  • Total Time: 35 minutes
  • Yield: 4 servings

Ingredients

Base Ingredients

  • 2 tablespoons Salted Butter
  • 1 tablespoon Olive Oil
  • 2 Large Onions, thinly sliced
  • 4 Cloves Garlic, minced
  • ½ teaspoon Dried Thyme

Liquids & Sauces

  • 1 tablespoon Balsamic Vinegar
  • ¼ cup Dry White Wine
  • 1 tablespoon Worcestershire Sauce
  • 32 oz Beef Broth (about 4 cups)
  • ¼ cup Heavy Cream

Pasta & Cheese

  • ½ lb Rigatoni (uncooked)
  • 5.3 oz Le Gruyère® AOP, shredded

Instructions

  1. Caramelize Onions: Add the salted butter to a heavy-bottomed skillet or braiser over medium heat. Once melted, add the thinly sliced onions, olive oil, and a hefty pinch of salt. Cook for about 20 minutes, stirring often, until the onions are soft and beginning to brown.
  2. Sauté Garlic and Thyme: Add the minced garlic and dried thyme to the caramelized onions. Cook for an additional 3 minutes until the garlic is tender and fragrant, being careful not to burn the garlic.
  3. Deglaze the Pan: Pour in the balsamic vinegar and dry white wine to deglaze the pan, scraping up all the flavorful browned bits stuck to the bottom of the pan with a wooden spoon or spatula.
  4. Add Pasta and Broth: Add the uncooked rigatoni pasta, Worcestershire sauce, and beef broth to the pan. Stir well to combine, making sure the pasta is submerged in the liquid.
  5. Simmer Pasta: Cover the pan with a lid and cook over a medium simmer for about 20 minutes. Remove the lid occasionally to stir and prevent the noodles from sticking. The liquid should absorb into the pasta; if the sauce remains too watery after the pasta is al dente, leave the lid off and simmer a few more minutes until thickened.
  6. Add Cheese and Cream: Once the pasta is cooked through and the sauce has thickened, stir in the shredded Gruyère cheese and heavy cream gently until the sauce becomes creamy and smooth.
  7. Season and Serve: Taste the pasta and season with flaky salt and freshly ground black pepper as desired. Serve immediately while warm and creamy.

Notes

  • Using a heavy-bottomed skillet or braiser helps with even cooking and prevents burning during caramelization.
  • Patience is key when caramelizing the onions to develop deep flavor and sweetness.
  • Stir the pasta occasionally while simmering to avoid sticking and ensure even cooking.
  • If you prefer a vegetarian version, substitute beef broth with a rich vegetable broth.
  • Gruyère cheese adds authentic flavor, but you may substitute with Swiss cheese if needed.
