Preheat your oven to 400°F and line two large baking sheets with parchment paper. Trimming brussels sprouts takes about ten minutes, so slice each one in half lengthwise and discard any yellowed outer leaves. Pat them completely dry with paper towels—this step creates the crispy exterior everyone loves.

In a large bowl, combine olive oil with salt, black pepper, garlic powder, and cayenne pepper. Toss the brussels sprouts halves in this mixture until every piece glistens with seasoned oil. Arrange them cut-side down on your prepared baking sheets in a single layer without crowding.

Roast for 25-28 minutes at 400°F, checking halfway through to ensure even browning. The cut sides should turn deep golden brown and crispy while the rounded tops stay tender. This timing produces brussels sprouts crowd recipes with the ideal texture contrast.

While the vegetables roast, whisk together balsamic vinegar and maple syrup in a small bowl until combined smoothly. Once the sprouts finish roasting and achieve that beautiful caramelization, remove them from the oven and immediately drizzle with the glaze.

Sprinkle fresh thyme leaves and grated parmesan cheese over the warm brussels sprouts. Toss gently to coat everything in the glaze, and taste for seasoning adjustments. Transfer to your serving platter immediately while still warm—this maintains the crispiness and helps the cheese melt slightly into the grooves.
