Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize the Onions
Begin by thinly slicing five medium-sized onions. Heat 2 tablespoons of olive oil in a large skillet over medium heat, then add the onions. Cook them for 30-40 minutes, stirring occasionally, until they turn a rich golden brown and become soft. If they start to stick, add a splash of beef broth to keep them moving along, enhancing the sweetness of your French onion soup pasta.
Step 2: Prepare the Béchamel Sauce
Once the onions are beautifully caramelized, lower the heat and melt 3 tablespoons of butter in the same skillet. Whisk in 3 tablespoons of flour until smooth, forming a roux. Gradually pour in 1 cup of heavy cream while continuously whisking to prevent lumps. Cook for about 5-7 minutes, or until the sauce thickens and bubbles gently, creating the creamy base for your French onion soup pasta.
Step 3: Combine Ingredients
Stir ⅔ of the caramelized onions into the béchamel sauce, mixing well to incorporate their sweet flavor throughout. Season with salt, pepper, 1 teaspoon of oregano, and ⅓ cup of grated Parmesan cheese for a savory depth. The creamy mixture should be rich and inviting, setting the stage for your pasta addition.
Step 4: Cook the Pasta
In a separate pot, bring salted water to a boil and cook 12 ounces of cavatappi macaroni until just shy of al dente, about 7-9 minutes. Drain the pasta and immediately mix it into the béchamel sauce, ensuring every twist is coated in that luscious creamy goodness. This step is crucial for your French onion soup pasta, as it allows the flavors to meld beautifully.
Step 5: Assemble and Bake
Preheat your oven to 350°F (175°C). Transfer the pasta mixture into a greased baking dish. Layer the remaining caramelized onions on top, followed by a generous sprinkle of homemade breadcrumbs. Drizzle with olive oil to encourage a golden finish, then place in the oven. Bake for 10-15 minutes, or until the top is crisp and golden, promising a delightful crunch to your creamy French onion soup pasta.
Step 6: Garnish and Serve
Once out of the oven, let the dish rest for a few minutes to set. Finely chop some fresh parsley and sprinkle it over the top for a pop of color and freshness. Serve warm, and get ready to enjoy the creamy, comforting flavors of French onion soup pasta with friends and family, bringing cozy vibes to your dinner table!

How to Store and Freeze French Onion Soup Pasta
Fridge: Store leftover French onion soup pasta in an airtight container for up to 3-4 days. Make sure it’s completely cooled before sealing to maintain freshness.
Freezer: For longer storage, freeze the pasta in a freezer-safe container for up to 2 months. Portion the pasta for easy reheating later.
Reheating: Thaw in the fridge overnight before reheating. Warm in the oven at 350°F (175°C) for about 20 minutes or in the microwave until heated through, stirring occasionally.
Re-crisping Breadcrumbs: If you want to revive that crispy topping after freezing, sprinkle with a little olive oil and broil for a few minutes while reheating.
Make Ahead Options
These creamy French onion soup pasta dishes are perfect for busy weeknights and easy meal planning! You can prepare the caramelized onions and béchamel sauce up to 24 hours in advance, storing them in an airtight container in the refrigerator to maintain their rich flavors. Additionally, cook the cavatappi pasta slightly under al dente (about 7-9 minutes), and combine it with the sauce and onions just before baking. For best results, assemble everything, but wait to add the breadcrumb topping until you are ready to bake. Simply bake at 350°F (175°C) for 10-15 minutes (until golden), and enjoy a comforting meal that’s just as delicious as if you made it from scratch!

French Onion Soup Pasta Recipe FAQs

Absolutely! For this recipe, I recommend selecting firm onions without any dark spots or soft areas. Yellow onions are ideal due to their sweetness when caramelized, but you can also use sweet onions like Vidalia for a milder flavor.
