Step‑by‑Step Instructions for Creamy French Onion Soup Pasta Recipe
Step 1: Caramelize the Onions
Begin by thinly slicing 2 large onions, then heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions along with a pinch of salt, and sauté them gently for about 30–40 minutes, stirring frequently until they turn a rich, golden brown. If the onions begin to stick, add a splash of beef broth to deglaze the pan and enhance their flavor.
Step 2: Prepare the Béchamel Sauce
In a separate saucepan, melt 3 tablespoons of butter over medium heat. Once melted, whisk in 3 tablespoons of flour and cook for about 2 minutes until bubbly and light golden, ensuring there’s no raw flour taste. Gradually add 2 cups of heavy cream while continuously whisking, and let it simmer until thickened, around 5-7 minutes. Stir in ⅔ of the caramelized onions, season with salt and pepper, and add parsley for flavor.
Step 3: Cook the Pasta
Bring a large pot of salted water to a boil and add 8 ounces of cavatappi macaroni. Cook the pasta according to package instructions until it is al dente, typically about 8-10 minutes. Drain the pasta and set it aside, reserving a bit of the pasta water to loosen the sauce if needed. This step ensures that your French Onion Soup Pasta holds its texture after baking.
Step 4: Combine the Pasta and Sauce
In the large skillet that held the caramelized onions, combine the cooked cavatappi with the creamy béchamel sauce. Mix thoroughly to ensure all pasta is evenly coated with the luscious sauce, adding a little reserved pasta water if necessary to achieve a creamy consistency. This rich mixture is the heart of your French Onion Soup Pasta, so be generous in blending flavors.
Step 5: Assemble the Dish
Preheat your oven to 350°F (175°C). Transfer the pasta mixture into a greased baking dish, spreading it evenly. Top with the remaining caramelized onions and sprinkle a generous amount of crispy breadcrumbs made from a baguette, ensuring they cover the surface nicely. This will give the dish its delightful crunchy topping after baking.
Step 6: Bake to Perfection
Place the baking dish in the preheated oven and bake uncovered for 10-15 minutes, until the breadcrumbs are golden brown and crispy. As it bakes, the aromas will fill your kitchen! Watch closely to avoid burning the breadcrumbs, which should be a nice, crispy contrast to the creamy pasta beneath.
Step 7: Serve and Garnish
Remove the baked French Onion Soup Pasta from the oven and let it sit for a couple of minutes to set. Serve hot, garnished with freshly chopped parsley for a fresh pop of color and flavor. This dish is perfect for sharing, so gather your loved ones and enjoy a cozy meal rich in comfort and taste.

Creamy French Onion Soup Pasta Recipe FAQs
What type of onions should I use for best flavor?
Absolutely! For the richest flavor, I recommend using yellow onions or sweet onions. Their natural sugars caramelize beautifully, providing a sweet depth that enhances the entire dish. Avoid using red onions, as they can be more pungent and don’t caramelize as nicely.
How can I store leftovers of the French Onion Soup Pasta?
For sure! Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. Let the pasta cool completely before sealing to prevent moisture from building up inside. This helps maintain the texture and flavor of your beautiful dish.
Can I freeze French Onion Soup Pasta?
Yes, indeed! To freeze, portion the pasta into airtight containers or freezer-safe bags. It will keep well for up to 2 months. When you’re ready to enjoy it again, simply thaw in the fridge overnight, then reheating it in the oven is best to help revive that lovely creamy texture.
How do I refresh the breadcrumb topping when reheating?
Great question! To get that crispy breadcrumb topping back, reheat your baked pasta in the oven at 350°F (175°C) for about 10 minutes. You can also drizzle a little olive oil or butter on top before popping it in the oven for extra crunch and flavor. Enjoying that lovely texture makes a big difference!
Can I customize this recipe for dietary restrictions?
Absolutely! To make this dish vegan, swap heavy cream for full-fat coconut milk and use nutritional yeast instead of parmesan cheese. You can also substitute vegetable broth for the beef broth. Additionally, to cater to gluten-sensitive diners, try using gluten-free pasta and flour—you’ll still enjoy the delightful creamy goodness!
What if my béchamel sauce ends up lumpy?
No worries at all! If your béchamel sauce gets lumpy, whisk in a splash of ice-cold water while stirring vigorously. This technique helps break up any clumps and returns your sauce to the smooth and creamy consistency desired for your French Onion Soup Pasta. Patience and a little tender loving care will get it right back on track!
