1. In a large mixing bowl, proceed to whisk together two tablespoons of olive oil, ¾ teaspoon of kosher salt, ½ teaspoon of dried thyme, ¼ teaspoon of garlic powder, and ¼ teaspoon of black pepper.
2. Half a cauliflower head and remove the rough core. Proceed to cut the florets into 1 – 1½ inch pieces, i.e., 6 to 7 cups.
3. Then go ahead and toss them in the basin until everything is equally coated.
4. You can now preheat the air fryer to 400 degrees Fahrenheit. In the basket or tray of a five ½-quart or larger air fryer, proceed to arrange the cauliflower florets in an equal layer.
5. Go on and air fry for 15 minutes – flipping every 5 minutes – until the cauliflower is soft with browned and crispy edges.

Thanks to the air fryer, they come out wonderfully crispy on the outside and soft and tender on the inside without becoming mushy. The cauliflower is “fried” in the air fryer using circulating air. It’s a countertop convection oven, essentially.
