Slideshow: How to Make Your Own Breadcrumbs

Step 1
Step 1
Start with a day-old loaf (it's a bit firmer and drier when it's not perfectly fresh) or a few leftover slices of white, wheat, semolina, or corn bread.
Step 2
Step 2
Cut the bread into small pieces that can break down easily in a food processor. Don't overstuff the bowl. Leave the crusts on for extra crunch and color, or discard as desired.
Step 3
Step 3

Step 5
Step 5
Spread crumbs onto a rimmed baking sheet and place in a pre-heated 250°F oven for 25 minutes.

Alternate option: Toast them lightly in oil or butter in a cast iron pan.

This is my method—it gives me time to prep some other ingredients for the meal—but you can speed up the process by using a 375°F oven for 10 minutes, or slow it down using a 200°F oven for up to an hour. Just be sure you don't take the toasting too far.
