Simple Storage Hacks for Thyme and Oregano

Thyme and oregano stay fresher longer with proper care techniques suited to their type. However, fresh and dried herbs will have different ways to store.

Make sure you take note them!

Fresh Thyme and Oregano

  • Wash First: Rinse your thyme and oregano gently to remove any bacteria or dirt.
  • Dry Carefully: Lay the herbs on a paper towel, then roll the towel around them gently.
  • Store Properly: Place the rolled herbs inside a plastic bag or wrap them before putting them in the fridge.

When stored this way in a good fridge, fresh thyme and oregano can stay fresh for up to 2 weeks.

Dried Thyme and Oregano

  • Check for Complete Dryness: For homemade dried herbs, rub the leaves between your fingers - if they feel crispy, they are fully dried.
  • Use Airtight Containers: Store dried herbs in airtight jars or containers with lids. Avoid plastic containers because they may release chemicals.
  • Store in a Cool, Dry Place: Keep dried herbs away from moisture, heat, and direct sunlight. A pantry or closed cabinet works best.
  • Label Your Herbs: Write the date you made or bought the dried herbs to keep track of freshness.

Properly stored dried herbs can last 1 to 3 years without losing flavor.

Thyme or Oregano? The Herb Swap You Need to Know

Thyme and oregano share similar minty, earthy flavors, making them excellent stand-ins for each other in a simple 1:1 swap. When trading dried for fresh versions between these herbs, cut the amount in half since dried herbs pack more punch - just use half a teaspoon of dried oregano instead of a full teaspoon of fresh thyme.

This reduction helps maintain balance in your dish and prevents any overwhelming tastes. The swap works both ways for most cooking needs, though not all thyme varieties play nice with oregano recipes.

Only English and French thyme make good substitutes for common oregano in most dishes. Most recipes turn out great with this herb exchange once you understand these basic proportions.
