Ingredients List
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 4 large yellow onions, thinly sliced
- 4 cloves garlic, minced
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried)
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 tablespoon all-purpose flour
- 4 cups beef or vegetable broth
- 1 cup dry white wine (optional, for depth)
- 12 ounces pasta (penne, fusilli, or spaghetti)
- 1 cup shredded Gruyère cheese
- ½ cup grated Parmesan cheese
- Fresh parsley, chopped, for garnish
Step-by-Step Instructions
Step 1: Caramelize the Onions
In a large pot or deep skillet, heat butter and olive oil over medium heat. Add sliced onions and salt. Cook, stirring occasionally, until onions are deeply golden and caramelized, about 30–35 minutes.
Step 2: Add Garlic and Thyme
Stir in garlic and thyme, cooking for 1–2 minutes until fragrant.
Step 3: Build the Base
Sprinkle flour over the onions and stir to combine. Cook for 1 minute to remove the raw flour taste.
Step 4: Deglaze and Simmer
Pour in wine (if using), scraping up browned bits from the pot. Add broth and bring to a simmer.
Step 5: Cook the Pasta
Add pasta directly to the pot. Stir occasionally and cook until the pasta is al dente and most of the liquid is absorbed, about 10–12 minutes depending on the pasta type.
Step 6: Finish with Cheese
Remove from heat. Stir in Gruyère and Parmesan until creamy and melted. Adjust salt and pepper to taste.
Step 7: Serve
Plate the pasta and garnish with fresh parsley. Serve immediately with extra cheese on the side if desired.

FAQs
Q1: Can I make this pasta vegetarian?
Yes! Use vegetable broth instead of beef broth and ensure any added proteins are plant-based. The caramelized onions provide rich flavor without meat.
Q2: Can I prepare the onions ahead of time?
Absolutely. Caramelize the onions up to 2 days in advance and refrigerate. Reheat before finishing the pasta for faster weeknight preparation.
Q3: What type of pasta works best?
Short pasta like penne or fusilli holds the sauce well, but spaghetti or linguine can also be used. Cooking time may vary slightly depending on pasta type.
