Start by washing and chopping the broccoli into bite-sized pieces.
Remove any tough stems.
In a large microwave-safe bowl, combine the broccoli with olive oil, minced garlic, red pepper flakes, salt, and black pepper.
Toss to coat the broccoli evenly.
Cover the bowl with a microwave-safe lid or plastic wrap.
Microwave the broccoli on high for 1 minute and 45 seconds.
After microwaving, carefully remove the cover, being mindful of the steam.
Stir the broccoli to ensure even cooking.
Sprinkle grated Parmesan cheese over the hot broccoli.
Toss again to combine flavors.
