Ingredients You’ll Need
This recipe relies on straightforward, pantry-friendly ingredients that come together to create a spectacular balance of sweet, savory, and creamy flavors. Each one plays its part: from the caramelized onions that build the base, to the cheeses bringing luscious richness, and the herbs that brighten things up.
- Olive oil (3 tablespoons): Provides the perfect medium for slowly caramelizing the onions without burning.
- Unsalted butter (2 tablespoons): Adds a silky richness and depth of flavor to your onion base.
- Yellow onions (3 large, sliced into thin rings): The star of the dish, slow-cooked until naturally sweet and golden brown.
- Salt (1/8 tsp): Enhances the natural sweetness of the caramelized onions.
- Pepper (1/8 tsp + ½ tsp for seasoning): Brings a gentle heat and balance to the dish.
- Garlic cloves (4, minced): Adds aromatic depth and a subtle kick.
- Red pepper flakes (pinch to ¼ tsp): Gives a warm background heat that lingers pleasantly.
- Worcestershire sauce (1 tablespoon): Provides that unmistakable umami punch and mild tang.
- Reduced sodium soy sauce (1 tablespoon): Supplements umami without overpowering the onions.
- Water (5½ cups; or substitute beef broth): Creates the broth base; beef broth adds extra meaty richness.
- Evaporated milk (1 12 oz. can): Enriches the sauce, lending it a creamy texture without heaviness.
- Cornstarch (½ tablespoon): Helps thicken the sauce for a silky finish.
- Beef bouillon (2 tablespoons, granulated or base): Optional, for an extra boost of savory depth if not using broth.
- Fresh parsley (1 tablespoon minced or 1 tsp dried): Brightens the final dish with herbal freshness.
- Fresh thyme (2 teaspoons minced or ¾ tsp dried): Adds aromatic floral notes that complement the sweet onions.
- Dried oregano (½ tsp): Brings a subtle earthiness that rounds out the flavor profile.
- Paprika (½ tsp): Offers a mild smokiness and warmth.
- Short cut pasta (1 pound, such as orecchiette): Holds the sauce beautifully and adds a pleasing bite.
- Gruyere cheese (5 oz., freshly shredded): Melts beautifully into the sauce with its nutty, creamy flavor.
- Parmesan cheese (¼ cup freshly shredded): Provides sharpness and extra cheesy richness.
- Fresh parsley for garnish (optional): Adds a pop of color and fresh herbaceous aroma.
How to Make French Onion Pasta Recipe
Step 1: Caramelize the Onions
The magic starts with slowly cooking your thinly sliced yellow onions in a mix of butter and olive oil over medium heat. Patience is key here—the onions will need around 30 to 35 minutes to turn beautifully golden and caramelized, developing sweet, complex flavors that form the foundation of this dish. Make sure to stir occasionally so they brown evenly without burning.
Step 2: Build the Sauce
Once your onions have reached that perfect caramelized stage, it’s time to add minced garlic, red pepper flakes, Worcestershire sauce, and soy sauce into the pot. These ingredients inject layers of savory umami and a touch of spice. Pour in the water or beef broth along with your beef bouillon and spices like thyme, oregano, paprika, salt, and pepper. Bring this aromatic mixture to a gentle boil—this broth will become the heart of your French Onion Pasta Recipe.
Step 3: Cook the Pasta in the Broth
Instead of boiling pasta separately, add your dry short-cut pasta directly to the simmering sauce. This way, the pasta absorbs all the delicious flavors as it cooks, which should take about 20 to 25 minutes until perfectly al dente. Make sure to stir often to prevent the pasta from sticking and to evenly incorporate the sauce.
Step 4: Add the Cheeses
With the pasta tender and the broth thickened, remove the pot from heat and stir in freshly shredded Gruyere and Parmesan cheeses. These cheeses melt luxuriously into the sauce creating a rich, creamy coating over every bite. Taste and adjust seasoning with extra salt and pepper if needed, then sprinkle with minced fresh parsley for a final touch of brightness.
How to Serve French Onion Pasta Recipe
Garnishes
Simple garnishes make a huge difference here—a sprinkle of fresh parsley or chives adds color and freshness that lightens the luxurious flavors. You can also add extra Parmesan cheese for cheese lovers or a few crunchy toasted breadcrumbs for texture contrast.
Side Dishes
This pasta is a hearty, filling main that pairs wonderfully with crisp green salads, such as a tangy arugula salad with lemon vinaigrette. Roasted or steamed vegetables like asparagus, green beans, or a medley of root veggies complement the dish beautifully by adding freshness and crunch.
