For days where you wish breakfast had made itself, the slow cooker comes to the rescue with these creamy, delicious, steel-cut oats.

Crockpot oatmeal might be one of the easiest recipes to make with basic pantry staples for a warm and cozy breakfast that’s good for you.
Something important to note right now is that crockpot oatmeal works best with steel-cut oats -I’ll tell you more about this further down.
How to Make Oatmeal in the Crockpot
Crockpot oatmeal is as simple as combining oats and milk in the slow cooker, set it to cook overnight.
You read that right, the slow cooker has the power to turn oats into creamy, oatmeal perfection. The oat base can be adapted to your liking with unlimited variations.
For this recipe, we’re adding diced apples and cinnamon into the mix where the apples will cook slowly overnight and, in the morning, you have the most epic apple pie tasting breakfast.
For these reasons, it’s pretty much always on repeat in my house, and after you try this apples and cinnamon version, it’s sure to be a staple recipe in yours too.
As stated above, this recipe is adaptable, so you can swap the apple for another favorite fruit like berries or wait to add them until the oatmeal is cooked and ready to be served.
Here’s everything you’ll need to make this perfect apple and cinnamon-spiced oatmeal happen:
- steel-cut oats (a must!)
- milk of choice
- vanilla extract
- cinnamon
- diced apples

Best Oats for Crockpot Oatmeal
Steel-cut oats are essential for making slow cooker oatmeal. They can withstand the long cooking time and retain their texture. Using anything other than steel-cut oats will result in a creamy mush, not to mention that quick or instant will practically dissolve.
Using old-fashioned oats will result in a creamy porridge almost like a puree. The oats will also lose their texture -sadly.
