Here's another tip that's so simple it shouldn't even count as a tip. Next time you find yourself needing bread crumbs for a recipe, you'll be ready. Remember those pesky bread heels that you only eat begrudgingly (if at all)? How about that lonely piece that doesn't have a partner to make a sandwich out of? Well next time you get down to those odd last pieces, turn them into freezer breadcrumbs to have on hand for any occasion.
Break them into fourths
Throw them into a food processor until fine
Stick the crumbs into a Ziploc bag labeled with the date
Lay flat in the freezer
Next time your recipe calls for bread crumbs...
Pull out as much as you need
Mix in herbs, Parmesan cheese, olive oil, or whatever seasoning you want
Sprinkle them on and bake/broil according to the recipe.
Shouldn't I toast them beforehand? Not necessary since you normally cook food with the breadcrumbs on it anyway, so they'll have a chance to get nice and crispy. This is fast, easy, and convenient. Plus they won't go bad for... a long time.
