Step‑by‑Step Instructions for Creamy French Onion Soup Pasta
Step 1: Caramelize Onions
Begin by thinly slicing the five onions. In a large skillet, heat 1 tablespoon of olive oil over medium heat and add the onions. Sauté them for 30-40 minutes, stirring occasionally, until they turn a deep golden brown and caramelized. If desired, sprinkle in 1 teaspoon of sugar to enhance sweetness, ensuring a rich, flavorful base for your French Onion Soup Pasta.
Step 2: Prepare Béchamel Sauce
Once the onions are caramelized, reduce the heat to low-medium and add 1 tablespoon of flour to the skillet, stirring constantly to create a roux. Gradually whisk in 3 cups of heavy cream, ensuring the mixture is smooth. If it becomes lumpy, add 3 tablespoons of ice-cold water to help it thicken. Mix in ⅔ of the caramelized onions, along with 1 teaspoon of salt, 1 tablespoon of garlic powder, 1 tablespoon of smoked paprika, and ½ teaspoon of nutmeg to enhance the béchamel flavor.
Step 3: Cook Pasta
In a large pot, bring salted water to a boil, then add 300 g of cavatappi macaroni. Cook the pasta until just shy of al dente, about 7-8 minutes, to prevent it from becoming too soft in the oven. Drain the pasta and reserve some cooking water. This will help adjust the consistency of your sauce later if needed.
Step 4: Combine Ingredients
In a large bowl, mix the drained cavatappi with the prepared béchamel sauce, stirring until the pasta is fully coated. Transfer this creamy mixture to a baking dish, and top it with the remaining caramelized onions for added depth. For a delightful crunch, sprinkle the top generously with homemade breadcrumbs made from ½ baguette.
Step 5: Bake to Perfection
Preheat your oven to 350°F (175°C) and place the pasta dish inside. Bake for 10-15 minutes, or until the top is golden brown and crispy. Keep an eye on it to prevent burning, as the combination of the béchamel and breadcrumbs can achieve a beautiful crust that perfectly complements your Creamy French Onion Soup Pasta.
Step 6: Garnish and Serve
Once removed from the oven, allow the dish to cool for a few minutes. Garnish generously with fresh parsley for a pop of color and freshness. Serve warm, enjoying the comforting flavors and textures that this delectable French Onion Soup Pasta has to offer.
Make Ahead Options
Preparing this Creamy French Onion Soup Pasta ahead of time is a fantastic way to save precious minutes on busy weeknights! You can caramelize the onions and prepare the béchamel sauce up to 24 hours in advance; simply store them in airtight containers in the refrigerator to preserve their rich flavors. Cook the pasta just shy of al dente, chill it, and mix everything together before baking. When you’re ready to serve, just combine the ingredients in a baking dish, top with breadcrumbs, and bake at 350°F (175°C) for 10-15 minutes until golden. This way, you’ll enjoy all the comforting deliciousness without the last-minute rush!
