Homemade Dehydrated Garlic

Garlic can be preserved by drying and then ground into slices, flakes, granules, or powder. Each cut and grind gives you a slightly different flavor intensity and use.

Equipment

Ingredients
  

  • Fresh garlic bulbs (firm, with tight skin, no green sprouts)

Instructions
 

Prep & Cutting Options

  • Slices: Peel and cut cloves into ⅛” slices with a mandoline or sharp knife. Best for garlic chips, flakes, or grinding later.
    Minced: Finely chop or pulse in a food processor. Dries faster and makes chunkier bits.
    Purée: Spread a thin layer of crushed garlic on parchment or silicone liner. Once dry, break into shards and grind.
    Note: Thickness affects drying time — thinner dries faster but needs closer watching.

Dehydrator Method

  • Arrange garlic in a single layer on trays.
    Temperature: 125 °F (52 °C).
    Time:
    Slices: 8–12 hours
    Minced: 6–8 hours
    Purée: 4–6 hours
    Garlic is ready when it’s brittle and snaps cleanly (not bendy). Rotate trays if needed.

Oven Method

  • Slices: Store whole or crush lightly into flakes.
    Flakes: Pulse in a food processor or grinder for coarse texture.
    Granules: Use a spice/coffee grinder for a sandy consistency.
    Powder: Grind until very fine, then sift. Return larger bits to the grinder.

Best Tools for Grinding

  • Spice Grinder / Coffee Grinder: Best for granules and powder; produces consistent results.
    High-Speed Blender: Good for large batches; quickly reduces flakes to powder.
    Food Processor: Breaks slices into flakes or coarse granules.
    Mortar & Pestle: Great for small amounts and rustic texture.
    Manual Spice Mill: Load with slices for grinding fresh at the table.
    For ultra-fine powder: grind → sift → regrind larger bits until uniform.

Storage

  • Store in airtight jars, away from heat and light.
    For longest shelf life, use vacuum-sealed jars or add an oxygen absorber.
    Properly dried garlic can last 1+ years with flavor intact.

Preventing Clumping

  • Garlic powder naturally attracts moisture, which can cause clumping.
    Shake before use to loosen.
    Add helpers:
    A few grains of uncooked rice
    A couple of dried beans
    A food-safe desiccant pack (silica-free or clay-based for a natural option)

Yield (Approximate)

  • 1 lb fresh garlic ≈ 3–4 oz dried slices
    1 lb fresh garlic ≈ ½–¾ cup powder
