This simple Lemon Pepper Cajun Chicken Fettuccine Alfredo is a favorite with everyone. Classic, creamy fettuccini Alfredo with butter, garlic, and plenty of parmesan. Then topped with crispy lemon pepper cajun chicken. Every twirl of pasta melts in your mouth and the chicken adds a nice buttery, spiciness to every bite. It’s delicious.

Sometimes you have those recipes that you just know you’re going to love. I feel like this fettuccine will be that recipe for many of you. Creamy Alfredo pasta mixed with spicy, buttery cajun chicken, it’s a combo we all can love. 

Simple, but wow, so good, and the chicken really does add so much flavor. What I said above really stands true, everyone loves this dish.

The inspiration 

Growing up my dad often made fettuccini alfredo on Friday or Saturday night. It was always a special night when he made it because he didn’t make it that often. Or well, just not as often as he made say tacos. My dad has made a lot of tacos. 

I loved alfredo night, it always felt so fancy to me. Looking back I didn’t realize just how simple it was, especially my dad’s Alfredo. He kept his basic with lots of butter, cream, and parmesan. He also added cream cheese, which made it extra rich. 

I wanted to see if I could improve on his old skool, classic pasta. We love anything involving a little cajun seasoning around here, so adding in some cajun chicken sounded perfect.

The steps 

Before starting the chicken boil off the pasta. 

Next, toss the chicken in olive oil, homemade cajun seasoning (my recipe is in the notes), parmesan, and a big pinch of pepper. 

Sear up the chicken in a skillet with some butter until it becomes deeply golden and crisp. Then pour over some lemon juice and let it sizzle around the chicken.

Nothing fancy, but the smells coming from your skillet sure will be delicious. 

Now onto the pasta, this happens really quickly.

Use the same skillet you cooked the chicken in so you get all that yummy flavor. Add in a bit more butter and some garlic. Then pour in broth and milk (you can also use cream). I like to use broth and milk to create a still creamy pasta, but a pasta that has a nice amount of sauciness to it as well. It’s also a little lighter than using all cream or milk, so the alfredo isn’t quite as rich. 

Once the sauce has thickened, stir in the parmesan and pasta. I like to use linguine, but fettuccini is obviously great too.

And that’s it! Serve the chicken over steaming bowls of creamy pasta and top with additional parmesan and fresh parsley. Yummmm!

This recipe is all about the creamy sauce and that crispy cajun chicken. The sauce is buttery, a touch garlicky, and so creamy. And the crispy chicken…it’s a game-changer. Tender and delicious when thinly sliced and tossed in with the pasta.

It’s one of those chicken pasta dinners that feels like a dish you’d order at a restaurant. But it’s made at home and is even more delicious. Trust me.

    I’ve tried a lot of homemade Alfredo recipes, and this one is my absolute favorite! It’s just my husband and I, so I cut the recipe in half and it’s perfect! 🙂

    Every HBH I’ve ever made is so yummy! Really loved this one, but I couldn’t give it to my kids because they don’t like spicy 😂

    I made this last night for me and my bf. The chicken turned out wonderful and we both want to make it again! The sauce was simple. My adjustments were: adjusting my Cajun mix to have a bit less salt for next time, cutting the full chicken breast in half so they were thinner, only 1tsp of chili powder (we don’t care for lots of heat), and I’d thicken up the sauce some, it was really runny for me.

    1. Hey Keely,

    Holy cow. This is one of the most delicious recipes I’ve ever made. We could not stop eating it. Wow. Super easy and ingredients I usually have on hand. This will become a staple.

    1. Hey Jennifer,
      Fantastic!! I love to hear that this recipe was a winner, thanks for trying it out! I hope you had a great holiday weekend!🎆

  5. Hi Tieghan,
    I cooked this recipe today and it was scrumptious….but the sauce never thicken, it reduced a little. I used broth and heavy whipping cream because that’s the only cream I can find and the Parmesan cheese got clumpy. I did follow your steps, please advise what I can do to avoid this again.

    1. Hi Rose,
      Happy Monday!! I love to hear that this recipe was enjoyed, thanks so much for giving it a go! Sorry to hear you had some issues. Sounds like the sauce needed to simmer a little longer. Did you use freshly grated parmesan? It’s important to use fresh cheese, not the fake stuff:) xxT

    2. Same as Rose! Also, I wasn’t sure whether to use grated or shredded parm, so I used some of each.

    1. Hey Charlie,
      Happy Monday!! I love to hear that this recipe was enjoyed, thanks so much for giving it a go! xxT

  6. So so good! I doubled the recipe, and I would recommend doubling the Cajun seasoning. It makes it way too salty. But still an AMAZING recipe!

    1. Hey Emily,
      Happy Wednesday! I am thrilled to hear that this recipe was a hit, thanks a bunch for giving it a try! xx

    Holy cow! This is so good and super easy to make! I used tilapia instead of chicken and it turned out amazing. I’ll be making this again for sure!

    Delicious flavoring. Step four says milk instead of cream. The ingredient list was correct. I made the error of grabbing milk over cream after reading the step so my sauce did not thicken well. I have no doubt when I redo it will be perfect 🙂

    1. Hi Kristin,
      Happy Wednesday!! I so appreciate you giving this recipe a try and love to hear that it was enjoyed! Thanks for your feedback:) xT

    This recipe (like literally every other HBH recipe I’ve ever tried) is SUCH a smash hit. Omg the chicken is mouth-wateringly delicious, and the alfredo is decadent but somehow still doesn’t feel too heavy at all. LOVE LOVE LOVE.

  10. This is a wonderful and versatile recipe! Great with chicken as written, yummy subsisting with shrimp, and a wonderful cream sauce base for a variety of pasta uses. Recently made a version with no meat, adding green and red peppers, shallot, and mushrooms. Highly recommend giving this one a try!
