Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize the Onions
Begin by thinly slicing 5 onions, then heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions to the skillet, and sauté them for 30-40 minutes, stirring occasionally until they turn a deep golden brown. If desired, sprinkle in 1 teaspoon of sugar to enhance sweetness and help the caramelization process. For any sticking, periodically deglaze the pan with a splash of beef broth.
Step 2: Prepare the Béchamel Sauce
Once the onions are beautifully caramelized, lower the heat and in the same skillet, melt 2 tablespoons of butter. Whisk in 1 tablespoon of flour, cooking for about 1 minute until the mixture is golden. Gradually pour in 1 cup of heavy cream, stirring continuously until the sauce thickens, which should take around 5 minutes. Stir in ⅔ of the caramelized onions, season with salt, pepper, parsley, and ½ cup of grated Parmesan cheese for a creamy béchamel.
Step 3: Cook the Pasta
In a large pot, bring salted water to a boil. Add 300g of cavatappi macaroni and cook until just under al dente, about 1-2 minutes less than package directions suggest, as it will continue to cook in the oven. Drain the pasta and return it to the pot, then add the béchamel sauce. Mix thoroughly until every piece of pasta is coated in that rich, creamy goodness.
Step 4: Combine and Bake
Transfer the pasta mixture into a greased baking dish. Spread the remaining caramelized onions on top, and add a generous layer of homemade breadcrumbs made from 1 baguette tossed in olive oil. Preheat your oven to 350°F (175°C), and bake the dish uncovered for 10-15 minutes, until the top is golden brown and crispy.
Step 5: Serve and Enjoy
Remove the French onion soup pasta from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley for a pop of color and flavor. Serve immediately so that you can enjoy the delightful contrast of the creamy pasta and crispy topping.
