Serves 4 hearty portions
Difficulty Level
Easy – perfect for a cozy weeknight meal or festive gatherings
Ingredients
- 1 ½ pounds Brussels sprouts, trimmed and halved
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour, sifted
- 2 cups whole milk, warmed
- 1 cup sharp white cheddar cheese, shredded
- ½ cup Gruyère cheese, shredded
- 1 teaspoon Dijon mustard
- ½ teaspoon freshly grated nutmeg
- Salt and freshly ground black pepper, to taste
- ½ cup panko breadcrumbs
- 2 tablespoons Parmesan cheese, finely grated
- 1 tablespoon olive oil
Instructions
- Select and Prepare: Begin by choosing bright green Brussels sprouts with tightly closed leaves. Trim the stems and cut each sprout in half lengthwise. Rinse thoroughly under cold water, removing any yellow or damaged outer leaves. This ensures freshness and maximum flavor in your gratin.
- Blanch the Brussels Sprouts: Bring a large pot of salted water to a boil. Add the halved Brussels sprouts and blanch for 4 minutes until just tender but still vibrant. Drain immediately and plunge into an ice bath to stop cooking, preserving their bright color and texture.
- Make the Creamy Cheese Sauce: In a medium saucepan, melt the butter over medium heat. Gradually whisk in the sifted flour, cooking for 2 minutes to form a roux without browning it. Slowly add the warm milk, whisking constantly until the mixture thickens and coats the back of a spoon, about 6-8 minutes. Remove from heat and stir in the Dijon mustard, nutmeg, and the shredded cheddar and Gruyère cheeses. Season with salt and pepper. This silky sauce is the heart of your gratin, elevating the Brussels sprouts to rich indulgence.
- Combine and Layer: Preheat your oven to 375°F (190°C). Gently fold the blanched Brussels sprouts into the cheese sauce, ensuring even coating. Transfer the mixture to a buttered baking dish, spreading it out evenly to create a uniform layer ready for topping.
- Prepare the Crispy Topping: In a small bowl, stir together panko breadcrumbs, Parmesan cheese, and olive oil until the crumbs are lightly coated. This topping will bake into a golden, irresistibly crispy crust that contrasts beautifully with the creamy interior.
- Bake to Perfection: Sprinkle the breadcrumb mixture evenly over the Brussels sprouts. Bake in the preheated oven for 25-30 minutes, or until the topping is golden brown and bubbling around the edges. For extra crispness, broil for an additional 2-3 minutes, watching carefully to prevent burning.
- Rest and Serve: Allow the gratin to rest for 5 minutes before serving. This short pause lets the sauce settle slightly, making each spoonful perfectly luscious yet structured.
Chef’s Notes: Tips for Success
- Brussels sprouts can vary in size: For larger sprouts, quarter them to ensure even cooking and a tender bite.
- Cheese Variations: Swap Gruyère for Fontina or Emmental for a lighter, nuttier flavor profile.
- Make-ahead option: Prepare the gratin up to step 5, cover with foil, and refrigerate overnight. Bake just before serving, adding 5 minutes to the baking time.
- Breadcrumb alternatives: For a more rustic crunch, crushed toasted walnuts or pecans can replace panko.
- To avoid a watery gratin: Ensure sprouts are as dry as possible after blanching by patting gently with paper towels.
Serving Suggestions
Present this warming Easy Brussels Sprouts Gratin alongside a carved roast chicken or a rich mushroom stroganoff for a savory, comforting feast. Garnish generously with fresh thyme sprigs or finely chopped chives to add a fresh herbal note and vibrant color.
