- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 3 large yellow onions sliced thin
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1 tablespoon fresh thyme leaves or 1 teaspoon dried thyme
- 2 teaspoons balsamic vinegar
- 3 cloves garlic minced
- 4 cups low sodium beef broth or vegetable broth
- 8 ounces uncooked fettuccine or linguine
- 1/2 cup heavy cream
- 1 cup shredded Gruyère cheese
- 1/4 cup grated Parmesan cheese
- Chopped parsley for garnish
Heat the butter and olive oil in a large heavy-bottomed pot over medium heat. Add the sliced onions, salt, and pepper.
Cook the onions slowly for about 25 to 30 minutes, stirring often, until they are deep golden brown and caramelized. Reduce the heat if they begin to brown too quickly.
Stir in the thyme, balsamic vinegar, and garlic. Cook for 1 to 2 minutes until fragrant.
Pour in the broth and bring to a gentle boil.
Add the uncooked pasta directly into the pot. Simmer for 10 to 12 minutes, stirring frequently, until the pasta is al dente and most of the liquid has been absorbed.
Lower the heat and stir in the heavy cream, Gruyère, and Parmesan cheeses. Continue stirring until melted and the sauce is creamy.
Taste and adjust seasoning if needed. Serve hot, garnished with chopped parsley and extra Parmesan if desired.
