Creating One Pot French Onion Pasta is straightforward and enjoyable. Follow these simple steps:

1. Sauté the Onions: In a large pot, heat olive oil over medium heat. Add the sliced onions and sauté for about 8-10 minutes until they become soft and caramelized.

2. Add Garlic and Thyme: Stir in the minced garlic and thyme. Cook for an additional minute until fragrant.

3. Combine Liquids: Pour in the beef broth and water, stirring well to combine. If using soy sauce, add it at this stage for extra depth of flavor.

4. Cook the Pasta: Add the pasta to the pot, ensuring it is submerged in the liquid. Season with salt and pepper to taste. Bring the mixture to a boil.

5. Simmer: Once boiling, reduce the heat to low. Cover the pot and simmer for about 10-12 minutes, or until the pasta is al dente. Stir occasionally to prevent sticking.

6. Add Cheese: When the pasta is cooked to your liking, remove the pot from the heat. Stir in the shredded Gruyere cheese until melted and well combined.

7. Taste and Adjust: Check the seasoning and adjust with more salt and pepper if necessary.

8. Garnish and Serve: Sprinkle with chopped parsley for a fresh touch before serving.
