The slow cooker is a great vessel for making oatmeal for brunch, meal prep, or feeding a crowd. I load up the oats with lots of fruit and a little maple syrup to sweeten them and top them with chopped nuts. I tested this recipe with quick- cooking steel cut oats, which I loved in these savory oats. You can also make Instant Pot Steel Cut Oats. This can easily be made gluten-free.

Slow Cooker Steel Cut Oats

This healthy breakfast is not only high in fiber, but it’s also delicious. Steel cut oats are processed less than old fashioned and quick-cooking oats, so they have the most fiber and protein. Plus, one of my favorite ways to boost the protein content is to add egg whites – you can’t taste them, and they don’t change the texture. Win, win! If you want to omit the egg whites, that’s perfectly fine too.

Slow Cooker Steel Cut Oatmeal Ingredients

  • Oats: I used Bob’s Red Mill Quick-Cooking Steel Cut Oats. If you use regular steel cut oats, you’ll need to cook them longer. Check labels for gluten-free.
  • Liquids: I use two cups of water for every cup of oats, almond milk would also work.
  • Maple Syrup for sweetener.
  • Cinnamon for flavor.
  • Egg Whites for extra protein. If you’re allergic you can omit.
  • Banana: Slice one ripe banana.
  • Berries: Two cups of fresh berries, like blueberries, blackberries, and raspberries
  • Nuts: Pecans, almonds or walnuts will work.

Do steel cut oats take a long time to cook?

Steel cut oats take longer to cook than other types of oats. However, quick- cooking steel cut are faster than regular steel cut ones. The slow cooker is the perfect way to make them because you can set it and forget it for a couple of hours.

How do you cook oats in a slow cooker?

  1. Put the oats, water, maple syrup, and cinnamon in the crock pot, and then add the fruit.
  2. Cover the slow cooker and cook on low for two hours.
  3. Top the oatmeal with the chopped nuts and more syrup if desired.

How long does cooked oatmeal last in the fridge?

Slow cooker oatmeal is perfect for meal prep. It will keep in the refrigerator in an airtight container for up to six days. To reheat it, add a splash of milk or water, and heat it in the microwave or on the stove until warm.


  • Make It Vegan: Omit the egg whites to make it vegan.
  • Berries: I used a mix of berries, but you can stick to one, like all blueberries or strawberries, if you wish.
  • Fruit: Substitute raisins or apples for any of the fruit.
  • Vanilla or Cinnamon: Add some vanilla extract or cinnamon sticks before cooking.
  • Sweetener: Swap maple syrup for honey.
  • Toppings: Top your oatmeal with fresh berries, sliced bananas, a drizzle of peanut butter, coconut flakes, or a spoonful of chia seeds. You can also top it with a dollop of yogurt for more protein.
  • Chocolate: Swap out the berries for chocolate chips.
