Preheat the oven to 375 degrees and line baking sheet with parchment paper.
Combine bread cubes, olive oil, Italian herb seasoning, salt and pepper. Toss in a large bowl or plastic bag until bread cubes are evenly coated in olive oil and seasoning.
Spread bread cubes onto baking sheet and bake until golden brown (approx. 15-20 minutes), turning once halfway through so that both sides are cooked evenly.
