How to Make French Onion Soup Pasta Recipe
Step 1: Prepare the Onions
Thinly slice the onions into long strips. This step is crucial as it gives them enough surface area to caramelize beautifully. Heat a large skillet over medium heat and add olive oil. Sauté the onions gently for 30–40 minutes, stirring occasionally. You want those onions to turn golden brown and sweet—trust me; this is where all the magic happens!
Step 2: Caramelize the Onions
If your onions begin to stick to the pan, don’t worry! Just add in some beef broth and let it simmer for another 10 minutes. Once they are perfectly caramelized, set them aside while you prepare the béchamel sauce.
Step 3: Make the Béchamel Sauce
In the same skillet, melt butter over low-medium heat (feel free to substitute with vegan butter if desired). Whisk in flour and cook for about a minute before gradually adding heavy cream. Keep stirring until it thickens! If necessary, add ice-cold water if lumps form—this will help smooth out your sauce quickly.
Step 4: Combine Ingredients
Stir in two-thirds of your caramelized onions into the béchamel sauce and let it simmer gently. Season with salt, pepper, chopped parsley, and stir in one cup of grated Parmesan cheese until smooth and creamy.
Step 5: Cook Your Pasta
Meanwhile, bring a large pot of salted water to boil and cook your cavatappi macaroni until just shy of al dente—it will finish cooking in the oven later!
Step 6: Mix It All Together
Combine your cooked pasta with that luscious béchamel sauce until everything is well coated. The creamy goodness should envelop each piece of pasta; it’s simply divine!
Step 7: Bake Your Dish
Transfer everything into a baking dish. Top with remaining caramelized onions and sprinkle on those homemade breadcrumbs from your baguette. Bake uncovered at 350°F (175°C) for about 10–15 minutes until golden brown on top.
Step 8: Serve & Enjoy!
Once baked to perfection, serve immediately while still warm. I promise you’ll want seconds—not just because it’s delicious but because it feels like home! Enjoy every mouthful!
Pro Tips for Making French Onion Soup Pasta Recipe
Creating the perfect French Onion Soup Pasta is all about technique and love, so here are some pro tips to help you shine in the kitchen!
-
Caramelize Slowly: Take your time with the onions. The longer they cook, the sweeter and more flavorful they become. Rushing this step can lead to burnt pieces rather than beautiful, golden caramelization.
-
Use Fresh Herbs: Fresh parsley not only brightens up the dish but also adds a burst of freshness that complements the rich flavors. It’s a small touch that makes a big difference!
-
Adjust Consistency: If your béchamel sauce is too thick, add a splash of broth or water to loosen it up. This ensures that every bite of pasta is creamy and delicious without being overly heavy.
-
Mix Cheese Wisely: Reserve some cheese for topping! Mixing cheese into the sauce provides flavor throughout, while adding more on top creates that irresistible cheesy crust when baked.
-
Don’t Overcook Pasta: Since the pasta will finish cooking in the oven, aim for al dente when boiling. This prevents mushy pasta and keeps a nice bite in your dish.

Serving this delightful dish can elevate your dining experience! Here are some ideas on how to present it beautifully, making every meal feel special.

- Grated Parmesan: Adding extra grated Parmesan right before serving enhances the cheesy goodness and gives an appealing finish.
Side Dishes
- Garlic Bread: Crunchy and buttery garlic bread pairs perfectly with this creamy pasta, providing a delightful texture and taste contrast.
- Mixed Green Salad: A simple salad with mixed greens dressed in a light vinaigrette balances out the richness of the pasta nicely, adding freshness to your plate.
- Roasted Vegetables: Seasonal roasted veggies like zucchini and bell peppers add vibrant colors and flavors, making your meal more wholesome.
- Steamed Asparagus: Lightly steamed asparagus drizzled with lemon juice offers a refreshing side that complements the savory notes of the main dish beautifully.
