Notes
Serve right away; the cheese crust is crispiest fresh from the oven.

Frequently Asked Questions
How do you keep Brussels sprouts from getting soggy?
Roast at high heat on a preheated pan, dry the sprouts well, and avoid crowding the pan.
Can I use frozen Brussels sprouts for roasting?
Yes, but they will not get as crispy. Roast from frozen at 425°F and increase the cooking time by 5 to 10 minutes.
Why are my Brussels sprouts bitter?
Overcooking or boiling can amplify bitterness. Roasting caramelizes natural sugars and balances the flavor.
Can I make crispy Brussels sprouts ahead?
Trim and halve them a day ahead, then roast right before serving for the best crispness.
