Transform the rich, comforting flavors of French onion soup into an easy, creamy pasta dish made entirely in one pot for minimal cleanup. This recipe features deeply caramelized onions and savory Gruyère cheese, making it an ideal weeknight dinner.

Ingredients

Scale
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 2 cloves garlic, minced
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 4 cups beef broth
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon soy sauce
  • 1 pound short pasta, such as penne or rotini
  • 1/2 cup evaporated milk
  • 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 caramelized and sweet. This step builds the flavor foundation.
  2. Add the minced garlic, thyme, salt, and pepper to the pot. Cook for 1 minute until fragrant.
  3. Pour in the beef broth, Worcestershire sauce, and soy sauce. Bring the mixture to a simmer.
  4. Add the dry pasta to the pot. Stir well to combine. Continue to simmer, stirring often to prevent sticking, until the pasta is cooked through and most of the liquid is absorbed, about 10 to 12 minutes.
  5. Reduce the heat to low. Stir in the evaporated milk until the sauce is smooth and creamy. Do not let it boil after adding the milk.
  6. Remove the pot from the heat. Stir in the Gruyère cheese and Parmesan cheese until they are fully melted and the sauce is luscious.
  7. Serve immediately in bowls.

Notes

  • For an even richer flavor, use high-quality beef bouillon or stock.
  • If you prefer a thicker sauce, let the pasta sit off the heat for 5 minutes before stirring in the cheese.
  • This recipe pairs well with a light Pinot Noir or a dry Rosé.
