Ingredients

  • 1.5 cups steel cut oats
  • 4 cups water
  • 2 cups milk any kind you like
  • 2 large ripe bananas mashed
  • 3 tablespoons ground flaxseed meal
  • 2 teaspoons pure vanilla extract
  • 1 teaspoon ground cinnamon
  • 0.25 teaspoon freshly grated nutmeg
  • 0.25 teaspoon kosher salt

For serving

  • chopped toasted walnuts
  • raisins
  • chocolate chips
  • maple syrup
  • peanut butter

Instructions

  • Start by mashing the ripe bananas in a mixing bowl until smooth. Measure out the steel cut oats, water, milk, ground flaxseed meal, vanilla extract, ground cinnamon, freshly grated nutmeg, and kosher salt.
  • Add the steel cut oats, water, milk, mashed bananas, flaxseed meal, vanilla, cinnamon, nutmeg, and salt into your slow cooker. Stir everything together until well combined.
  • Cover and set your slow cooker to low. Cook for about 7 to 8 hours overnight. The slow, gentle heat will transform the steel cut oats into a creamy, porridge-like consistency.
  • In the morning, give the oats a good stir. If the texture is too thick for your liking, simply stir in a splash of milk or water. Serve warm topped with your favorite mix-ins like toasted walnuts, raisins, chocolate chips, or a drizzle of maple syrup.

Equipment

  • Measuring Cups and Spoons
  • Mixing Bowl
  • Wooden spoon or spatula
  • Zester or microplane
  • Serving bowls and spoons

Notes

  • Test your slow cooker timing as models vary; 7-8 hours on low gives creamy oats.
  • For dairy-free, substitute milk with almond, soy, or oat milk.
  • Store leftovers in the fridge for up to 4 days or freeze for up to 3 months.
  • Add protein powder or peanut butter after cooking for extra nutrition.
  • Sweeten naturally with extra mashed bananas or maple syrup at serving time.
