Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize Onions
Slice the onions thinly and heat olive oil in a large skillet over medium heat. Add the onions and cook for 30–40 minutes, stirring occasionally, until they turn golden brown and caramelized. If the onions start to stick, add a splash of beef broth to deglaze the skillet, ensuring that you capture all those lovely, sweet flavors.
Step 2: Make Béchamel Sauce
In the same skillet once the onions are done, melt the butter over medium heat. Whisk in the flour until smooth, then slowly add the heavy cream, stirring continuously until the mixture thickens and bubbles, about 5–7 minutes. Gently fold in the caramelized onions, season with salt and pepper, and mix in the Parmesan cheese until melted and creamy.
Step 3: Cook Pasta
Bring a large pot of salted water to a boil. Add the cavatappi macaroni and cook until it’s al dente, about 1–2 minutes shy of package instructions. Drain the pasta and reserve a cup of the pasta water—this will help adjust the sauce later if needed. Set the drained pasta aside while you prepare for baking.
Step 4: Combine and Bake
Preheat your oven to 350°F (175°C). In a large bowl, mix the cooked pasta with the béchamel sauce until well combined. Transfer the creamy pasta mixture to an oven-safe baking dish. Evenly spread the remaining caramelized onions on top, and generously sprinkle with breadcrumbs for added crunch.
Step 5: Bake Until Golden
Place the baking dish in the preheated oven and bake for 10–15 minutes, or until the top is golden brown and the edges are bubbling. Keep an eye on it to achieve that perfect crispy topping without burning. This step transforms your French onion soup pasta into a delightful, comforting casserole.
Step 6: Serve and Garnish
Once out of the oven, let the dish cool for a couple of minutes. Garnish with freshly chopped parsley for a pop of color and a hint of freshness. Scoop out servings of your delicious French Onion Soup Pasta and dive into the creamy, savory layers complemented by that wonderful crunch.

Expert Tips for French Onion Soup Pasta
Onion Caramelization: Ensure onions are cooked slowly over medium heat for optimal sweetness and depth of flavor; rushing this step can lead to bitterness.
Whisk Diligently: When making the béchamel sauce, whisk vigorously to avoid lumps; adding ice-cold water can help if it thickens too quickly.
Pasta Cooking: Cook the pasta just shy of al dente, as it will continue cooking in the oven. This prevents overcooking and maintains the perfect texture.
Use Quality Ingredients: Freshly grated Parmesan cheese and high-quality broth enhance the overall taste of your French Onion Soup Pasta, making it truly irresistible.
Keep an Eye on Baking: Watch the dish while it’s in the oven. The optimal baking time should make the topping golden brown without burning it.
Garnish for Freshness: A sprinkle of fresh parsley just before serving adds a burst of color and brightness, enhancing both presentation and flavor.
