Slow Cooker Steel Cut Oats made with quick steel cut oats, berries, bananas, maple syrup, and nuts are an easy, high-fiber breakfast!

Slow Cooker Steel Cut Oats
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.
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?
- Put the oats, water, maple syrup, and cinnamon in the crock pot, and then add the fruit.
- Cover the slow cooker and cook on low for two hours.
- 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.
Variations:
- 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.

Over the years, I have tried other oats receipes for breakfast and was very disappointed. This recipe is OUTSTANDING! I didn’t use the slow cooker method and it was so very good!!
Thank you for this recipe, Gina. I love organic steel-cut oatmeal and it’s a staple in my daily breakfast. I haven’t tried it in the slow cooker yet but now I have a reason to bring it out and get cooking. Also to note, “oats” is misspelled as “outs” in the Notes section (see “…for regular steel cut outs…”). Thank you again, and I have the Skinnytaste Simple cookbook—such a great gift. I appreciate you.
Delicious! I didn’t have any egg whites, so I made it without them. But I followed the recipe exactly, otherwise, and it turned out great.
This is so easy for prepping a week’s worth of oatmeal!! So easy
An excellent recipe. I make it every few days and fill up little containers to enjoy every morning. Best was with fresh blueberries. Frozen berries work too but seem to discolour the oatmeal and need a longer cooking time. Keeps me very full even when I omit the banana and nuts. Thanks Skinnytaste for another keeper.
Glad you enjoy it!
My daughters (4 & 6) day this is their new favorite breakfast! I had to use 2.5c water and stir at the hour mark using the crock pot. Amazing!
Delicious
For fruit I used blueberries, raspberries and blackberries.
Will make it again.
Do you need to use the banana or is it just an additional fruit like the berries?
I really despise banana.
no, banana is not required. It would make oats taste sweeter, but not necessary.
I thought this was delicious. Used banana, dried fruit, pecans, date syrup because I needed to use it up and regular steel cut oats because that’s what I had on hand. Next time I will add the egg white. I was a little hesitant for some reason. My crockpot may run hot but it was done in a little over 2 hours.
Is it possible to sub milk for the water to give even more protein? Or would the milk not cook well in the crockpot?
Milk will make it stick and burn onto the crock like concrete I cook it with water and serve it with warmed Milk
Nobody does it better! You lighten up recipes that always come out great. I’ve tried several of your recipes over the past few years. Thank you!! I haven’t tried this one yet, but it looks wonderful! I like that you added egg white for protein. I’ve been looking for a baked oatmeal recipe, but will try this too. Thanks!
Nice to use quick cooking type steel cut oats. Works like a charm. Love the egg whites in all my oatmeals, makes them fluffier and helps volume too I think. Have done this one several times. I often wait to add berries till the end, as I find they cook up too much in my slow cooker. A favorite
Any advice on using a instant instead?
Check out this one- https://www.skinnytaste.com/instant-pot-steel-cut-oats/ 🙂
An easy, quick way to dress up a healthy breakfast! I used the stovetop method for a quick weekday breakfast. Delicious, easy, and filling.
Not a fan I found it quite dry. The baked oatmeal with coconut, blueberries and banana recipe in the Fast and Slow cookbook is what I would recommend.
I have tried sooo many oatmeal recipes but this is the only one I LOVE! So good.
Yay!!!!
Oh, my goodness! This recipe is sooo good! Will be making it often!
This is so good. It has become a staple in my house.
I prepared this recipe for breakfast and the texture of the steel oats was perfect. The addition of berries and banana was the perfect combination. Another hit from Gina!
Thanks Claudia!
It’s an easy way to get plenty of protein, fruits, and fiber in a delicious breakfast! Thanks for another great recipe!
What do I need to change if I only have quick oats to use?
Annette, that’s like making a mimosa with Orange Crush, it’ll be something, just not what Gina has created here.
This analogy is the best! I fully agree. Only steel cut can be cooked in this method. If you replace with quick oats the texture will become mushy and more like a cream of wheat situation.
Looks good, can you use frozen mixed berries?
I use 1 cup of almond milk instead of water to get the protein (no eggs). Then use old fashioned oats. Add bananas closer to the end. Slower cooker duration 90 minutes
I just bought a large container of regular (not steel cut) oats but would love to try this out! Can this be done with some adjustments? TIA!
Yes, I am assuming it could with more time?
Is the blue 6 for WW blue plan?
Thanks.
What size slow cooker are you using? Mine is 6 quarts, which seems way too big for this recipe.
This recipe was delicious! I cooked it both ways, and both turned out great. Crockpot easier because you can just leave it and not keep stirring, but stovetop was faster of course.
Just made this. I don’t really like oatmeal but a few years ago I made an overnight steel cut oatmeal apple and cinnamon and liked it so much better than rolled oats. This recipe is so good and only took a few hours. I used a crock pot liner for easy clean up
When did you put in the Apple? The whole time or at the end?
This is a seriously delicious recipe! I made it this afternoon so that I would have breakfasts at the ready over the next few days. It was so simple to assemble in the slow cooker and just set it on low for a couple of hours. The small bowlful that I tried when it finished cooking turned into two small bowlfuls! Delicious! It will be so warm and comforting on the chilly mornings ahead. Thanks, Gina, for another five star recipe!
Sounds great, I’ll have to give this a try! But with regular steel cut oats – the quick ones have a weird gummy texture that I don’t care for.
Haven’t tried yet, but I will in the morning. Your recipes never disappoint.
Thank you!!
Can a frozen berry medley be used?
Sure
Can this be made without the egg? Should flax or chia seeds be added if egg is omitted?
You can just omit or add chia for protein if you wish
Looks delicious! Are the oats used in this recipe gluten free? If not, will ones that say gluten free on the packaging work too?
gluten free steel cut oats will work, if they are not quick steel cut oats they need 4 hours
While oats are naturally gluten free, they may come in contact with gluten-containing grains such as wheat, rye and barley at the farm, in storage or during transportation.
