Ingredients

• 12 oz pasta (penne, rigatoni, or fettuccine work great)

• 2 tablespoons butter

• 3 large onions, thinly sliced

• 2 cloves garlic, minced

• 1 cup beef broth (or vegetable broth for a lighter version)

• 1 cup heavy cream (or half-and-half for a lighter version)

• 1 cup grated Gruyère cheese (or Swiss cheese)

• ½ cup grated Parmesan cheese

• 1 teaspoon dried thyme

• Salt and pepper, to taste

• Fresh parsley, chopped (for garnish)

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

1. Cook the pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Drain the pasta and set aside.

2. Caramelize the onions: While the pasta cooks, melt the butter in a large skillet or sauté pan over medium heat. Add the sliced onions and cook for 15-20 minutes, stirring occasionally, until the onions become golden brown and caramelized. This step builds the rich, sweet flavor of the onions, so be patient!

3. Sauté the garlic: Once the onions are caramelized, add the minced garlic to the skillet and cook for another 1-2 minutes until fragrant.

4. Add the broth and cream: Stir in the beef broth and heavy cream, scraping up any bits from the bottom of the pan. Bring the mixture to a simmer, then cook for 5-7 minutes, allowing the sauce to thicken slightly.

5. Add the cheese: Stir in the Gruyère cheese and Parmesan cheese, allowing them to melt and make the sauce creamy. Taste and adjust the seasoning with salt, pepper, and thyme.

6. Combine the pasta: Add the cooked pasta to the skillet with the onion sauce, tossing to coat the pasta evenly in the creamy, cheesy sauce. If the sauce seems too thick, add a bit more broth or cream to loosen it up.

7. Serve: Garnish with fresh parsley and an extra sprinkle of Parmesan cheese. Serve immediately.

Variations

Storage/Reheating

• Storage: Store leftovers in an airtight container in the fridge for up to 3 days.

• Reheating: To reheat, warm the pasta in a skillet over low heat, adding a splash of broth or cream to loosen the sauce. You can also microwave individual servings for 1-2 minutes, stirring halfway through.

FAQs

Can I use a different type of pasta?

Yes, you can use any pasta you prefer. Penne, fusilli, or rigatoni work great with this sauce. Just be sure to adjust the cooking time for the type of pasta you choose.

Can I make this dish ahead of time?

While French Onion Pasta is best enjoyed fresh, you can caramelize the onions and make the sauce ahead of time. Store the sauce and onions separately and combine them with the cooked pasta when ready to serve.

Can I use a different type of cheese?

Absolutely! Gruyère is traditional for its nutty, melty texture, but you can substitute with Swiss cheese, fontina, or even a sharp cheddar for a different flavor.

Can I make this dairy-free?

To make the dish dairy-free, use a dairy-free cream alternative like coconut cream or cashew cream and skip the cheese or use a plant-based cheese alternative.

How do I know when the onions are caramelized?

Caramelizing onions takes time—about 15-20 minutes. The onions will turn golden brown and develop a sweet, rich flavor. Be sure to stir occasionally to prevent burning.

Can I freeze French Onion Pasta?

This dish doesn’t freeze well due to the creamy sauce, but you can freeze the caramelized onions and sauce for up to 1-2 months. When you’re ready to eat, reheat the sauce, cook fresh pasta, and combine them together.
