How to Make French Onion Soup Pasta Recipe
Step 1: Prepare the Onions
Start by thinly slicing the onions into long strips. Heating them slowly over medium heat allows their natural sweetness to develop. Remember, patience is key here; letting them caramelize properly brings out their rich flavor!
Step 2: Caramelize the Onions
In a large skillet, add olive oil and sauté the onions for 30–40 minutes. Stir occasionally and let them become golden brown. If they start sticking to the pan, add in some beef broth—this will help lift those delicious bits off the bottom!
Step 3: Make the Béchamel Sauce
In the same skillet, melt butter over low-medium heat (you can use plant-based butter if preferred). Whisk in flour until smooth before gradually adding heavy cream. This creates your luscious béchamel sauce. If lumps form, don’t worry—just whisk vigorously with ice-cold water until smooth!
Step 4: Combine Flavors
Stir in two-thirds of those beautifully caramelized onions into your béchamel sauce. Season generously with salt, pepper, chopped parsley, and most importantly—Parmesan cheese! Let everything simmer together so those flavors meld beautifully.
Step 5: Cook Your Pasta
Meanwhile, boil a large pot of salted water and cook your cavatappi until it’s just shy of al dente. This ensures it finishes cooking perfectly when baked later.
Step 6: Bring It All Together
Combine your cooked pasta with that creamy béchamel sauce. Give it a good stir until every piece is coated in deliciousness!
Step 7: Transfer and Top
Pour your pasta mixture into a baking dish. Top it off with the remaining caramelized onions and sprinkle on some homemade breadcrumbs for that irresistible crunch.
Step 8: Bake Until Golden
Bake uncovered at 350°F (175°C) for about 10–15 minutes until the top is golden brown and crispy.
Step 9: Serve and Enjoy!
Serve immediately while it’s hot. Trust me; everyone will be asking for seconds! Enjoy this comforting dish filled with love and flavor!
Pro Tips for Making French Onion Soup Pasta Recipe
Cooking can be an adventure, and with these pro tips, you’ll ensure your French Onion Soup Pasta turns out perfectly every time!
-
Choose the right onions: Using sweet onions like Vidalia or Walla Walla enhances the sweetness of the caramelization process, giving your pasta a rich flavor.
-
Patience is key in caramelization: Letting the onions cook slowly over medium heat allows their natural sugars to develop, creating that deep, delicious flavor. Don’t rush this step!
-
Make it creamy with cold water: If your béchamel sauce starts getting lumpy, adding ice-cold water instead of more cream can help bring it back to a smooth consistency without compromising richness.
-
Don’t overcook the pasta: Cooking the pasta just shy of al dente ensures that it won’t become mushy when baked. This also allows it to absorb the flavors of the sauce beautifully.
-
Experiment with cheeses: While Parmesan adds a wonderful depth, try mixing in some Gruyère or mozzarella for extra creaminess and flavor variation.
