Ingredients You’ll Need
These ingredients come together so simply, yet each one plays an essential role in building the layers of flavor and texture that make this French Onion Pasta Recipe unforgettable. From the sweetness of caramelized onions to the creamy tang of evaporated milk and the earthy punch of herbs, every component matters.
- Olive oil (3 tablespoons): Provides the perfect base for sautéing and adds a subtle fruity richness.
- Unsalted butter (2 tablespoons): Helps caramelize the onions beautifully and enhances the sauce’s creaminess.
- Yellow onions, sliced (3 large): The star ingredient, sliced thin for maximum caramelization and sweetness.
- Salt and pepper (1/8 tsp each): Essential seasonings to balance and highlight flavors.
- Garlic cloves, minced (4): Adds a fragrant kick that complements the onions perfectly.
- Red pepper flakes (pinch to 1/4 tsp): Gives a gentle heat that wakes up the palate.
- Worcestershire sauce (1 tablespoon): Adds a deep umami note that intensifies the savoriness.
- Reduced sodium soy sauce (1 tablespoon): Works with Worcestershire to deepen the sauce’s complexity.
- Water or beef broth (5 1/2 cups): Creates the flavorful base for the pasta to cook in and the sauce to develop.
- Evaporated milk (1 12 oz. can): Brings creaminess without overpowering the dish.
- Cornstarch (1/2 tablespoon): Thickens the sauce to a luscious, clingy consistency.
- Beef bouillon (2 tablespoons): Optional, but adds rich depth if you’re using water instead of broth.
- Fresh parsley, minced (1 tablespoon): For lively herbaceousness; dried can be a fallback.
- Fresh thyme, minced (2 teaspoons): Offers an earthy, slightly minty aroma that’s classic in French onion dishes.
- Dried oregano (1/2 teaspoon): Adds subtle warmth and complexity.
- Paprika (1/2 teaspoon): Brings a mild smoky sweetness and beautiful color.
- Additional pepper (1/2 teaspoon): Balances the richness with a bit of bite.
- Pasta (1 pound): Short cut shapes like orecchiette are perfect for catching all the sauce.

- Parmesan cheese, shredded (1/4 cup): Adds sharpness and depth to the final dish.
- Fresh parsley (for garnish, optional): A pop of color and fresh flavor to finish.
How to Make French Onion Pasta Recipe
Step 1: Caramelize the Onions
Start by melting butter into olive oil in a large Dutch oven over medium heat. Add the sliced onions along with salt and pepper and let them slowly cook down. Patience is key here—the onions should cook for about 30 to 35 minutes until they turn deep golden brown and develop that signature sweet, rich flavor. Stir occasionally to avoid burning and to ensure even caramelization. This step forms the flavor foundation of the entire dish.
Step 2: Build the Sauce
Once your onions are perfectly caramelized, add the minced garlic and red pepper flakes, letting the aromas fill your kitchen. Then stir in Worcestershire sauce and soy sauce to deepen the umami notes. Pour in the water (or beef broth if you prefer) along with evaporated milk, bouillon, and cornstarch to thicken. Add your fresh and dried herbs—parsley, thyme, oregano—as well as paprika and additional pepper. Bring everything to a boil, watching as the flavors meld into a rich, silky sauce that will coat your pasta fabulously.
Step 3: Cook the Pasta in the Sauce
Add the uncooked pasta directly to the boiling sauce and reduce to a simmer. Cook for 20 to 25 minutes, stirring often to prevent sticking, until the pasta is perfectly al dente. Cooking pasta in the sauce itself absorbs all those wonderful flavors—this is what elevates the French Onion Pasta Recipe beyond ordinary pasta dishes.
Step 4: Add the Cheeses
Remove the pot from heat and immediately stir in the shredded Gruyere and Parmesan cheeses until melted and luxuriously melted into the sauce. Taste and adjust salt and pepper as needed. The cheese adds a creamy finish with just the right touch of nuttiness that melds everything together beautifully.
How to Serve French Onion Pasta Recipe
Garnishes
A sprinkle of freshly chopped parsley on top adds a fresh, vibrant color and flavor that brightens the dish. If you’re feeling fancy, a few extra shavings of Parmesan or a drizzle of good olive oil can make this feel extra special.
Side Dishes
This dish is quite hearty on its own, but it pairs wonderfully with crisp green salads or roasted vegetables to add lightness and crunch. Warm crusty bread is perfect for mopping up any leftover sauce—you definitely don’t want to waste a drop!
Creative Ways to Present
For a rustic touch, serve it straight from the Dutch oven family-style. Or try plating individual portions in shallow bowls and topping with a little extra cheese and a fresh herb sprig for a restaurant-worthy presentation. This pasta is also fantastic baked briefly with extra cheese on top for a gratin-like finish.
