Preheat the oven to 350 degrees.
Line a baking sheet with foil.
In a medium bowl, toss the breadcrumbs and oil together until the oil is coating all the breadcrumbs.
Add the garlic, garlic salt, rosemary and pepper and stir everything together.
Spread the mixture on the baking sheet in a single layer and bake for 5-8 minutes until the breadcrumbs are golden brown.
Let the breadcrumbs completely cool and add to an airtight container. Store in the fridge for up to one week.
Add to salads, soups, vegetables and pasta. Enjoy!
