Ingredients
Method
Cook the Pasta
- In a large pot, bring salted water to a boil and cook the fettuccine according to package instructions until al dente. Drain and set aside.
Caramelize the Onions
- In a skillet, heat the butter and olive oil over medium heat. Add the sliced onions and cook, stirring frequently, for about 20-25 minutes until they are golden brown and caramelized.
Make the Sauce
- Add the beef broth to the skillet with the caramelized onions and bring to a simmer. Stir in the heavy cream, thyme, salt, and pepper, and let it cook for another 5 minutes.
Combine Pasta and Sauce
- Add the cooked fettuccine to the skillet and toss to combine, ensuring the pasta is well coated with the sauce.
Serve
- Serve the pasta hot, topped with shredded gruyère and grated parmesan cheese. Optionally, broil for a few minutes to melt the cheese on top.

Notes
For a vegetarian version, use vegetable broth instead of beef broth.
