  • No equipment needed

Cons

  • Very slow (3-4 weeks)
  • Humidity ruins peppers

Method 2: Oven Drying

How It Works

Use your regular oven at very low temperature to dry peppers.

Best For

  • Small batches
  • People without dehydrators
  • Faster than air drying

Process

  1. Slice peppers in half or rings

Cons

  • Ties up your oven
  • Uses lots of energy
  • Uneven drying
  • Can cook instead of dry if too hot

Success tip: Use a wooden spoon to prop the door open for air circulation.

Method 3: Food Dehydrator

Electric dehydrator with controlled temperature and airflow.

Best For

  • Regular pepper drying
  • All pepper types

  • Testing pepper heat

Process

  1. Slice peppers thinly
  2. Place on microwave-safe plate
  3. Microwave 30 seconds at a time
