The Secret to Perfectly Roasted Brussels Sprouts

Roasting Brussels sprouts is straightforward, but a few simple techniques make all the difference:

1. Halve Them Evenly

Flat sides get crisp. Cut any large sprouts into quarters.

2. Dry Completely Before Roasting

Moisture equals steaming, not crisping. Pat dry after washing.

3. Use High Heat

425°F (220°C) gives you browning and caramelization without burning.

4. Don’t Overcrowd

Space between the sprouts ensures they roast instead of steam.

5. Roast Flat-Side Down

This ensures maximum crispiness and flavor.

6. Add Parmesan at the Right Time

Roasting Parmesan directly on the sprouts helps it melt and crisp into a delicious crust.
