Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize Onions
Begin by thinly slicing three large yellow onions. Heat 2 tablespoons of olive oil in a large skillet over medium heat, then add the onions. Cook them gently for 30-40 minutes, stirring occasionally, until they are golden brown and caramelized. If the onions begin to stick, add a splash of beef broth to maintain moisture and encourage sweetness in your French Onion Soup Pasta base.
Step 2: Prepare Béchamel Sauce
In the same skillet, lower the heat slightly and add 2 tablespoons of butter. Once melted, whisk in 2 tablespoons of flour, cooking for about 1 minute to form a roux. Gradually pour in 1 cup of heavy cream while whisking continuously, allowing it to thicken for about 5 minutes. Stir in ⅔ of your caramelized onions, season with salt, pepper, oregano, and a dash of garlic powder for a flavorful béchamel sauce.
Step 3: Cook Pasta
Bring a large pot of salted water to a boil and add 8 oz of cavatappi macaroni. Cook the pasta until just shy of al dente, about 6-7 minutes, as it will continue to cook in the oven. Drain the pasta and gently stir it into the warm béchamel sauce, ensuring every piece is well-coated with that rich, creamy goodness.
Step 4: Combine and Transfer
Carefully mix the remaining caramelized onions into the pasta and béchamel mixture, ensuring an even distribution. Transfer everything into an oven-safe baking dish, spreading it out evenly. This step is vital for the perfect consistency of your French Onion Soup Pasta, allowing it to bake uniformly.
Step 5: Top and Bake
Preheat your oven to 350°F (175°C). Prepare breadcrumbs by toasting pieces of baguette in olive oil until golden and crispy. Layer these breadcrumbs evenly over the pasta mixture along with any remaining caramelized onions. Bake in the preheated oven for 10-15 minutes or until the top is golden brown and irresistible.
Step 6: Serve
Once baked to perfection, remove your French Onion Soup Pasta from the oven and let it cool slightly. Serve it hot, garnished with fresh parsley, allowing everyone to dig in. The combination of creamy pasta and crispy topping will surely delight your guests, creating a perfect comfort food experience!
