Slow cooker oatmeal is a simple, nourishing breakfast that feels a little special but asks almost nothing of you in the morning. Just toss everything into the crockpot before bed and wake up to warm, cozy oatmeal that's hearty, creamy, and kissed with warming spices and rich maple.
This recipe tastes like the classic maple brown sugar oatmeal packets and is just as easy, if not easier, to make. The difference? Crockpot oatmeal has a creamier texture, less sugar, and simple ingredients that help keep you full all morning.

Kristen's Keys for Crockpot Oatmeal
A few small details make a big difference with slow cooker oatmeal. Paying attention now will help you get perfectly creamy oats. No scorching, no watery oats, and always perfectly flavored.
- Use steel-cut oats only. Rolled or quick oats will overcook and turn mushy during long, overnight cooking. Steel-cut oats hold their shape and give you a hearty, chewy, satisfying texture.
- A combination of milk and water yields the best results. The water keeps the milk from scorching on the bottom of the slow cooker, while the milk (regular or non-dairy) gives the oats a creamy consistency.
- Grease the slow cooker well. This helps prevent sticking and makes cleanup much easier in the morning.
- Low and slow is best. Cooking on low for 6-8 hours gives the oats time to soften evenly without breaking down--and let's you get a good night's sleep.
5-star Reader Review
This recipe is in regular rotation at our house. It's creamy, flavorful, and so easy! I love putting it together Friday or Saturday night for a healthy and comforting breakfast with the family in the morning and then having leftovers to enjoy throughout the week. I follow the recipe as written and it has never failed me! My slow cooker has limited settings, so I can only do 8 hours on low and it always works out great for me. -Heather C.
How to Make Slow Cooker Oatmeal
While it is incredibly easy to make oatmeal in the crockpot, this section walks you through the steps, providing tips along the way.
Step One: Grease the Insert
Generously brush the insert of your slow cooker with coconut oil or canola oil, ensuring the sides and bottom are well coated. Alternatively, you can use butter or cooking spray, but I find using canola or coconut oil results in the easiest clean-up.
Step Two: Combine Ingredients
Combine the steel-cut oats, water, milk, maple syrup, brown sugar, cinnamon, vanilla, and salt together in the slow cooker. Yes, it is really THIS easy!

Step Three: Slow Cook Oats
Cover and cook on low heat for 6-8 hours. A cook time of 6 hours results in firm, slightly chewy oatmeal; while 8 hours results in creamier, softer oatmeal. Both delicious.
👉🏻Short on time? You can cook the oatmeal on HIGH for 3-4 hours, but overnight on low gives the best texture and less risk of burning the oatmeal.

Step Four: Serve
In the morning, give the oatmeal a stir and serve warm with a drizzle of additional maple syrup and sprinkle of chopped nuts if desired.

Recipe Modifications
- Gluten-Free: Be sure your oats are certified gluten-free.
- Dairy-Free & Vegan-Friendly: Use almond milk, coconut milk, or another variety of non-dairy milk and brush the slow cooker insert with either coconut oil or canola oil.
- Lower Sugar: Reduce the brown sugar by up to half and let the maple syrup carry the flavor.
- Extra Protein: Stir in yogurt or protein powder after cooking so the oatmeal stays smooth and creamy.
- Additional Fiber: Add up to ¼ cup of either ground flaxseed or wheat germ before cooking for a nutrition boost without changing the flavor.
- Change the Texture: For thinner oatmeal, use 8 cups of liquid; for thicker oatmeal, use 6 cups of liquid.
- Flavor Ideas: Add frozen berries before slow cooking or finish with sliced bananas of fresh berries. Swirl in peanut butter and chocolate chips or candied walnuts before serving or try out my recipe for Strawberries and Cream Oatmeal.
- Use a Liner: You absolutely can use a slow cooker liner if desired for easier clean-up. I don't find that necessary when well greased, but it won't change anything if you decide to go for that option.
Storage Tips
While I designed this recipe to cook overnight in your slow cooker, you can also opt to prepare it during the day, let cool, and reheat for an effortless breakfast on busy weekdays.
- Refrigerate: Store leftover oatmeal in an airtight container in the fridge for up to 5 days. Reheat individual servings in the microwave for 1-2 minutes, adding a splash of milk to thin as needed.
- Freeze: Let the oatmeal cool completely, then transfer to freezer-safe containers (individual portions work best). Freeze for up to 3 months. Thaw overnight in the fridge, then reheat in a microwave-safe bowl in 30-second intervals, stirring between each, until warmed through. Add milk as needed to loosen it up.

Can I add apples to the recipe and do I add at the beginning of the cooking time
If you would like your apples to be soft, yes! Dice up peeled apples and mix into the oats.
Probably the best oatmeal I have ever had!! So easy to assemble!! The flavors were perfect, just enough sweetness! Perfect for a cold morning!
YAY! So glad you enjoyed Dana! It does make breakfast that much easier.
What size crockpot did you use? Would it be ok to halve the recipe for a smaller crockpot? I’m excited to try this
I have a 6-quart crockpot. You can half the recipe for a smaller crockpot. Enjoy!
I have been looking forward to trying this different overnight oatmeal recipe. I found gluten free steel cut oats (Bob’s Red Mill). The only difference I made was not to add maple syrup while cooking but offering it when it was served. Right before serving I added 1/2 stick butter. We are just a butter family! Lots of different toppings can be offered at serving, milk, cream, berries or nuts. Thank you for such a great way to wake up to a warm breakfast and a house smelling delicious!!
So glad to hear you enjoyed.
I am planning to make this using the slow cooker feature of my instant pot but would like to cut the recipe in half ( it's just my husband and I). Are there any changes I need to make other than halving the ingredients?
Hi LuAnn! I would follow my guidelines for using your Instant Pot as a slow cooker to adjust the timing.
If I understand correctly, this recipe makes 8 - 1.25 cup servings. Is that right?
This sounds like the perfect breakfast for Christmas morning.
Yes that is correct Lisa! I hope you enjoy!
What size slow cooker for this recipe? Or did I miss that somewhere? Also, have you ever added raisin?
Hi Carole, I use a 6 quart instant pot. And raisins are delicious. Add while cooking if you want them to plump up or add after cooking if you want them to retain their texture.
Made this last night before bed, and woke up to a delicious hot breakfast! So yummy!!! I have told about 20 people about it so far. Would be great for visiting family over the holidays or for overnight guests.
I am so glad you enjoyed Joan! This would be delicious for entertaining as well.
Can I add peanut butter to this for extra protein?
I would stir in the peanut butter after it cooks Rachel--it will melt right in the oatmeal.
