Step‑by‑Step Instructions for French Onion Soup Pasta Recipe
Step 1: Caramelize Onions
Begin by thinly slicing your onions and heating a large skillet over medium heat. Add a generous drizzle of olive oil, then toss in the sliced onions. Cook for 30-40 minutes, stirring occasionally, until they become golden brown and caramelized. For added sweetness, sprinkle in a teaspoon of sugar halfway through the cooking process.
Step 2: Prepare Béchamel Sauce
Once the onions are caramelized to perfection, move them to the side of the skillet. In the same pan, melt a couple of tablespoons of butter over medium heat. Whisk in flour and gradually add heavy cream, stirring constantly until the mixture thickens and bubbles gently. Mix in about two-thirds of the caramelized onions along with salt, pepper, and fresh parsley.
Step 3: Cook Pasta
In a large pot, bring salted water to a boil. Add your cavatappi macaroni, cooking it until just shy of al dente, usually about 2 minutes less than package instructions. This step is crucial as the pasta will continue to cook while baking. Drain and set aside, allowing the pasta to cool slightly.
Step 4: Combine Ingredients
Transfer the cooked pasta into the skillet with the béchamel sauce, ensuring the pasta is evenly coated with the creamy mixture. Gently fold in the remaining caramelized onions, making sure every spiral of pasta is infused with that sweet, oniony flavor. This harmonious blend is the heart of your French onion soup pasta.
Step 5: Assemble and Bake
Preheat your oven to 350°F (175°C). Now, transfer the pasta mixture into a greased baking dish, spreading it out evenly. Top it generously with the remaining caramelized onions and a layer of crispy homemade breadcrumbs, ensuring an even coverage for that delectable crunch.
Step 6: Serve
Bake the assembled dish in the preheated oven for 10-15 minutes, or until the breadcrumbs are golden and crisp. Once ready, remove from the oven and let it rest for a few minutes before serving. This warm, comforting French onion soup pasta is perfect for sharing and is sure to satisfy everyone’s cravings!

Expert Tips for French Onion Soup Pasta
-
Slow Caramelization: Patience is key! Allow the onions to caramelize slowly over medium heat for the best depth of flavor. Avoid cranking up the heat to rush the process, as it can lead to burnt onions.

Smooth Béchamel: If your béchamel sauce turns lumpy, don’t fret! Simply whisk in a splash of ice-cold water while stirring to regain the silky texture you want for this French Onion Soup Pasta recipe.
-
Cook Pasta Al Dente: Remember to cook your pasta slightly under al dente—around 2 minutes less than package instructions. It will soften more while baking, ensuring it’s perfectly tender without becoming mushy.
-
Use Fresh Ingredients: For the best results, opt for fresh herbs, high-quality broth, and ingredients like freshly grated cheese. This will elevate the flavors and make your dish truly shine.
-
Customize Flavors: Don’t hesitate to experiment with different types of cheese or add sautéed vegetables like mushrooms or spinach to enhance this dish and suit personal tastes!
