How to Dry Fresh Rosemary at Home

Drying rosemary doesn’t require any fancy equipment—just time and care. Here are three simple methods:

1. Air-Drying Method

  • Rinse and pat dry the rosemary sprigs thoroughly.
  • Tie them into small bundles using twine or rubber bands.
  • Hang the bundles upside down in a warm, dry, well-ventilated area away from direct sunlight.
  • Leave for 1–2 weeks until the leaves become crisp and break easily.

2. Oven-Drying Method

  • Preheat your oven to its lowest setting (around 150°F / 65°C).
  • Spread clean, trimmed rosemary sprigs in a single layer on a baking sheet lined with parchment paper.
  • Bake for 1–2 hours, checking every 20 minutes to avoid burning.
  • Let cool completely before storing.

  • Set the temperature to 95–115°F (35–45°C) and dry for 2–4 hours.
  • Store once fully dried and cooled.

Storage Hacks That Keep Dried Rosemary Fresh

Once dried, proper storage is key to preserving flavor and preventing moisture damage.

  • Strip the leaves from the woody stems after drying.
  • Store in an airtight glass jar or spice container.
  • Keep in a cool, dark place—like a pantry or cabinet—to prevent light degradation.
  • Add a silica gel packet to absorb moisture if storing long-term.
  • Label jars with the date and contents for easy identification.
