How to Make French Onion Soup Pasta Recipe

Step 1: Prepare the Breadcrumbs

Start by making your homemade herbed breadcrumbs. Tear half a baguette into chunks and pulse in a food processor or blender until you get coarse crumbs. Toss them with olive oil, salt, pepper, and oregano, then toast them in a hot skillet until golden and deeply fragrant. These will be your magic crunch on top!

Step 2: Caramelize the Onions

Thinly slice your onions into long, slender strips. Add them to a large skillet with olive oil and let them cook down slowly over medium heat. Stir every few minutes so nothing burns. After about 30-40 minutes, they’ll wilt, deepen in color, and turn sweet. A teaspoon of sugar can help things along, but patience delivers that dreamy, melting texture. Add in beef broth toward the end and let everything simmer until glossy and golden.

Step 3: Cook the Pasta

While your onions caramelize, bring a big pot of salted water to a boil. Add your cavatappi and cook until just under al dente. Remember, the pasta will finish baking in the oven, so keep it a touch firmer than usual for the best texture.

Step 4: Make the Béchamel Sauce

In your onion skillet, melt a bit of butter over low-medium heat. Whisk in flour and cook for a minute to get rid of any raw flavor, then slowly pour in the heavy cream, whisking the whole time. If lumps sneak in, add a splash of ice-cold water and whisk like mad—they’ll smooth right out. Stir in two-thirds of those golden onions plus chopped parsley, salt, pepper, and most of the parmesan. Let the sauce get creamy and thick.

Step 5: Combine Pasta with Sauce

Add your drained cavatappi directly to the skillet of béchamel and onions. Toss everything together until each curl of pasta is coated in the luscious sauce and studded with sweet onion ribbons. Taste and adjust seasoning if needed—it should be beautifully rich and savory!

Step 6: Assemble and Bake

Pour the pasta and sauce into an oven-safe baking dish (or keep it in your skillet if it’s oven-safe). Scatter the rest of the caramelized onions across the top, then sprinkle liberally with the toasted herby breadcrumbs. Bake at 350°F (175°C) uncovered for 10–15 minutes, just until the top is golden, crisp, and irresistible.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

If you find yourself with leftovers (lucky you!), transfer any remaining pasta to an airtight container. Store it in the refrigerator for up to three days. The flavors deepen beautifully, making each leftover bite even more satisfying.

Freezing

You can freeze French Onion Soup Pasta Recipe for up to one month. Let it cool completely, then wrap tightly or transfer portions to freezer-safe containers. Note that the breadcrumb topping will soften, but you can refresh it under the broiler after reheating for a fresh crunch.

Reheating

To reheat, place the pasta in an oven-safe dish, cover with foil, and warm in a preheated oven at 350°F until piping hot. For best results, uncover for the last few minutes to recrisp the breadcrumbs. You can also microwave individual servings, but the oven preserves the crust best!

FAQs

Can I use a different type of pasta?

Absolutely! While cavatappi is wonderful thanks to its spiral shape, penne, fusilli, rigatoni, or even shells will all soak up the creamy sauce and onions beautifully in this French Onion Soup Pasta Recipe.

What if I don’t eat beef?

You can swap in vegetable broth for the beef broth if you’d like to keep things vegetarian. It will have a slightly lighter flavor, but you’ll still get fantastic depth from the caramelized onions and cheese.

Can I caramelize the onions in advance?

Yes! Caramelize the onions a day or two ahead and store them in the fridge. This makes assembly a breeze and can even deepen the rich, sweet flavors once chilled and reheated.

Is there a way to make it gluten free?

Simply use gluten free pasta and swap in a 1-to-1 gluten free flour blend for the béchamel. For breadcrumbs, use gluten free bread or crushed gluten free crackers—the rest of the recipe stays deliciously the same.

What’s the best way to get onions caramelized without burning?

Low and slow is the secret. Keep the skillet over medium or slightly lower heat, and stir regularly. If the onions start to catch, a splash of water or broth helps deglaze the pan and keeps things moist and moving.
