Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize the Onions
Thinly slice the yellow onions and heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions, a pinch of salt, and optional sugar, stirring occasionally for about 30–40 minutes. Cook until they turn golden brown and are deeply caramelized, ensuring to scrape up any fond that forms on the skillet. If they begin to stick, splash in a bit of beef broth to keep them moist.
Step 2: Prepare the Béchamel Sauce
In the same skillet with the caramelized onions, add 4 tablespoons of butter over low heat. Once melted, whisk in ¼ cup of flour, creating a roux, and cook for about 2 minutes. Gradually pour in 2 cups of heavy cream while whisking continuously to avoid lumps. Once thickened, incorporate ⅔ of the caramelized onions, sprinkle in a pinch of nutmeg, and season with salt and fresh ground pepper.
Step 3: Cook the Pasta
In a separate pot, bring a large pot of salted water to a boil. Add 8 ounces of cavatappi macaroni and cook until al dente, about 2 minutes shy of the package instructions. Reserve ½ cup of the starchy pasta water, then drain the pasta. This pasta will be combined with the béchamel sauce, so ensure not to overcook it for the best texture.
Step 4: Combine the Pasta and Sauce
Return the drained pasta to the pot and pour in the creamy béchamel sauce. Mix well to coat the pasta evenly, adding in the reserved pasta water a little at a time if it feels too thick. This creamy French Onion Soup Pasta should be beautifully creamy and well combined before transferring it to a baking dish.
Step 5: Assemble and Prepare for Baking
Preheat your oven to 350°F (175°C). Transfer the pasta mixture into a greased baking dish, spreading it out evenly. Top with the remaining caramelized onions and a generous sprinkle of breadcrumbs mixed with ⅓ cup of grated Parmesan cheese. This will create a delicious crispy topping as it bakes.
Step 6: Bake Until Golden
Place the baking dish in the preheated oven and bake for 10–15 minutes. Keep an eye on it until the top turns golden brown and the breadcrumbs are crisp. The aroma of the French Onion Soup Pasta will fill your kitchen, signaling it’s almost ready to be enjoyed.
Step 7: Serve and Garnish
Once out of the oven, let the dish cool slightly for about 5 minutes. Serve hot, garnished with fresh parsley for a pop of color and freshness if desired. Enjoy the comforting flavors of your creamy French Onion Soup Pasta, perfect for a cozy meal or impressing guests!
Make Ahead Options
These creamy French Onion Soup Pasta are perfect for busy weeknights or meal prep enthusiasts! You can prepare the entire dish up to 24 hours in advance by following a few simple steps. Cook the pasta and make the béchamel sauce, then combine them with the caramelized onions before transferring everything into a baking dish. Cover tightly with plastic wrap and refrigerate. To maintain quality, store the topping separately; add the breadcrumbs and remaining onions right before baking to ensure they stay crispy. When you’re ready to serve, just pop it in the oven at 350°F (175°C) for about 10–15 minutes until golden and bubbly—resulting in just as delicious a meal with minimal effort.

Expert Tips for French Onion Soup Pasta
- Caramelization Secrets: For perfectly caramelized onions, stir occasionally and add a pinch of sugar to enhance sweetness and prevent sticking.
- Creamy Consistency: If your béchamel sauce becomes lumpy, whisk in some ice-cold water to restore smoothness and achieve the desired creamy texture.
- Cook Pasta Al Dente: Avoid mushy pasta by cooking it just short of al dente. It will continue to soften during baking while perfectly coating in the béchamel sauce.
- Even Top Crunch: Ensure even crispness by spreading breadcrumbs evenly over your assembled dish; mix with cheese for added flavor and texture.
- Reheat with Care: To preserve the crunchy topping, reheat your French onion soup pasta in the oven instead of the microwave, keeping it crispy and delightful.
French Onion Soup Pasta Recipe FAQs
How do I choose the right onions for this recipe?
Absolutely! I recommend using yellow onions for this creamy French Onion Soup Pasta as they have the natural sweetness and flavor depth that complements the dish beautifully. Avoid using overly soft or sprouted onions; firm ones with minimal dark spots are best.
What’s the best way to store leftovers?
Very simple! Store your delicious French Onion Soup Pasta in an airtight container in the fridge for 3-4 days. When ready to enjoy, reheat it in the oven at 350°F (175°C) for about 15-20 minutes until hot and the crispy topping is restored.
Can I freeze this dish?
Definitely! To freeze, let the pasta cool completely before transferring it into a sealed container or freezer-safe bag. It can be frozen for up to 2 months. When you’re ready to eat, thaw it overnight in the fridge, then reheat in the oven for about 20-25 minutes at 350°F (175°C).
What if my béchamel sauce is lumpy?
No worries! If you find that your béchamel sauce has lumps, simply whisk in a few tablespoons of ice-cold water, and continue whisking vigorously over low heat until the sauce becomes smooth and creamy.
Can I make this dish vegetarian?
Absolutely! To create a vegetarian version of this comforting dish, swap the beef broth for vegetable broth and use nutritional yeast instead of Parmesan cheese. This way, you can still enjoy the rich flavors without any meat products.
Are there any allergens I should be aware of?
Great question! The French Onion Soup Pasta contains common allergens such as dairy (cream and cheese) and gluten (in flour and pasta). For gluten-free options, substitute the regular pasta and flour with gluten-free alternatives. If you or your guests have dairy allergies, I often use coconut milk and nutritional yeast to create a delicious dairy-free version.
