Trim the ends of the Brussels sprouts and remove any loose or damaged outer leaves. Optionally, cut them in half for faster cooking.
Preheat your Blackstone griddle to medium-high heat. Ensure even heating across the cooking surface.
Drizzle a bit of olive oil or your preferred cooking oil onto the griddle's surface and spread it evenly.
Place the prepared Brussels sprouts on the hot griddle, ensuring they are in a single layer without overcrowding.
Season the Brussels sprouts with salt and pepper or your preferred seasonings. Get creative with flavors like garlic powder, paprika, or Parmesan cheese.
Allow the Brussels sprouts to cook without moving them too frequently. Flip them over using a spatula or tongs when they develop a nice char on one side.
Cook the Brussels sprouts until they are tender on the inside and have a crispy, caramelized exterior. This typically takes about 10-15 minutes, depending on size and heat.
Transfer the cooked Brussels sprouts to a serving platter, and they're ready to enjoy.
Add extra flavor by drizzling balsamic glaze, sprinkling grated Parmesan cheese, or tossing with minced garlic after cooking.
