Ingredients You’ll Need

Every single ingredient in this French Onion Pasta is chosen with purpose—no fillers, just flavor! From the deeply caramelized onions to the nutty Gruyere and aromatic herbs, each component plays a key role in building this pasta’s irresistible layers of taste, texture, and creaminess.

• Olive Oil & Unsalted Butter: This classic duo ensures the onions caramelize to golden perfection and adds that luxurious mouthfeel.
• Yellow Onions: Slow-cooked and deeply caramelized, they’re the backbone of the sweet, savory flavor in every bite.
• Salt & Pepper: Essential for drawing out the onions’ natural sweetness and balancing the dish.
• Garlic: Adds aromatic depth and that little pop of savoriness that makes everything better.
• Red Pepper Flakes: A pinch adds gentle heat—adjust to your preference for a little kick!
• Worcestershire Sauce & Soy Sauce: Both layer in umami, giving the sauce richness and a hint of tang.
• Water or Beef Broth: Forms the base of the sauce, providing depth; use beef broth for extra savoriness or water if you prefer lighter flavors.
• Evaporated Milk: Brings luxurious creaminess without making the sauce heavy; it’s the secret to a silky finish.
• Cornstarch: Gives the sauce just enough body to coat every piece of pasta beautifully.
• Beef Bouillon: Intensifies all those cozy, brothy notes; swap for more beef broth if you like.
• Fresh Parsley & Thyme, Dried Oregano: These herbs brighten things up and make the kitchen smell absolutely amazing.
• Paprika & Pepper: For warmth and subtle peppery edge.
• Short Cut Pasta (Orecchiette or similar): The perfect shape for catching all those gloriously cheesy onions and sauce.
• Gruyere Cheese: The signature cheese of French onion soup—melty, nutty, and pure magic when paired with caramelized onions.
• Parmesan Cheese: Adds salty depth and finishes the sauce with a bit of sharpness.
• Fresh Parsley (for garnish): Optional, but it adds a lovely burst of color and freshness at the end.

How to Make French Onion Pasta

Step 1: Caramelize the Onions

In a large Dutch oven set over medium heat, melt the butter with olive oil. Add your sliced onions along with a sprinkle of salt and pepper. Let the onions cook for 30-35 minutes, stirring every few minutes—don’t rush this! You want them dark golden brown and meltingly sweet. If they look like they’re sticking or scorching, just turn the heat down or swirl in a little extra butter or oil.

Step 2: Sauté Aromatics & Build Flavor

Once your onions are perfectly caramelized, stir in the minced garlic, red pepper flakes, soy sauce, and Worcestershire sauce. Sauté for about 30 seconds until everything’s super fragrant—this quick step infuses your pasta with irresistible layers of flavor.

Step 3: Make the Sauce & Add Pasta

Pour in the water (or beef broth) and half of the evaporated milk. In a small bowl, whisk the cornstarch into the remaining evaporated milk and then stir it into the pot. Add your bouillon, parsley, thyme, oregano, paprika, and black pepper. Crank up the heat and bring everything to a gentle boil, then stir in the pasta and let it simmer (no lid needed). Cook for 20–25 minutes, stirring often so the pasta doesn’t stick, and add more water if things get a little too thick. The sauce will still be loose at the end—that’s perfect!

Step 4: Stir in the Cheeses

Take the pot off the heat and start stirring in the Gruyere cheese by the handful, letting it melt before you add more. Finish with the Parmesan, stirring until your French Onion Pasta is silky, luscious, and loaded with cheesy goodness. Have a quick taste and adjust your seasoning, then add more water or milk if you want an even saucier finish.

Step 5: Garnish and Serve

Spoon generous bowls of your French Onion Pasta and sprinkle with fresh parsley for a pop of green. Serve piping hot for the dreamiest comfort dinner ever!

Make Ahead and Storage

Storing Leftovers

French Onion Pasta keeps beautifully in the fridge, making it ideal for leftovers. Just let it cool completely, then transfer to an airtight container and refrigerate for up to five days. The flavors get even deeper on day two!

Freezing

You can freeze French Onion Pasta, though the texture will be creamiest when enjoyed fresh. Freeze cooled leftovers in freezer-safe containers for up to two months. Thaw overnight in the fridge before reheating gently.

Reheating

Reheat French Onion Pasta over low heat on the stovetop or in the microwave, adding a splash of water or milk to loosen the sauce if needed. Stir gently as it warms to keep everything silky and cheesy.
