How to Make French Onion Pasta

Not only is French onion pasta easy to make, but it all cooks in one pot for a fuss-free meal! It tastes so incredible too! It is going to be a huge hit with your whole family!

1. Prep: Cut the onions in half and then thinly slice them. Heat the butter in a large pot over medium-high heat and add the sliced onions.
2. Caramelize Onions: Cook the onions, stirring occasionally until the onions are caramelized, about 20-30 minutes.
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, so it creates 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. Then serve fresh with additional parmesan cheese.
