Ingredients

Scale
  • 2 tablespoonsbutter
  • 2 tablespoonsolive oil
  • 3large onions, thinly sliced
  • 3cloves garlic, minced
  • 1 teaspoonsugar
  • Salt and pepper, to taste
  • 1 teaspoonthyme (fresh or dried)
  • 8ouncespasta (fettuccine, linguine, or spaghetti)
  • 3cupsbeef broth (or vegetable broth for a vegetarian option)
  • 1cupwater
  • 1cupshredded Gruyère cheese (or mozzarella)
  • 1/2cupgrated Parmesan cheese
  • 2 tablespoonschopped fresh parsley, for garnish

Instructions

  1. Caramelize the onions: In a large pot or Dutch oven, heat the butter and olive oil over medium heat. Add the sliced onions, sugar, salt, and pepper. Cook, stirring occasionally, for 20-25 minutes, or until the onions are deeply caramelized and golden brown. Add the garlic and thyme, and cook for an additional 1-2 minutes.
  2. Add the pasta and liquids: Stir in the uncooked pasta, beef broth, and water. Bring to a boil, then reduce the heat to a simmer. Cook for 10-12 minutes, stirring occasionally, until the pasta is tender and most of the liquid is absorbed.
  3. Stir in the cheese: Once the pasta is cooked, stir in the Gruyère and Parmesan cheeses until melted and creamy.
  4. Garnish and serve: Sprinkle with fresh parsley before serving. Enjoy warm.

Notes

For extra depth of flavor, deglaze the pot with ¼ cup dry white wine before adding the pasta and broth.
Use vegetable broth for a vegetarian-friendly version.
Add extra cheese on top and broil for a few minutes for a crispy, cheesy finish.
