Cheesy Brussels Sprouts Gratin with Crispy Beef Bacon Recipe

Brussels sprouts are one of those vegetables that people either adore or avoid — until they try them in a gratin like this. This dish is where crispy, smoky beef bacon meets tender roasted Brussels sprouts, all cloaked in a creamy cheddar cheese sauce and finished with a golden breadcrumb topping. It’s decadent, comforting, and totally crave-worthy.

Let’s talk texture: you get crispy bacon bites, creamy cheesy sauce, tender sprouts, and that crunch on top — it’s a bite of bliss every time. This recipe turns Brussels sprouts from an everyday veggie into a side dish showstopper.

If you’ve only had boiled Brussels sprouts and weren’t impressed, this gratin will change everything. Roasting brings out their natural sweetness, while the rich cheddar and cream mixture gives the dish that luxurious holiday-worthy flavor.

And the beef bacon? It adds a smoky, savory kick that complements the veggies beautifully. We’re using beef or turkey bacon here to bring all that umami flavor without the need for pork.

This dish is perfect for Thanksgiving, Christmas, or anytime you want to bring a hearty, cheesy vegetable dish to the table. Even the pickiest eaters can’t resist the crispy topping and cheesy center.

Making this recipe couldn’t be easier. It’s a one-pan bake that looks elegant and tastes gourmet. Prep it in advance and just reheat before serving. It also travels well if you’re bringing it to a potluck or holiday dinner.

The creamy cheddar sauce comes together quickly, and we use white cheddar for its sharp, tangy flavor that pairs so well with Brussels sprouts. The sauce coats every leaf and flake perfectly.

Want to make it your own? Try mixing in sautéed shallots or a sprinkle of crushed red pepper flakes for a little heat. You can also use a mix of cheeses — Gruyère or Fontina are amazing in this.

This gratin doesn’t just belong on special occasions — it’s easy enough for Sunday dinner or meal prep. Pair it with roasted chicken, steak, or even a vegetarian main.

If you’re looking to sneak more veggies into your meals without sacrificing indulgence, this dish is your best friend. It’s hearty, satisfying, and downright delicious.

Leftovers are fantastic — the flavors deepen, and the cheese firms up beautifully. Just pop it in the oven to re-crisp the topping, and it’s like new again.

There’s nothing more comforting than a bubbling casserole coming out of the oven, and this one delivers every time. It’s warm, melty, crispy, and full of bold flavor.

So if you’re on the fence about Brussels sprouts, give this gratin a shot. It might just become your new favorite comfort food.
