How to Cook Buckwheat (3 ways)

  • Author: Lindsay Cotter
  • Total Time: 15 minutes
  • Yield: 1.5 to 2 cups cooked buckwheat 1x
  • Diet: Gluten Free


Now that you know what buckwheat is, learn how to cook it on the stovetop, in the Instant Pot, or with a slow cooker, too! It’s a nutrient-rich, gluten free grain that can be served with any meal! 


Units Scale
  • 1 cup buckwheat groats
  • 1 1/22 cups water or non dairy milk of choice (The liquid varies depending on the cooking method. See instructions.)


Stovetop Directions

Ratio of 1:1.5 – This means for every one cup of buckwheat groats, 1 1/2 cups of water are needed.

  1. Place the water in a saucepan over high heat, and bring it to a boil.
  2. Next, add the buckwheat groats and a small pinch of kosher or sea salt.
  3. Bring the contents to a boil again. Then, cover the pot, and reduce the heat to medium-low. Simmer for 10 to 15 minutes, or until the buckwheat groats are tender. Check for doneness after about 8 minutes. 
  4. Drain off excess water. 

Instant Pot Directions

Ratio of 1:1.75 – For one cup of buckwheat, 1 3/4 cups of water are needed. 

  1. For a warm cereal (porridge), substitute the same amount of milk or non-dairy milk for the water.
  2. Place the water/milk and groats into the Instant Pot. Manually set to cook at HIGH pressure for a cook time of 5 minutes.
  3. After 5 minutes, allow 8 -12 minutes of natural release before using quick-release to finish releasing the pressure.
  4. Drain off any excess water.

Slow Cooker Directions

Ratio of 1:2 – For one cup of buckwheat, 2 cups of water are needed.

  1. Place the buckwheat groats and water into a slow cooker.
  2. Cook on high for 2 hours (or until the groats are soft) or low for 4 hours.
  3. Drain off any excess water.


Cooking times vary with slow cookers, so be sure to check progress halfway through cooking
