How to Make French Onion Soup Pasta : Step-by-Step

1. Toast & Blend the Breadcrumbs

Start by giving your baguette new life. Slice it thin, toss it with olive oil and oregano, and toast at 300°F for about 7–10 minutes until just golden. Once cooled, blitz those slices in a food processor until they turn into fine, golden breadcrumbs.

2. Caramelize the Onions

This part takes patience, but it’s worth every second. Slice your onions into long strips and sauté in olive oil over medium heat for 30–40 minutes. Stir occasionally and let them get that deep, golden-brown color. Optional: Add a teaspoon of sugar to speed things up if you’re in a pinch.

3. Make the Creamy Béchamel Sauce

In the same skillet, melt some butter and whisk in the flour. Cook for about a minute, then gradually stir in the heavy cream. Let it thicken slightly before folding in ⅔ of your caramelized onions. Add parsley, salt, pepper, and a generous handful of Parmesan.

4. Cook the Pasta

While the sauce simmers, boil your pasta until just shy of al dente. Drain and mix it into your oniony, creamy béchamel.

5. Bake & Serve

Pour the sauced pasta into a baking dish. Top with the rest of the caramelized onions and those crunchy breadcrumbs. Bake at 350°F for 10–15 minutes until the top is golden and irresistible.

Serve hot, scoop generously, and enjoy that first bite that tastes like pure cozy.

Tips for the Best French Onion Soup Pasta

Don’t rush the onions—they’re the heart of this dish.
Use a mix of cheeses if you’re feeling bold (Gruyère is divine here).
Got leftovers? They reheat like a dream the next day.
Try air-frying the breadcrumb topping for extra crunch.

A Personal Note

The first time I made this recipe, I was juggling a laundry pile taller than my toddler and had zero energy left for a complicated dinner. But slow-cooking those onions felt oddly therapeutic, and by the time we sat down, it was like the stress melted right into that cheesy crust. It’s now one of our go-to’s when life feels too full—and trust me, that’s often.

FAQs About French Onion Soup Pasta

Cavatappi holds the sauce beautifully, but penne, fusilli, or even rigatoni work just as well.
