Wash the cauliflower thoroughly and drain excess water.
Remove the stems and cut the florets away from the stem. Break up the florets into 1 to 1 1/2 inch pieces.
In a large bowl, toss the cauliflower florets with 1 tbsp vegetable oil, 1 1/2 tsp curry powder, and 1/2 tsp salt until well coated.
Arrange the seasoned cauliflower in a single layer in the air fryer basket.
Air fry the cauliflower at 375 degrees F for about 12-14 minutes, or until tender and crispy.
Taste the cauliflower and season with additional salt if necessary before serving. Squeeze a little lemon juice on it after air frying for extra flavor.
