Equipment

Ingredients
  

  • 1 cup steelcut oats If you're unsure whether your rice cooker can handle this volume (boil over may occur), half this recipe for a test.
  • 3 cups water or milk
  • ¼ teaspoon salt

Optional (for Apple Cinnamon Oats):

  • 1 cup apple, peeled and chopped
  • 2 teaspoon brown sugar
  • 1 teaspoon cinnamon

Instructions
 

  • Add Ingredients: In your rice cooker pot, combine steel-cut oats, water (or your choice of liquid), chopped apples, cinnamon, and a pinch of salt.
  • Select Cooking Mode:
    If using a multi-function rice cooker (like a Cuckoo), select the Porridge setting.
    If using a standard one-function rice cooker (like a Tayama), simply press the Cook button.
  • Let It Cook: The oats will cook automatically. Once finished, your rice cooker will either switch to the Keep Warm setting or shut off, depending on your model.
  • Stir: Once done cooking, stir in the bit of excess liquid into the oats.
  • Serve & Enjoy: Serve immediately  or let it stay on the Keep Warm setting overnight and enjoy it in the morning.

Notes

Nutritional facts provided are estimates and may not be entirely accurate.

Approximate Cook Times:

  • Cuckoo Rice Cooker (Porridge setting): ~53 minutes
  • Tayama Single-Function Rice Cooker: ~16 minutes
    Note: Cooking times may vary slightly depending on the model and batch size.

Boil over problem: 

  • Some rice cookers, especially those with less advanced temperature regulation, may not be able to handle the high boiling of oats and liquid, causing a spillover.
  • If you’re unsure about the rice cooker's capacity, start by using ½ cup of oats and test the recipe.
  • Or reduce pressure buildup by increasing ventilation:
     Place a long wooden spoon or chopsticks between the pot and the lid. This allows steam to escape, reducing the chance of a boil-over.
