This One Pot Creamy French Onion Pasta Bake is the ultimate cold weather comfort food. Think French onion soup, with the addition of pasta, a creamy sauce, and melty Gruyere cheese. The secret to this one-pot pasta is a little bit of wine, to keep those classic French onion soup flavors we love so much. This pasta dish is great any night of the week but is also perfect for your next dinner party. Every last bite is delicious…everyone LOVES a GOOD cheesy baked pasta…especially when caramelized onions are involved. This dish will be your new go-to when serving family and friends over the holidays…and other times throughout the year too.

It’s that time of year when all I want to be cooking, eating, and sharing with you is comfort food recipes. As I type this, I’m looking out my NYC window to freezing cold rain. The question I keep asking myself is, when will the rain turn to snow? I’m channeling my mom and little sister (snow dance please!) and putting out the positive thoughts for snow. Because what’s more magical than a snowy NYC in December? It’s going to happen. I will document it for you all.

Regardless of rain or snow, December days call for only the best comfort foods and easy dishes that we can feed our friends and family. When I return home from New York, I’ll only have a week or so until the bulk of my family members start arriving for the Christmas holiday. With that in mind, I’ve been working to come up with some creative recipes to feed everyone this year. If there’s one thing I’ve learned over my many years of serving large groups, it’s that pasta dishes are key.

Most everyone enjoys pasta and what I love about a baked pasta is that I can prepare everything in advance if need be. This pasta is extra special though…if you love French onion soup, you will absolutely love this pasta bake. It has all the rich flavors you get in a bowl of steaming French onion soup. But made better with the addition of pasta and a touch more cheese. You simply cannot go wrong.

Here are the details.

Start with the onions. They need to be deeply caramelized, just as you do when making French onion soup. My secret to the best caramelized onions? Butter, a touch of honey, and in today’s case…dry red wine.

The butter is used for obvious reasons…fat, flavor, and deliciousness. The honey helps to cook and caramelize the onions faster. I always find these ingredients to be key when trying to achieve the perfect caramelized onions.

Now, the wine. Use a dry red wine. Cabernet Sauvignon is pretty traditional in most French onion soups, so I wanted to carry those flavors over into this pasta. You’ll cook about half of the wine into the onions. This not only helps the onions to caramelize quickly and evenly, it also infuses the onions with incredibly rich flavor.

If you prefer not to cook with wine, I recommend using about half a cup of pomegranate or cranberry juice when caramelizing the onions. For the remaining amount of wine called for (another half cup), use chicken or vegetable broth.

Once the onions have deeply caramelized, add mushrooms, garlic, and fresh thyme. Cook all together until the mushrooms have caramelized. Add the broth and dry pasta right into the pot. I know it may seem odd, but trust me, it works. Just bring the mix to a boil and cook until the pasta is al dente. Cooking the pasta together with the sauce only takes a few minutes and saves you from having to break out another pot. It’s my secret to keeping pasta recipes simple and easy.

When the pasta has cooked, add the cream and a little cheese. Transfer everything to the oven and bake until the cheese on top is melty and golden and everything looks and smells delicious.

The best thing about one pot recipes?

Everything starts in one pot, and ENDS in the very same pot. YES. Dishes be gone!! Granted, I tend to transfer my dishes to a baking dish for a prettier look, but if using an oven safe pot, you can bake this right in the very same pot you started with.

One and done and so easy. It’s just what’s needed this time of year, easy dinners that are incredibly delicious.

Serve this with…

Since this is such a hearty pasta, I love serving this with a bright salad. This pretty salad is always my favorite (I leave the chickpeas off when serving this as a side salad).

Of course, you can also add some bread, which is never a bad idea in our house.

With that, you’ll have a complete dinner that will be great any night of the week. My recommendation? Serve this up on the next super cold night when you’re craving a steaming bowl of soup…but also a plate of mac and cheese. This pasta is soup and mac and cheese in one. It’s creamy, cheesy, and swirled with caramelized onions. So…it’s insanely GOOD!

