Ingredients

Here’s a list of what you need to make this pasta:

How to Make French Onion Pasta

Don’t be intimidated by this dish! It’s actually pretty simple. Just follow these steps:

  1. Caramelize the onions. Melt the butter and olive oil in a large pot. Add the sliced onions and salt, and cook until deeply caramelized, about 30-40 minutes.
  2. Add the aromatics. Stir in the garlic, thyme, and white wine. Simmer until the wine is mostly evaporated.
  3. Cook the pasta. Add the Worcestershire sauce, beef broth, water, and pasta to the pot. Bring to a boil, then simmer until the pasta is al dente and the liquid is mostly absorbed, about 15 minutes.
  4. Finish the dish. Turn off the heat and stir in the heavy cream and Gruyère cheese until melted. Season with salt and pepper to taste.
  5. Serve hot. Garnish the French onion pasta with chopped parsley and extra Gruyère. Serve immediately.

Tips for the Best French Onion Pasta

These tips take this pasta over the top!

  • Go low and slow. Take your time caramelizing the onions over low heat. It can take up to 40 minutes.
  • Preserve your pasta water. Reserve some before draining in case you need to thin the sauce.
  • Splurge on the cheese. Opt for high-quality cheese for the best flavor and texture in the dish.
  • Give it a finishing touch. If desired, place the finished pasta under the broiler for a few minutes. It’ll give you a golden-brown, bubbly cheese topping.
  • Try some fun variations. Try adding cooked chicken, bacon, or mushrooms. Use vegetable broth and skip the dairy to make it vegan. Or experiment with different pasta shapes.

How to Store

If you have leftover pasta, you can enjoy it at a later date with these storage tips:

To Store: Keep the pasta in an air-tight container in the refrigerator for up to 4 days.

It’ll absorb the sauce as it sits, so you may need to add a splash of broth or water when reheating.

To Freeze: Let the dish cool completely. Then, transfer to freezer-safe containers or bags, removing as much air as possible before sealing.

You can freeze French onion pasta for up to 3 months. However, the texture of the pasta and sauce will change once thawed and reheated. 

To Reheat: Gently rewarm in a saucepan over medium-low heat. Stir occasionally and add a bit of broth or water to loosen the sauce if needed.

You can also reheat individual portions in the microwave, stirring every 30 seconds.
