Follow these simple steps to bring your One Pot French Onion Pasta to life:

1. Sauté Onions: In a large pot, heat olive oil over medium heat. Add the sliced onions and cook for 15-20 minutes, stirring often, until they are caramelized and golden brown.

2. Add Garlic: Stir in the minced garlic and cook for another 1-2 minutes until fragrant.

3. Pour in Broth: Add the broth, dried thyme, dried oregano, salt, and pepper. Bring the mixture to a simmer.

4. Add Pasta: Add the uncooked fettuccine or linguine directly to the pot, ensuring it’s submerged in the broth.

5. Cook Pasta: Cover and cook for 10-12 minutes, stirring occasionally, until the pasta is tender and has absorbed most of the liquid.

6. Add Cheese: Lower the heat and stir in the grated Gruyère and Parmesan cheese until melted and creamy.

7. Adjust Seasoning: Taste and adjust seasoning with additional salt and pepper, if necessary.

8. Serve Immediately: Garnish with fresh parsley if desired and serve hot.
