Steam the broccoli florets until tender, then chop them finely and let cool.
In a mixing bowl, combine chopped broccoli, eggs, cheddar cheese, almond flour, Parmesan, green onions, garlic, salt, and pepper.
Mix well until the mixture holds together. If it feels too wet, sprinkle in a little more almond flour.
Shape the mixture into small patties about the size of your palm.
Heat olive oil in a skillet over medium heat. Place patties in the pan without crowding.
Cook each side until golden brown and crisp, about 3–4 minutes per side.
Transfer to a paper towel–lined plate to drain any excess oil and serve warm.
