In a small mixing bowl, combine the spices and oil. Mix well, getting rid of any spice clumps. You want a smooth "sauce" consistency.
Put the bread cubes in a large mixing bowl, drizzle the oil over the bread, and stir until the bread is evenly coated in oil.
Spread the croutons out over a parchment-lined cookie sheet making sure you have an even, single layer of bread so they can bake evenly.
Bake at 300 F. for 25-30 minutes or until they are golden brown and slightly crunchy.
Set the sheet on a heat-safe surface and allow the croutons to cool completely.
Place the croutons in an air-tight container and store in the fridge or freezer until you're ready to use them!
