Notes

  • If you prefer creamier oatmeal, use milk or nondairy milk of your choice instead of water, except for in the overnight method (for safety, dairy milk shouldn't be left at room temperature overnight). I recommend nondairy milk for the Instant Pot or slow cooker to prevent curdling.
  • For a nutty, more flavorful taste, toast the oats before cooking.
  • Add a pinch of salt before cooking if you prefer.
  • Make sure you are using regular steel cut oats for these recipes, not the quick cooking kind. The quick cook kind don't take near as long.
  • Use steel cut oatmeal as a blank canvas for all kinds of breakfast bowl creations! Top with fruit, nuts, spices, nut butter, seeds, or really anything your heart desires.
  • Store leftover steel cut oatmeal in an airtight container in the refrigerator or freezer.
  • To make individual freezer portions, pour cooked oatmeal into large silicone ice cube trays or silicone muffin liners. Freeze. Once frozen, pop out the portions and store them in a freezer bag.
  • To reheat in the microwave, place in a microwave-safe container and heat 1-2 minutes, or until hot. Add milk of choice and stir.
  • To reheat on the stove, add 2-4 tbsp water or milk per serving and cook over medium-low heat, stirring, until warm.
