How to Make French Onion Soup Pasta Recipe
Step 1: Prepare the Onions
Thinly slice the onions into long strips. The key here is patience—caramelizing onions takes time but brings out their natural sweetness. Heat a large skillet over medium heat and add olive oil. Sauté the onions for 30–40 minutes, stirring occasionally. Allow them to caramelize slowly without burning. If you want, add a teaspoon of sugar to speed up the process!
Step 2: Create the Béchamel Sauce
Once your onions are beautifully caramelized, set them aside and prepare your béchamel sauce in the same skillet. Melt butter over low-medium heat, whisk in flour, and cook for just a minute before gradually adding heavy cream. This step is crucial; letting your sauce thicken will ensure that your pasta has that creamy texture we all love.
Step 3: Combine Everything
Stir in two-thirds of the caramelized onions into your béchamel sauce and let it simmer while seasoning with salt, pepper, chopped parsley, and grated Parmesan cheese. Meanwhile, bring a pot of salted water to boil and cook your cavatappi macaroni until just shy of al dente—this ensures that they won’t become mushy in the oven.
Step 4: Bake Your Dish
Combine the cooked pasta with your béchamel sauce until everything is well mixed together. Transfer this delicious mixture into a baking dish, topping it with the remaining caramelized onions and homemade breadcrumbs. Bake uncovered at 350°F (175°C) for 10–15 minutes until golden brown on top.
Step 5: Serve & Enjoy!
Once it’s baked to perfection, serve immediately! A sprinkle of fresh parsley on top makes it look as good as it tastes. Enjoy every comforting bite of this French Onion Soup Pasta Recipe—it’s sure to be a new favorite!
Pro Tips for Making French Onion Soup Pasta Recipe
Creating the perfect French Onion Soup Pasta is all about the details, so here are some handy tips to help you achieve a delicious result!
-
Slow and Steady Caramelization: Allow your onions to cook slowly over medium heat to develop their natural sweetness and rich flavor. Rushed cooking can lead to burnt bits instead of that beautiful golden-brown color.
-
Béchamel Consistency Check: Ensure your béchamel sauce is smooth by whisking vigorously and adjusting with ice-cold water if it gets lumpy. This technique prevents a gritty texture in your final dish, keeping it creamy and delightful.
-
Cheese Choice Matters: While Parmesan is the traditional choice, feel free to mix in other cheeses like Gruyère or mozzarella for added flavor and creaminess. This can enhance the taste profile and make your pasta even more indulgent.
-
Pasta Precooking Tip: Cooking your pasta just shy of al dente is crucial since it will finish cooking in the oven. This way, you’ll avoid mushy pasta and ensure a perfect texture after baking.
-
Breadcrumb Crunch: For an extra crispy topping, consider adding a sprinkle of nutritional yeast or garlic powder to your breadcrumbs before baking. This not only adds flavor but also increases the crunch factor for a delightful contrast in textures.