Ingredients

Instructions

  • 1. Preheat the oven to 400 degrees F.
    2. Melt the butter, onions, and honey together in a large pot over medium-high heat. Cook, stirring occasionally until softened, about 5 minutes. At this point, you want to slowly add 1/2 cup of the wine, 1/4 cup at a time, until the wine cooks into the onions. Continue to cook another 8-10 minutes until you've used the 1/2 cup of wine and the onions are deeply caramelized.
    2. Add the garlic, mushrooms, thyme, and season with salt and pepper, cook another 3-4 minutes. Add the remaining 1/2 cup wine, the broth, Worcestershire sauce, bay leaves, and the pasta. Bring the mixture to a boil. Stir frequently until the pasta is al dente and the broth has been absorbed, about 8-10 minutes. Stir in the cayenne, cream, gorgonzola, if using, and 1/2 cup gruyere cheese. Remove from the heat.
    3. If needed, transfer the pasta to a baking dish. Top with the remaining gruyere cheese.
    4. Transfer the baking dish to the oven and bake 20 minutes or until the cheese has melted and is lightly browned on top. Cool 5 minutes before serving. Serve with fresh thyme. Enjoy!

    Loved this! One of my favourite recipe finds. I don’t like mushrooms so substituted diced courgettes which I think worked great. Have made a couple of times now and looking forward to it for dinner tonight!

    Oh.my.goodness.
    Made this tonight and it was DIVINE. Such a perfect decadent Sunday dinner.
    It tasted exactly as I hoped it would (like a bowl of French onion soup but even better because…pasta!).
    I left out the gorgonzola and used baby portabella mushrooms. Otherwise followed the recipe exactly.

    1. Hey there,
      Thanks so much for giving this recipe a try, I am delighted that it was enjoyed! Have a fantastic week! xTieghan

  3. I’ve made this recipe before and it’s AMAZING! I’m going to make it again for my family but they would like some sort of protein in it. I was thinking top sirloin? What would you suggest? And at what point in the recipe would you add the protein?

    1. Hey Morganne,
      I would recommend using cooked chicken. I hope you love the recipe, please let me know if you have any other questions! xTieghan

    Really loved this one! The caramelized onions add awesome flavor. Left out the mushrooms (not a fav).

    1. Hey there,
      Thanks a lot for giving the recipe a try, I am delighted that the recipe was enjoyed! Happy Sunday! xTieghan

  5. Is there a way to make this ahead of time to travel with to a friends and finish baking there? If so, what do you recommend changing in the process?

    1. Hey Liz,
      I would make up until baking, cover with foil, and then bake and your friend’s house. I hope you love the recipe, please let me know if you have any other questions! xTieghan

  6. Hello! This sounds delicious and want to try it soon, but I am wondering if it can be made the day before. Thank you!

    1. Hey Jacquie,
      I would go ahead and assemble up until baking and then cover and keep in the fridge until you are ready to bake. I hope you love the recipe, please let me know if you have any other questions! xTieghan

    This turned out quite well in the end, but at least in the pan I used (a high-sided skillet that I use all the time for one pot pasta dishes), there wasn’t near enough broth to cook a pound of pasta, so I had to add about 2 more cups. I also used button mushrooms instead of cremini, and omitted the gorgonzola.

    1. Hey Helen,
      Thanks so much for giving the recipe a try, I am thrilled that it was enjoyed! Happy Valentine’s Day❤️ xTieghan

  8. I will be making this pasta dish this weekend for a retirement party. Can I make it ahead of time, refrigerate it overnight and bring it back to room temperature before baking? Can’t wait. Looks amazing!

    1. Hey Sheila,
      Congrats!! Yes, that will work well, no need to bring it back to room temp, you can bake from the fridge. I hope you love the recipe! xTieghan

    This was a hit when I made it for dinner. Used 2.5 onions and made it all in a Dutch oven. The flavours are so insanely good, I will definitely be remaking this. The leftovers did not last long!!

  10. I’m a single guy with limited cookware. Can I do all the cooking in a regular pot on my stove then pour it all into a cheap aluminum pan for the baking process? Thanks!

    1. Hey John,
      Sure whatever pot you have works great and then transfer to an oven safe baking dish. I hope you love the recipe! xTieghan

  11. Looks delicious! I want to try it this weekend. Can you do all the stove parts ahead of time and bake later? I was thinking of prepping it in the morning and then baking for dinner. Thank you!

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