Step 1: Tear the stale bread into smaller pieces to prepare for processing.

Step 2: Place the bread pieces into a food processor and pulse until they form coarse crumbs.

Step 3: While pulsing, add the garlic powder, dried oregano, dried basil, salt, and black pepper to the crumbs.

Step 4: With the processor running, slowly drizzle in the olive oil until the crumbs are evenly coated.

Step 5: Heat a large skillet over medium heat and add the breadcrumb mixture; cook, stirring frequently, until golden brown, about 5 to 7 minutes.

Step 6: Remove the skillet from heat and transfer the toasted breadcrumbs to a plate; let them cool completely to prevent sogginess.

Step 7: Store the cooled breadcrumbs in an airtight container at room temperature for up to one week.

Step 8: For longer storage, place the cooled breadcrumbs in a freezer-safe bag and freeze for up to three months.
