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!

    I made this last night and it was amazing!! The only thing I would say is to allot a lot more time to caramelize the onions. Took me about 40 minutes to truly get the caramelization, which is a must!

    Today I did the pasta and it was soooo delicious. I skipped the cheese inside,added vegan coconut sour cream and put vegan mozzarella on top but either way it is my new favourite COZY recipe.

  3. Omg this sounds amazing—like all your dishes! However, what can I substitute for the Cabernet if I do not use alcohol? Thanks so much!

  4. Looks amazing! Do you have suggestions on specific brands of gruyere cheese? I have tried a few in the past but never loved the ones that I’ve bought. I’m hesitant to keep trying.

    1. HI! I love to use Murray’s Cheese or Emmi Cheese. Please let me know if you have any other questions. I hope you love this recipe! Thank you and happy holidays! xTieghan

  5. Made this dish tonight and just sat down feeling very satisfied! It’s amazing! I’ve made many of your recipes and keep coming back to your page for new ideas. Thank you for sharing and keep them coming!

    1. HI! You can freeze this. I would freeze just before baking, then thaw and bake as directed. Please let me know if you have any other questions. I hope you love this recipe! Thank you and happy holidays! xTieghan

    1. HI! I would recommend using an equal amount of maple syrup or brown sugar. Please let me know if you have any other questions. I hope you love this recipe! Thank you and happy holidays! xTieghan

  6. I’m going to give this recipe a whirl. It sounds delish.

    I have one question though – why use chicken broth? It seems to me that beef broth is more consistent with the use of a rich red wine and the overall flavour profile of French onion soup. I’m gonna go with the beef broth.

    1. HI! Beef broth just turns the pasta weird color. If you dont mind the color, go ahead and use beef broth. Please let me know if you have any other questions. I hope you love this recipe! Thank you and happy holidays! xTieghan

  7. This sounds delicious! Can I make this ahead with out topping it with the cheese? Defrost and finish cooking with the cheese on Christmas Day?

    Thank you,

    Marilyn

    1. HI! Yes, making ahead, freezing, then thawing and baking when ready works wonderfully. Please let me know if you have any other questions. I hope you love this recipe! Thank you and happy holidays! xTieghan

    1. HI! I am sure spaghetti squash will be great! Just omit the broth and steps for cooking the pasta and instead toss in cooked spaghetti squash, then bake. Please let me know if you have any other questions. I hope you love this recipe! Thank you and happy holidays! xTieghan

  8. Hi Tieghan, Love you! You’ve transformed my cooking from bachelorette to bonafide chef. So…Amazon Fresh never seems to have fresh mushrooms…is there any way their bag of frozen mixed mushrooms would work for this? Thanks in advance! xx

    1. HI! You are way too kind! Thank you!

      The frozen mushrooms will be great I am sure! Please let me know if you have any other questions. I hope you love this recipe! Thank you and happy holidays! xTieghan

    This was the first recipe of yours I made YEARS ago, and it’s still my absolute favorite to this day! I’ve baked this for many, many folks from family members to friends to new acquaintances and every single one of them has loved it. This is in my permanent rotation when the weather gets cold (or when I’m in need of a good hug!). Thank you so much!
