Preheat your oven to 425 and line a baking sheet with aluminum foil. Rinse your sprouts.
Working one sprout at a time, cut off the tough end. At this point, you’ll probably notice some of the outer leaves begging you to pick them off. Do it. Just gently slip your fingers over the sprout and peel off anything that wants to come off. If the whole sprout is falling apart, toss it, but generally, you’ll get at least 2 leaves off of each sprout.
