Ingredients
  

  • For the steel cut oats:
  • 1 cup steel cut oats
  • 2 cups water
  • 2 cups unsweetened almond milk or any plant milk
  • 1 cup mashed banana from one small banana or ½ cup applesauce
  • Pinch salt
  • Optional toppings:
  • 1 cup seasonal fruit chopped
  • Nuts or nut butters almond butter, peanut butter
  • Maple syrup cinnamon, chia seeds, toasted coconut, or seeds
  • Bold note: This recipe stays fully vegan — no dairy no sneaky butter. Just wholesome oats and plant-based milk.

Equipment

  • 6–7 quart slow cooker / Crockpot (my notes use a 6½-quart model)
  • Heat-resistant bowl or small casserole dish that fits inside the slow cooker (for water bath method) or four mason jars (¼ cup oats + 1 cup liquid per jar)
  • Measuring cups & spoons
  • Mixing spoon and spatula
  • Optional: slow cooker liner or cooking spray for direct method
  • Want no-fuss cleanup? Use a slow cooker liner or mason jars. IMO, jars feel special and store beautifully.

Method
 

  1. A — Water bath method (my preferred foolproof way)
  2. Mix steel cut oats, water, almond milk, mashed banana (or applesauce), and pinch of salt in a heat-resistant bowl or small casserole dish. Stir well.
  3. Place the bowl (or mason jars) into the slow cooker. Fill the slow cooker halfway with hot water so the dish sits in a water bath.
  4. Cover and cook on low for 4 hours for creamy oats. For thicker oats, cook up to 5 hours on low.
  5. Serve: Divide into 4 bowls and decorate with fruit, nuts, or nut butter. If you used jars, serve them right in the jars.
  6. B — Direct slow cooker method (no water bath)
  7. Spray the slow cooker bowl with cooking spray or line with a slow cooker liner.
  8. Combine oats, water, plant milk, mashed banana, and salt directly in the slow cooker. Stir.
  9. Cook on low for 4–5 hours, checking at 4 hours for creaminess.
  10. Stir before serving and add toppings.
  11. Pro tip: If you cook overnight, switch the slow cooker to warm after 4 hours to keep the texture perfect until breakfast.
