French Onion Soup Pasta Ingredients
-
For the Pasta
• Cavatappi Macaroni – This pasta shape holds the creamy béchamel beautifully; avoid long shapes that may not mix well.
• Salt – Essential for seasoning; use sea salt or kosher salt for better control. -
For the Sauce
• Olive Oil – Ensures rich flavor for sautéed onions; feel free to substitute with any cooking oil you prefer.
• Onions – The heart of this dish, caramelizing them adds sweetness; shallots can be used for a milder flavor.
• Beef Broth – Enhances the depth of flavor; for a vegetarian option, use vegetable broth instead.
• Heavy Cream – Creates a rich, luxurious béchamel; you can swap this for coconut milk or non-dairy cream for a lighter version.
• Flour – Thickens the béchamel sauce to perfection; consider cornstarch for a gluten-free alternative if needed.
• Parmesan Cheese – Adds creaminess and depth; nutritional yeast works as a tasty dairy-free substitute.
• Garlic Powder – Amplifies the flavor profile; opt for fresh garlic for a more intense taste if desired.
• Nutmeg – A pinch elevates the flavors; be careful not to overdo it!

Step‑by‑Step Instructions for Creamy French Onion Soup Pasta Recipe
Step 1: Caramelize the Onions
Thinly slice two large onions and heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions and a pinch of salt, stirring occasionally for 30-40 minutes. Cook them until they become deep golden brown and sweetly fragrant—this slow caramelization is key to achieving rich flavor for your French Onion Soup Pasta.
Step 2: Prepare the Béchamel Sauce
Once the onions are nicely caramelized, push them to one side of the skillet and melt 2-3 tablespoons of butter in the empty side. Whisk in 2 tablespoons of flour and stir for about a minute, then gradually pour in 1 cup of heavy cream while whisking continuously, preventing lumps. Cook until the sauce thickens and bubbles gently—this luscious consistency will elevate your creamy pasta.
Step 3: Combine Ingredients
Stir two-thirds of the caramelized onions into the béchamel sauce, followed by 1 cup of grated Parmesan cheese, 1 teaspoon of oregano, and salt and pepper to taste. Mix well until all ingredients are well incorporated, enhancing the flavors of your creamy French Onion Soup Pasta.
Step 4: Cook the Pasta
In a large pot, bring salted water to a boil, then add 8 ounces of cavatappi macaroni. Cook the pasta according to package instructions until al dente, typically around 8-10 minutes. Drain well when done, and reserve about 1/2 cup of pasta cooking water to adjust the sauce if it’s too thick.
Step 5: Mix and Bake
Combine the cooked pasta with the béchamel sauce in the skillet, adding a splash of the reserved pasta water if needed for creaminess. Transfer the mixture to a greased baking dish, then top with the remaining caramelized onions and a generous layer of breadcrumbs. Bake at 350°F (175°C) for 10-15 minutes until the top is golden and bubbling—creating a delightful crunch that complements the creamy texture of your pasta.

French Onion Soup Pasta Recipe FAQs
How do I choose the best onions for this recipe?
Absolutely! For deep flavor, opt for yellow onions as they caramelize beautifully. If you prefer a milder taste, shallots are a wonderful alternative. Look for onions that are firm and free from dark spots or soft areas. Freshness enhances sweetness, which is key to this creamy dish.
How should I store leftovers of the French Onion Soup Pasta?
I recommend storing leftovers in an airtight container in the fridge for up to 3-4 days. If you prefer to keep it longer, you can freeze individual portions in freezer-safe bags or containers for up to 2 months. Just label your containers with the date so you can enjoy them later!
Can I freeze this pasta dish?
Certainly! To freeze, allow the pasta to cool completely. Then, transfer it to airtight containers or heavy-duty freezer bags. Lay flat to save space in the freezer. When you’re ready to enjoy it, thaw overnight in the fridge and reheat in the oven covered at 350°F (175°C) for about 20 minutes, uncovering for the last 5 minutes to restore that delightful crunch.
What can I do if my béchamel sauce turns lumpy?
No need to worry! If your béchamel thickens unexpectedly and becomes lumpy, here’s what you can do: Add a splash of cold water and whisk vigorously until the lumps break apart. If needed, you can repeat this process to achieve a smooth consistency. Keep whisking until it’s creamy and velvety!
Are there any dietary considerations for this dish?
Very much! This Creamy French Onion Soup Pasta can easily be adapted for various dietary needs. Swap heavy cream for coconut or almond milk to make it dairy-free, and use gluten-free pasta to cater to gluten sensitivities. Always check the cheese for vegetarian options if you’re avoiding animal rennet. Plus, this dish can be a great source for vegetarian protein if you want to throw in some cooked lentils or chickpeas!
Can I use store-bought breadcrumbs instead of homemade?
Of course! If you’re in a pinch, store-bought breadcrumbs work perfectly. However, I often toast them in a skillet with a bit of olive oil for that added crunch and flavor. It’s a simple step that makes a big difference in elevating your French Onion Soup Pasta dish!
