How to make One Pot French Onion Pasta

Ingredients:

  • 3 Yellow Onions (thinly sliced)
  • 3 Tablespoons Butter
  • 2 Tablespoons Extra Virgin Olive Oil
  • 4 Garlic Cloves (minced)
  • 1/4 cup White Wine (OPTIONAL)
  • 1 teaspoon Fresh Thyme (or 1/2 teaspoon dried thyme)
  • 1 teaspoon Black Pepper
  • 4 cups Beef Broth
  • 12 ounces Pasta (of choice)
  • 3/4 cup Heavy Cream (or half-n-half)
  • 6 ounces Gruyere Cheese (shredded)
  • 2 ounces Parmesan Cheese (shredded)
  • 1/2 to 1 teaspoon Worcestershire Sauce (OPTIONAL)

Directions:

  1. Heat butter and olive oil in a large skillet or Dutch oven over medium-low heat.
  2. Add the sliced onions with a pinch of salt. Stir to coat in the butter/oil.
  3. Cook slowly for 25-30 minutes, stirring occasionally, until the onions are deeply golden and caramelized and soft.

  5. Pour in the white wine (if using) and scrape up the browned bits from the bottom of the pan.
    • Cook until the wine has mostly evaporated. If you aren’t using white wine, add the beef broth at this step.
  6. Stir in the beef broth and simmer for 5 minutes.
  7. Add pasta and cook until perfectly al dente, according to package instructions.
    • Taste the pasta to make sure it is done cooking.
  8. Lower heat, add the cream, and stir until the sauce is silky.
