  • Total Time: 6–8 hours
  • Yield: 8 servings

Ingredients

  • 1 tablespoon butter (to grease the slow cooker)
  • 2 cups steel-cut oats
  • 7 cups water
  • 4 medium apples, cored and diced
  • ¼ cup brown sugar or maple syrup
  • 1 teaspoon ground cinnamon
  • ½ teaspoon salt
  • 1 cup milk (any kind)

Instructions

  1. Grease the inside of the slow cooker with butter to prevent sticking.
  2. Add steel-cut oats, water, diced apples, brown sugar or maple syrup, cinnamon, and salt. Stir to combine.
  3. Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours.
  4. Stir in the milk until well combined. Add more milk if a thinner consistency is desired.
  5. Serve warm with optional toppings like extra apple slices, maple syrup, chopped nuts, or yogurt.

Notes

  • Use certified gluten-free oats to make it gluten-free.
  • Substitute almond or oat milk and use coconut oil or non-stick spray for a dairy-free version.
  • Apple pie spice can be used instead of cinnamon for extra flavor.
  • Add raisins or nuts during the last 30 minutes of cooking for more texture.
  • Store leftovers in the fridge for up to 5 days or freeze for up to 3 months.
