Step 1

Set the oven rack to the center position. Preheat to 300ºF (149ºC).

Step 2

Add cubed bread into a food processor. Process on high speed for 30 seconds for coarse bread crumbs, or 1 minute for fine bread crumbs.

Step 3

Transfer to a large sheet pan or two small pans. Spread evenly in a single layer in the pan.

Step 4

Bake for 5 minutes, stir and then bake another 5 minutes. The bread crumbs should be lightly browned and feel dry to the touch.

Step 5

Bake another 2 to 5 minutes as needed to make to completely dry.

Step 6

Allow bread crumbs to cool on the sheet pan for 10 to 15 minutes.

Step 7

Transfer to an airtight container to store.

Step 8

For even finer bread crumbs, add to the food processor and pulse until the desired size is reached.
