Preheat your oven to 425°F. Place the Brussels sprouts on the baking sheet and drizzle with oil. Season with salt and pepper and toss to coat.
Roast the Brussels sprouts for 18-20 minutes. The pieces should be slightly crisp and fork-tender when done.
Notes
If you prefer your Brussels sprouts even more crispy, just keep cooking them to the doneness you like best. Watch closely though, as they’ll go from perfect to burnt in less than a minute once they’re done.
