• Here’s everything you need for this creamy, comforting dish.
For the Crispy Topping
- Breadcrumbs – Provide a crispy texture; use pre-made panko for convenience if needed.
- Baguette – Acts as the base for homemade breadcrumbs; check for gluten-free options if necessary.
- Olive Oil – Essential for sautéing onions and toasting breadcrumbs; any cooking oil works as a substitute.
For the Pasta Dish
- Cavatappi Macaroni – This pasta holds sauce well; substitute with gluten-free pasta if desired.
- Onions – The key flavor component; caramelize for sweetness—yellow or sweet onions work best.
- Beef Broth – Enhances onion flavor during caramelization; swap with vegetable broth for a vegetarian version.
- Heavy Cream – Provides richness to the béchamel sauce; coconut cream can be used for a dairy-free alternative.

- Flour – Used for thickening the béchamel; gluten-free flour works well too.
- Salt – Enhances flavor; adjust according to taste.

Step‑by‑Step Instructions for Creamy French Onion Soup Pasta
Step 1: Caramelize the Onions
Slice the onions thinly and heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onions and stir to coat; cook for 30-40 minutes, stirring occasionally, until they are golden brown and sweet smelling. If desired, add a teaspoon of sugar midway through to enhance caramelization.
Step 2: Prepare the Béchamel Sauce
Once the onions are caramelized, reduce the heat to medium-low and add 3 tablespoons of butter to the same skillet. Let it melt before whisking in 3 tablespoons of flour until it forms a paste. Gradually pour in 2 cups of heavy cream, whisking continuously for about 5-7 minutes until the sauce thickens and is smooth; if lumps form, add a splash of ice-cold water and whisk vigorously.
Step 3: Combine Onions and Sauce
Stir ⅔ of the caramelized onions into the béchamel sauce, mixing well. Season with salt, pepper, a pinch of garlic powder, and a sprinkle of oregano for extra flavor. Allow this mixture to gently simmer on low heat for about 5 minutes, letting the flavors meld beautifully in your creamy French onion soup pasta.
Step 4: Cook Pasta
In a large pot, bring salted water to a boil and add 12 ounces of cavatappi macaroni. Cook the pasta until just below al dente, about 1-2 minutes less than package instructions, then drain the pasta, reserving a cup of the pasta water. This step is crucial to ensure the pasta retains some firmness and absorbs the béchamel later.
Step 5: Mix Pasta and Sauce
Return the drained pasta to the pot over low heat. Immediately pour the béchamel sauce over the pasta, stirring to combine thoroughly. If the sauce appears overly thick, gradually add reserved pasta water, one tablespoon at a time, until the desired creamy consistency is achieved, ensuring every piece of pasta is well coated.
Step 6: Assemble for Baking
Transfer the pasta mixture into a greased baking dish, spreading it evenly. Top with the remaining caramelized onions and a generous layer of homemade breadcrumbs, which can be made from a baguette and toasted in olive oil for added crispiness. The assembly builds layers of flavor that elevate the creamy French onion soup pasta.
Step 7: Bake
Preheat your oven to 350°F (175°C). Bake the assembled pasta dish uncovered for 10-15 minutes until the top is golden brown and crispy. Keep an eye on it as it bakes to achieve that perfect crunchy topping while the creamy interior remains warm and inviting, a fitting conclusion to your culinary endeavor.
