    The backstory.

    I started making these slow cooker steel cut oats during one especially busy season when mornings felt extra rushed. Between getting everyone out the door and trying to remember if I'd already reheated my coffee three times, having breakfast ready to go was a lifesaver. Now this crockpot breakfast has become one of those cozy little routines we come back to whenever we want something warm, easy, and filling without much effort.

    It's a must make.

    There's something extra comforting about waking up to slow cooker steel cut oats blueberry bubbling away in the kitchen while the coffee brews and the house slowly wakes up.

    • It makes mornings easier. Everything cooks overnight so breakfast is ready when you are - no extra morning chaos required.
    • It's warm and cozy. The cinnamon, brown sugar, butter, and blueberries make every bite taste like comfort food in oatmeal form.
    • It's hearty enough to keep everyone full. Steel cut oats have that satisfying texture that sticks with you way longer than sugary cereal.
    • It's easy to customize. Fresh berries, dried fruit, different nuts, maple syrup - this recipe plays nice with whatever you've got hanging around the pantry.

    Let's talk flavor and texture.

    These blueberry oats are creamy, rich, and perfectly comforting without feeling heavy. The steel cut oats keep a slightly nutty texture while soaking up all that buttery cinnamon goodness. Fresh blueberries soften just enough to burst into the oatmeal, adding little pockets of sweet-tart flavor in every spoonful. Add a splash of cream on top and it turns into the kind of breakfast you'll want to curl up with under a blanket while pretending your to-do list doesn't exist for five minutes.

    What you'll need.

    Slow cooker blueberry oatmeal keeps things simple with wholesome pantry staples and cozy add-ins that make your kitchen smell amazing by morning.

    • Steel cut oats: The star of the show. They hold their texture beautifully during slow cooking and create that creamy-yet-hearty bite.
    • Water: Helps the oats slowly soften and cook overnight.
    • Salt: A little salt wakes up all the flavors and keeps the oatmeal from tasting flat.
    • Cinnamon: Adds warmth and that classic cozy breakfast flavor.
    • Butter: Makes the oats extra rich and comforting.
    • Brown sugar: Sweetens everything with a soft caramel-like flavor.
    • Vanilla extract: Brings warmth and rounds out the sweetness.
    • Chopped walnuts: Add crunch and a nutty finish. Slivered almonds work great too.
    • Fresh blueberries: Sweet, juicy, and perfect for blueberry oatmeal.
    • Half and half or creamy oat milk: Makes the oats silky and creamy.
    • Dried cranberries: Optional, but they add chewy sweetness and extra flavor.
    • Optional toppings: Brown sugar, butter, cream, extra blueberries, and nuts make every bowl even better.

    How to slow cooker oatmeal with blueberries.

    Slow cooker steel cut oats blueberry is mostly hands-off, which is exactly the kind of breakfast energy I'm looking for.

    1. Add the oats, water, and salt to your greased crock pot and give everything a quick stir.
    2. Cover and cook on low until the oats are tender and creamy. Depending on your slow cooker, this can take anywhere from 4 to 8 hours.
    3. Once the oats are cooked, stir in the butter, brown sugar, vanilla, cinnamon, and walnuts until everything melts together.
    4. Gently fold in the blueberries and let the oatmeal sit for about 10 minutes before serving warm with your favorite toppings.

    Make it your way.

    One of the best things about slow cooker oatmeal with blueberries is how easy it is to switch things up depending on what your family loves.

    • Swap the blueberries for chopped bananas, raspberries, strawberries, or blackberries.
    • Stir in shredded coconut with the berries for extra texture and sweetness.
    • Use maple syrup instead of brown sugar for a cozy maple flavor.
    • Try pecans or sliced almonds in place of walnuts.
    • Add a spoonful of chia seeds or flaxseed for extra fiber.
    • Use creamy oat milk to keep things dairy-free.
    • Use rolled oats instead of steel-cut oats.
    • Stir in a little nut butter before serving for extra richness and protein.

    Busy mornings are a whole lot easier when breakfast is already waiting for you. That's why we love cozy recipes like Overnight Apple Cinnamon Crockpot Oatmeal and Overnight Crockpot Banana Oatmeal. Just toss everything in the slow cooker the night before and wake up to a warm, comforting breakfast that makes the morning rush feel a little less chaotic.

    How to serve it.

    Slow cooker steel cut oats blueberry is best served warm with plenty of cozy toppings piled on top.

    • Add an extra pat of butter and a drizzle of cream right before serving for ultimate comfort-food vibes.
    • Sprinkle on extra walnuts or almonds for crunch.
    • Pair it with crispy bacon or sausage for a balanced breakfast.
    • Serve with fresh fruit and yogurt for an easy brunch spread.
    • Spoon leftovers into containers for grab-and-go breakfasts during the week.

    Kori's tips.

    • Know your crockpot before cooking overnight - some slow cookers run much hotter than others and can cook the oats way faster.
    • Grease the crockpot well so the oats don't stick around the edges.
    • Sweeten to your taste. I keep this recipe moderately sweet so everyone can adjust their own bowl.
    • Don't stir the blueberries too aggressively or they'll completely break apart into the oatmeal.
    • If the oatmeal thickens too much after sitting, stir in a splash of milk before serving.

    FAQ's

    What is the best way to store it?

    Allow the oats to cool, then transfer them to an airtight container and store them in the fridge for up to 5 days.

    How do I reheat it?

    Transfer a portion to a microwave safe dish and cover. Heat in 30-40-second increments until your desired temperature is met.

    Can I freeze it?

    Yes! Let the oatmeal cool completely, then portion into freezer-safe containers. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.

    Do you add milk or water to steel cut oats?

    You can do either milk or water. If cooking them in a slow cooker, I use water, then add cream or milk before serving them to make them extra creamy.

    Ingredients
      

    • 2 cups steel cut oats

    • 6 tablespoons butter
    • ½ cup brown sugar
    • 2 teaspoons vanilla extract
    • ½ cup chopped walnuts (slivered almonds may be used)
    • 1½ cups fresh blueberries
    • ¾ cup half and half or creamy oat milk

      Adding the steel cut oats to a white oval crockpot.

    Notes

    • Don't miss all of our helpful hints, substitution ideas, cooking tips, and other delicious recipes that can be found in our post. Check it out!
    • TOP TIPS:
      • Sweeten the oats to your taste preference; I used a moderate amount of sweetener so you could adjust the sweetness to your liking.
      • Slow cookers can vary drastically in temperature. Know your crockpot before turning these on and cooking overnight. I made these in two crockpots (both were set on LOW) - one had the oats done and boiling in 4 hours - and the other took 7 hours. 
    • VARIATIONS: Make these oats with any of your favorite ingredients - any combination of fresh or dried berries is lovely; chopped almonds or pecans can be used instead of walnuts; coconut can be added with the blueberries; fresh banana can be used instead of blueberries; maple syrup makes a delicious sweetener instead of brown sugar. 
    • SERVING SUGGESTIONS: Serve with a dollop of butter, cream, brown sugar, and additional berries and nuts.
