Technically yes, but it's not our top recommendation. Raw shrimp cooks so quickly, while pre-cooked shrimp will turn rubbery so quickly. We honestly rarely recommend using pre-cooked shrimp for most of our recipes, unless it's a cold recipe, that is! If you must use cooked shrimp, add to the skillet after broccoli is cooked, cover, and allow to cook for an additional 2-3 minutes. You will definitely need to season the sauce and broccoli more heavily if you go this route, as the shrimp will not have any seasoning on it.
