Ingredients of Easy French Onion Pasta
- 8 oz pasta (e.g., spaghetti or fettuccine)
- 2 large onions, thinly sliced
- 3 tablespoons butter
- 2 cloves garlic, minced
- 2 cups beef or vegetable broth
- 1 teaspoon thyme
- Salt and pepper to taste
- 1 cup grated Gruyère cheese

Step-by-Step Instructions of Easy French Onion Pasta
- Bring a large pot of salted water to a boil and cook the pasta according to package directions until al dente. Drain and set aside.
- Melt butter in a large skillet over medium heat. Add the thinly sliced onions and cook, stirring often, until they are deep golden brown and caramelized (about 12–15 minutes).

- Pour in the broth, scraping up any browned bits from the pan. Bring to a simmer and let it reduce slightly for 3–5 minutes. Season with salt and pepper.

Tips for Success
- Don’t rush the onions slow caramelizing gives the best sweet, deep flavor.
- Use good-quality broth for richer taste; beef broth gives a more classic French onion note.
- Grate the Gruyère fresh for the best melt and taste.
- Save a little pasta water to loosen the sauce if it gets too thick.
Substitutions & Variations of Easy French Onion Pasta
To Make It Vegan/Gluten-Free:
- Use gluten-free pasta; swap butter for vegan buttery spread or olive oil; replace Gruyère with a vegan melting cheese or nutritional yeast for a cheesy flavor. Use vegetable broth to keep it vegan.
Variations:
- Add sliced mushrooms with the onions for extra umami.
- Stir in a splash of white wine with the broth for depth.
- Top with crispy bacon or pancetta for a smoky twist.
- Toss in cooked shredded chicken for more protein.
Storage Instructions of Easy French Onion Pasta
Refrigerator:
- Store leftovers in an airtight container for up to 3–4 days. Reheat gently on the stove with a splash of broth or water to loosen the sauce.
Freezer:
- This pasta is best fresh; cheese sauces can separate when frozen. If you must freeze, keep sauce and pasta separate in freezer-safe containers for up to 1 month and thaw in the fridge before reheating.
Make-Ahead:
- Caramelize the onions a day ahead and store in the fridge. Cook pasta just before serving and combine for the freshest texture.
Frequently Asked Questions (FAQ) of Easy French Onion Pasta
Can I use yellow or white onions instead of sweet onions?
Yes. Yellow or white onions work fine just cook a bit longer if they’re not as sweet to develop caramelization.
Can I skip the Gruyère?
You can substitute with Swiss or fontina for similar meltiness. For a lighter version, reduce the cheese amount.
Will the dish be too salty with beef broth and cheese?
Taste the broth before adding salt. Use low-sodium broth if you’re worried, and adjust salt after combining the pasta and sauce.
