Frequently Asked Questions About Sourdough croutons

What are sourdough croutons made of?

Sourdough croutons are bite-size pieces of sourdough bread toasted until crisp. They’re often tossed with oil and seasonings, though plain versions are also common, and the bread gives them a tangier flavor than many standard croutons.

How do you make sourdough croutons from scratch?

To make sourdough croutons, cut sourdough bread into cubes, toss them with a little oil and seasoning, and bake until crisp and browned. Spread the cubes out so they toast rather than steam, and let them cool before serving.

What can you use sourdough croutons for?

Sourdough croutons are a crunchy topping for salads and soups. They also work as a garnish for roasted vegetables or as a crunchy element in a bread-based salad; add them just before serving to keep their texture.

How do you keep sourdough croutons crispy?

Keep sourdough croutons crispy by cooling them completely and storing them in an airtight container in a dry place. Trapped warmth creates moisture and softens them; if they lose their crunch, briefly re-toast them in the oven.

Can you make sourdough croutons in an air fryer?

Yes, sourdough croutons can be made in an air fryer. Toss the bread cubes lightly with oil, arrange them in a single layer, and cook until crisp, shaking the basket so they brown evenly.

Can you make sourdough croutons in a skillet?

Yes, you can toast sourdough croutons in a skillet with a little oil. Stir the cubes often over medium heat, and cook in batches if needed; overcrowding makes them brown unevenly and can leave some sides soft.

Are sourdough croutons different from regular croutons?

Yes, sourdough croutons are made from sourdough bread, which can give them a tangier flavor and a chewier interior beneath the crisp exterior. Their taste and texture still vary with the loaf and how they’re seasoned and toasted.

Can you make sourdough croutons with stale bread?

Yes, stale sourdough bread is a good choice for sourdough croutons because it is already drier and toasts readily. Cut away any moldy portions and season the cubes before baking so the flavor coats them evenly.

Can sourdough croutons be frozen?

Yes, sourdough croutons can be frozen in a sealed container, though freezing may soften their crunch. Reheat them from frozen in the oven until crisp again, then let them cool briefly before adding them to a dish.

Why are my sourdough croutons chewy instead of crunchy?

Sourdough croutons usually turn chewy when they haven’t dried out fully or have absorbed moisture after baking. Toast the cubes until crisp throughout, cool them uncovered, and store them airtight only once they are completely cool.

What is Sourdough croutons?

Sourdough croutons are cubes of sourdough bread toasted in the oven or a pan until crisp. Their tangy, fermented flavour comes through beneath the browned, savoury edges, and they’re also a handy way to use up day-old bread.

They’re commonly scattered over salads or added to soups, where they bring crunch and soak up some of the broth or dressing. Mostly made of bread, they are rich in carbohydrates, with some protein and fibre; at 407 calories per 100 g, a small topping is usually plenty. For a lighter batch, toast the cubes with just a little oil, or use them to add texture to a vegetable-rich meal.
