Ingredients

Scale
  • 2 tablespoons butter
  • 3 large onions, thinly sliced
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 cloves garlic, minced
  • 1/2 cup dry white wine (optional)
  • 4 cups beef broth
  • 2 tablespoons Worcestershire sauce
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
  • 8 oz pasta (fusilli, penne, or rigatoni)
  • 1 cup heavy cream
  • 1 cup Gruyère cheese, grated
  • 1/2 cup Parmesan cheese, grated
  • Fresh thyme for garnish

Instructions

  1. Melt butter in a large skillet or Dutch oven over medium heat. Add onions and salt, cook for 20-25 minutes stirring occasionally until deeply caramelized and golden brown.
  2. Add minced garlic and cook for 1 minute until fragrant.
  3. If using white wine, pour into pan to deglaze, scraping up browned bits. Cook for 2-3 minutes until wine mostly evaporates.
  4. Add beef broth, Worcestershire sauce, and thyme. Stir well and bring to a simmer.
  5. Add uncooked pasta to skillet, stir to submerge. Cook according to package directions (10-12 minutes) stirring occasionally until al dente.
  6. Reduce heat to low and stir in heavy cream, Gruyère, and Parmesan. Stir continuously until cheese melts and sauce is creamy, about 2-3 minutes.
  7. Season with additional salt and pepper to taste.
  8. Garnish with fresh thyme before serving hot.

Notes

  • Patient caramelization develops deep flavor – don’t rush this step.
  • Swiss cheese substitutes well for Gruyère if needed.
  • For vegetarian version, use vegetable broth and omit or use vegetarian Worcestershire sauce.
  • Add splash of broth if sauce is too thick.
