Cut the broccoli into florets and wash them well.

Cook it for about 7 minutes at full power in the microwave in a steam-safe container, or boil it in a small pot with water until tender.

Drain the broccoli and chop it very finely, either with a knife or in a food processor.

Place it in a large bowl and add the salt, onion powder, flour, and the 2 eggs. Mix everything with a spatula.

Once well combined, add the shredded cheese and mix again.

To prevent sticking and for easy removal, place parchment paper at the bottom of the air fryer basket (leave the lower tray in place). Add spoonfuls of the broccoli mixture to form the burgers, flatten them a bit; it's okay if they are irregular in shape. Spray a little cooking oil on top.
