Gather any bits of stale bread you may have. Break or cut them into small pieces (about the size of croutons). If you have fresher bread that isn't quite stale, you can add that too. Cut or tear it up. To make 3 cups of breadcrumbs you will need about five handfuls of bread.
Arrange all your bread pieces on a large baking sheet. Bake in a warm oven 325 F, for 10-15 minutes to dry out fresher bread and take any moisture from the stale bread.
When your bread pieces are dry and hard, remove them from the oven.
Using a food processor, pulse the bread pieces in small batches.
To season the breadcrumbs:
Measure out about three cups of your breadcrumbs. If you have more than three cups or less then three cups, please just adjust the seasonings accordingly. It does not have to be exact. These ratios are merely guidelines.
In a medium bowl, mix the breadcrumbs with the seasonings and spices.
Store in an airtight container in the fridge or freezer. I do not recommend storing these on the shelf as they do not contain preservatives and may mold.
You can use these breadcrumbs in many recipes including meatballs, meatloaf, salmon cakes, stuffed vegetables, over pasta, over eggs, and much more.
