Can't find whole wheat bread crumbs at the store? No worries - they're SUPER easy to make! They're also a fantastic way to use up the heels of bread loaves, or the crusts if you're a homemade uncrustable maker like me!
Preheat the oven to 300°F. Place oven rack in the center position in the oven. Set a sheet pan aside.
Place cubed bread into food processor. Pulse for 30 seconds for coarser bread crumbs and 1 minute for finer bread crumbs.
Transfer bread crumbs to a large sheet pan and spread out into an even layer.
Bake for 5 minutes, stir, then bake another 5-10 minutes. Bread crumbs should feel completely dry when they are done, so continue baking another 2-4 minutes until they're dry to the touch.
Let bread crumbs completely cool on the rack.
If you want your bread crumbs even finer, process them again another 30-60 seconds once toasted and cooled.
Transfer to an airtight container to store.
