In a medium bowl, combine garlic and oil. Set garlic steep for 30 minutes.
Preheat oven to 350 degrees F. Line a baking sheet with a silicone mat.
Cut bread into 1/2-inch pieces and place in a large mixing bowl.
Strain garlic from oil and pour oil over bread. Add 1/2 the garlic the oil to the bowl. Season with Parmesan cheese, basil, oregano, paprika, pepper, and salt. Stir with a large spoon until bread cubes are well coated and seasonings are evenly distributed.
Pour bread cubes onto prepared baking sheet and spread into a single layer. Bake for 15 minutes, and then stir croutons. Bake for another 15 minutes, and then group the croutons together so they're touching. Bake for another 10 minutes.
Remove croutons from the oven and let cool to room temperature before serving.
