Step‑by‑Step Instructions for Creamy French Onion Soup Pasta Recipe
Step 1: Caramelize Onions
Start by thinly slicing 2 large yellow onions, then heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions and cook for 30–40 minutes, stirring occasionally, until they are golden brown and caramelized. If the onions begin to stick, add a splash of beef broth to deglaze the pan and enhance their flavor.
Step 2: Prepare Béchamel Sauce
In a separate saucepan, melt 4 tablespoons of butter over medium heat. Whisk in 4 tablespoons of flour, allowing it to cook for about 1 minute. Gradually add 1 cup of heavy cream while whisking steadily until the sauce is smooth and thickened, about 5–7 minutes. Stir in ⅔ of the caramelized onions, seasoning with salt, pepper, and a sprinkle of fresh parsley for extra flavor.
Step 3: Cook Pasta
Bring a large pot of salted water to a boil, then add 8 ounces of cavatappi macaroni. Cook the pasta for about 6-7 minutes, or until just shy of al dente. Drain the pasta, reserving a cup of starchy pasta water, and set it aside while you get ready to combine it with the béchamel sauce.
Step 4: Combine Pasta and Sauce
Transfer the drained pasta into the saucepan with the béchamel sauce. Mix well to ensure all the pasta is evenly coated in the creamy goodness. If the sauce appears too thick, gradually add a little of the reserved pasta water until you reach your desired consistency, making the French Onion Soup Pasta perfectly creamy.
Step 5: Assemble the Dish
Preheat your oven to 350°F (175°C). Pour the pasta mixture into a greased baking dish. Top it with the remaining caramelized onions and finish with a generous layer of homemade breadcrumbs, ensuring an even distribution for a crispy topping.
Step 6: Bake
Place the assembled dish in the preheated oven and bake uncovered for 10-15 minutes, or until the top is golden brown and crispy. Keep an eye on it to prevent burning, as the breadcrumbs should become lightly toasted for that delightful crunch.
Step 7: Serve
Once baked to perfection, remove the Creamy French Onion Soup Pasta from the oven and let it cool for a few minutes. Garnish with extra parsley and serve hot. This comforting dish is perfect for a cozy family meal or an impressive dinner party treat!
