Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize Onions
Begin by thinly slicing your onions. In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the onions and a pinch of salt, stirring occasionally for about 30-40 minutes. You’ll want them to turn a beautiful golden brown, releasing their sweet aroma. If the onions start to stick, add a splash of beef or vegetable broth to deglaze the pan and continue cooking until caramelized.
Step 2: Make Béchamel Sauce
Once the onions are caramelized, reduce the heat to low and melt 2 tablespoons of butter in the same skillet. Whisk in 2 tablespoons of flour, cooking for about a minute until bubbly. Gradually whisk in 1 cup of heavy cream, stirring continuously until the mixture thickens, approximately 3-5 minutes. Then, mix in the caramelized onions, seasoning with salt, pepper, and freshly grated Parmesan to taste.
Step 3: Cook Pasta
In a large pot, bring salted water to a boil. Add 8 ounces of cavatappi macaroni and cook according to package instructions until it’s just under al dente, about 7-8 minutes. Drain the pasta and reserve a little pasta water in case you need to loosen the sauce later. Set the pasta aside to combine with your flavorful béchamel sauce.
Step 4: Combine Pasta and Sauce
In the skillet with the béchamel sauce, gently fold in the drained cavatappi macaroni. Stir until each piece of pasta is generously coated with the creamy onion sauce. If the mixture feels too thick, add a splash of the reserved pasta water to achieve the desired creaminess. This French Onion Soup Pasta is now blissfully combined and ready for the next step.
Step 5: Assemble the Dish
Preheat your oven to 350°F (175°C). Transfer the pasta mixture into a greased baking dish, ensuring an even spread. Top it generously with the remaining caramelized onions and sprinkle homemade breadcrumbs over the top for that perfect crunch. This extra layer will provide a delightful contrast to the creamy pasta underneath.
Step 6: Bake for Crispiness
Place the baking dish in the preheated oven and bake uncovered for about 10-15 minutes. Watch as the top turns golden and crispy, signaling that your delicious French Onion Soup Pasta is almost ready. The enticing aroma will fill your kitchen, making it hard to wait!
Step 7: Serve and Garnish
Remove the pasta from the oven and let it sit for a few minutes to set. Just before serving, sprinkle freshly chopped parsley on top for a burst of color and freshness. Now, scoop your creamy, crunchy French Onion Soup Pasta into bowls and enjoy the wonderful flavors of this comforting dish with family and friends.
