Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize the Onions
Begin by slicing the onions thinly and heating 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions and a pinch of salt, allowing them to sauté for 30-40 minutes, stirring occasionally. You want them golden brown and caramelized; if they begin to stick, add a splash of beef broth to deglaze the pan and enhance their flavor.
Step 2: Prepare the Béchamel Sauce
In the same skillet used for the onions, melt 3 tablespoons of butter over medium heat. Whisk in 3 tablespoons of flour and cook for about a minute until bubbly. Gradually pour in 1 cup of heavy cream while continuously stirring to avoid lumps. Once thickened, incorporate ⅔ of the caramelized onions, seasoning with salt, pepper, and parsley. Stir in Parmesan cheese for that rich, creamy essence.
Step 3: Cook the Pasta
Bring a large pot of salted water to a boil. Add 8 ounces of cavatappi pasta and cook according to the package instructions until just under al dente, about 1-2 minutes less than advised. Reserve about a cup of pasta water, then drain the pasta and set aside. This will help create a silky sauce once combined with the béchamel.
Step 4: Combine Pasta and Sauce
In the skillet with the béchamel sauce, gently fold in the cooked cavatappi pasta, ensuring each piece is well coated with the creamy mixture. If the sauce is too thick, add a bit of the reserved pasta water until you reach the desired consistency. This step is crucial for achieving the perfect texture in your French Onion Soup Pasta.
Step 5: Assemble and Bake
Preheat your oven to 350°F (175°C). Transfer the pasta mixture into a greased 9×13-inch baking dish, spreading it out evenly. Top with the remaining caramelized onions and a generous layer of crispy breadcrumbs. Bake in the preheated oven for 10-15 minutes until the top is golden and bubbling, delivering that delightful hybrid of pasta and soup flavors.
Step 6: Serve and Enjoy
Once baked, allow the dish to sit for a few minutes before serving. This French Onion Soup Pasta is best enjoyed warm, topped with fresh parsley for a pop of color and flavor. Serve it alongside a simple green salad or crusty bread for a complete meal that comforts and delights!

How do I choose the right onions for this recipe?
Absolutely! For the best flavor, use yellow onions as they provide that perfect balance of sweetness and umami when caramelized. If you prefer a milder taste, shallots are a fantastic alternative. Avoid onions with dark spots or a mushy texture, as they won’t yield the best results.
What’s the best way to store leftover French Onion Soup Pasta?
Very simple! Store your leftover pasta in an airtight container in the fridge for up to 3-4 days. Make sure it cools completely before sealing it to help retain moisture and freshness. For longer storage, you can freeze it for up to 2 months; just portion it out into freezer-safe containers and cover tightly.

Certainly! To freeze this delicious dish, allow it to cool completely and then transfer it to freezer-safe containers or resealable bags. It’s best to portion it out for quick meals later. Make sure to remove as much air as possible before sealing. When you’re ready to enjoy it, thaw it overnight in the fridge and reheat in the oven.
What should I do if my béchamel sauce is lumpy?
If you find your béchamel sauce has become lumpy, don’t worry! Simply whisk ice-cold water, a tablespoon at a time, into the sauce while continuously stirring. This helps to smooth it out. Alternatively, you could blend the sauce with an immersion blender for a velvety finish.
Are there any dietary considerations for French Onion Soup Pasta?
Definitely! This dish can be easily adjusted to fit various dietary needs. For a vegetarian option, substitute beef broth with vegetable broth.

Always check labels for allergens when using packaged ingredients.
How can I achieve the perfect crispy breadcrumb topping?
For a golden, crunchy topping, mix your breadcrumbs with a bit of olive oil before spreading them over the pasta. Bake at 350°F (175°C) for about 10-15 minutes, keeping a close eye on them as they cook.
