French Onion Soup Pasta Ingredients • All the essentials to create this comforting dish await you! For the Pasta Cavatappi Macaroni – This shape is perfect for catching the creamy béchamel sauce and the caramelized onions, enhancing every bite. For the Sauce Onions – These are the star of the dish; caramelizing them adds a sweet depth that mimics traditional French onion soup. Beef Broth – It boosts the umami flavor; you can easily substitute with vegetable broth for a vegetarian option. Heavy Cream – This contributes to a rich, creamy texture in the béchamel; swap for coconut milk to make it dairy-free. Flour – This thickens the béchamel sauce; you can use cornstarch for a gluten-free alternative. For the Topping Breadcrumbs – They provide a crunchy topping; using panko breadcrumbs can save you time while still offering great texture. Parmesan Cheese – Adds a salty, nutty flavor to the dish; consider nutritional yeast for a vegan-friendly substitution. Fresh Parsley – This herb garnishes the dish with a hint of freshness; feel free to adjust or use different herbs to suit your taste. For Seasoning Salt & Pepper – Essential for balancing flavors; ensure to season thoughtfully throughout the cooking process. Garlic Powder – Adds an extra layer of flavor; fresh garlic can be used for a bolder taste. Smoked Paprika – Gives a subtle smokiness to the dish, enhancing the overall flavor profile. Nutmeg – Just a pinch can elevate the creaminess of the béchamel, perfectly matching the French onion theme. Sugar – A small amount can help speed up caramelization, yielding sweet, golden onions more quickly. Start gathering these ingredients, and let’s transform your kitchen into a cozy haven with this delightful French Onion Soup Pasta! Step‑by‑Step Instructions for French Onion Soup Pasta Step 1: Caramelize the Onions Begin by thinly slicing three large onions. Heat a tablespoon of olive oil in a large skillet over medium heat. Add the sliced onions, stirring occasionally for 30–40 minutes until they turn a beautiful golden brown and caramelize. If they begin to stick, sprinkle in a pinch of sugar and add a splash of beef broth to help them along. Step 2: Prepare the Béchamel Sauce In the same skillet, lower the heat slightly and add 2 tablespoons of butter to melt. Once melted, whisk in 2 tablespoons of flour to create a roux, cooking for about 2 minutes until golden. Gradually pour in 1 cup of heavy cream, stirring continuously until the sauce thickens and bubbles, about 5–7 minutes. Mix in two-thirds of the caramelized onions, seasoning with salt, pepper, and a dash of nutmeg. Step 3: Cook the Pasta While your béchamel sauce thickens, bring a large pot of salted water to a boil. Add 8 ounces of cavatappi macaroni and cook until just under al dente, about 7-8 minutes, since the pasta will continue cooking in the oven. Drain the pasta and reserve a cup of the pasta water for later use if needed. Step 4: Combine Pasta and Sauce Transfer the drained cavatappi to the skillet with the béchamel sauce. Gently fold in the remaining caramelized onions, ensuring every piece of pasta is coated in that creamy goodness. If your mixture seems thick, add a little reserved pasta water to achieve your desired consistency. Step 5: Top and Bake Preheat your oven to 350°F (175°C). Pour the pasta mixture into a greased baking dish and spread it out evenly. Generously sprinkle the top with breadcrumbs, ensuring a nice layer covers the surface. Bake uncovered for 10-15 minutes, or until the top is golden brown and crispy, creating a beautiful contrast with the creamy pasta underneath. Step 6: Serve and Enjoy Once out of the oven, let your French Onion Soup Pasta sit for about 5 minutes before serving. Garnish with freshly chopped parsley for a pop of color and added freshness. Portion out the pasta and enjoy this comforting meal while it’s warm, allowing its rich flavors to fill your kitchen with delightful aromas.

Expert Tips for French Onion Soup Pasta • Patience Pays: Slow caramelization of onions brings out their natural sweetness. Rushing can result in bitter flavors, so savor the process! • Smooth Sauce: To avoid lumps in your béchamel, whisk vigorously while gradually adding the cream. If lumps do occur, ice-cold water can work wonders! • Perfect Pasta: Cook your cavatappi just under al dente; this way, it’ll soften perfectly during baking without becoming mushy. • Freezing Tips: If you plan to freeze leftovers, let the casserole cool completely in an airtight container. This keeps it fresh for 2 months and makes reheating easy! • Cheesy Flavor Boost: For that extra oomph, mix in a bit of grated cheese into the béchamel sauce before combining with the pasta—yum! • Season to Taste: Adjust salt and pepper based on your broth’s saltiness. Taste as you go to ensure a perfectly balanced French Onion Soup Pasta! Make Ahead Options These Creamy French Onion Soup Pasta delights are perfect for busy home cooks looking to save time! You can caramelize the onions up to 3 days ahead; simply allow them to cool and store them in an airtight container in the refrigerator. When planning to serve, prepare the béchamel sauce and mix in the cooked pasta (which can also be prepared up to 24 hours in advance and stored in the fridge). To maintain quality, add a splash of cream or broth while reheating the pasta prior to baking. Finally, combine everything, top with breadcrumbs, and bake directly from the fridge for that comforting, restaurant-quality finish with minimal fuss. Enjoy your time-saving delight! French Onion Soup Pasta Recipe FAQs What type of onions should I use for the best flavor? Absolutely! For the sweetest and most flavorful onion caramelization, I recommend using yellow onions. They break down beautifully and develop that rich sweetness we all love in French onion soup. If you want a slightly sharper flavor, you can mix in some red onions or sweet onions like Vidalias. How should I store any leftover French onion soup pasta? To keep your delicious creation fresh, store the leftovers in an airtight container in the refrigerator for up to 3-4 days. Make sure it’s completely cooled before sealing. When reheating, a splash of cream or water can help restore its creamy texture! Can I freeze French onion soup pasta? Very! To freeze, let the pasta cool completely, then transfer it into freezer-safe containers or bags. This dish can be stored for up to 2 months. When you’re ready to enjoy it again, simply thaw it overnight in the fridge and reheat in the oven, adding a touch of cream or water to revitalize its creamy goodness. What if my béchamel sauce turns out lumpy? Don’t worry, it happens! If your sauce has small lumps, try whisking in some ice-cold water, a tablespoon at a time, until smooth. If it’s overly thick, you can add more cream or broth to achieve the desired consistency. Is there a way to make French onion soup pasta dairy-free? Absolutely! You can substitute heavy cream with coconut milk for creaminess, and use nutritional yeast instead of Parmesan cheese for that cheesy, rich flavor. Plus, make sure to use vegetable broth instead of beef broth to keep it vegetarian-friendly. What can I serve with French onion soup pasta?
