Description

Think of this dish as the grown-up cousin of green bean casserole—roasted Brussels sprouts tucked into a creamy, cheesy sauce, topped with a crispy Parmesan-panko crust. It’s rich, golden, and irresistibly comforting, while still bringing a touch of freshness to the table.


Ingredients

Scale

1 ½ lbs Brussels sprouts, trimmed & halved

2 tbsp olive oil

2 tbsp butter

2 tbsp flour

1 ½ cups milk (whole or 2%)

1 cup Gruyère or white cheddar, shredded

½ cup Parmesan, grated (divided)

½ tsp nutmeg (optional, for warmth)

Salt & black pepper to taste

½ cup panko breadcrumbs


Instructions

Roast sprouts: Toss Brussels sprouts with olive oil, season with salt and pepper, and roast at 400°F (200°C) for 20 minutes until caramelized.

Make sauce: Melt butter in a saucepan, whisk in flour, and cook 1 min. Slowly whisk in milk until smooth. Stir in Gruyère, half the Parmesan, nutmeg, salt, and pepper.

Assemble: Fold roasted Brussels sprouts into the cheese sauce and transfer to a baking dish.

Top & bake: Combine panko with remaining Parmesan. Sprinkle on top and bake at 375°F (190°C) for 20 minutes until bubbly and golden.

Serve warm: Perfect alongside roasts or holiday mains.
