Creating the One-Pot French Onion Pasta is simple if you follow these steps:

1. Sauté Onions: In a large pot or deep skillet, melt the butter over medium heat. Add the sliced onions and a pinch of salt. Cook slowly until they are caramelized, stirring occasionally, for about 20 minutes.
2. Add Garlic: Once the onions are beautifully golden brown, add the minced garlic and cook for an additional 1-2 minutes until fragrant.
3. Deglaze the Pot: Pour in the Worcestershire sauce and scrape any bits off the bottom of the pot to incorporate that lovely flavor.
4. Combine Broth and Seasonings: Add the beef broth, dried thyme, salt, and pepper. Bring the mixture to a gentle boil.
5. Add Pasta: Once boiling, add the pasta. Stir well and lower the heat to a simmer. Cook according to package instructions, usually around 8-12 minutes, until the pasta is al dente and has absorbed much of the broth.
6. Add Cheese: Once the pasta is cooked, turn off the heat and stir in the Gruyère and Parmesan cheese until melted and creamy.
7. Adjust Seasoning: Taste the dish and adjust seasoning if necessary, adding more salt and pepper to meet your liking.
8. Garnish: Serve the pasta hot, garnished with freshly chopped parsley for a touch of color and flavor.

By following these steps, you’ll create a comforting bowl of One-Pot French Onion Pasta that’s sure to impress.
