Cut 400 g bread into even cubes of about 1.5 cm. Use a sharp bread knife so the cubes don't get squashed.
Whisk 3 tbsp olive oil together with 1 tsp salt, 1 tsp garlic powder, 1 tsp dried oregano, 0.5 tsp black pepper and 0.5 tsp paprika in a large mixing bowl.
Toss the bread cubes thoroughly in the seasoned oil so every piece is evenly coated. Let them sit for a few minutes while the air fryer preheats.
Cooking in the air fryer
Preheat the air fryer to 180 °C convection.
Place the bread cubes in a single layer in the basket. Avoid overcrowding — work in two batches if necessary so they turn out crispy all over.
Cook for 6-8 minutes at 180 °C. Shake the basket halfway through so the croutons brown evenly. They should be golden and crispy, but not burnt.
Serving
Let the croutons cool slightly on a plate before scattering them over salad or soup, or serving them as a crispy side. They get even crispier as they cool down.
Notes
Tips for the perfect result:
Use day-old bread — it soaks up the seasoned oil better and turns out crispier than completely fresh bread. Always cut the cubes to an even size so they finish at the same time.Variation:
Experiment with rosemary, thyme, grated Parmesan or chilli flakes for different flavour profiles. Butter instead of olive oil gives a richer, fuller flavour.Serving:
Scatter the croutons over Caesar salad, tomato soup, Greek salad or pumpkin soup for extra crunch.Portion size:
If your air fryer is smaller, you can make the croutons in two batches — then they turn out more evenly crispy.
