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 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 aside the onions.
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. Let the sauce thicken. If your béchamel starts to get lumpy while cooking, add ice-cold water instead of more milk and whisk vigorously until smooth!
Step 5: Combine Onions with Sauce
Stir in ⅔ of the caramelized onions into the béchamel sauce. Season with salt, pepper, chopped parsley, and 1 cup of Parmesan cheese.
Step 6: Cook Pasta
Meanwhile, bring a large pot of salted water to a boil and cook the pasta 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 the béchamel sauce until well mixed.
Step 8: Prepare for Baking
Transfer the pasta mixture to a baking dish. Top with remaining ⅓ of caramelized onions and homemade breadcrumbs.
Step 9: Bake
Bake uncovered at 350°F (175°C) for 10–15 minutes or until golden and crisp on top.
Step 10: Serve
Serve immediately while warm. Enjoy your delicious French Onion Soup Pasta!

Common Mistakes to Avoid
When making the French Onion Soup Pasta Recipe, it’s easy to make a few common mistakes. Here are some pitfalls to watch out for.
- Skipping the caramelization: Not giving onions enough time to caramelize can result in a lack of depth in flavor. Always allow at least 30 minutes for this process.
- Using low-quality cheese: Low-quality cheese won’t melt well and can affect the dish’s creaminess. Always opt for freshly grated Parmesan for the best results.
- Overcooking the pasta: Cooking pasta too long before baking can lead to mushiness. Cook it just shy of al dente since it will continue cooking in the oven.
- Neglecting seasoning: Under-seasoning can make your dish bland. Taste your béchamel sauce and adjust the salt and pepper as needed before mixing with the pasta.
- Not preheating the oven: Baking without preheating can result in uneven cooking. Always preheat your oven to ensure an evenly baked top.