Creative Ways to Present
For a dinner party, serve individual portions in rustic shallow bowls and crown them with a sprig of thyme or freshly cracked pepper right before serving. Alternatively, bake the completed pasta briefly in the oven with extra cheese on top for a bubbling cheesy crust that’s irresistible.
Make Ahead and Storage
Storing Leftovers
Leftover French Onion Pasta Recipe is perfect for next-day meals. Store it in an airtight container in the refrigerator for up to 3 days. The flavors will deepen overnight, making it even tastier when reheated.
Freezing
You can freeze this dish, but for best results, freeze just the sauce and onions separately from the pasta. This helps maintain texture and avoids overly mushy pasta when thawed. Keep frozen for up to 2 months in freezer-safe containers.
Reheating
To reheat, gently warm in a saucepan over medium-low heat, adding a splash of water or broth to loosen the sauce if it’s thickened too much. Stir frequently until heated through. Avoid microwave reheating if possible to keep that smooth creamy texture.
FAQs
Can I use a different type of cheese?
Absolutely! While Gruyere and Parmesan are classic choices for the delicate nutty and sharp contrast, you can substitute with Emmental, Fontina, or even a mild cheddar depending on your taste preference. Just choose cheeses that melt well.
Is this recipe vegetarian?
The traditional recipe uses beef bouillon or broth which adds meaty depth, but you can easily make this vegetarian by using vegetable broth and omitting Worcestershire sauce or using a vegetarian version. The flavor will remain rich and satisfying.
What pasta shapes work best?
Short cut pastas like orecchiette, penne, or rigatoni work great because they hold the sauce well. Avoid very thin pastas like angel hair as they may overcook or get lost in the broth.
Can I make this gluten-free?
Yes! Simply swap out the regular pasta for a gluten-free variety of your choice. Just be sure to check that your broths and sauces are gluten-free as well to maintain flavor and safety.
How long can I caramelize the onions?
For maximum flavor, take your time caramelizing—30 to 35 minutes is ideal. If you cook them too fast over high heat, they may burn and turn bitter, so low and slow is key for that sweet, luscious base.

Ingredients
For the Onion Sauce
- 3 tablespoons olive oil
- 2 tablespoons unsalted butter
- 3 large yellow onions, sliced into 1/8-inch 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 beef broth and omit bouillon)
- 2 tablespoons beef bouillon (granulated, base, or cubes) (may omit if using beef broth)
- 1 12 oz. can evaporated milk
- 1/2 tablespoon cornstarch
- 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 Topping
- 1 pound short cut pasta (orecchiette recommended)
- 5 ounces freshly shredded Gruyere cheese
- 1/4 cup freshly shredded Parmesan cheese
- Fresh parsley for garnish (optional)
Instructions
- Caramelize Onions: Melt the butter in olive oil in a large Dutch oven over medium heat. Add the sliced onions, salt, and pepper. Cook, stirring occasionally, until the onions are deeply caramelized and golden brown, about 30 to 35 minutes, which builds the dish’s rich flavor base.
- Make Sauce: Stir in the minced garlic, red pepper flakes, soy sauce, and Worcestershire sauce to the caramelized onions. Add water (or beef broth), beef bouillon (if using water), evaporated milk, cornstarch, fresh herbs (parsley, thyme), dried oregano, paprika, and pepper. Bring the mixture to a rolling boil to meld all the flavors and create the savory sauce.
- Boil Pasta: Add the uncooked pasta directly into the boiling sauce and reduce the heat to a simmer. Cook, stirring often, for 20 to 25 minutes or until the pasta is al dente and has absorbed much of the flavorful broth.
- Add Cheeses: Remove the pot from heat. Stir in the shredded Gruyere and Parmesan cheeses until fully melted and incorporated, creating a creamy, cheesy finish. Taste and adjust seasoning with additional salt and pepper if needed. Garnish with fresh parsley if desired before serving.
Notes
- Mandaline slicing helps achieve uniformly thin onion rings for even caramelization.
- Using evaporated milk and cornstarch thickens the sauce while adding creaminess without heavy cream.
- The recipe can be made with beef broth instead of water and bouillon for richer flavor.
- Orecchiette or other small, short cut pasta works best to catch the sauce.
- Stir frequently when cooking pasta in sauce to prevent sticking and ensure even cooking.
- For a vegetarian version, omit Worcestershire sauce or use a vegetarian alternative and replace beef bouillon with vegetable bouillon.
