How to Make French Onion Soup Pasta Recipe
Step 1: Caramelize the Onions
Start by thinly slicing your onions into long, delicate strips — this helps them cook evenly and become irresistibly tender. Heat a large skillet over medium heat with olive oil, then add your onions. Patience is key here: sauté them slowly for 30 to 40 minutes, stirring occasionally, so they soften and turn a deep golden brown without burning. If you want to speed up this process and introduce a subtle sweetness, sprinkle in a teaspoon of sugar. Once they start to stick a bit, pour in the beef broth and let everything simmer gently for about 10 minutes. The broth adds savory depth and helps create that classic French onion flavor.
Step 2: Prepare the Béchamel Sauce
Using the same skillet (no need to dirty another dish!), melt some butter over low to medium heat. Whisk in the flour and cook briefly for about a minute — this forms the roux that will thicken your sauce. Gradually add the heavy cream while whisking continuously, allowing the sauce to thicken to a luscious, creamy consistency. If lumps appear, don’t panic! Stirring in some ice-cold water or whisking vigorously will smooth it right out. Next, fold in two-thirds of your caramelized onions for that unmistakable sweetness mingled with the creamy base. Season with salt, pepper, fresh parsley, and a good handful of Parmesan cheese to round out the flavors.
Step 3: Cook the Pasta and Combine
Meanwhile, bring a large pot of salted water to boil and cook your cavatappi pasta until just shy of al dente — it will finish cooking once it bakes. Drain the pasta and combine it immediately with your béchamel sauce and caramelized onions mixture, ensuring every twist and turn of the pasta is drenched in that flavorful cream.
Step 4: Assemble and Bake
Transfer your saucy pasta into a baking dish. Sprinkle the remaining third of the caramelized onions on top for an extra layer of flavor and texture. For the finishing touch, scatter the savory homemade breadcrumbs, made by tossing torn baguette pieces with olive oil, oregano, salt, and pepper. Bake everything uncovered at 350°F (175°C) for 10 to 15 minutes until the top is irresistibly golden and crisp — that crunchy topping contrasts beautifully with the creamy pasta beneath.
How to Serve French Onion Soup Pasta Recipe

Garnishes
Top your dish with a sprinkle of fresh parsley for a vibrant pop of green that makes it look as good as it tastes. A light dusting of freshly grated Parmesan also adds a nutty aroma and extra cheesiness that’s hard to resist. If you’re feeling indulgent, a few grates of fresh black pepper will add warmth and depth to every bite.
Side Dishes
This pasta works wonderfully alongside light and fresh side dishes to balance the richness. A crisp green salad with a tangy vinaigrette is perfect to cut through the creamy sauce. Roasted vegetables such as asparagus or Brussels sprouts also offer a lovely contrast in texture and earthiness. And for a heartier meal, crusty bread or garlic bread are excellent to mop up any leftover sauce.
Creative Ways to Present
For a fun twist, serve this French Onion Soup Pasta Recipe in individual ramekins or small cast-iron skillets to recreate the classic onion soup experience, complete with the crispy breadcrumb topping. Drizzle a little extra olive oil or melt a thin slice of Gruyère over the top before baking to mimic that beautifully gratinéed finish. This presentation not only impresses guests but makes each serving feel special and personal.
Make Ahead and Storage
Storing Leftovers
Store any leftover pasta in an airtight container in the refrigerator for up to 3 days. It’s best to keep the topping separate if you want it to stay crispy; otherwise, it may soften and lose its crunch. When ready to eat, just reheat gently to avoid drying out the creamy sauce.
Freezing
You can freeze this French Onion Soup Pasta Recipe for up to 2 months. Use a freezer-safe container and layer the pasta and sauce carefully to maintain texture. The breadcrumb topping is best added fresh after thawing to keep its signature crunch. Thaw the dish overnight in the fridge before reheating for best results.
Reheating
Reheat leftovers in the oven at 325°F (160°C) to revive the crispiness of the topping and warm the sauce evenly. If you’re in a rush, the microwave works too, but cover the dish loosely to prevent the pasta from drying out. Stir halfway through to distribute heat uniformly.
FAQs
Can I use a different type of pasta for the French Onion Soup Pasta Recipe?
Absolutely! While cavatappi is fantastic for holding onto the sauce, feel free to swap it with penne, rigatoni, or even elbow macaroni. Just make sure to cook it al dente so it doesn’t become mushy after baking.
Is there a vegetarian version of this recipe?
Yes, you can easily make a vegetarian French Onion Soup Pasta Recipe by substituting the beef broth with vegetable broth. The caramelized onions and rich béchamel sauce will still provide plenty of flavor without the meat element.
Can I make the caramelized onions ahead of time?
Definitely! Caramelized onions can be prepared a day or two in advance and stored in the fridge. This actually helps deepen their flavor, making your pasta even more delicious when you’re ready to cook.
What can I use instead of heavy cream?
If you want a lighter version, you can use whole milk combined with a bit of butter to mimic the richness of heavy cream. However, the sauce won’t be quite as thick or creamy, so adjust seasoning and cooking time accordingly.
How do I ensure my béchamel sauce doesn’t get lumpy?
The key is whisking constantly while gradually adding the cream to the roux. If lumps form, rapid whisking or adding a splash of cold water usually smooths it out quickly. Patience and steady stirring are your best friends here!
