Ingredients
 

Main Ingredients

  • 1.5 pounds Brussels sprouts trimmed and halved
  • 1 cup heavy cream
  • 1.5 cups shredded Gruyère cheese divided
  • 2 tablespoons unsalted butter
  • 1 clove garlic minced
  • 0.25 teaspoon sea salt
  • 0.25 teaspoon black pepper
  • 0.25 cup breadcrumbs optional, for topping

Instructions

Preparation Steps

  • Preheat your oven to 375°F (190°C). Grease a baking dish with butter.
  • In a saucepan, melt the butter over medium heat. Add garlic and sauté for 1 minute.
  • Add heavy cream, salt, and pepper to the saucepan and bring to a simmer. Remove from heat and stir in 1 cup of the Gruyère cheese.
  • Place the Brussels sprouts in the baking dish and pour the cream mixture over the top. Stir to coat evenly.
  • Sprinkle with remaining Gruyère cheese and breadcrumbs, if using.
  • Bake for 30 minutes, until bubbly and golden brown. Let cool for a few minutes before serving.

Notes

This gratin can be made ahead of time and baked just before serving. For a lighter version, substitute half-and-half for the heavy cream.
