This French Onion Pasta transforms the comforting flavors of French onion soup into a satisfying pasta dish. With caramelized onions, a rich broth, and nutty Gruyère cheese, it's a simple yet delicious meal that will become a new family favorite.
Caramelizing onions takes time; cook them over medium-low heat, stirring occasionally to prevent burning. Beef broth is traditional, but vegetable broth can be used for a vegetarian version. Gruyère can be substituted with Swiss, Fontina, or a mix of Parmesan and mozzarella. Store leftovers in the refrigerator for up to 3 days. To reheat, microwave or heat in a skillet with a little broth or water.
