Ingredients

Scale

Main Ingredients:

  • 3 large yellow onions, thinly sliced
  • 12 ounces (340 grams) uncooked rigatoni or other short pasta
  • 5 cups (1.2 liters) low-sodium beef broth

Dairy and Cheese:

  • 2 tablespoons (30 grams) unsalted butter
  • 1 cup (100 grams) shredded Gruyere cheese
  • 1/4 cup (60 milliliters) heavy cream

Aromatics and Seasonings:

  • 2 tablespoons (30 milliliters) olive oil
  • 4 cloves garlic, minced
  • 1 tablespoon fresh thyme leaves
  • 1/4 cup (60 milliliters) dry white wine (optional)
  • 1 tablespoon Worcestershire sauce
  • Salt and freshly ground black pepper, to taste
  • Fresh parsley, chopped, for garnish

Instructions

  1. Warm a large pot over medium heat and gently melt butter, creating a smooth base for transforming raw onions into a rich, golden delicacy.
  2. Carefully layer sliced onions into the pot, stirring consistently to coax them into a deep, caramel-like transformation that develops complex, sweet undertones over 20-25 minutes.
  3. Deglaze the pot with a splash of broth, using a wooden spoon to lift those intensely flavored browned bits clinging to the bottom, releasing their concentrated essence.
  4. Pour remaining broth into the pot, allowing the liquid to reach a vigorous boil before introducing pasta, then immediately reduce heat to a gentle simmer.
  5. Let the pasta absorb the flavorful liquid, stirring occasionally to ensure even cooking and prevent sticking, until the pasta reaches perfect tenderness and most liquid disappears.
  6. Sprinkle shredded Gruyère over the pasta, folding gently to create a luxuriously creamy sauce that envelops each pasta strand with nutty, melted cheese.
  7. Season the dish with salt and pepper, tasting and adjusting to balance the robust flavors of caramelized onions and rich cheese.
  8. Transfer to serving dishes and garnish with fresh parsley or thyme, adding a vibrant, herbaceous note that cuts through the dish’s richness.

Notes

  • Slowly caramelize onions over medium-low heat to develop deep, rich flavor without burning, which requires patience and occasional stirring.
  • Choose a heavy-bottomed pot to ensure even heat distribution and prevent scorching during the caramelization process.
  • Replace Gruyère with plant-based cheese for a dairy-free version, or swap with vegan alternatives like nutritional yeast for a similar umami profile.
  • Enhance the dish’s protein content by adding cooked chicken, crispy pancetta, or plant-based protein like white beans for extra nutrition and texture.
