Equipment

  • Large, deep skillet or Dutch oven
  • Cutting board
  • Knife
  • Measuring cups and spoons
  • Pasta pot
  • Colander
  • Bowls for serving

Ingredients
  

  • 1 pound pasta spaghetti, linguine, or fettuccine
  • 4 large yellow onions, thinly sliced
  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • 1 teaspoon sugar
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 4 cloves garlic, minced
  • ¼ cup dry sherry or dry white wine
  • 4 cups beef broth
  • 1 teaspoon dried thyme
  • 1 bay leaf
  • 1 cup grated Gruyère cheese
  • ¼ cup chopped fresh parsley, for garnish optional

Instructions
 

  • Heat olive oil and butter in a large, deep skillet or Dutch oven over medium heat.
  • Add sliced onions, sugar, salt, and pepper. Cook, stirring occasionally, for 30-45 minutes, or until the onions are deeply caramelized and a rich golden-brown color.
  • Add minced garlic to the caramelized onions and cook for another minute until fragrant.
  • Pour in the sherry (or white wine) and scrape up any browned bits from the bottom of the pan. Let it simmer for a minute or two to reduce slightly.
  • Pour in the beef broth, add thyme and bay leaf. Bring to a simmer and cook for 15 minutes, allowing the flavors to meld together.
  • While the sauce is simmering, cook pasta according to package directions until al dente. Reserve about 1 cup of pasta water before draining.
  • Add the drained pasta to the skillet with the onion sauce. Toss to coat evenly. If the sauce is too thick, add a little of the reserved pasta water to reach your desired consistency.
  • Remove from heat and stir in half of the Gruyère cheese.
  • Divide the pasta among bowls. Top with remaining Gruyère cheese and garnish with fresh parsley, if desired. For an extra touch, you can broil the pasta for a minute or two to melt and brown the cheese.

Notes

Caramelizing onions takes time; cook them over medium-low heat, stirring occasionally to prevent burning. Beef broth is traditional, but vegetable broth can be used for a vegetarian version. Gruyère can be substituted with Swiss, Fontina, or a mix of Parmesan and mozzarella. Store leftovers in the refrigerator for up to 3 days. To reheat, microwave or heat in a skillet with a little broth or water.
