You can use fresh or frozen brussels sprouts for this recipe. If using frozen, I generally buy the 12 ounce package that is available from my local grocery store. Frozen brussels sprouts are easier to make because they eliminate the washing, trimming and steaming process, but the fresh ones do turn out crispier. I make this recipe both ways, depending on what I have on hand.
