Preheat your oven to 425°F. Place the broccoli on the baking sheet and drizzle with oil. Season with salt and pepper and toss to coat.
Roast the broccoli for 20 to 25 minutes. Watch the broccoli towards the end of the cooking time as smaller pieces will be done at the shorter end of that time period. The pieces should be slightly crisp, lightly browned, and fork-tender when done.
Notes
Most of the recipes here are based on a 1 pound portion for 4 people. However, broccoli is the exception to that.Pretty much everyone I know loves roasted broccoli and I just don't think you can cook too much of it most of the time. When I cook 2 pounds of broccoli, my family of 5 easily polishes that off. I often cook even more than that amount.
