Preheat the air fryer to 350°F (175°C) for 3-5 minutes until ready.
Slice the bread into ½ inch (1.25 cm) thick pieces evenly to ensure uniform cooking.
Mix softened butter, minced garlic, chopped parsley, and a pinch of salt for a smooth garlic butter spread.
Spread the garlic butter evenly on each bread slice, avoiding thick pools to prevent sogginess.
Arrange the bread slices in a single layer in the air fryer basket with space between each for proper air circulation.
Air fry at 350°F (175°C) for 4 minutes, then flip the slices and cook for another 2 minutes until the edges are golden and crisp while the centers remain soft.
