Preheat oven to 375 F and line two baking sheets with parchment paper.
Cube day or two old bread into equal size cubes and place in a big bowl. Yes, keep the crusts, that's the best part!
Melt butter. Add olive oil, pepper, salt, garlic powder, onion powder and parsley,whisk
Pour butter mixture over cubed bread and toss in the bowl until all the bread is well coated.
Place onto a parchment lined baking sheets and spread out evenly. Allow room for air to circulate around the cubes. If you crowd them they will just sweat and not dry out.
Bake until crispy, stirring every so often – about 20-30 mins, total time depends on how dry your bread is to start.
