Preheat air fryer to 380 degrees. (Still burning – maybe drop the temperature to 350 and cook longer. Some people say to add a couple of tablespoons of water in the bottom of the air fryer.)
Spray bottom of basket with olive oil.
Place frozen broccoli florets in basket.
Spray broccoli with olive oil. Sprinkle with garlic salt and pepper.
Roast for 10 to 25 minutes, shaking or stirring halfway through.
Notes
1) Do not thaw the broccoli. Put it into the air fryer straight from the freezer.
2) The more broccoli in the basket, the longer the required cook time.
3) The original recipe specified 400 degrees, but that burned the broccoli.
