Ingredients
- 400g pasta (linguine, fettuccine, or your favorite type)
- 4 large yellow onions, thinly sliced (substitute sweet onions if preferred)
- 3 tbsp butter (use vegan butter for dairy-free version)
- 2 tbsp olive oil
- 4 cups beef or vegetable broth (vegetable broth for vegan)
- 1/2 cup grated Gruyère cheese (swap with dairy-free cheese for dairy-free option)
- 1/4 cup grated Parmesan cheese
- 2 garlic cloves, minced
- 1 tsp fresh thyme leaves (or 1/2 tsp dried thyme)
- Salt and pepper, to taste
- Fresh parsley for garnish
Step-by-Step Instructions
- Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente. Drain and set aside, reserving a little pasta water.
- While pasta cooks, heat butter and olive oil in a large skillet over medium heat. Add sliced onions and stir frequently. Cook slowly until the onions are caramelized and golden brown, about 30 minutes.
- Add minced garlic and thyme to the onions; sauté for an additional 2 minutes until fragrant.
- Pour in the broth. Simmer the mixture, allowing the broth to reduce slightly and intensify in flavor, about 10 minutes.
- Add the cooked pasta to the skillet, tossing it well with the onion sauce. If needed, add a splash of reserved pasta water for creaminess.
- Sprinkle Gruyère and Parmesan cheese into the skillet. Stir until cheese is fully melted and the sauce becomes creamy and well combined.
- Season with salt and freshly ground pepper to taste. Garnish with fresh parsley before serving.

Expert Tips
To get the best caramelized onions, be patient and keep the heat medium to low to prevent burning. Stir often but allow them to brown gradually. If you want extra depth, add a splash of white wine or sherry during the broth simmer step. For a gluten-free version, use your favorite gluten-free pasta. To make ahead, prepare the onion base and broth sauce in advance; add pasta and cheese just before serving.
Storage
Store any leftover French Onion Pasta in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave, adding a splash of broth or water to restore creaminess. It can also be frozen for up to 1 month, though fresh pasta texture may slightly change upon thawing.
