Make meal-prep a breeze with this easy Slow Cooker Steel Cut Oatmeal recipe. It's a hearty, fiber-packed breakfast that will keep you full until lunchtime!
Gather all of the ingredients together. Grease the bottom and sides of a 4-6 quart slow cooker with butter.**
Add the steel cut oats, water, milk, salt, cinnamon, vanilla, and brown sugar to the slow cooker. Stir everything together until combined and sugar is dissolved.
Cover and cook on high for 2.5 to 3 hours or on low for 5 to 6 hours. Stir the oatmeal halfway through and quickly return the top to finish cooking. Serve immediately with maple syrup and your favorite toppings***.
*Steel cut oats require a lot more liquid than regular old-fashioned oats to cook. I used a combination of water and milk to give the oatmeal a creamy texture. For this reason, I don't recommend swapping the steel cut oats for any other kind of oat in this recipe. Quick-cook or old-fashioned (rolled) oats are much softer and can become mushy in the crockpot.**It's important to grease your crockpot well. Otherwise, the steel cut oats can stick during cooking.***Top with any of your favorite toppings! I love maple syrup and an extra sprinkle of cinnamon, but diced apples and chopped walnuts are a close second. Some other topping ideas include bananas, berries (fresh or frozen and thawed), strawberry jam, pumpkin butter, slivered almonds, dried cherries or cranberries, granola, or sunflower seeds.
