Ingredients

Scale
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon salt, divided
  • 2 cloves garlic, minced
  • 1 teaspoon dried thyme
  • 1/2 teaspoon black pepper
  • 1/4 cup dry sherry or dry white wine (optional)
  • 4 cups beef broth
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon soy sauce
  • 1 pound short-cut pasta (like 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 Dutch oven or deep pot over medium heat. Add the sliced onions and 1/2 teaspoon of salt. Cook slowly, stirring occasionally, for 20 to 25 minutes until the onions are deeply browned and caramelized. Reduce heat if they start to burn.
  2. Add the minced garlic, thyme, and pepper to the caramelized onions. Cook for 1 minute until fragrant.
  3. Pour in the sherry or wine, if using, and scrape up any browned bits from the bottom of the pot. Let it cook down for 2 minutes.
  4. Stir in the beef broth, Worcestershire sauce, and soy sauce. Bring the mixture to a boil.
  5. Add the dry pasta to the pot. Reduce the heat to medium-low, cover the pot, and simmer for 12 to 15 minutes, stirring every few minutes to prevent the pasta from sticking, until the pasta is tender and most of the liquid is absorbed.
  6. Remove the pot from the heat. Stir in the evaporated milk and the remaining 1/2 teaspoon of salt.
  7. Stir in the Gruyère cheese and Parmesan cheese until the sauce is smooth and creamy. Serve immediately with extra cheese on top if desired.

Notes

  • For the deepest flavor, take your time caramelizing the onions; this step is key to the French Onion Soup taste.
  • If you do not have beef broth, use vegetable broth, but add 1/2 teaspoon of onion powder for depth.
  • This recipe works best with short pasta shapes that hold the sauce well.
