Ingredients

Scale

Main Ingredients

  • 3 tablespoons unsalted butter
  • 2 large onions, thinly sliced
  • 3 cloves garlic, minced
  • 1 teaspoon sugar
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 3 cups beef broth (or vegetable broth for vegetarian option)
  • 1 cup water
  • 12 ounces pasta (fettuccine, linguine, or spaghetti work well)
  • 1/2 cup heavy cream
  • 1 cup shredded Gruyère cheese (or Swiss cheese)
  • Fresh parsley, chopped (optional, for garnish)


Instructions

  1. Caramelize the Onions: In a large pot, melt the unsalted butter over medium heat. Add the thinly sliced onions and sugar, then cook for 15-20 minutes, stirring frequently, until the onions are golden brown and deeply caramelized.
  2. Add Garlic and Seasonings: Stir in the minced garlic, dried thyme, salt, and black pepper, cooking for an additional 1-2 minutes until fragrant.
  3. Add Liquid and Pasta: Pour in the beef broth and water, scraping the bottom of the pot to deglaze and release any browned bits. Add the pasta, making sure it is submerged in the liquid. Bring the mixture to a boil.
  4. Cook the Pasta: Reduce the heat to medium-low and simmer uncovered for 10-12 minutes. Stir occasionally to prevent sticking, cooking until the pasta is al dente and most of the liquid has been absorbed.
  5. Finish with Cream and Cheese: Stir in the heavy cream and shredded Gruyère cheese, mixing until the cheese is melted and the sauce becomes creamy. Adjust seasoning with additional salt and pepper to taste.
  6. Serve: Garnish the pasta with freshly chopped parsley if desired, and serve hot alongside crusty bread for a classic French onion inspired meal.

Notes

  • For a vegetarian option, substitute beef broth with vegetable broth.
  • Use Swiss cheese if Gruyère is unavailable; it provides a similar creamy melt and flavor.
  • Make sure to stir frequently while caramelizing the onions to prevent burning and ensure even cooking.
  • If the pasta absorbs the liquid too quickly before it’s fully cooked, add a splash more water or broth as needed.
  • Leftovers can be stored covered in the refrigerator for up to 3 days and reheated gently on the stovetop.
