Select and prep the shallots: Choose firm, dry shallots with tight skins. Avoid any with soft spots or sprouting. Peel off papery skins and trim root and tip ends.

Slice uniformly: Cut shallots into thin, even slices, about 1/8 inch (3 mm). Uniform thickness ensures they dry at the same rate and prevents burnt edges. A mandoline helps.

Optional quick soak: If you find shallots too pungent, soak slices in cold water for 5 minutes, then pat very dry. Excess moisture will prolong drying, so dry them well.

Arrange for dehydrating: Spread slices in a single layer on dehydrator trays or on parchment-lined baking sheets if using an oven. Leave space between pieces for airflow.

Dry in a dehydrator: Set to 125–135°F (52–57°C). Dry for 6–10 hours, rotating trays as needed. They’re done when pieces are brittle and snap cleanly with no chewiness.

Or dry in the oven: Set the oven to its lowest temperature (ideally 170–200°F / 75–95°C). Prop the door slightly open with a wooden spoon for airflow. Dry 3–5 hours, checking and stirring occasionally until crisp.

Cool completely: Let dried shallots cool to room temperature. This prevents residual heat from creating condensation in your grinder or storage jar.

Grind: Use a spice grinder, high-powered blender, or mortar and pestle. Pulse to your desired texture. For fine powder, work in small batches and sift, regrinding larger bits.

Optional seasoning: Stir in a tiny pinch of fine sea salt or a whisper of citric acid to lift the flavor. Keep additions minimal so the powder remains versatile.

Package: Transfer to an airtight, lightproof container (amber glass jar or a sealed tin). Label with the date. For the best texture, add a food-safe desiccant packet.
