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.

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.

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.

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!

Because OH MY FREAKING GOODNESS THIS TASTES ABSOLUTELY AMAZING.
Your recipe made its way to me in Germany and let me tell you: I’ll spread the word.
Thank you for sharing this wonderful recipe!
AH!! YAY! So happy you loved it and commented Valerie! Thank you so much!! (:
Do you think white wine would work well instead or red?
Hey Kayla,
I am sure white wine will be great! Let me know if you have questions, thanks!
I love your pics of this dish! Cannot wait to try it! Where is your wooden spoon from?? I am always looking for more great cooking utensils!
Thank you so much, Claire! I actually found that spoon at a flee market in Florida. That said I am loving all of the wooden spoons from Staub right now! 🙂 Let me know if you have questions. Thanks!
This pasta was amazing. I’ve tried my fair share of delicious looking pasta recipes on Pinterest and this was one I was actually able to pull off! So delicious I’m dreaming about eating it again. Used Parmesan because I didn’t have the other ones on hand, but it still came out great! Thanks for the great recipe! This one is definetly going in the books.
Aw thank you!! SO happy you like it Kelsie!
I was really excited about making this. The directions were easy to follow and it smelled delicious. Unfortunately, my little guys didn’t like it ( and my son eats everything). I wouldnt say this is kid friendly… At least in my household. I liked it but found it a little too rich, maybe half cream and half milk if I make it again. Or thinken it with a bechamel sauce.
Will this work well as a make ahead dish and bake the next day? What oven temp and how long would you suggest? Also, instead of the cream, what do you think about adding a alfredo sauce?
HI!! Yes, you can prep this advance and then bake at 350 for 20-25 minutes or until warmed through and the cheese is melted. The sauce will be a little thicker if you use alfredo sauce, but I am sure that will be great! Let me know if you have other questions, thanks!
Hi! I want to make this for dinner this week. Do you leave the bay leaves and thyme sprigs whole and remove at the end, or chop up and mix in? Thanks, looking forward to this! ?
Would this work with a lighter cheese, like Muenster?
Yes, muenster will be fine. Hope you love this! Thanks!
Had to comment on this recipe. It is of restaurant quality and has an incredible flavor! We all loved it. Thank you for sharing!
THANK YOU! That means a lot!!
So good! We had it for two nights in a row and it was just as good as leftovers.
This pasta is fantastic!! I cooked my pasta separately in a mix of chicken broth and water. I added the bay leaves as well. I was thinking about freezing some and baking later. Do you think that would work?
I think freezing will work out great! So happy you loved this!
Excellent flavors, but the pasta made me feel so heavy afterward. I would make this again but add cooked chicken near the end of the pasta cooking and a big salad. Couldn’t stop eating.. 🙂
LOL! Thanks so much!
I found this on Pinterest. I did not have a Dutch oven but I used an 8qt saucepan. This is very delicious. Couldn’t find red cooking wine so I used Barefoot Rich Red blend. It was delicious.
Any tips for cooking the pasta water part? There was no WAY my pasta was going to absorb all of that liquid and it started to get seriously overcooked. The flavors were incredible but I was left with overdone pasta and a really thin sauce. Any way I could–gasp–use two pots and cook the pasta separate? Appreciate any help!
Hi! Yes, you can cook the pasta in a separate pot. Just omit the chicken broth and water and then stir in the pasta. Hope that helps and Happy Holidays! 🙂
