French Onion Soup Pasta Ingredients
For the Breadcrumbs
• ½ Baguette – For homemade breadcrumbs; use pre-made as a quick alternative.
• 1 tablespoon Olive Oil – For sautéing; butter works well too if you want a richer flavor.
For the Pasta
• 300 g Cavatappi Macaroni – The pasta base; any sturdy pasta shape can hold the cream sauce well.
• 2 teaspoons Salt – Enhances flavor; adjust as needed for your taste.
For the Onion Mixture
• 5 Onions (thinly sliced) – Essential for caramelization, giving a sweet base; yellow onions are best.
• ½ cup Beef Broth – Deepens the onion flavor; switch to vegetable broth for a vegetarian option.
• 1 teaspoon Sugar – Optional, helps caramelize onions; enhances sweetness for a richer taste.
For the Béchamel Sauce
• 3 cups Heavy Cream – Forms the creamy base; consider coconut milk for a dairy-free version.
• 1 cup Parmesan Cheese (grated) – Adds creaminess; use nutritional yeast for a vegan alternative.
• 1 tablespoon Flour + 3 tablespoons Water – Thickens the béchamel; cornstarch mixed with water can serve as a gluten-free substitute.
• 1 teaspoon Salt – Seasoning for the sauce; feel free to adjust to your liking.
• 1 tablespoon Garlic Powder – Adds depth of flavor; fresh minced garlic is a great alternative.
• 1 tablespoon Smoked Paprika Powder – Introduces a subtle smokiness; regular paprika can be used instead.
• ½ teaspoon Nutmeg – Enhances the béchamel sauce’s flavor; optional but brings warmth.
For Garnish
• Fresh Parsley (chopped) – Adds a pop of color; switch to chives for a different herb touch.
Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize Onions
Start by thinly slicing the five onions and heating 1 tablespoon of olive oil in a large skillet over medium heat. Sauté the onions for 30–40 minutes, stirring occasionally, until they turn a beautifully deep golden brown. If you find them sticking, add ½ cup of beef broth to deglaze the pan and continue simmering for an additional 10 minutes for extra flavor in your French Onion Soup Pasta.
Step 2: Prepare Béchamel Sauce
In the same skillet with the caramelized onions, melt 2 tablespoons of butter over low heat. Whisk in 1 tablespoon of flour until smooth, then gradually add 3 cups of heavy cream while whisking continuously to avoid lumps. Once combined, stir in ⅔ of the caramelized onions and season with 2 teaspoons of salt, pepper, freshly chopped parsley, and 1 cup of grated Parmesan, creating a rich béchamel sauce.
Step 3: Cook Pasta
Bring a large pot of salted water to a boil. Add 300 grams of cavatappi macaroni and cook until just under al dente, about 7–8 minutes (it will continue cooking in the oven). Drain the pasta, reserving a bit of pasta water in case you need to thin the béchamel. This step ensures your French Onion Soup Pasta has the perfect texture and sauce adhesion.
Step 4: Combine & Bake
Preheat your oven to 350°F (175°C) while you combine the cooked pasta with the béchamel sauce in the skillet or a baking dish. Mix thoroughly until the pasta is well-coated. Layer the remaining caramelized onions on top and sprinkle with homemade breadcrumbs. Bake in the preheated oven for 10–15 minutes, or until the top is golden and crispy, adding an inviting crunch to your dish.
Step 5: Serve
Remove the French Onion Soup Pasta from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley for a vibrant touch. Serve this comforting dish warm, and relish the creamy goodness as you enjoy the blend of flavors. Perfect for cozy evenings or impressing your guests!
