Step-by-Step Process
Step 1: Selecting & Preparing Onions
Choose high-quality onions-fresh, firm and free from soft spots. Remove outer skins, rinse well and pat dry completely.
Step 2: Slicing
Cut onions into even slices, about 1/8–1/4 inch thick, using a knife or mandoline. Uniform thickness ensures consistent drying.
Step 3: Optional Pre-Treatment
Blanch onion pieces for 30 seconds in boiling water to help preserve color and flavor-especially if long-term storage is planned.
Step 4: Arrange on Dehydrator Trays
Spread pieces in a single layer without overlapping to allow proper air circulation.
Step 5: Dehydrate
Set dehydrator at 125–135°F (52–57°C) and dry for 8–12 hours, checking after 6 hours. They should become brittle and break easily.
Oven Method
Set oven to its lowest temperature (around 140°F / 60°C), place onions on lined trays and prop door open slightly. Dry for 6–10 hours, stirring occasionally.
Step 6: Cooling
Let the flakes cool fully at room temperature to remove any trapped moisture.
Step 7: Storing
Transfer cooled dehydrated red onion flakes into airtight jars or vacuum bags.
Store in a cool, dark, dry place for 6–12 months.
