Ingredients

Scale

Main Ingredients

  • 3 large yellow onions, sliced into rings 1/8-inch thick
  • 1 pound short cut pasta (orecchiette)
  • 5 ounces freshly shredded Gruyere cheese
  • ¼ cup freshly shredded Parmesan cheese

Cooking Fats and Liquids

  • 3 tablespoons olive oil
  • 2 tablespoons unsalted butter
  • 4 cups water
  • 1 12-ounce can evaporated milk
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon reduced sodium soy sauce

Seasonings and Herbs

  • 4 garlic cloves, minced
  • 2 tablespoons beef bouillon
  • 1 tablespoon fresh parsley, minced (or 1 teaspoon dried)
  • 2 teaspoons fresh thyme, minced (or ¾ teaspoon dried)
  • 1/8 teaspoon salt
  • 1/8 teaspoon pepper
  • ½ teaspoon dried oregano
  • ½ teaspoon paprika
  • ½ tablespoon cornstarch
  • 1 pinch to ¼ teaspoon red pepper flakes
  • Fresh parsley for garnish (optional)

Instructions

  1. Slice onions thinly and caramelize them in a large pot over medium-low heat, stirring occasionally until they turn a deep golden brown and develop a rich, sweet flavor, approximately 20-25 minutes.
  2. Introduce minced garlic, red pepper flakes, soy sauce, and Worcestershire sauce to the caramelized onions. Sauté the mixture for 30 seconds to release their aromatic flavors.
  3. Pour water and half of the evaporated milk into the pot. In a separate small bowl, whisk the cornstarch with the remaining evaporated milk until smooth and lump-free.
  4. Increase the heat to high and add the cornstarch mixture, beef bouillon, and remaining herbs and seasonings. Stir continuously to prevent scorching and ensure even distribution of flavors.
  5. Once the liquid reaches a rolling boil, add the pasta and reduce the heat to medium-high. Simmer uncovered for 11-14 minutes, stirring frequently to prevent sticking and ensure even cooking.
  6. Gently push the pasta into an even layer, making sure it’s fully submerged in the liquid. The pasta should remain slightly saucy when fully cooked.
  7. Remove the pot from heat and gradually incorporate Gruyere cheese, stirring until completely melted. Follow with Parmesan cheese, continuing to stir until smooth and integrated.
  8. Taste the pasta and adjust seasoning with salt and pepper as needed. If a more liquid consistency is desired, stir in additional water or milk.
  9. Optionally, garnish with freshly chopped parsley for a burst of color and fresh herb flavor before serving.

Notes

  • Caramelizing onions takes patience, developing deep, rich flavor that transforms this pasta dish from ordinary to extraordinary.
  • Stirring frequently prevents burning and ensures even cooking, creating a golden-brown base for the sauce.
  • Cornstarch acts as a thickening agent, helping to create a luxurious, creamy texture without separating the sauce.
  • Choosing the right pasta shape matters – use short, sturdy varieties like penne or rotini that hold sauce beautifully.
  • Gruyere and Parmesan cheeses deliver complex, nutty undertones that elevate the overall taste profile of the dish.
  • Adding fresh parsley at the end provides a bright, fresh contrast to the rich, deep flavors of the caramelized onions and cheeses.
