Step‑by‑Step Instructions for Creamy French Onion Soup Pasta
Step 1: Caramelize Onions
Begin by thinly slicing the onions. In a large skillet, heat a generous drizzle of olive oil over medium heat. Add the sliced onions and sauté, stirring occasionally for about 30–40 minutes until they turn a beautiful golden brown. If they start to stick, pour in the beef broth and let the mixture simmer to deglaze the pan, enhancing the rich flavor.
Step 2: Prepare Béchamel Sauce
Once your onions are perfectly caramelized, reduce the heat and melt 3 tablespoons of butter in the same skillet. Whisk in 1 tablespoon of flour, cooking for 1-2 minutes until it’s lightly golden. Gradually pour in 3 cups of heavy cream while whisking continuously, letting the sauce thicken and bubble gently for about 5 minutes. Stir in two-thirds of the caramelized onions, seasoning with salt, pepper, and fresh parsley.
Step 3: Cook Pasta
Bring a large pot of salted water to a rolling boil. Add 300g of cavatappi macaroni and cook until just under al dente, about 2 minutes shy of package instructions. Drain the pasta, reserving a cup of the pasta water, and set aside. This ensures that the pasta will absorb the flavors of the creamy béchamel sauce without becoming overcooked.
Step 4: Mix Together
In a large mixing bowl, combine the cooked pasta with the béchamel sauce, tossing until every piece is well-coated. If the mixture seems too thick, add a splash of reserved pasta water to achieve your desired consistency. This creamy amalgamation will be the base for your delectable French onion soup pasta.
Step 5: Bake
Preheat your oven to 350°F (175°C). Transfer your creamy pasta mixture to a baking dish, spreading it evenly. Layer the remaining caramelized onions on top, followed by a generous sprinkle of breadcrumbs for that perfect crunch. Bake in the preheated oven for 10-15 minutes until the top is golden and crisp, creating an inviting texture to contrast the creamy pasta underneath.
Step 6: Serve
After baking, take your creamy French onion soup pasta out of the oven and let it rest for a few minutes. Serve it hot, garnished with extra chopped parsley for a burst of color and freshness. This delightful dish is best enjoyed immediately, allowing the creamy textures and rich flavors to shine in every comforting bite.

Creamy French Onion Soup Pasta Recipe FAQs
What type of onions are best for caramelizing?
Absolutely! For caramelizing, I recommend using yellow onions due to their natural sweetness. They break down beautifully and develop a rich flavor when cooked slowly. Sweet onions like Vidalia can also work, but avoid red onions as they tend to have a sharper taste.
How should I store leftover French Onion Soup Pasta?
After enjoying your delicious meal, store any leftovers in an airtight container for up to 3-4 days in the fridge. It’s best to reheat it in the oven with a splash of cream or milk to restore its creamy consistency and prevent it from drying out.
Can I freeze French Onion Soup Pasta?
Very! To freeze your French onion soup pasta, let it cool completely before transferring it to an airtight container or freezer-safe bag. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it again, thaw it overnight in the fridge and reheat in the oven for the best texture.
What if my béchamel sauce is lumpy?
Don’t worry! If your béchamel sauce ends up lumpy, simply whisk in a splash of ice-cold water and continue stirring over low heat. This should smooth it out. Alternatively, you can use an immersion blender to blend the sauce until it’s velvety and lump-free.
Is this recipe suitable for vegetarians?
Yes! To make it vegetarian-friendly, substitute the beef broth with vegetable broth and use nutritional yeast instead of Parmesan cheese. This will still provide a depth of flavor while keeping it entirely plant-based, making it a perfect dish for everyone to enjoy!
How can I enhance the flavor of the caramelized onions?
To deepen the flavor of your caramelized onions, consider adding a pinch of salt at the beginning. This helps draw moisture out, allowing them to cook evenly. You can also splash in a bit of balsamic vinegar or white wine towards the end of cooking to add a lovely acidity that complements the sweetness!
