Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize the Onions
Thinly slice the onions and heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions and sauté them slowly for 30–40 minutes, stirring occasionally, until they turn a rich, golden brown. If the onions start to stick, add a splash of beef broth to deglaze the pan, ensuring their sweet flavors develop beautifully.
Step 2: Prepare the Béchamel Sauce
In the same skillet, reduce the heat slightly and add 4 tablespoons of butter. Once melted, whisk in ¼ cup of flour to form a roux, cooking for about 2 minutes. Gradually pour in 2 cups of heavy cream, stirring continuously until the mixture thickens. Stir in two-thirds of your caramelized onions, along with salt, pepper, parsley, and Parmesan cheese to create a creamy base for your French Onion Soup Pasta.
Step 3: Cook the Pasta
Bring a large pot of salted water to a boil. Add 12 ounces of cavatappi macaroni and cook it according to package instructions until just under al dente, usually around 7-9 minutes. Make sure to reserve about 1 cup of pasta water before draining, as it can help adjust the sauce’s consistency later if needed.
Step 4: Combine Pasta and Sauce
Once the pasta is cooked and drained, return it to the pot and pour the béchamel sauce over the top. Gently toss everything together, ensuring the pasta is well-coated. If the mixture seems too thick, incorporate some reserved pasta water until you reach a creamy consistency. This delicious blend is the heart of your French Onion Soup Pasta.
Step 5: Assemble and Bake
Preheat your oven to 350°F (175°C). Transfer the pasta mixture to a greased baking dish. Top with the remaining caramelized onions and sprinkle an even layer of breadcrumbs over the top for added crunch. Bake for 10-15 minutes, or until the breadcrumbs are golden brown and crisp, providing a delightful contrast to the creamy pasta underneath.
Step 6: Serve and Enjoy
Once baked, remove your French Onion Soup Pasta from the oven and let it cool for a few minutes before serving. Garnish with freshly chopped parsley for a vibrant touch. Divvy it up onto plates or serve it family-style, and delight in the comforting, rich flavors that make this dish truly special!

Tips for the Best French Onion Soup Pasta
• Perfectly Caramelized Onions: Take your time! Slow-cooking onions on medium heat develops their sweetness, creating deeper flavors essential for your French Onion Soup Pasta.
• Smooth Béchamel: If your béchamel sauce gets lumpy, whisk it vigorously and add a splash of cold water to return it to silky perfection.
• Pasta Timing: Cook the pasta just under al dente, as it will continue to cook in the oven. This step ensures the perfect texture for your dish.
• Bread Crumb Crunch: For extra flavor, mix herbs or garlic powder into your breadcrumbs before topping. This adds another layer of deliciousness and enhances the whole meal.
• Customizable Options: Don’t hesitate to swap ingredients based on dietary preferences. Vegan cream and vegetable broth allow this dish to cater to everyone without sacrificing taste.
Make Ahead Options
Preparing your creamy French Onion Soup Pasta in advance is a fantastic way to save time during busy weeknights! You can caramelize the onions up to 3 days ahead—just store them in an airtight container in the refrigerator. Additionally, the béchamel sauce can be made up to 24 hours ahead; simply keep it covered in the fridge to maintain its creamy texture. When you’re ready to enjoy, cook your pasta and combine it with the chilled sauce and onions. Then, bake as directed for that delightful finish. This method ensures the dish is just as delicious while allowing you to spend more time with your loved ones at mealtime!

Creamy French Onion Soup Pasta Recipe FAQs
How do I choose the right onions for caramelizing?
Absolutely! For the best caramelization, I recommend using yellow onions. They have a natural sweetness that develops beautifully when cooked slowly. Avoid using white onions, as they can be sharper in flavor, and red onions, which don’t caramelize quite the same way.
How should I store leftovers of French Onion Soup Pasta?
Very easy! Store leftover French Onion Soup Pasta in an airtight container in the refrigerator for up to 3-4 days. Ensure it’s cooled before sealing to prevent moisture buildup, which can make the pasta soggy.
Can I freeze French Onion Soup Pasta?
Absolutely! To freeze, place the pasta in an airtight container or a freezer-safe bag for up to 2 months. For best results, wrap the dish tightly in plastic wrap before sealing to prevent freezer burn.
What should I do if my béchamel sauce turns lumpy?
If your béchamel sauce gets lumpy, don’t worry! Simply whisk it vigorously over low heat and add a splash of ice-cold water. This should smooth it out again. Making sure to stir continuously while adding cream will also help create a silky texture.
Are there vegan alternatives for this recipe?
Yes, absolutely! You can easily make this dish vegan by swapping out the beef broth for vegetable broth and using coconut milk or a dairy-free cream alternative instead of heavy cream. Nutritional yeast can replace Parmesan cheese for a cheesy flavor without the dairy.
How do I know when the onions are perfectly caramelized?
Great question! You’ll know the onions are ready when they turn a lovely golden brown color, taking about 30-40 minutes over medium heat, stirring occasionally. Watch for that rich, sweet aroma! If they start to stick, simply add a splash of broth to deglaze your pan.
