How to Make French Onion Soup Pasta Recipe

Step 1: Caramelize those onions

Begin by thinly slicing the onions into delicate strips—they’ll melt into sweet perfection over time. Heat olive oil in a large skillet on medium heat, and let those onions cook low and slow for 30 to 40 minutes, stirring occasionally to avoid burning. If you want to speed up the caramelization, sprinkle a teaspoon of sugar. When you see those rich golden edges forming, add the beef broth to deglaze the pan and simmer a bit longer. This step builds the backbone of our flavor.

Step 2: Whip up the creamy béchamel sauce

In the same skillet, melt some butter over low to medium heat. Whisk in the flour and cook for a minute to form a roux, then slowly add the heavy cream, whisking constantly so the sauce thickens without lumps. If any lumps do appear, whisk in a splash of ice-cold water—it’s a neat trick to smooth things out quickly! Stir in two-thirds of the caramelized onions, salt, pepper, chopped parsley, nutmeg, garlic powder, smoked paprika, and Parmesan cheese to make a silky, flavor-packed sauce.

Step 3: Cook the pasta just right

Bring a large pot of salted water to boil and cook your cavatappi pasta until it’s just shy of al dente—the noodles will finish cooking in the oven, soaking up the luscious sauce, so you don’t want them too soft at this stage.

Step 4: Combine and bake

Toss the pasta into the béchamel-onion sauce, stirring well so every curl of cavatappi is coated in creamy goodness. Transfer the mixture to an oven-safe skillet or baking dish, then layer the remaining caramelized onions on top. Finally, sprinkle the crunchy homemade breadcrumb mixture made from the baguette, olive oil, oregano, salt, and pepper over everything. Bake uncovered at 350°F (175°C) for 10 to 15 minutes until the topping is beautifully golden and crispy.

How to Serve French Onion Soup Pasta Recipe

Garnishes

When serving, scatter some freshly chopped parsley or extra grated Parmesan on top for a burst of freshness and a lovely finishing touch. You could also add a few thyme leaves or a drizzle of truffle oil for an extra special treat that brings out the dish’s earthy tones.

Side Dishes

This French Onion Soup Pasta Recipe pairs wonderfully with a crisp green salad dressed with a light vinaigrette to cut through the richness. Roasted vegetables or a simple garlic bread also make excellent companions, ensuring every bite is balanced and satisfying.

Creative Ways to Present

For a cozy dinner party vibe, serve portions in individual oven-safe ramekins topped with the crispy breadcrumbs and a little extra Parmesan. Not only does this look charming, but it also gives everyone their own bubbling, golden brown masterpiece!

Make Ahead and Storage

Storing Leftovers

Place any leftovers into an airtight container and refrigerate for up to three days. The flavors will continue to meld, making the dish even tastier the next day.

Freezing

If you want to freeze this French Onion Soup Pasta Recipe, transfer cooled portions into freezer-safe containers or bags. It freezes well for up to two months. Just be mindful that the crispy breadcrumb topping will lose some crunch after thawing.

Reheating

For reheating, thaw overnight in the fridge if frozen, then warm gently in the oven at 350°F (175°C) for about 10-15 minutes to revive some crispness. Microwave reheating works too but won’t keep the topping crunchy.

FAQs

Can I use a different type of pasta for this recipe?

Absolutely! While cavatappi is fantastic for holding the sauce, any short pasta like penne, rigatoni, or fusilli will work just as well.

Is there a vegetarian version of this French Onion Soup Pasta Recipe?

Yes! Simply swap the beef broth for a rich vegetable broth, and you’ll still get that deep, comforting flavor without the meat base.

Can I make this recipe gluten-free?

Yes, just use gluten-free pasta and substitute the flour with a gluten-free thickener like cornstarch or a gluten-free flour blend for the béchamel.

How do I avoid lumpy béchamel sauce?

Whisk constantly while adding the cream slowly, and if lumps form, stir in a little ice-cold water while whisking vigorously to smooth it out.

What can I do if I don’t have heavy cream?

You can combine milk with a bit of melted butter as a substitute, but keep in mind the sauce might be less rich and creamy.
