Description

Creamy, cheesy brussels sprouts gratin delivers comfort on a plate with its rich, golden-brown top. Crispy edges and velvety interior promise a delightful side dish you’ll savor to the last delectable bite.


Ingredients

Scale

Main Ingredients:

  • 2 pounds Brussels sprouts (small to medium), outer leaves removed, stems trimmed, halved
  • 6 strips bacon, diced
  • 2 cups grated sharp white Cheddar cheese (or Gruyere, Fontina, or Brie)
  • 1/4 cup freshly grated Parmesan cheese

Cream and Seasoning:

  • 2 cups heavy cream
  • 1 tablespoon all-purpose flour
  • Salt, to taste
  • Freshly ground black pepper, to taste
  • 1 pinch of cayenne pepper (optional)

Topping and Preparation:

  • 2 slices butter-flavored bread (such as brioche), coarsely ground
  • 2 tablespoons salted butter, softened (or unsalted butter with a pinch of salt)
  • Butter, oil, or cooking spray (for the baking dish)

Instructions

  1. Prepare a gratin dish by lightly coating with butter or cooking spray, then set the oven temperature to 400°F for optimal heating.
  2. Create a boiling water bath with salt, quickly submerge Brussels sprouts for 3-4 minutes until they transform into a vibrant green color and become slightly tender.
  3. Immediately transfer sprouts to an ice water bath to halt cooking, then carefully dry with a clean kitchen towel to remove excess moisture.
  4. Render bacon in a deep skillet over medium heat until crispy and golden, extracting maximum flavor and creating delicious drippings.
  5. Transform bacon drippings into a luxurious sauce by whisking flour, creating a roux that will thicken and provide depth to the dish.
  6. Gradually introduce heavy cream to the roux, stirring continuously until the mixture reaches a smooth, slightly thickened consistency.
  7. Incorporate shredded cheese into the cream sauce, melting completely and creating a rich, velvety texture with gentle whisking.
  8. Season the cheese sauce with salt, black pepper, and a hint of cayenne for a subtle kick of heat.
  9. Gently fold crispy bacon pieces and blanched Brussels sprouts into the cheese sauce, ensuring every morsel is evenly coated.
  10. Transfer the creamy mixture to the prepared gratin dish, spreading it evenly to create a uniform layer.
  11. Craft a crispy topping by combining breadcrumbs, melted butter, and freshly grated Parmesan cheese using your fingertips.
  12. Sprinkle the breadcrumb mixture generously over the Brussels sprouts, creating a golden, crunchy surface.
  13. Bake uncovered in the preheated oven for 20-25 minutes, watching for a beautiful golden-brown color and bubbling edges.
  14. If the breadcrumb topping browns too quickly, loosely tent with aluminum foil to prevent burning while ensuring complete cooking.
  15. Serve immediately while the gratin is hot and the topping remains delightfully crisp.

Notes

  • Blanching Brussels sprouts helps maintain their vibrant green color and prevents overcooking, ensuring a crisp-tender texture that’s perfectly balanced.
  • Reserve some bacon drippings for extra flavor, but drain excess fat to keep the dish from becoming too greasy and heavy.
  • Experiment with different cheese combinations like Gruyère and sharp cheddar to add depth and complexity to the sauce.
  • Toast breadcrumbs in a dry skillet before adding to the topping for an extra crunch and nutty flavor that elevates the entire dish.
