Put the ground beef in the air fryer basket. Break it into small pieces and spread them out evenly. Sprinkle the salt on top.
Preheat the air fryer to 400 degrees and cook the ground beef for 4 minutes.
After 4 minutes, open the basket, stir, and break up the beef some more.
Cook for another 2-3 minutes.
Scoop out the beef from the basket, and if there's any fat, pour it out. Enjoy!
