Place the oat groat kernels and water in a large crock-pot.
Turn the heat to low and allow it to cook for 7 hours.
Once the 7 hours is up, remove the oat groats from your crock-pot and either eat them right away or place them in containers in your fridge.
Re-heating instructions:
Spoon out the amount of oat groats you would like to eat into a microwave safe bowl. Break up the large clumps just a bit with your spoon. Add a few tablespoons of water or almond milk to the bowl and then microwave for about a minute. Break up the rest of the clumps by stirring the oat groats. Add in a little more almond milk until it reaches your favorite oatmeal consistency. Add in toppings and enjoy!
*The oat groats in the pictures were made with 6½ cups of water. The more water you add, the softer and "mushier" the oat groats will be. I have done as much as 8 cups before. The oat groats were pretty mushy and soft when I used the 8 cups. Add the amount of water based on how soft you would like your oat groats to be.
