Preheat your oven to 375°F. Grease a baking sheet or line it with parchment paper.
Finely chop the steamed broccoli. You can use a food processor for a finer texture.
In a large bowl, combine the chopped broccoli, cheddar cheese, breadcrumbs, Parmesan cheese, eggs, garlic powder, and pepper. Mix until well combined.
Using your hands, ice cream scoop, or a spoon, form the mixture into bite-sized balls or small patties.
Place the broccoli bites on the prepared baking sheet, making sure to leave some space between each.
Bake in the oven for about 15-20 minutes or until the bites are golden brown and cooked through.
Allow the broccoli bites to cool for a few minutes before serving.
