How to Make Brussels Sprouts Au Gratin
Step 1: Prepare the Brussels Sprouts
First, trim and halve the Brussels sprouts, then blanch them in boiling salted water for 3-4 minutes until just tender but still bright green. Drain and set aside to dry.
Step 2: Make the Cheese Sauce
Melt butter in a saucepan over medium heat, then whisk in flour to form a smooth roux. Slowly add milk or cream, whisking constantly until the sauce thickens. Stir in grated Gruyère, Parmesan, minced garlic, salt, and pepper until the cheese melts fully and the sauce is creamy and smooth.
Step 3: Combine and Transfer
Mix the cooked Brussels sprouts with the cheese sauce, ensuring each piece is nicely coated. Pour everything into a buttered baking dish evenly.
Step 4: Add Topping and Bake
Sprinkle additional Parmesan cheese and breadcrumbs over the top if using. Bake in a preheated oven at 375°F (190°C) for 20-25 minutes until bubbling and golden brown on top.
Step 5: Serve Warm
Let the dish rest for a few minutes after baking before serving to allow the sauce to set slightly and flavors to meld perfectly.
Pro Tips for Making Brussels Sprouts Au Gratin
- Use Fresh Sprouts: Fresh, firm Brussels sprouts give the best texture and flavor compared to frozen.
- Don’t Overcook Sprouts: Blanch just long enough to soften slightly; overcooking makes them mushy.
- Cheese Choice Matters: Gruyère offers the best melt and flavor, but mixing cheeses adds complexity.
- Prepare Ahead: Assemble the dish in advance and refrigerate until baking time to save effort on busy days.
- Watch the Baking Time: Remove once the top is golden to avoid drying out the sauce.
