Timing

Stage	Time
Preparation	10 minutes
Roasting	20–25 minutes
Total Time	30–35 minutes

Roasting at high heat ensures crispy edges in 25 minutes, which is 40% faster than some slow-roasted vegetable recipes.

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or a silicone mat.

High heat promotes browning and caramelization.

Step 2: Prepare the Brussels Sprouts

Trim the ends and slice each sprout in half lengthwise.

Pat dry to remove moisture, which helps achieve crispiness.

Step 3: Season the Brussels Sprouts

In a large bowl, toss Brussels sprouts with:

Olive oil
Minced garlic
Salt and black pepper

Ensure each piece is evenly coated.

Step 4: Roast the Brussels Sprouts

Arrange sprouts cut-side down on the baking sheet in a single layer.

Roast for 20–25 minutes, flipping halfway if necessary, until sprouts are golden brown and crispy on the edges.

Pro Tip: Overcrowding the pan can cause steaming instead of roasting, reducing crispiness.

Step 5: Add Parmesan

Remove the baking sheet from the oven and immediately sprinkle grated Parmesan cheese over the hot Brussels sprouts.

Toss gently to coat.

Step 6: Optional Garnishes

Enhance flavor and presentation by adding:

Lemon zest for brightness
Crushed red pepper flakes for heat
Fresh parsley for color

Serve immediately while crispy.
