Step‑by‑Step Instructions for Creamy French Onion Soup Pasta Recipe
Step 1: Caramelize the Onions
Begin by thinly slicing your sweet onions, then heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the sliced onions, season with a pinch of salt, and cook for 30-40 minutes, stirring frequently, until they turn a rich golden brown and are fully caramelized. If needed, sprinkle in a teaspoon of sugar to enhance the sweetness during cooking.
Step 2: Prepare the Béchamel Sauce
In the same skillet with the caramelized onions, lower the heat slightly and melt 4 tablespoons of butter. Once melted, whisk in ¼ cup of flour, cooking for about 1-2 minutes until it forms a paste. Gradually add 2 cups of heavy cream, whisking continuously until the sauce thickens and bubbles gently; this should take about 5-7 minutes. Stir in ⅔ of the caramelized onions, along with salt, pepper, chopped fresh parsley, and ½ cup of grated Parmesan cheese.
Step 3: Cook the Pasta
Bring a large pot of salted water to a rolling boil, then add 12 ounces of cavatappi macaroni. Cook the pasta according to package instructions until just shy of al dente, usually around 7-9 minutes. Drain the pasta, reserving a cup of the pasta water, and return it to the pot. This step ensures your pasta achieves the perfect texture once baked.
Step 4: Combine Pasta and Sauce
Pour the thick béchamel sauce over the drained cavatappi in the pot. Mix thoroughly until the pasta is well-coated in the creamy sauce, ensuring each piece is enveloped. If needed, incorporate a splash of reserved pasta water to achieve a creamier consistency. This rich combination makes your French Onion Soup Pasta truly irresistible.
Step 5: Assemble the Dish
Preheat your oven to 350°F (175°C). Transfer the pasta and sauce mixture into a greased 9×13-inch baking dish. Top it with the reserved caramelized onions and spread evenly. Then, sprinkle a generous layer of homemade breadcrumbs over the top, ensuring even coverage for a delightful crunch after baking.
Step 6: Bake to Perfection
Place the baking dish in the preheated oven and bake for 10-15 minutes until the topping turns golden brown and crispy. Keep an eye on it, as ovens can vary; a bubbling edge and golden hue indicate it’s time to remove it. This step will transform your French Onion Soup Pasta into a beautifully baked masterpiece.
Step 7: Serve and Enjoy
Once out of the oven, allow the dish to cool for a few minutes before diving in. Garnish with extra chopped parsley and grated Parmesan if desired. Serve your Creamy French Onion Soup Pasta immediately, sharing the warmth and comfort with family or friends. The combination of flavors and textures will surely impress everyone at the table!

Tips for the Best French Onion Soup Pasta
-
Choose Sweet Onions: They caramelize beautifully, enhancing the dish’s flavor. Avoid using stronger onions as they may overpower the recipe.
-
Perfect Béchamel: For a silky sauce, whisk continuously as you incorporate cream. If lumps form, ice-cold water can help smooth it out quickly.
-
Watch the Pasta: Cook it just shy of al dente to prevent mushiness during baking. Remember, it will continue cooking in the oven!
-
Breadcrumb Crunch: Use fresh bread for the topping for optimal flavor and texture. Pre-made breadcrumbs are a shortcut but won’t give the same crunch.
-
Experiment Freely: Don’t hesitate to mix in veggies or proteins according to your taste and dietary needs. This allows your French Onion Soup Pasta to adapt beautifully to your preferences!
