Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize the Onions
Begin by thinly slicing 5 sweet or yellow onions. In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the sliced onions and sauté them for 30-40 minutes, stirring frequently until they turn golden brown and caramelized. If needed, splash in a little beef broth to prevent sticking. The onions should be soft, sweet, and fragrant, filling your kitchen with an irresistible aroma for the French Onion Soup Pasta.
Step 2: Make the Béchamel Sauce
Once your onions are beautifully caramelized, reduce the heat to low and add 2 tablespoons of butter to the skillet. When melted, whisk in 2 tablespoons of flour to form a roux, cooking for about 1 minute until lightly golden. Gradually pour in 1 cup of heavy cream while whisking continuously until thickened, about 5-7 minutes. Stir in the caramelized onions, 1/2 cup of grated Parmesan cheese, and season with salt, pepper, oregano, garlic powder, and a pinch of nutmeg.
Step 3: Cook the Pasta
While your béchamel sauce is coming together, boil a large pot of salted water. Add 8 ounces of cavatappi macaroni and cook until al dente, usually about 8-10 minutes. Drain the pasta and return it to the pot. Pour the creamy béchamel sauce over the drained pasta, gently folding until every piece is coated in that delicious sauce, creating a comforting base for your French Onion Soup Pasta.
Step 4: Prepare for Baking
Preheat your oven to 350°F (175°C). Transfer the pasta and béchamel mixture into a greased baking dish, spreading it evenly. Then, using the remaining caramelized onions, distribute them over the top of the pasta to infuse extra flavor. Finally, sprinkle a generous layer of breadcrumbs over the entire dish to create that perfect crispy topping.
Step 5: Bake the Dish
Place the baking dish in the preheated oven and bake for 10-15 minutes, or until the breadcrumbs are golden brown and crispy. Keep an eye on it to ensure that the top doesn’t burn. The combination of textures—creamy pasta and crunchy topping—is what makes this French Onion Soup Pasta so irresistible.
Step 6: Serve and Enjoy
Once your French Onion Soup Pasta is finished baking, carefully remove it from the oven and let it sit for a few minutes to cool slightly. Garnish with fresh parsley for a pop of color. Serve it warm as a hearty main course, and savor each comforting bite of this creamy and flavorful dish that’s sure to impress at any gathering!
