Step‑by‑Step Instructions for French Onion Soup Pasta Recipe
Step 1: Caramelize Onions
Begin by thinly slicing your onions and then heat a generous splash of olive oil in a large skillet over medium heat. Add the onions, cooking them for 30–40 minutes, stirring occasionally until they turn a deep golden color and become sweetly aromatic. If they begin to stick to the pan, add a splash of beef broth and let them simmer for an additional 10 minutes to continue the caramelization process.
Step 2: Prepare Béchamel Sauce
In the same skillet, lower the heat slightly and add butter, allowing it to melt before whisking in flour. Cook the mixture for about 1 minute, stirring constantly to create a roux. Gradually pour in the heavy cream while whisking vigorously to avoid lumps, continuing to heat until the sauce thickens to a creamy consistency that coats the back of a spoon, roughly 2–3 minutes.
Step 3: Combine Ingredients
To the velvety béchamel sauce, stir in about two-thirds of your beautifully caramelized onions. Season the mixture generously with salt, pepper, chopped fresh parsley, and grated Parmesan cheese to infuse your French Onion Soup Pasta with rich flavors. Mix well until all ingredients are combined, ensuring the cheese is melted into the sauce for extra creaminess.
Step 4: Cook Pasta
Bring a large pot of salted water to a boil, then add the cavatappi macaroni. Cook the pasta until it is just under al dente, typically about 2 minutes less than the package instructions suggest, since it will finish cooking in the oven. Drain the pasta and reserve a cup of the cooking water to make adjustments to the final sauce, if needed.
Step 5: Mix and Transfer
Gently fold the cooked pasta into the béchamel sauce, ensuring each piece is well-coated. If the mixture seems too thick, add a little of the reserved pasta water to loosen it. Transfer this creamy pasta mixture into an oven-safe dish, and top it with the remaining caramelized onions and a sprinkling of freshly made breadcrumbs for that delightful crunch.
Step 6: Bake
Preheat your oven to 350°F (175°C) and place your dish in the oven for 10-15 minutes, or until the top is gloriously golden brown and crispy. Keep an eye on it to avoid burning; once the breadcrumbs have crisped up, remove from the oven and allow to cool slightly before serving your delicious French Onion Soup Pasta while hot for that ultimate comforting experience.

Storage Tips for French Onion Soup Pasta
Fridge: Store leftovers in an airtight container for up to 3-4 days. This will keep the flavors fresh and maintain the creamy texture.
Freezer: For longer storage, freeze the French onion soup pasta in a freezer-safe container for up to 2 months. Thaw in the fridge overnight before reheating.
Reheating: Reheat in the oven at 350°F (175°C) for 10-15 minutes until warmed through. Alternatively, use a skillet with a splash of cream or water for a stovetop option.
Wrapping: If using a baking dish, cover it with foil to prevent drying out while reheating. This ensures your pasta retains its delicious, creamy goodness!
Make Ahead Options
These French Onion Soup Pasta recipes are fantastic for meal prep aficionados!
