A savory pasta dish cooked in one pot with caramelized onions, rich broth, and melted cheese, capturing the flavors of French onion soup in a comforting, easy meal!
Sauté the Onions: In a large pot or skillet, heat the olive oil over medium heat. Add the sliced onions and sauté for about 10-12 minutes, stirring occasionally, until they are caramelized and golden brown.
Add Garlic: Stir in the minced garlic and cook for another minute until fragrant.
Combine Ingredients: Add the pasta to the pot, followed by the beef broth, balsamic vinegar, thyme, salt, and pepper. Stir to combine.
Cook the Pasta: Bring the mixture to a boil, then reduce the heat to low. Cover and simmer for about 10-12 minutes, or until the pasta is cooked al dente and the liquid has mostly absorbed.
Add Cheese: Once the pasta is cooked, remove the pot from the heat. Stir in the shredded Gruyère and grated Parmesan cheese until melted and creamy.
Serve: Garnish with fresh parsley if desired and serve warm.
