Wash, hull, and slice the strawberries as thin and evenly as possible.
Spread slices in a single layer on dehydrator trays and make sure they don’t overlap.
Dry at 135°F (57°C) for 8 to 10 hours, depending on slice thickness and moisture level. The slices should feel crisp and completely dry.
Add the dried slices to a bullet blender and blend until smooth.
Spread the powder on a cookie sheet and let it air dry at room temperature for 24 hours.
Transfer to a clean glass jar with a tight-fitting lid. Keep in a cool, dry place.
