Learn how to make Thai Chili Flakes (Prik Bon) with these ultra-easy steps using only one ingredient! Customize it with your choice of dried peppers and control the chili spice level to your needs when making it from home!


  • 1/2 cup Thai dried chilis
  • There are many types of Thai peppers used in Thai cooking.  You can make Thai chili flakes using dried peppers such as Thai spur chilis (Prik Chee Fah)Thai bird's eyes chilis (Prik Kee Noo), or Thai Jinda peppers. 


  1. On medium how heat, toast the chilis in a hot pan for 5-6 minutes or until the peppers start to turn a little dark color and the fragrance fills your kitchen.
  2. Turn the fan on to avoid coughing and sneezing due to released oils.  High heat is not recommended for toasting chilis.
  3. Remove the peppers from the pan to a plate and cool before grinding. Once cooled, place the peppers in a spice grinder and grind to the flake size.
  4. Ground a few extra seconds for a fine chili powder form. If making fine chili powder, strain it through a small fine mesh strainer to remove big pieces.

If using a mortar and pestle, pound away the peppers until the desired size.


  • Use gloves to protect your skin when handling hot peppers.
  • If using a spice grinder, leave the pepper whole rather than breaking them up. The large, chunky pieces will help the blades pick up the pieces for grinding better than the small pieces. 
  • A small food processor will not work well for grinding a small amount of chili flakes unless you are making a huge batch of 2+ cups.
  • Experiment with Different Thai Peppers. Use various Thai peppers to explore diverse flavors and spice levels.
