3. Sauté the Mushrooms: Once the onions are caramelized, add the garlic, mushrooms, and thyme. Sauté until the mushrooms are soft, about 3-4 minutes.
4. Make the Sauce: Whisk in the flour, creating a thick paste. Slowly whisk in the white wine, all the flour paste should be incorporated smoothly.
5. Add Broth and Pasta: Add the beef broth, pasta, Worcestershire sauce, and salt and pepper. Bring to a low boil and cook until the pasta is al dente, or to the desired texture.
6. Serve: Remove the pot from heat and stir in the parmesan cheese. Serve fresh with additional parmesan cheese.
