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!

  1. I so wanted to love this recipe. I followed the directions to a “T”. I had to add two 2 more cups of broth while cooking the pasta because the dish became dry and was sticking. Once the pasta was aldente I added the cream and cheese and slipped it into the oven. It was dry and needed more flavor. If I cooked it again, I would cook the pasta separately in beef broth, then add it to the onion and mushroom mix. I would use more onions and mushrooms to make the pasta to onions and mushrooms better.

    1. Hey Sue, I am sorry you had some trouble with this recipe and ended up not enjoying it too much. Is there any questions I can answer for you? I am not sure why your pasta took so long to cook and ended up dry. What cut of pasta did you use? Was there anything you did differently? Hoping I can help you love this recipe! Thank you and Happy New Year! xTieghan

    Absolutely perfect. I made this tonight and my super picky husband and child both LOVED it! This will be going into the rotation. Thank you thank you thank you for making this recipe ??

    I made this this evening with leftover cream & cheese from Christmas. I didn’t add cheese to the sauce but dotted the top with mozzarella & blue cheese, and used a bit less cream. I also used shiitake mushrooms instead of crimini. Anyhow it was delicious! Will definitely be making it again.
    The recipe says to use cayenne, however it’s not in the method. I left it out because I’m not sure it would benefit from it. Thanks for sharing. X

    This was amazing! Didn’t have any wine, substituted cranberry juice and used beef stock. Perfect pasta dish for a winter night.

  5. I am going to make this for my family’s Christmas get together next week. Do you leave the bay leaves in the mix or do you remove them?

    Made this and the flavor is AMAZING!!! My son in law is considering this for his birthday dinner (instead of brisket!!) Try it, you won’t be disappointed!

    Made this last night to rave reviews from my kids…and wondering who’s going to score the leftovers for lunch!
    Due to allergies I subbed in chicken for the mushrooms and 100% cran juice for the wine. Delicious!!
    Thank you so much for your phenomenal recipes!
    Happy Holidays!!

    I made this last week and was very sad when it was all devoured. Folks, don’t leave out the Gorgonzola cheese!! It makes this dish so yummy. Unless, of course, you really don’t like Gorgonzola cheese. But, in my opinion, it makes this dish extra special!!

    I have made many Half Baked Harvest recipes (and they have all been DELICIOUS) but this one takes the cake. I made it for dinner last night and had to stop myself from eating the entire pot and had more for lunch today. It is everything you would want on a cold winter night- cheese, mushrooms, red wine..I could go on. Thank you ?

    1. YES! That is so amazing to hear! I am so glad you loved this one, Mary! I hope you love the rest you try as well! xTieghan

  10. Made this for my family last night. Huge success! Everyone LOVED it! Super easy to make. Thanks for sharing all your recipes. I just purchased your new cookbook…one for myself and one for my daughter-in-law. Looking forward to trying all your recipes. Merry Christmas!!

    Truly the ultimate comfort food. Enough work for it to feel like you’re cooking something special, but not so much that it feels like a burden. I used the Gorgonzola and doubled the thyme. I made this with two medium sized onions. I’ll add a third next time. I cooked this in an enamel coated cast iron Dutch oven. If you love French onion soup and macaroni and cheese, this recipe is a must.
