Preheat a convection or conventional oven to 375°F (190°C).
Place the bread cubes into a large stainless steel mixing bowl.
Drizzle the extra virgin olive oil over the bread cubes and toss vigorously to ensure even distribution.
Sprinkle the salt, garlic powder, black pepper, and Italian seasoning over the oiled bread and toss again.
Spread the seasoned cubes in a single layer on a rimmed baking sheet lined with parchment paper.
Bake for 12 to 15 minutes, rotating the pan and tossing the croutons at the 7-minute mark to ensure uniform browning.
Remove from the oven when the croutons are golden brown and firm to the touch.
Allow to cool completely on the baking sheet to facilitate moisture evaporation and maximize crispness.
