FAQ

  • Can I use rolled oats instead of steel-cut oats?

    While you can, steel-cut oats are recommended for slow cooking as they hold their shape better and don't become mushy. Rolled oats may become too soft and lose their texture.
  • Can I use a non-dairy milk?

    Yes, you can use any type of milk you prefer, such as almond milk, soy milk, or oat milk. The cooking time will remain the same.
  • How do I prevent the oatmeal from sticking to the slow cooker?

    Greasing the slow cooker well with cooking spray helps prevent sticking. You can also try using a slow cooker liner for easy cleanup.
  • Can I add protein powder to the oatmeal?

    Yes, you can add protein powder to the oatmeal after it's cooked. Stir it in thoroughly and adjust the liquid if needed to maintain the desired consistency.
  • Can I make this recipe vegan?

    Yes, to make this recipe vegan simply use a plant-based milk alternative, like almond, soy, or oat milk. Ensure any toppings you add are also vegan-friendly.
