To make homemade croutons: Cut the bread into cubes. Season with salt and pepper and drizzle some olive oil on them. You can air fry them at 400°F (200°C) for about 6-7 minutes until golden, shaking the air fryer basket a couple of times. Or bake them at 425°F (220°C/200°C fan) until golden (about 8-10 minutes). For added flavor, grate some parmesan on top of them while they’re still warm.
