Why You’ll Love This Pasta
- One-pot wonder. You’ll roast the chicken separately, but the rest is all cooked in one pot for easy cleanup!
- Rich Flavor. Think caramelized onions, nutty gruyere, white wine, and a touch of herbs for a fulfilling bite.
- Creamy goodness. Melty, nutty Gruyere blends with heavy cream to make one irresistible, creamy sauce.
French Onion Pasta Ingredients
- Chicken thighs are what I use for this recipe, but you could use chicken breasts instead.
- Olive oil is used for the chicken and for the sauce.
- Salt & Pepper to season.
- Butter for the onions.
- Yellow Onions are always my go-to, but Vidalia onions would work, too.
- Cremini Mushrooms are my choice, but white button mushrooms would also work.
- Fresh thyme or use dried thyme instead.
- White wine, or you could use some apple cider vinegar or sherry vinegar instead.
- Short pasta like orecchiette, but mezze rigatoni, farfalle, or fusilli would do the trick as well.
- Beef broth
- Heavy cream
- Freshly grated gruyere cheese will melt into the sauce much more smoothly.
- Fresh parsley
How to Make French Onion Pasta
- Prep. Preheat the oven to 400°F and line a baking sheet with aluminum foil.
- Season the chicken. Toss the chicken with olive oil, salt, and pepper and transfer it to the baking sheet; bake for 30 minutes. When it’s done, remove it from the oven and chop the chicken into bite-sized pieces.
- Caramelize the onions. Heat the olive oil and butter over medium heat. Add the onions and cook them over medium-low heat for 30 to 40 minutes until caramelized, stirring occasionally.
- Sauté the mushrooms. Add the mushrooms and thyme and cook until the mushrooms are golden brown. Add the white wine and stir until it has mostly evaporated.
- Cook the pasta. Stir the pasta and the beef broth into the mushroom mixture and boil. Reduce the heat to low and simmer for 8 minutes, stirring occasionally.
- Thicken the sauce. Whisk together the cornstarch and water and stir it into the pasta. Cook for an additional 2 minutes.
- Finish it off. Turn off the heat and stir in the chicken, followed by the heavy cream and the gruyere. Season with salt and pepper and serve.
Recipe Tips & Variations
- Keep the broth near you when caramelizing the onions. Add broth as needed if the pan starts to dry up.
- Be patient and caramelize the onions so they are a deep brown. The flavor will deepen with the color, and it takes some time to get to that.
- Keep stirring the pasta frequently as it cooks, or it will stick to the bottom of the pot.
- Use rotisserie chicken instead of roasting your own to save some time. Remove the meat from the bone and shred it or chop it up.
- Make it vegetarian, and leave out the chicken in this recipe.
- Add veggies like spinach at the end and let it wilt into the pasta dish. Or add diced, roasted asparagus or another veggie of your choosing.
- Try a different cheese if you want. Gruyere is reminiscent of French onion soup, but you can use freshly grated parmesan or pecorino.
How to Store & Reheat Leftovers
- Refrigerator. Once the pasta has cooled to room temperature, seal it in an airtight container and store it in the fridge for up to 4 days or in the freezer for 3 months. Thaw before reheating.
- To reheat. Transfer the leftover pasta to a baking dish, cover with aluminum foil, and bake at 350°F for 10-15 minutes or until heated through.

- Chicken: I prefer chicken thighs, but chicken breasts are a good alternative. Just tweak the cooking time. For a quick fix, swap in shredded rotisserie chicken.
- Mushrooms: Though I like to use cremini mushrooms, white button mushrooms are a good substitute.
- Wine Alternative: Instead of white wine, consider apple cider vinegar or sherry vinegar.
- Pasta: I love using short pasta like orecchiette, but rigatoni, farfalle, or fusilli work great too. Stir the pasta often while cooking to prevent sticking.
- Sauce: For a creamier texture, go for freshly grated gruyere cheese. You can also use parmesan cheese.
- Caramelizing Onions: Take your time with cooking the onions to achieve a deep caramelized color. Also, have beef broth handy when working with the onions, and add some in if the pan starts to look dry.
