How to Make French Onion Soup Pasta Recipe
Step 1: Slice the Onions
Thinly slice the onions into long strips. This step is crucial as slicing them correctly allows them to caramelize evenly, bringing out their natural sweetness.
Step 2: Caramelize the Onions
Heat a large skillet or pan over medium heat and add olive oil. Sauté the onions for 30–40 minutes, stirring occasionally. Allow them to caramelize slowly without burning. If they begin sticking, add beef broth to help deglaze the pan and enhance their flavor.
Step 3: Prepare the Béchamel Sauce
In the same skillet, melt butter over low-medium heat. Whisk in flour and cook for a minute before gradually adding heavy cream. Let the sauce thicken—this creamy base is what makes our pasta so indulgent! If any lumps form, whisking vigorously with ice-cold water will do wonders.
Step 4: Combine Flavors
Stir in ⅔ of the caramelized onions into your béchamel sauce and let it simmer while seasoning with salt, pepper, chopped parsley, and Parmesan cheese. This step allows all those lovely flavors to meld together beautifully!
Step 5: Cook the Pasta
Meanwhile, bring a large pot of salted water to a boil and cook your cavatappi until just shy of al dente. Since they’ll finish cooking in the oven, this ensures they won’t be mushy when served.
Step 6: Mix Everything Together
Combine your cooked pasta with the béchamel sauce until well mixed. The creamy sauce should coat each piece of pasta perfectly!
Step 7: Bake Your Dish
Transfer everything into a baking dish and top with remaining caramelized onions and homemade breadcrumbs from your baguette. Bake uncovered at 350°F (175°C) for 10–15 minutes until everything is golden and crisp on top.
Step 8: Serve & Enjoy!
Serve immediately while it’s hot and bubbly! Enjoy every cheesy bite of this comforting French Onion Soup Pasta Recipe—you deserve it!
Pro Tips for Making French Onion Soup Pasta Recipe
Making this French Onion Soup Pasta Recipe is a delightful culinary adventure, and with a few pro tips, you’ll elevate your dish to the next level!

Caramelize Slowly: Take your time while caramelizing the onions. This process enhances the sweetness and depth of flavor, giving your pasta a rich taste.
-
Use Fresh Ingredients: Opt for fresh parsley and high-quality cheese. Fresh ingredients contribute vibrant flavors and make your dish visually appealing.

Monitor the Pasta: Cook the pasta just before al dente. This ensures it retains some firmness, allowing it to absorb the delicious béchamel sauce while baking.
-
Breadcrumbs Matter: For a crunchy topping, consider making your own breadcrumbs by blending leftover bread in a food processor. Homemade breadcrumbs add texture and freshness compared to store-bought ones.
-
Season Wisely: Taste as you go! Adjust seasoning in both the béchamel sauce and pasta mixture to ensure every bite is flavorful.
