Place 1 large head chopped broccoli in a microwave-safe bowl.
Add 3 tablespoons water to the bowl.
Cover the bowl with a microwave-safe plate.
Microwave on high for 2 1/2 to 4 minutes, until the broccoli is tender when pierced with a fork.
Using oven mitts, carefully remove the bowl from the microwave and lift the plate away from you to avoid steam. If there is standing water in the bowl, drain or pour it off.
If desired, add 1 tablespoon salted butter and toss the broccoli to coat evenly.
