For the Pasta Base
- 300 g Cavatappi Macaroni

- 3 cups Heavy Cream
- 1 cup Parmesan Cheese (grated)
- 1 tbsp Flour + 3 tbsp water (for béchamel)

How to Make French Onion Soup Pasta Recipe
Step 1: Caramelize the Onions
Thinly slice the onions into long strips. Heat a large skillet over medium heat and add olive oil. Sauté the onions for 30–40 minutes, stirring occasionally until they are golden brown.
Step 2: Add Broth & Seasoning
If the onions begin to stick, add beef broth and let it simmer for an additional 10 minutes. Once caramelized, set aside the onions.
Step 3: Make the Béchamel Sauce
In the same skillet, melt butter over low-medium heat. Whisk in flour and cook briefly before gradually adding heavy cream. Allow it to thicken while whisking continuously.
Step 4: Combine Flavors
Stir in two-thirds of the caramelized onions into the béchamel sauce. Season with salt, pepper, chopped parsley, and Parmesan cheese.
Step 5: Cook the Pasta
Bring a large pot of salted water to boil. Cook cavatappi macaroni until just shy of al dente since it will finish cooking later in the oven.
Step 6: Mix & Transfer
Combine cooked pasta with béchamel sauce until well mixed. Transfer this mixture into a baking dish. Top with remaining caramelized onions and homemade breadcrumbs.
Step 7: Bake
Bake uncovered at 350°F (175°C) for 10–15 minutes or until golden brown on top.
Step 8: Serve
Remove from oven and let cool slightly before serving. Enjoy your delicious French Onion Soup Pasta!

How to Perfect French Onion Soup Pasta Recipe

- Use Quality Broth: Opt for a high-quality beef broth for deeper flavor in your béchamel sauce.
- Monitor Sauce Consistency: Whisk vigorously if lumps form in the béchamel—this keeps the sauce smooth.
- Season Generously: Taste and adjust seasoning throughout the cooking process for balanced flavors.
- Cook Pasta Al Dente: Remember that pasta will continue cooking in the oven; undercook slightly to avoid mushiness.
- Let It Rest: Allow the dish to sit for a few minutes after baking for easier serving.

Common Mistakes to Avoid
When making your French Onion Soup Pasta Recipe, it’s easy to encounter some common pitfalls. Here are a few mistakes to watch out for:
- Overcooking the Onions: Caramelizing onions takes time. If you rush this step, they won’t develop that sweet flavor. Be patient and stir occasionally.
- Using Cold Ingredients for Béchamel: If you add cold ingredients to your béchamel sauce, it may become lumpy. Always start with room temperature ingredients or warm them slightly.
- Cooking Pasta Too Long: Since the pasta will continue cooking in the oven, remove it from boiling water when it’s just shy of al dente. This prevents mushiness.
- Skipping the Seasoning: Proper seasoning is crucial for flavor. Don’t forget to taste your béchamel sauce and adjust salt and pepper as needed.
- Not Using Enough Broth: A little broth helps deglaze the pan while caramelizing onions. It adds depth to your sauce, so don’t skip this step.
