cut sourdough bread into small cubes. i like mine around 1/2".
drizzle olive oil evenly over the cubed bread. gently sprinkle a light, even amount of salt over cubed bread, and then top with whatever seasonings feel interesting to you.
you can combine the ingredients either first in a large bowl, or directly on the sheet pan. i hate doing dishes so i mix em up with my hands directly on the sheet. make sure the sheet pan is large enough as to not crowd the cubes.
bake for 15ish minutes, or until croutons are crisp and dry. keep an eye on them to prevent burning. eat them in soups, on top of salads, or straight up as a snack.
to store, wait until completely cool and keep in an airtight container for up to 2 weeks.
