Dive into preparing this French Onion Soup Pasta and watch as it transforms your kitchen into a comforting haven! Step‑by‑Step Instructions for French Onion Soup Pasta Step 1: Caramelize the Onions Begin by thinly slicing the five onions. In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the onions along with a pinch of salt, and sauté them for 30–40 minutes, stirring occasionally. You want them to turn a deep golden-brown color, signaling that they are perfectly caramelized. If they start to stick, add a splash of beef broth to keep them moist. Step 2: Make the Béchamel Sauce In the same skillet with the caramelized onions, melt 2 tablespoons of butter over medium-low heat. Gradually whisk in 3 tablespoons of flour until it forms a paste, cooking for about 1 minute. Slowly pour in 1 cup of heavy cream while whisking continuously. Cook until the sauce thickens, usually around 5 minutes. Stir in two-thirds of the caramelized onions, salt, pepper, oregano, and ½ cup of grated Parmesan cheese until well combined. Step 3: Cook the Pasta In a large pot, bring 4 quarts of salted water to a boil. Add 12 ounces of cavatappi macaroni and cook it until just under al dente, about 7–8 minutes. Drain the pasta, reserving a cup of the pasta water, and then return it to the pot. This will ensure your pasta maintains its structure and doesn’t get mushy when mixed with the sauce. Step 4: Combine and Bake Preheat the oven to 350°F (175°C). Pour the béchamel sauce with onions over the drained pasta and mix gently until well coated. Transfer the mixture to a greased baking dish, spreading it evenly. Top with the remaining caramelized onions and sprinkle generously with homemade or store-bought breadcrumbs for that delightful crunch. Step 5: Bake the Dish Place the baking dish in the preheated oven and bake for 10-15 minutes. You’re looking for a golden brown top with crispy breadcrumbs. The edges should be bubbling, indicating the creamy goodness within is perfectly melded. Step 6: Serve and Enjoy Once baked, remove the dish from the oven and let it cool for a few minutes. Garnish with fresh parsley for a pop of color, and serve your luscious French Onion Soup Pasta warm. This dish shines when paired with a fresh green salad or crusty bread for a complete meal. Storage Tips for French Onion Soup Pasta Fridge: Store leftover French Onion Soup Pasta in an airtight container for up to 3-4 days. Reheat gently on the stovetop or in the microwave, adding a splash of broth or cream to restore creaminess. Freezer: For longer storage, freeze the dish for up to 2 months. Cool completely before transferring to a freezer-safe container. Thaw in the fridge overnight before reheating. Reheating: When ready to enjoy, reheat in the oven at 350°F (175°C) until warmed through, about 15-20 minutes, to maintain texture and flavor. Airtight Guidance: Always cover the pasta well to prevent freezer burn and retain its delicious creamy goodness. French Onion Soup Pasta Variations Feel free to add your own twist to this creamy delight and make it truly yours! Gluten-Free: Substitute cavatappi with your favorite gluten-free pasta, ensuring everyone can enjoy this comforting dish. Dairy-Free: Use coconut milk or almond milk in place of heavy cream to create a luscious, dairy-free béchamel sauce. Vegetarian Broth: Swap beef broth for vegetable broth for a more plant-based version while still capturing rich flavors. Cheese Variety: Experiment with cheeses like Gruyère or Fontina for added depth and different taste profiles that can switch up the whole dish.

Expert Tips for French Onion Soup Pasta Patience is Key: Caramelizing onions properly takes time; cook them slowly to bring out their natural sweetness and avoid burning. Choose Your Pasta: While cavatappi is ideal, you can swap it with any short pasta. Just ensure it’s cooked slightly under al dente to retain its texture. Béchamel Perfection: Stir continuously when adding cream to prevent lumps in the béchamel. Slowly whisking ensures a creamy, smooth sauce. Crusty Topping: For crispy breadcrumbs, spread them evenly on top and use an oven-safe skillet to transition easily from stovetop to oven. Season Wisely: Taste and adjust seasoning throughout the cooking process, especially when incorporating the beef broth and finishing with salt and pepper.
