Make a rich, cheesy pasta inspired by French Onion Soup using just one pot for simple cleanup.

Ingredients

Scale
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon salt, divided
  • 1/2 teaspoon black pepper, divided
  • 2 cloves garlic, minced
  • 1 tablespoon all-purpose flour
  • 4 cups beef broth
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon dried thyme
  • 12 ounces pasta (penne or rotini work well)
  • 1 cup shredded Gruyère cheese
  • 1/2 cup grated Parmesan cheese

Instructions

  1. Heat the olive oil in a large pot or Dutch oven over medium heat. Add the sliced onions and cook slowly, stirring occasionally, for 20 to 25 minutes until they are deeply browned and caramelized.
  2. Stir in 1/2 teaspoon of salt and 1/4 teaspoon of pepper during the last 5 minutes of caramelization.
  3. Add the minced garlic and cook for 1 minute until fragrant.
  4. Sprinkle the flour over the onions and stir constantly for 1 minute to cook out the raw flour taste.
  5. Pour in the beef broth, Worcestershire sauce, and thyme. Bring the mixture to a simmer, scraping up any browned bits from the bottom of the pot.
  6. Add the dry pasta to the simmering broth. Return to a gentle simmer, cover the pot, and cook for 12 to 15 minutes, or until the pasta is cooked through and most of the liquid is absorbed. Stir halfway through cooking to prevent sticking.
  7. Remove the pot from the heat. Stir in the remaining 1/2 teaspoon of salt and 1/4 teaspoon of pepper.
  8. Stir in the Gruyère cheese and Parmesan cheese until the sauce is smooth and creamy. Serve immediately.

Notes

  • For deeper flavor, use low-sodium beef broth and add 1 teaspoon of soy sauce with the Worcestershire sauce.
  • If the sauce becomes too thick while cooking, add a splash of hot water or extra broth until you reach your desired consistency.
  • You can substitute Swiss cheese for Gruyère if needed, but Gruyère provides the best authentic flavor.
