Cook the rice. Use your standard method (stovetop, rice cooker, or Instant Pot). Aim for slightly firm, not mushy. For long-grain rice, a 1:1.75 or 1:2 rice-to-water ratio usually works well.

Fluff and cool. When the rice is done, fluff it with a fork to release steam. Spread it on a large tray to cool until it’s just warm. This helps prevent clumping during drying.

Light seasoning (optional). If you want, sprinkle a little salt and gently toss. Avoid heavy oils or butter—they slow drying and can reduce shelf life.

Prepare dehydrator trays. Line trays with parchment or a mesh liner to prevent bits from falling through. Spread the rice in a thin, even layer, about one grain deep if you can.

Dehydrate. Set your dehydrator to 135–145°F (57–63°C). Dry for 4–6 hours, stirring once or twice to break up clumps. The rice is done when the grains are hard, dry, and brittle.

Oven option. If you don’t have a dehydrator, use your oven at its lowest setting (usually 170–200°F / 75–93°C). Prop the door slightly open to let moisture escape. Spread the rice thinly on lined baking sheets and dry for 2–4 hours, stirring every 30–45 minutes.

Cool completely. Let the rice sit at room temperature until fully cool. This prevents condensation once you store it.

Condition the batch. Place the dried rice in a large airtight container for 2–3 days, shaking it daily. If you see condensation or feel softness, return it to the dehydrator for another hour.

Package for storage. Move the finished rice to airtight jars, vacuum-sealed bags, or mylar bags with oxygen absorbers for long storage. Label with the date.

Rehydrate when needed. Combine 1 cup dried rice with 1 to 1 1/4 cups boiling water, cover, and rest 5–10 minutes. Fluff and season to taste. For stovetop, simmer gently until tender.
