How to Make French Onion Soup Pasta
- Caramelize the Onions: Slice onions thinly and heat olive oil in a skillet over medium heat. Add onions and a sprinkle of salt. Sauté them for 30-40 minutes until they turn golden brown, stirring occasionally. If they stick, deglaze with beef broth.
- Prepare the Béchamel Sauce: In the same skillet, melt butter over low heat. Whisk in flour, cooking for a minute. Gradually pour in heavy cream, whisking to avoid lumps. Stir in ⅔ of the caramelized onions, seasoning with salt, pepper, and parsley, then mix in Parmesan cheese.
- Cook the Pasta: Boil salted water in a large pot, add cavatappi pasta, and cook until just under al dente (about 1-2 minutes less than package instructions). Don’t forget to reserve some pasta water before draining it!
- Combine: In the skillet with the béchamel sauce, gently fold in the cooked pasta. Adjust the consistency using reserved pasta water—aim for a creamy texture that clings to the pasta beautifully.
- Assemble and Bake: Preheat your oven to 350°F (175°C). Transfer the mixture to a greased baking dish. Top with the remaining onions and breadcrumbs. Bake for 10-15 minutes until the topping is golden and crispy.
- Serve: Allow the dish to sit for a few minutes before serving. Garnish with fresh parsley, and enjoy with a vibrant side salad or crusty bread.
Optional: Sprinkle with extra cheese before baking for a richer flavor.
