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

1. Melt Butter: In a large pot or Dutch oven, melt the butter over medium heat.
2. Cook Onions: Add the sliced onions and sugar. Sauté for about 10–12 minutes, stirring frequently, until they are caramelized and golden brown.
3. Add Garlic: Stir in the minced garlic and cook for another 1–2 minutes, until fragrant.
4. Incorporate Broth: Pour in the vegetable or chicken broth. Add the dried thyme, salt, and pepper. Bring to a simmer.

6. Check for Doneness: Once the pasta is al dente, remove the pot from heat. If there’s excess liquid, let it simmer uncovered for a couple more minutes until it thickens slightly.
7. Melt Cheese: Stir in the Gruyère and Parmesan cheese until melted and creamy. Adjust seasoning with more salt and pepper as needed.
8. Serve: Ladle the pasta into bowls and garnish with freshly chopped parsley for a pop of color.
