Ingredients

For the Pasta
  • 12 oz fettuccine pasta or pasta of choice
  • 1 tbsp salt for pasta water
For the Caramelized Onions
  • 2 tbsp unsalted butter for richness
  • 2 tbsp olive oil to prevent butter from burning
  • 3 large yellow onions thinly sliced
  • 1 tbsp sugar to enhance caramelization
  • 1 tsp salt to draw out moisture
For the Sauce
  • 4 cups beef broth low-sodium recommended
  • 1 cup heavy cream for creaminess
  • 1 cup gruyère cheese shredded, for topping
  • 1 tsp thyme fresh or dried
  • 1 tsp black pepper freshly ground
  • 1 tbsp Worcestershire sauce for depth of flavor

Method

Cook the Pasta
  1. Bring a large pot of salted water to a boil. Add the fettuccine and cook according to package instructions until al dente, usually about 8-10 minutes.
  2. Reserve 1 cup of pasta water, then drain the pasta in a colander and set aside.
Caramelize the Onions
  1. In a large skillet, heat the butter and olive oil over medium heat. Once melted, add the sliced onions.
  2. Sprinkle the onions with sugar and salt. Stir occasionally to prevent sticking, and cook for about 20-25 minutes until the onions are golden brown and caramelized. This slow cooking will develop their natural sweetness.
Prepare the Sauce
  1. Once the onions are caramelized, add the beef broth to the skillet. Bring to a simmer and let it cook for about 5 minutes to meld the flavors.
  2. Stir in the heavy cream, thyme, Worcestershire sauce, and black pepper. Allow the sauce to simmer for an additional 5 minutes until slightly thickened.
Combine and Serve
  1. Add the drained pasta to the sauce, tossing to coat evenly. If the sauce is too thick, add reserved pasta water a little at a time until desired consistency is reached.
  2. Serve immediately, topped with shredded gruyère cheese. Optionally, broil for 2-3 minutes to melt and slightly brown the cheese for added flavor.
