Looking for a hearty, stick-to-your-ribs kind of breakfast that you don't have to work hard for on busy mornings? We get it. That's why we love making overnight slow-cooker oatmeal. Our crockpot oatmeal recipes are hearty and warming, and they're easy to put together the night before so you can wake up in the morning to a tasty, filling, nutritious breakfast. 

Quick Tip

When cooking oatmeal in the slow cooker, use steel-cut oats instead of quick oats. Quick oats will not hold up well over the extended cooking time, while steel-cut oats will maintain a much better (less mushy) texture.

Basic Slow Cooker Oatmeal Recipe

Plain oatmeal

This one is plain, but you can totally stir anything you want into it. Cinnamon, blueberries, raisins, a little honey — the world is your oyster... or your oatmeal. 

Makes 6 to 8 servings

Ingredients

  • 1 tablespoon unsalted butter
  • 8 cups water
  • 2 cups milk or almond milk
  • 2 cups steel-cut oats
  • ¼ teaspoon salt

Instructions

  1. Lightly grease the slow cooker insert with the butter, coating it thinly to keep the oatmeal from sticking.
  2. Measure all ingredients in the slow cooker and stir to combine.
  3. Cover the slow cooker and turn it on to low. Allow it to cook for eight hours.

Maple Brown Sugar Slow Cooker Oatmeal

Instructions

  2. Add the water, milk, oats, salt, syrup, and brown sugar and stir to combine.
  3. Cover and turn the slow cooker on to low. Allow it to cook for eight hours.
  4. Just before serving, stir in the pecans, if using.
