How to Make Brussels Sprouts Au Gratin

Step 1: Prepare Brussels Sprouts

Start by trimming the ends off fresh Brussels sprouts and removing any yellow or damaged outer leaves. Cut them in half for even cooking and better sauce absorption. Blanch them briefly in boiling water until just tender, then drain well to keep excess moisture from soggy results.

Step 2: Make the Cheese Sauce

Melt butter in a saucepan over medium heat, then whisk in flour to create a roux. Cook until slightly golden to remove the raw flour taste. Gradually add milk while whisking continuously to avoid lumps. Simmer gently until thickened, then stir in shredded Gruyere and half the Parmesan until smooth and creamy. Season with garlic powder, onion powder, salt, and pepper.

Step 3: Combine and Bake

Mix the blanched Brussels sprouts in the cheesy sauce until well coated. Transfer everything into a buttered baking dish. Sprinkle the remaining Parmesan and panko breadcrumbs on top for a crunchy, golden crust. Bake in a preheated oven at 375°F (190°C) for 20-25 minutes or until bubbly and browned on top.

Pro Tips for Making Brussels Sprouts Au Gratin

• Blanch for best texture: Par-cooking Brussels sprouts ensures tenderness without mushiness.
• Use freshly grated cheese: Avoid pre-shredded cheese to prevent clumping and improve melt quality.
• Don’t skip seasoning: Proper seasoning brings out the natural sweetness in Brussels sprouts and enhances the cheese sauce.
• Customize breadcrumbs: Toast panko with butter before topping for an extra nutty flavor.
• Rest before serving: Let the gratin cool slightly after baking to set the sauce for cleaner slices.
