Turn on the broiler to high.
Tear or cut sourdough bread into 1 ½ to 2-inch pieces and place in a large bowl.
Drizzle olive oil over the bread and then sprinkle with herbs. If you are making garlic croutons, add the garlic to the olive oil before pouring over bread cubes.
Season with a pinch each of salt and pepper.
Toss to distribute the oil and seasonings.
On a baking sheet, spread bread cubes in a single layer and broil until the croutons are browned; toss once or twice to brown all sides. Note: You’ll need to keep an eye on these as they broil, as they could burn quickly.
Remove when croutons are golden and toasted on the outside while still tender on the inside.
