Brussels Sprouts Gratin – Golden, Cheesy, and Surprisingly Addictive

Brussels Sprouts Gratin

Introduction

Golden, creamy, and loaded with flavor, this Brussels Sprouts Gratin takes a humble vegetable and turns it into a cheesy, crowd-pleasing side dish that might just steal the show. Roasted and then blanketed in cream, bacon, cheddar, and breadcrumbs, it’s everything you want in a cozy casserole—crunchy on top, melty in the middle, and just enough heat to keep it interesting.

Whether you’re serving it for Thanksgiving or a simple weeknight dinner, this gratin delivers comfort in every bite.


Why I Love This Recipe

Let’s be honest—Brussels sprouts have a reputation. But once they’re chopped, roasted, and bathed in cheese and cream, even skeptics come back for seconds. I especially love the salty crunch from the turkey or beef bacon and the way the cream bubbles up under a golden breadcrumb crust.

It hits the same comfort chord as our Dorito Casserole or Chicken Enchiladas—rich, satisfying, and always welcome at the table.


Recipe Details

  • Yield: 6 servings
  • Prep Time: 15 minutes
  • Cook Time: 15 minutes
  • Total Time: 30 minutes

Ingredients

  • 2 tablespoons unsalted butter, cut into pieces (plus more for greasing)
  • 8 oz turkey or beef bacon, cooked and chopped
  • 1 pound Brussels sprouts, trimmed
  • Pinch of red pepper flakes (optional)
  • Salt and freshly ground black pepper, to taste
  • ½ cup heavy cream
  • ½ cup grated white cheddar cheese
  • ½ cup breadcrumbs

Optional Swaps and Tips

  • Cheese: Try Gruyère, Parmesan, or mozzarella for different flavor profiles.
  • Breadcrumbs: Panko gives an extra-crispy top; seasoned ones add a flavor boost.
  • Add-ins: Stir in a few sautéed mushrooms or caramelized onions for more depth.
  • No bacon? Use smoked paprika or a dash of liquid smoke for a similar vibe.

Instructions

1. Prep the Oven and Dish

  • Preheat oven to 400°F (200°C).
  • Lightly grease a 2-quart baking dish with butter.

2. Cook the Brussels Sprouts

  • Bring a pot of salted water to a boil.
  • Cook Brussels sprouts for 8–10 minutes until tender.
  • Drain, cool slightly, and coarsely chop.

3. Cook the Bacon

  • In a skillet, cook turkey or beef bacon until crisp.
  • Drain on paper towels and chop into small pieces.

4. Assemble the Gratin

  • Add chopped Brussels sprouts and half the bacon to the baking dish.
  • Season with salt, pepper, and red pepper flakes (if using).
  • Pour in heavy cream and sprinkle with cheese.
  • Top with the remaining bacon and breadcrumbs.
  • Dot the top with butter pieces.

5. Bake

  • Bake for 15 minutes, or until bubbling and golden on top.
  • Let cool slightly before serving.

Tips for Success

  • Don’t overcook sprouts in the water—they’ll continue softening in the oven.
  • Use a shallow baking dish to get maximum golden crust.
  • Let it rest a few minutes before serving—it sets up and cuts cleanly.
