Cut the bread into slices, around 2 inches thick.

Add the butter to a small bowl. Add the minced garlic and parsley to the bowl.

Use a fork to mash the mixture until you have a spreadable mixture and the ingredients have melded into the butter.

Evenly spread the butter over one side of the bread slices.

Sprinkle each slice with the cheese if using.

Place the slices of buttered bread on the tray in the air fryer basket. Do not overcrowd the basket.

Cook for 5 minutes at 200°C (395°F).

Once the first batch is cooked, keep them warm by placing them on a plate and covering it with foil.
