How to Make French Onion Soup Pasta Recipe
Step 1: Slice the Onions
Thinly slice the onions into long strips. This step is crucial because it allows the onions to caramelize evenly and develop their natural sweetness as they cook.
Step 2: Caramelize the Onions
Heat a large skillet over medium heat and add olive oil. Sauté the onions for about 30–40 minutes, stirring occasionally. We want them to caramelize slowly until they turn golden brown; this process brings out their rich flavor. If needed, sprinkle in a teaspoon of sugar to help speed up caramelization.
Step 3: Deglaze the Pan
If your onions start sticking to the bottom of the pan, don’t worry! Just add in the beef broth and let it simmer for another 10 minutes. This step not only helps free up those flavorful bits stuck in the pan but also enhances our sauce.
Step 4: Make the Béchamel Sauce
In the same skillet, melt butter over low-medium heat. Whisk in flour and cook for one minute before gradually adding heavy cream. Stir continuously until your sauce thickens—it should be velvety smooth! If you see lumps forming, add ice-cold water and whisk vigorously until they disappear.
Step 5: Combine Flavors
Stir in two-thirds of your beautifully caramelized onions into the béchamel sauce and let everything simmer together. Season with salt, pepper, chopped parsley, and grated Parmesan cheese. This creates layers of flavor that make each bite divine!
Step 6: Cook Your Pasta
While your sauce simmers away, bring a large pot of salted water to boil. Cook your cavatappi macaroni until just shy of al dente—you want them slightly firm as they will continue cooking in the oven.
Step 7: Mix It All Together
Combine your cooked pasta with that luscious béchamel sauce. Stir gently until every piece is coated evenly with that creamy goodness.
Step 8: Prepare for Baking
Transfer your pasta mixture into a baking dish. Top it off with the remaining caramelized onions and sprinkle on some homemade breadcrumbs if you like extra crunch!
Step 9: Bake to Perfection
Bake uncovered at 350°F (175°C) for about 10–15 minutes or until the top is golden brown and crisp. Your kitchen will smell heavenly at this point!
Step 10: Serve & Enjoy!
Once out of the oven, serve immediately while it’s warm and gooey! Every spoonful is bound to bring smiles around your table.
Enjoy making this delightful French Onion Soup Pasta Recipe! It’s sure to become one of your go-to dishes for any occasion!
Pro Tips for Making French Onion Soup Pasta Recipe
Creating this delightful pasta dish is a labor of love, and with a few handy tips, you can elevate your cooking game!
-
Use Sweet Onions: Opt for Vidalia or Walla Walla onions for a naturally sweeter flavor that enhances the caramelization process. This will give a lovely depth to your sauce.
-
Low and Slow Caramelization: Cooking the onions slowly over medium heat allows them to develop their natural sweetness without burning. Patience is key here!
-
Don’t Rush the Béchamel: Gradually adding the heavy cream while whisking ensures a smooth sauce. If it gets lumpy, remember the ice-cold water trick to bring it back to life!
-
Season Generously: Taste as you go! Adjust salt, pepper, and spices throughout the cooking process to create a well-balanced flavor profile that shines.
-
Crispy Topping is Essential: Ensure your breadcrumb topping is generously sprinkled on before baking. This adds texture and an inviting crunch that contrasts beautifully with the creamy pasta.
