Creating French Onion Soup Pasta is a delightful process. Follow these simple steps:

1. Cook Pasta: In a large pot, bring salted water to a boil. Cook the pasta according to package instructions until al dente. Drain and set aside.
2. Caramelize Onions: In a large skillet, heat the butter and olive oil over medium heat. Add the sliced onions and cook, stirring frequently, for about 30-40 minutes until they are deeply caramelized and golden brown.
3. Add Wine: If using, deglaze the skillet with white wine, scraping up any browned bits from the bottom. Let it simmer for about 5 minutes.
4. Add Broth: Pour in the beef broth, thyme, salt, and pepper. Bring the mixture to a simmer and let it cook for an additional 10-15 minutes to allow the flavors to deepen.
5. Combine Pasta: Add the cooked pasta to the skillet, stirring to combine everything well. Let it heat through for about 5 minutes.
6. Prepare for Cheese: Preheat your oven’s broiler. Transfer the pasta mixture to an oven-safe dish.
7. Add Cheese: Sprinkle the shredded Gruyère cheese evenly over the top of the pasta.
8. Broil: Place the dish under the broiler for about 5-10 minutes, or until the cheese is bubbly and golden brown.
9. Garnish: Remove from the oven and sprinkle with fresh parsley before serving.
