Place the frozen Texas toasts in the air fryer basket and spread in an even layer (make sure they aren't overlapping). No oil spray is needed.
Air Fry at 340 °F for about 7-10 minutes, or until the cheese is golden and the toast is heated through.
If you’re cooking only 1-2 pieces it might take about 5-6 minutes. Timing will also depend on how crisp you like your toast, the type of cheese, how thick the toast is, etc. Test a piece first and you’ll know more of what your preferred timing is like for your particular frozen cheese toast.
