1. Sun Drying

Sun drying is a traditional and natural method for drying oregano leaves and other herbs. So, after harvesting this herb from your garden, clean it thoroughly and spread the leaves in a single layer on a surface in a sunny, well-ventilated area.

Ensure the herbs are exposed to direct sunlight, which helps evaporate moisture quickly. Turn the leaves occasionally to ensure even drying, as it can take 1-2 days. Once the oregano is crispy and brittle, it can be stored in an airtight container.

2. Salt Drying

Drying oregano with salt is an effective method for drawing out moisture and preserving herbs for a long time. This method can be particularly useful in humid climates where other drying methods may be less effective.

To use this method, simply spread a layer of coarse salt on a shallow dish or tray. Then, place oregano leaves on top of the salt, ensuring they are not overlapping. Gradually, add another layer of salt on top of the oregano leaves, covering them completely.

3. Air Drying

To air dry oregano, gather the stems and tie them together using a string or rubber band and hang the bunches upside down in a well-ventilated, dry area away from direct sunlight.

For maximum efficiency, a cool, dark space with good airflow, such as a room with a ceiling fan or a covered porch, works well. Ensure the area is free from moisture and pests to prevent mold growth. Depending on humidity and airflow, this process typically takes 1-2 weeks.

4. Oven Drying

To use this method, preheat your oven to its lowest temperature setting, typically around 140-150°F (60-65°C). Spread oregano leaves in a single layer on a baking sheet, making sure they are not overlapping to ensure even drying.

Then, place the baking sheet in the oven, leaving the oven door slightly ajar to allow moisture to escape and prevent the oven from getting too hot. As this whole process usually takes 1-2 hours, check the leaves every 30 minutes, turning them occasionally to ensure even drying.

5. Use an Airfryer

After learning how to dry oregano in oven, you can also learn to dry it using an air fryer machine. To do so, preheat the air fryer to a low temperature, around 100-120°F (38-49°C). Rinse and thoroughly dry the oregano leaves, then spread them in a single layer on the air fryer basket or tray, avoiding overlap.

Place the basket in the air fryer and set the timer for 10-15 minutes, checking every 5 minutes and shaking the basket or turning the leaves for even drying. Once they are brittle, remove them and let them cool completely before storing them in an airtight container away from light and heat. 

6. Hanging in a Paper Bag

Hanging oregano in a paper bag is a straightforward method. Therefore to begin this process, gather the oregano stems and place them inside a brown paper bag. Tie the top of the bag closed with a string or rubber band, leaving a small opening to allow air circulation.

Next, hang the bag in a dry, well-ventilated area away from direct sunlight for 1-2 weeks. The paper bag protects the herbs from dust and insects while allowing moisture to escape.

7. Use a Dehydrator

To dehydrate oregano using a dehydrator, start by rinsing the oregano leaves and patting them dry with a paper towel to remove excess moisture. Then, arrange the leaves in a single layer on the dehydrator trays, ensuring they are not overlapping to allow for proper airflow.

Set the dehydrator to the herb setting or around 95°F (35°C), and let it run for 4-8 hours, depending on the humidity and the specific dehydrator model. Check the oregano periodically, and rotate the trays if necessary to ensure even drying.

8. Microwave Drying

To use this convenient method, spread the oregano leaves in a single layer between two paper towels or on a microwave-safe plate. Microwave the leaves on low or medium power for short intervals, typically 1 minute at a time.

After each interval, check the leaves and stir or flip them to ensure even drying. Continue microwaving in 30-second to 1-minute increments until the leaves are dry and crisp. Be cautious not to overheat them, as this can affect their flavor and quality.

9. Using a Fan

To do this, spread the oregano leaves in a single layer on a clean cloth or a mesh screen to allow air to flow freely around them. Place the cloth or screen in front of a fan, ensuring that the leaves are well-ventilated.

Then, turn on the fan to circulate air over the oregano, which helps evaporate moisture more quickly. This method works best in a dry, warm environment and can take 1-2 days.

10. Drying with Frost-Free Refrigerator

A frost-free refrigerator is an effective method that utilizes the appliance's dry environment. To do this, wash and thoroughly dry the oregano leaves with a paper towel. Next, spread the leaves in a single layer on a baking sheet or clean cloth, without overlapping. 

Then, place the tray or cloth inside the refrigerator, ideally on a shelf with good airflow. This refrigerator's frost-free feature, which prevents ice buildup, helps maintain a dry atmosphere that aids in drying which usually takes 1-2 weeks.

How Long Dried Oregano Last?

When stored correctly, dried oregano can maintain its quality for about 1-3 years. To extend its shelf life, keep it in an airtight container placed in a cool, dark, and dry location, such as a pantry or cupboard, because exposure to light, heat, and moisture can degrade its flavor and potency over time.

Although dried oregano remains safe to use beyond this period, its aromatic qualities may diminish. 

Proper Storage Conditions

Proper storage conditions are crucial for maintaining the flavor and quality of dried oregano. Here are the key factors to consider:

• Airtight Container: Store dried oregano in an airtight container to prevent exposure to air, which can lead to loss of flavor and potency. Glass jars, plastic containers with tight seals, or vacuum-sealed bags work well.

• Cool, Dark Place: As light and heat can degrade the essential oils and color of the oregano, keep the container in a cool, dark location, such as a pantry or cupboard, away from heat sources like stoves or ovens. 

• Dry Environment: Ensure the storage area is dry, as moisture can cause the oregano to clump or develop mold. So, avoid storing dried oregano in humid environments.

• Avoid Frequent Opening: Minimize the container's opening frequency to prevent exposure to air and moisture.

Potency Check

To check the potency of dried herbs, follow these steps:

• Visual Inspection: Examine the dried oregano for any signs of discoloration or mold. It should be a consistent green color without any dark spots or unusual growths.

• Aroma Test: Rub a small amount of the dried oregano between your fingers to release the essential oils. Take a sniff to assess the aroma. Fresh, adequately stored oregano should have a strong, pleasant herbal scent. If the aroma is weak, stale, or off, it may indicate that the oregano has lost its potency.

• Taste Test: If the herb passes the visual and aroma tests, you can taste a small amount. The flavor should be recognizable and robust. However, if it tastes bland or different from what you expect, it might have lost its flavor over time.
