How to Make French Onion Soup Pasta Recipe
Step 1: Slice the Onions
Thinly slice the onions into long strips.
Step 2: Caramelize the Onions
Heat a large skillet or pan over medium heat and add olive oil. Sauté the onions for 30–40 minutes, stirring occasionally. Allow them to caramelize slowly without burning. You can add 1 teaspoon of sugar to speed up caramelization if desired.
Step 3: Add Beef Broth
If the onions begin to stick to the bottom of the pan, add in the beef broth and let it simmer for another 10 minutes. Once caramelized, set the onions aside while preparing the béchamel sauce.
Step 4: Prepare Béchamel Sauce
In the same skillet, melt butter over low-medium heat. Whisk in flour and cook for about a minute before gradually adding heavy cream. Let the sauce thicken. If lumps form while cooking, add ice-cold water instead of more milk and whisk vigorously until smooth.
Step 5: Combine Ingredients
Stir in ⅔ of the caramelized onions into your béchamel sauce and let it simmer. Season with salt, pepper, chopped parsley, and stir in 1 cup of Parmesan cheese.
Step 6: Cook Pasta
Meanwhile, bring a large pot of salted water to boil and cook cavatappi macaroni until just shy of al dente since it will finish cooking in the oven.
Step 7: Mix Pasta with Sauce
Combine the cooked pasta with your béchamel sauce ensuring everything is mixed well.
Step 8: Assemble Dish
Transfer the pasta mixture into a baking dish. Top with remaining ⅓ of caramelized onions and sprinkle homemade breadcrumbs on top.
Step 9: Bake
Bake uncovered at 350°F (175°C) for about 10–15 minutes or until the top is golden brown and crisp.
Step 10: Serve
Serve immediately while hot and enjoy this delightful French Onion Soup Pasta!

How to Perfect French Onion Soup Pasta Recipe
To make your French Onion Soup Pasta truly exceptional, consider these helpful tips:
-
Use Quality Onions: Sweet onions like Vidalia or Walla Walla enhance the caramelization process, bringing out deep flavors.
-
Don’t Rush Caramelization: Allow onions to cook slowly for 30–40 minutes. This step is crucial for achieving that sweet, golden color.
-
Cook Pasta Al Dente: Since it will bake later, ensure your pasta is slightly undercooked. This prevents it from becoming mushy during baking.
-
Experiment with Cheeses: While Parmesan is traditional, trying Gruyère or Fontina can add depth and richness to your dish.
-
Adjust Seasonings: Taste your sauce and adjust salt and pepper levels as needed to suit your palate.

Common Mistakes to Avoid
When preparing your French Onion Soup Pasta Recipe, be aware of common pitfalls that could affect the dish’s flavor and texture.
- Incorrect Onion Preparation: Slicing onions too thickly can prevent proper caramelization. Always aim for thin, even slices to achieve that sweet, caramelized flavor.
- Overcooking the Pasta: Cooking the pasta beyond al dente will result in mushy noodles after baking. Remember, it should be slightly undercooked since it will continue to cook in the oven.
- Neglecting Seasoning: Failing to properly season your sauce can lead to bland pasta. Taste as you go and adjust salt, pepper, and herbs accordingly for a flavorful dish.
- Skipping the Breadcrumb Topping: The crispy breadcrumb topping adds essential texture. Don’t skip this step; it enhances both presentation and flavor.
- Rushing Caramelization: Cooking onions too quickly leads to uneven color and taste. Patience is key—allow them to caramelize slowly for better results.