Make Ahead and Storage
Storing Leftovers
Leftover French Onion Pasta Recipe stores beautifully in an airtight container in the refrigerator for up to 3 days. The flavors actually continue to meld, making for an even tastier meal the next day.
Freezing
You can freeze this pasta, though cheese-based sauces sometimes separate slightly upon thawing. Store in a freezer-safe container for up to 1 month. Thaw overnight in the fridge before reheating gently on the stove.
Reheating
Reheat on the stove over low-medium heat with a splash of water or broth to loosen the sauce and prevent drying or sticking. Stir gently until warmed through and creamy again—avoid high heat to keep the cheese smooth and avoid clumping.
FAQs
Can I use other types of onions for the French Onion Pasta Recipe?
Yellow onions are preferred for their natural sweetness and caramelizing qualities, but white onions can work in a pinch. Avoid red onions as they have a different flavor profile and color.
Is evaporated milk necessary or can I substitute it?
Evaporated milk adds creaminess without overpowering the dish. You can substitute with half-and-half or a mixture of milk and cream, but whole milk alone won’t yield quite the same velvety texture.
What pasta shapes work best for this recipe?
Short cut pasta like orecchiette or shells are ideal since they catch and hold the sauce well. Penne or rigatoni are also good options. Avoid long strands like spaghetti that don’t cling as well.
Can I make this recipe vegetarian?
Yes! Substituting vegetable broth for beef broth and omitting the Worcestershire sauce (or using a vegan version) will make it vegetarian-friendly without sacrificing flavor.
How spicy is the finished dish?
The red pepper flakes add just a gentle warmth that enhances the savory flavors without overwhelming. You can adjust the amount to suit your preferred spice level, or omit entirely for a milder dish.

Ingredients
For the Onion Sauce
- 3 tablespoons olive oil
- 2 tablespoons unsalted butter
- 3 large yellow onions, sliced into 1/8-inch thick rings (Mandoline recommended)
- 1/8 teaspoon salt
- 1/8 teaspoon pepper
- 4 garlic cloves, minced
- Pinch to 1/4 teaspoon red pepper flakes
- 1 tablespoon Worcestershire sauce
- 1 tablespoon reduced sodium soy sauce
- 5 1/2 cups water (may substitute with beef broth and omit bouillon)
- 1 12-ounce can evaporated milk
- 1/2 tablespoon cornstarch
- 2 tablespoons beef bouillon (granulated, base or cubes) (may omit if using beef broth)
- 1 tablespoon fresh parsley, minced (or 1 teaspoon dried)
- 2 teaspoons fresh thyme, minced (or 3/4 teaspoon dried)
- 1/2 teaspoon dried oregano
- 1/2 teaspoon paprika
- 1/2 teaspoon pepper
For the Pasta and Cheese
- 1 pound short cut pasta (such as orecchiette), uncooked
- 5 ounces freshly shredded Gruyere cheese
- 1/4 cup freshly shredded Parmesan cheese
- Fresh parsley, for garnish (optional)
Instructions
- Caramelize onions: Melt the butter into olive oil in a large Dutch oven over medium heat. Add the sliced onions along with salt and pepper. Cook slowly, stirring occasionally, until the onions become deeply caramelized and golden brown, approximately 30 to 35 minutes. This slow cooking develops the rich, sweet flavor essential to the sauce.
- Make the sauce: Add minced garlic, red pepper flakes, Worcestershire sauce, and soy sauce to the caramelized onions. Stir to combine. Then add water (or beef broth), evaporated milk, beef bouillon (if using), cornstarch, and all the herbs and spices: parsley, thyme, oregano, paprika, and pepper. Increase heat and bring the mixture to a boil, stirring frequently to dissolve the bouillon and thicken the sauce.
- Add and cook pasta: Once the sauce is boiling, add the uncooked pasta directly into the pot. Reduce heat to a simmer and cook uncovered, stirring often to prevent sticking, until the pasta is al dente—about 20 to 25 minutes. The pasta absorbs the flavorful sauce while cooking, creating a creamy one-pot dish.
- Add cheeses and finish: Remove the pot from heat. Immediately stir in the shredded Gruyere and Parmesan cheeses until fully melted and incorporated into the sauce. Taste and adjust seasoning with salt and pepper if needed. Garnish generously with fresh parsley if desired, and serve hot.
Notes
- Using a mandoline for slicing onions ensures even thickness and consistent caramelization.
- If you prefer a dairy-free version, you can omit evaporated milk and use a plant-based alternative, but the creaminess may be reduced.
- Be sure to stir frequently when cooking pasta in the sauce to prevent it from sticking to the bottom of the pot.
- Substitute beef broth for water and omit the beef bouillon for a more robust onion soup flavor.
- Fresh herbs add brightness but dried herbs work well if fresh are unavailable.
- Gruyere cheese adds a nutty, melty texture; subbing with other melting cheeses like fontina is possible but will alter flavor.
