Pro Tips

  1. Spray your slow cooker! A little cooking spray will save you from scrubbing stuck-on oatmeal later.
  2. Use a timer if your slow cooker has one. Steel-cut oats cook in about 7–8 hours, so you can time it perfectly for when you wake up.
  3. Double the batch! Leftovers reheat beautifully for easy breakfasts all week.
  4. Stir before serving. It’ll look separated when it’s done, but a quick stir makes it creamy and smooth.
  5. Make it your own. Let the kids choose toppings to make their bowls extra fun and personalized.

Tools You’ll Need

  • Slow cooker
  • Measuring cups and spoons
  • Cooking spray
  • Wooden spoon or spatula for stirring

Substitutions and Variations

  • Milk: Use any milk you like—almond, oat, soy, or regular dairy milk. Or skip it entirely and use all water.
  • Sweetener: Swap brown sugar for maple syrup, honey, or a sugar-free alternative.
  • Spices: Add nutmeg, cardamom, or pumpkin spice for a flavor twist.
  • Add-ins: Stir in raisins, chopped apples, or shredded carrots before cooking for extra flavor and texture.

Make-Ahead Tips

  • Prep all the ingredients in your slow cooker the night before, then just turn it on before bed.
  • Store leftovers in an airtight container for up to 5 days. Reheat with a splash of milk or water to loosen it up.
