• Discover the key elements that make this dish unforgettable!
For the Pasta
- Cavatappi Macaroni – This spiral pasta holds sauce beautifully; substitute with penne or rotini if desired.
For the Breadcrumb Topping

- Onions (5, thinly sliced) – Sweet caramelized flavor is essential; shallots can give a milder taste.

- Heavy Cream (3 cups) – Adds richness to the sauce; substitute with coconut milk for a lighter, vegan-friendly option.
- Parmesan Cheese (1 cup, grated) – Provides creaminess; nutritional yeast or plant-based cheese works for a dairy-free dish.

Now that we have our French Onion Soup Pasta ingredients lined up, let’s get cooking!
Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize the Onions
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the thinly sliced onions and a pinch of salt, sautéing for 30–40 minutes. Stir occasionally, allowing the onions to soften and turn golden brown. This slow caramelization is key for achieving that rich, sweet flavor reminiscent of a classic French onion soup.
Step 2: Speed Up Caramelization (Optional)
If you wish to speed up the process, sprinkle in 1 teaspoon of sugar to enhance the caramelization. Should the onions begin to stick to the skillet, pour in ½ cup of beef broth and scrape the bottom to deglaze. Continue simmering for an additional 10 minutes until the onions are deeply golden and deliciously fragrant.
Step 3: Make the Béchamel Sauce
In the same skillet, lower the heat and melt 2 tablespoons of butter. Whisk in 1 tablespoon of flour, cooking for 1–2 minutes until the mixture is bubbling. Gradually add 3 cups of heavy cream while whisking constantly until thickened, about 5 minutes. Stir in two-thirds of the caramelized onions, seasoning with salt, pepper, and freshly chopped parsley for extra flavor.
Step 4: Cook the Pasta
Bring a large pot of salted water to a vigorous boil. Add 12 ounces of cavatappi macaroni and cook until just shy of al dente, about 7-8 minutes. Drain the pasta, reserving a cup of the cooking water, and set it aside. The pasta will finish cooking in the oven when combined with the béchamel sauce.
Step 5: Combine Pasta and Sauce
In a large mixing bowl, combine the cooked pasta with the béchamel sauce, ensuring the pasta is evenly coated. If the mixture appears too thick, stir in a bit of the reserved pasta water until you reach a creamy consistency. This step is crucial for achieving that luscious texture found in French Onion Soup Pasta.
Step 6: Assemble the Dish
Transfer the pasta mixture to a greased baking dish, spreading it out evenly. Layer the remaining caramelized onions over the top, allowing the sweet flavor to shine through. Next, sprinkle homemade breadcrumbs generously on top, creating a beautiful crunchy layer that mirrors traditional French onion soup.
Step 7: Bake to Perfection
Preheat your oven to 350°F (175°C) and bake the assembled dish uncovered for 10–15 minutes. You’re looking for a golden, crispy topping that contrasts nicely with the creamy pasta underneath. Keep an eye on it to ensure it doesn’t burn, as that crispy texture is just what you want!
Step 8: Serve Warm
Once baked, remove the French Onion Soup Pasta from the oven and let it cool for a few minutes. Serve warm, garnished with a sprinkle of fresh parsley if desired. This hearty dish is perfect as a cozy dinner or an impressive gathering meal, delivering the comforting flavors of French onion soup in a satisfying pasta form.

Helpful Tricks for French Onion Soup Pasta

Breadcrumb Options: For extra crunch, mix in some grated Parmesan cheese with the breadcrumbs before baking. This enhances both flavor and texture.
-
Make-Ahead Tip: Prepare the caramelized onions and béchamel sauce in advance. Store them separately, then mix with fresh pasta before baking for an effortless dinner!
