Ingredients You’ll Need
This recipe embraces simplicity with ingredients that play essential roles—each adding layers of flavor, texture, and color to build that irresistible French Onion Pasta magic.
- Olive oil (3 tablespoons): A fruity base to gently melt the onions to caramelized perfection.
- Unsalted butter (2 tablespoons): Adds richness and helps brown the onions evenly without burning.
- Yellow onions (3 large, sliced): The star of the dish, sliced thin to develop a deep, golden caramelized flavor and soft texture.
- Salt and pepper (1/8 teaspoon each): To season the onions early and enhance all other flavors gently.
- Garlic (4 cloves, minced): A savory pop of aromatic flavor that awakens the sauce.
- Red pepper flakes (pinch to 1/4 teaspoon): Adds just the slightest kick without overpowering the dish.
- Worcestershire sauce (1 tablespoon): Brings an umami depth that mimics the richness of classic French onion broth.
- Reduced sodium soy sauce (1 tablespoon): Balances the sweetness with a subtle savory saltiness.
- Water (5 1/2 cups): The base for the broth; you can swap for beef broth if preferred for more meaty flavor.
- Evaporated milk (1 can, 12 oz.): Provides creamy silkiness without heaviness, making the sauce luscious.
- Cornstarch (1/2 tablespoon): Thickens the sauce to coat the pasta beautifully.
- Beef bouillon (2 tablespoons, granulated or cubes): Optional, but intensifies that savory backbone in the broth.
- Fresh parsley (1 tablespoon, minced): Adds a lively herbal brightness to balance flavors.
- Fresh thyme (2 teaspoons, minced): Earthy and fragrant, a classic herb for French onion dishes.
- Dried oregano, paprika, pepper (1/2 teaspoon each): A delicate trio that layers subtle warmth and complexity.
- Short cut pasta (1 pound, uncooked): Orecchiette works wonderfully here, but any small shape that holds sauce well is welcome.
- Gruyere cheese (5 oz., freshly shredded): The creamy, nutty cheese that melts into the sauce in rich waves.
- Parmesan cheese (1/4 cup, freshly shredded): Sprinkles a sharp, salty finish to complement the Gruyere.
- Fresh parsley (for garnish): Optional but recommended to brighten the final presentation.
How to Make French Onion Pasta Recipe
Step 1: Caramelize the Onions
Start by melting the butter into the olive oil in a large Dutch oven over medium heat. Then add your thinly sliced yellow onions, seasoning with a pinch of salt and pepper. The key to this step is patience; stir occasionally and let the onions slowly soften and turn a deep golden brown over about 30 to 35 minutes. This process unlocks their natural sweetness and builds that signature flavor foundation you’ll love. If the onions start to stick or brown too fast, just reduce the heat or add a bit more butter or oil to keep them tender and perfect.
Step 2: Infuse the Aromatics and Sauces
Once your onions are caramelized to perfection, lower the heat and add the minced garlic, red pepper flakes, soy sauce, and Worcestershire sauce. Let these cook together for about 30 seconds to release their fragrant, savory notes that make this French Onion Pasta Recipe so irresistible.
Step 3: Build the Broth and Add Pasta
Pour in the water and half of the evaporated milk. In a separate small bowl, whisk the cornstarch with the remaining evaporated milk until smooth, then stir it into the pot. Bring the mixture to a boil on high heat, stirring in the beef bouillon along with all the herbs and spices. Once boiling, add your pasta. Reduce the heat to a medium-high simmer, cooking uncovered and stirring frequently. This usually takes about 20 to 25 minutes until the pasta is al dente and the liquid has thickened into a deliciously silky sauce. Be sure to push the pasta down to keep it submerged, adding a splash of water if the sauce thickens too much.
Step 4: Finish with Cheese
Remove the pot from heat and stir in the shredded Gruyere gradually so it melts evenly into the sauce. Follow with the Parmesan cheese, mixing until fully combined and creamy. At this point, taste and adjust with salt and pepper if you need a little extra seasoning. If you like your pasta saucier, add a bit more water or milk to loosen the sauce to your preference.

Creative Ways to Present
For an impressive dinner party look, serve this pasta in shallow bowls with a sprinkle of fresh herbs and an extra grating of Parmesan cheese.

