In a mixing bowl, combine the softened butter, minced garlic, chopped parsley, Parmesan cheese, salt, and black pepper until smooth.
Evenly spread the garlic butter mixture over the cut sides of the bread.
Preheat the air fryer to 350°F (175°C) for about 3 minutes.
Place the bread in the air fryer basket, cut side up, and cook for 5–7 minutes until golden and bubbly. This method ensures perfect Air Fryer Garlic Bread every time.
Remove, cool slightly, slice, and serve warm.
