Remove any really loose leaves from the outside of the cabbage. Make a clean slice off of the root end. Then turn that flat end onto your cutting board. This will give stability while cutting the steaks. Now slice the cabbage in half. While the cabbage is still standing on the flat end, continue to slice outward from the middle into ¾ to 1-inch steaks.

Add the olive oil and vinegar into a small bowl and stir.

Add the garlic powder, onion powder, kosher salt, cracked black pepper, and smoked paprika to a small bowl. Stir to mix.

With your cabbage steaks now lying flat on a sheet pan or cutting board, use a pastry brush or a spoon to spread the olive oil mixture over both sides of the cabbage steaks. (turn the steaks over, gently holding the sides together as you turn).

Now sprinkle about 1½ teaspoons of the spice mixture on one side of the cabbage. Make sure to get it all along the edges. You can use a spoon or use your fingers to sprinkle the seasoning onto the cabbage steak.

Lightly spray the air fryer basket with olive oil spray or avocado cooking spray.

Gently place the cabbage steak into the air fryer basket with the season side up. (If your cabbage steaks are a bit wide, you may need to cook the cabbage steaks in batches) Cook at 360°F for 12-15 minutes. Check them at 12 minutes to check for golden brown edges. Depending on how thick you cut your steaks, you can continue to cook in 2-minute increments, checking at the end of each cook time.

Remove cabbage steaks from the air fryer using a spatula and garnish with the chopped parsley.

Optional: You can brush a little more olive oil on the cabbage steaks after removing them from the air fryer.
