Ingredients
Scale
Base Ingredients
- 2 tablespoons butter
- 2 large yellow onions, thinly sliced
- 3 cloves garlic, minced
- 1 teaspoon fresh thyme (or 1/2 tsp dried)
- 1 tablespoon balsamic vinegar
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Pasta & Liquids
- 8 oz (about 225g) pasta (like fettuccine or linguine)
- 3 cups beef broth (or vegetable broth for vegetarian)
- 1/2 cup heavy cream
Cheese & Garnish
- 1/2 cup grated Gruyère or Swiss cheese (plus extra for topping)
- Fresh parsley, for garnish (optional)
Instructions
- Caramelize the Onions: In a large pot, melt the butter over medium heat. Add the thinly sliced onions and cook slowly for 20–25 minutes, stirring often, until the onions become deeply golden and caramelized, developing a sweet, rich flavor.
- Add Aromatics and Deglaze: Stir in the minced garlic, fresh thyme, salt, and black pepper. Cook for 1 minute to release the garlic’s aroma. Pour in the balsamic vinegar to deglaze the pot, scraping up any flavorful browned bits stuck to the bottom.
- Cook the Pasta in Broth: Add the uncooked pasta and pour in the beef broth. Bring the mixture to a boil, then reduce the heat to a simmer. Cook uncovered for 10–12 minutes, stirring occasionally, until the pasta is tender and most of the liquid has been absorbed.
- Finish with Cream and Cheese: Stir in the heavy cream and grated Gruyère cheese. Continue cooking for 1–2 more minutes until the sauce is creamy and the cheese has melted into the pasta.
- Serve and Garnish: Spoon the pasta into bowls, top with additional cheese if desired, and garnish with fresh parsley for a pop of color and freshness.
Notes
- You can substitute beef broth with vegetable broth to keep the dish vegetarian friendly.
- Use dried thyme if fresh is not available; its flavor is slightly more concentrated.
- Keep stirring occasionally during caramelization to prevent burning and help develop sweetness.
- Gruyère can be replaced with Swiss cheese or any good melting cheese like Fontina.
- For an extra depth of flavor, add a splash of white wine when deglazing if desired.
