Preheat oven to 375°F.
Place the bread pieces in a large bowl. Set aside. In a small saucepan, heat the olive oil with the garlic over medium-high heat until the garlic turns golden and becomes fragrant. This should take about 4-5 minutes. Make sure the garlic does not burn or it will taste bitter. Remove the garlic cloves from the oil by straining or picking them out and discarding or saving for another use.
Drizzle the garlic oil over the bread crumbs and toss to coat. Add 2 tablespoons Parmesan cheese, toss again and season with salt and pepper.
Arrange without overlapping on a baking sheet with a rim. Bake for 15 minutes, stirring and flipping them occasionally.
Remove from oven and return to the bowl, tossing again with 2 tablespoons of Parmesan cheese and the parsley. Allow to cool.
Store in an airtight container for up to 2 weeks.
