Preheat oven to 450°F (232°C). Line a large rimmed baking sheet with parchment paper. Place it on the lower rack while the oven heats to ensure it gets very hot.
STEP 1: PREHEAT THE OVEN & PAN
STEP 2: SEASON THE SPROUTS
In a large bowl, toss the frozen Brussels sprouts with olive oil, salt, and pepper until coated.
STEP 3: SPREAD ON HOT PAN
Using oven mitts, carefully remove the hot baking sheet. Pour sprouts into the center and quickly spread into an even layer with a spatula.
STEP 4: ROAST UNTIL CRISPY
Roast for 15 minutes, then remove pan and toss sprouts. Return to oven and roast another 10–15 minutes, until deeply browned and fork-tender.
STEP 5: FINISH & SERVE
Top with a squeeze of lemon juice or sprinkle with Parmesan before serving hot.
PRO TIPS
- Roast the Brussel spouts while frozen for crispier edges
