Cut the ends of the brussels sprouts and remove any outer discolored or shriveled leaves. Cut each brussel in half and place in a bowl

Add 2 tablespoons of parmesan cheese, olive oil, garlic powder, salt, and pepper to the brussels sprouts and toss to combine

Place the brussels into the air fryer basket and air fry at 400 degrees for 7-10 minutes, checking to toss every two minutes, until they start to get crispy on the edges

Remove and sprinkle on the remaining ½ cup of fresh grated parmesan cheese over the top of the brussels sprouts. Do not stir after adding the cheese.

Turn the air fryer down to 375 degrees and air fry for 3-4 minutes, until the cheese is all melted over the brussels sprouts and the edges are golden brown

Serve immediately
