Preheat the oven to 180 °C (350 °F).
Cut fresh or stale bread into cubes of the desired size.
In a bowl, mix olive oil with minced garlic and the herbs and spices of your choice: dried herbs (dill, thyme, oregano, basil…), spices (cumin, paprika, Espelette pepper, black pepper…).
Add the bread cubes and gently toss to coat evenly. You can also cover the bowl with a plate and shake it in all directions to make sure the cubes are well coated.
Spread the bread cubes on a baking sheet lined with parchment paper in a single layer, making sure they do not overlap.
Bake for 20 to 30 minutes, until the croutons are golden and crispy. Stir once or twice during baking to ensure even browning and prevent burning.
Remove from the oven and let cool completely before storing in an airtight jar or container.
Croutons can be stored for up to 15 days if the jar is tightly closed after each use. Optionally, sprinkle with more Espelette pepper or Herbs de Provence after baking for extra flavor.
