What Are Sourdough Croutons?
Sourdough croutons are small, toasted cubes of bread made from sourdough bread.
Sourdough bread is a type of naturally leavened and fermented bread that is made from a sourdough starter. The wild yeast and bacteria in the starter give sourdough bread its uniquely tangy flavor.
Croutons made from sourdough bread are a popular addition to salads, soups, casseroles, and more.
Are Sourdough Croutons Healthy?
Homemade sourdough croutons are healthier than store-bought croutons because they're made without preservatives or added sugar. When you make croutons at home, you have complete control over the ingredients that go into them.
Plus, sourdough bread is also thought to be easier to digest than other types of bread because of the slow fermentation process it goes through before baking.

Here are some notes on any special equipment I used to make this recipe.
- Serrated Knife- A serrated bread knife makes quick work of sourdough bread and is the best knife to cut bread with.
- Rimmed Baking Sheet- A large, rimmed baking sheet is ideal for making homemade croutons. It allows you to spread the croutons out evenly without worrying about them falling off the edge.

How to Make Sourdough Croutons
Here is how to make sourdough croutons in the oven.
Step 1: Cube the sourdough bread. Preheat oven to 325°F and line a rimmed baking sheet with parchment paper. Cut the loaf of sourdough bread into ¾-inch cubes using a serrated knife.
Step 2: Season the croutons. In a large bowl, toss the sourdough bread cubes with olive oil and seasonings. Arrange the seasoned bread pieces in a single layer on the prepared parchment-lined baking sheet.
Step 3: Bake the croutons. Bake the croutons for 20-25 minutes or until they are golden brown and crispy. Be sure to check them frequently to avoid burning.
Step 4: Cool and store. Remove the baking sheet from the oven and allow the croutons to cool completely. They will continue to crisp up as they cool. Store the croutons in an airtight container at room temperature for up to one week.
Tips for Success
- Use stale bread. The best bread for making croutons is stale bread, which is easier to cut and will absorb the seasonings and oil better. If your sourdough bread is very fresh and soft, leave it out on the counter for a few hours or overnight to dry it out before making the croutons.
- Cut the bread into equal-sized pieces. This will ensure that the croutons bake evenly and have a consistent texture.
- Don't overcrowd the baking sheet. Be sure to arrange the bread cubes in a single layer on the baking sheet so they cook evenly and become crispy.
- Watch the croutons carefully. Keep an eye on the croutons while they are baking to ensure that they don't burn. They can go from golden brown to burnt very quickly.
- Allow the croutons to cool completely. If you're planning to store the croutons, it's important they are completely cooled so they don't become soggy.
How to Scale This Sourdough Crouton Recipe
This recipe makes approximately 6 cups of sourdough bread croutons from a one-pound loaf of sourdough bread.
However, it's super flexible and easy to scale the recipe up or down to meet your needs. As a family of two, I often make just a half or quarter batch for my fiancé and me. I've also tested making a double batch for a crowd and it works well.

To ensure that your croutons are crispy, make sure to bake them in a single layer on a baking sheet and don't overcrowd them. Additionally, using stale sourdough bread helps croutons dry out faster during baking.