Rustic wooden boards and natural linen napkins make perfect complements to this warm, cozy dish.
Make Ahead and Storage
Storing Leftovers
This pasta keeps well in an airtight container in the refrigerator for up to 3 days. Because it’s so saucy, the pasta will soak up flavors overnight and taste even better the next day. Just be sure to stir well before reheating.
Freezing
If you want to freeze leftovers, portion the pasta into freezer-safe containers, leaving some room for expansion. Freeze for up to 2 months. Keep in mind that the texture of the pasta may soften a little after freezing, but the flavor remains delicious.
Reheating
To reheat, gently warm the pasta in a skillet over medium-low heat with a splash of water or milk to revive the sauce’s creaminess. Stir frequently to prevent sticking and heat evenly. Avoid microwaving if possible, as slow reheating preserves the flavors and texture best.
FAQs
Can I use a different type of pasta for this French Onion Pasta Recipe?
Absolutely! While orecchiette works beautifully because it holds sauce well, feel free to use penne, rigatoni, or even fusilli—any pasta that catches the sauce will be delicious.
Can I make this recipe vegetarian?
Yes! Skip the beef bouillon and replace the water with vegetable broth. The soy sauce and Worcestershire sauce add wonderful umami notes that keep the flavor rich and satisfying.
How long does it take to caramelize the onions?
Caramelizing onions for this recipe takes about 30 to 35 minutes over medium heat. Patience is key here because this slow cooking process creates that deep golden color and sweet flavor that defines the dish.
Can I prepare this French Onion Pasta Recipe ahead of time?
You can caramelize the onions a day in advance and refrigerate them. Then finish the sauce and pasta cooking on the day you plan to serve, which makes meal prep easier.
What cheese substitutes can I use if I don’t have Gruyere?
If Gruyere isn’t available, Fontina or Emmental cheeses make good alternatives. They melt smoothly and bring a similar nutty, creamy flavor that complements the onions perfectly.

Ingredients
For the Onion Base
- 3 tablespoons olive oil
- 2 tablespoons unsalted butter
- 3 large yellow onions, sliced into rings 1/8-inch thick (Mandoline recommended)
- 1/8 teaspoon salt
- 1/8 teaspoon pepper
For the Sauce
- 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)
- 1 12 oz. 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 tsp dried)
- 2 teaspoons fresh thyme, minced (or 3/4 tsp dried)
- 1/2 teaspoon dried oregano
- 1/2 teaspoon paprika
- 1/2 teaspoon pepper
For the Pasta and Cheese
- 1 pound short cut pasta, uncooked (preferably orecchiette)
- 5 oz. 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 7-quart Dutch oven over medium heat. Add the sliced onions along with 1/8 teaspoon salt and 1/8 teaspoon pepper. Cook the onions, stirring occasionally, until they become dark golden brown and caramelized, about 30-35 minutes. Lower the heat and add more butter or olive oil if the onions start to scorch to avoid burning.
- Sauté garlic and seasonings: Once the onions are caramelized, stir in the minced garlic, red pepper flakes, soy sauce, and Worcestershire sauce. Cook this mixture for about 30 seconds to release aromas and combine flavors.
- Prepare the sauce base: Pour in the water and half of the evaporated milk. Whisk the cornstarch with the remaining evaporated milk until smooth, then add this to the pot. Bring the mixture to a boil over high heat, stirring in the beef bouillon and all the herbs and seasonings (parsley, thyme, oregano, paprika, and pepper).
- Cook the pasta: When the liquid reaches a boil, add the uncooked pasta and reduce heat to a medium-high simmer. Cook uncovered for 20-25 minutes, stirring frequently to prevent sticking and burning. Arrange the pasta evenly so it is submerged in the liquid. If needed, add a bit more water during cooking to maintain enough liquid. The pasta should be al dente with some remaining liquid to act as the sauce.
- Incorporate cheeses: Remove the pot from heat. Gradually stir in the shredded Gruyere cheese in small handfuls, allowing it to melt fully before adding the next. After Gruyere is melted, stir in the Parmesan cheese until combined and smooth. Taste and adjust seasoning with salt and pepper if needed. For a saucier texture, add extra water or milk as desired.
- Serve and garnish: Spoon the cheesy French onion pasta into bowls and garnish with fresh parsley if you like. Serve immediately for a warm and satisfying meal.
Notes
- Using a mandoline for slicing onions ensures even thickness for uniform caramelization.
- If you prefer a richer flavor, substitute water with beef broth and omit the beef bouillon.
- Be patient during caramelization; low and slow cooking develops the best deep onion flavor.
- Stir the pasta frequently while cooking to prevent it from sticking to the bottom of the pot.
- Adjust seasoning at the end as evaporated milk and bouillon can add saltiness.
- Orecchiette or other short pasta shapes work best to hold the sauce.
- This recipe can be made vegetarian by skipping Worcestershire sauce and beef bouillon and using vegetable broth instead.
