Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize Onions
Begin by thinly slicing the onions and heating 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions and a pinch of salt, stirring occasionally for 30-40 minutes until they become golden brown and caramelized. For an extra touch of sweetness, feel free to sprinkle in a teaspoon of sugar to speed up the caramelization process.
Step 2: Prepare Béchamel Sauce
Once the onions are beautifully caramelized, transfer them onto a plate and set aside. In the same skillet, melt 2 tablespoons of butter over low heat. Whisk in 2 tablespoons of flour, cooking for about 1-2 minutes until it forms a paste. Gradually add 1 cup of heavy cream, stirring continuously until the mixture thickens, about 3-5 minutes. Mix in ⅔ of the caramelized onions, salt, pepper, parmesan cheese, and fresh parsley, turning off the heat once well combined.
Step 3: Cook Pasta
Fill a large pot with water and bring it to a boil. Add a generous pinch of salt and 8 ounces of cavatappi macaroni, cooking for 7-9 minutes until just under al dente. Drain the pasta and return it to the pot. Pour the béchamel sauce over the pasta and stir until every piece is generously coated, resulting in the creamy goodness of French Onion Soup Pasta.
Step 4: Bake
Preheat your oven to 350°F (175°C). Transfer the pasta mixture into a greased baking dish and spread it out evenly. Top with the remaining caramelized onions and a handful of homemade breadcrumbs. Bake in the preheated oven for 10-15 minutes or until the top is golden and crispy, creating an inviting texture that contrasts with the creamy pasta underneath.
Step 5: Serve
Remove the dish from the oven and let it cool for a few minutes. Serve your comforting French Onion Soup Pasta hot, garnished with fresh parsley for a pop of color and added flavor. Dig into this warm, creamy delight and relish every bite of this crowd-pleasing dish!
