’ll enjoy this one.

  37. 5 stars
    Hi Tieghan. This is truly a bowl of “cozy” and “comfort.” A perfect Fall dish that would warm any soul up. I love the twist on Fettuccine Alfredo. Thanks so much for sharing.

  38. This sure does look yummy! I love whole grain pasta so much.I need to look for the fettuccini in whole grain.

  39. I love you pasta dishes, so I will definitely ear-mark this one for the weekend when my partner (also a chef) is working, as he’s not a big pasta fan, however he did like the creamy tortellini soup that I made last week.

    1. Hi Colleen! I am so glad you both enjoyed the tortellini soup! I hope you love this one just as much.. or more! Thank you! xTieghan

    1. Hey Alexandra,
      Yes that would be great! I hope you love the recipe, please let me know if you have any other questions! xTieghan
