Steel-cut oats cook overnight with bananas, walnuts, and spices to create a healthy, make-ahead breakfast that will be waiting for you in the morning.

If I had to offer one secret when it comes to reaching weight loss or healthy living goals it would be to start every day with a healthy breakfast. Of course, you’ve heard it 100 times but I also know that it isn’t so easy for everyone. People often tell me they don’t have time to make breakfast or they aren’t hungry first thing in the morning.

Listen up, friends. You must make eating breakfast a part of your daily routine. If you aren’t hungry in the morning, that likely means your metabolism isn’t running at it’s highest potential. Even if you just start with a piece of fruit or a slice of whole-grain toast, try to eat something within an hour of waking up.

Breakfast literally means “breaking the fast”. You haven’t eaten in close to 12 hours and your body needs a balanced meal to get going again! If you start eating breakfast, your body will begin to crave it when you wake up. Hunger is a sign of your metabolism functioning and the higher the metabolism, the more calories you burn throughout the day – even when you’re sitting on your bum playing on Pinterest.

And for those of you who claim not to have time in the morning, I’ve taken that excuse out of the pile! Take five minutes the night before to throw together this slow cooker banana nut oatmeal and you will wake up to delicious aromas of bananas, walnuts and spices. Since the slow cooker will keep it warm, everyone can help themselves in the morning regardless of their schedule. Easy as pie…er…oats.
Your spoon is waiting.

Thank you for the recipe. I made it this morning for my kids. It was nice to just throw everything in and then get ready for work. I hope to try more recipes like this one.
OH PERFECT!!! How did they like it?
This looks like such a delicious, yet healthy breakfast. We enjoy oatmeal, but don’t often have time to make it in the mornings. I love that it is cooked in a slow cooker.
Yes so easy!
In the morning everything is ready to go. Well, everything except for a fresh fruit garnish. This banana nut steel-cut oatmeal is a great option to start.
So glad you like it!
This sounds delicious! I LOVE oatmeal and can’t wait to try it. I really like to make a crockpot egg casserole…
I hope you love it!
This is by far the coziest breakfast!!
So easy too!
Never thought breakfast means ‘breaking the fast’. That got me smiling. I love bananas and will use almond milk. Yum! Thanks for sharing.
hahah :) Enjoy!
Oh my! This banana nut oatmeal was delicious and so easy to make! Will have to try this for my family. Thanks so much!
I’m so happy you loved it!!!
Really wanted this to work. I used the. Vitaclay slow cooker so took less time (2 hours). However a lot stuck to bottom and was burned. The cinnamon taste was overwhelming. Really wanted to like this. But unfortunately the taste wasn’t good. There was also an element of burned taste due to the bottom part burning.
Hi Sumera, I’m so sorry to hear this didn’t work for you! I’ve never used one of those slow cookers but I have heard some people having success placing the oats in a bowl over about 2 inches of water. Either way my apologies that it didn’t work – we make this regularly and love it but we use a standard Crock pot.
Thanks for your response.
I put my oatmeal mixture in a glass bowl the fits inside the crockpot and I fill the crockpot halfway with water. It keeps it from burning and sticking.
So glad to hear!
I don’t have a glass container that I could put in the slower cooker. Should I spray the slow cooker with cooking spray?
Yes that’s a great option!
Made this just now. Tastes delicious! Added in a little extra banana and 1 tablespoon of chia seeds. I have made a lot of steel cut oats in my slow cooker and knew they would be done in just two hours on low. I let mine cool and then I portioned them out (8 servings) and I plop the portions onto a cookie sheet lined with foil and sprayed with non-stick spray. They are in the freeze now. I’ll put them in a big zip close plastic bag when they are frozen. Awesome recipe. Thanks.
Ahh love the changes you made!
I am a huge fan of all of your recipes. This one was great too. I think using almond milk didn’t get as nice a consistency, but it tasted lovely.
For all your recipes it would be really helpful to have the amount of cups or grams equivalent to one serving. It really helps with portion control and adapting recipes to Weight Watchers or similar.
Hi Gabi – I’m so glad you enjoyed it!! I apologize for the serving size. I am working to incorporate it for all my recipes in the “Notes” section. Unfortunately my recipe plugin program doesn’t support a serving size in cups so I’m trying to work around that. If there are any specific recipes you want specific amounts for just let me know.
I made this lastnight. It didn’t have much of a banana flavor, but taste more like cinnamon. The texture was weird, too. This isn’t a favorite in our house.
Hi Cait – Shoot I’m sorry this didn’t work out for you. That’s interesting – were your bananas ripe?
I only had half and half. I used one and a half cups of half and half and the other two and a half cups of water to make the four cups of liquid. Since I used half and half will this curdle?
Nope should be delicious!!
Looks like a time saver for those early mornings. I normally soak the oats with acv and rye overnight to neutralize some of the phytic acid. It also decreases the cooking time. Could I still do that with this recipe? Would I decrease the cook time?
I’m not sure Lena as I’ve never done that before – so sorry!
Hi was just wondering if anyone knew the sun value of this recipe on slimming world or if there was a way of making it slimming world friendly?
My daughter found this recipe a few months back and I made it for the first time when the kids had state testing. I wanted to make sure they had a great warm filling breakfast. They asked for it all that week and the last month have been making it at least once a week. I have never liked oatmeal but I gave this a try for breakfast and really enjoyed it. It is just as good reheated the next morning too. I use Chia seeds in a lot of things so this is what I use instead of flax.
Thank you for a wonderful recipe
Oh Stephanie I’m so happy to hear this!!! We make this all the time in the winter but you’ve inspired me to make it again soon! It’s one of our favorites!!
I’m not sure what I did wrong but when I made this, the oats themselves turned out goopy and gross-looking and the mashed banana had browned and seemed like it was burned. I had my crock pot on low for 8 hours. Only things I did differently was I used classic oats instead of steel cut because that’s all I had, and didn’t have any flax seed to include. I love the idea of this but wish it had worked better. Any advice on how to fix it? Thanks!
Hi Shannon – I’m afraid this recipe doesn’t work for old fashioned oats. You’ll need to use steel cut oats as instructed in the recipe in order to get the correct consistency. Enjoy!
I used Steel cut oats and had the same problem. The banana browned and the milk curdled.
Does your slow cooker tend to run hot? Maybe next time try more water – so sorry to hear that! We make it all the time and love it!
Same issue here. I even generously buttered my slow cooker and it still stuck to the sides and was browned and burned in a lot of places. Disappointing. I wonder if it would work if cooked for 5-6 hours instead of 8?
Shoot that’s too bad!! I will say I have four slow cookers and some are stronger than others. Try it next time for four hours. WORSE case you can always microwave a bit in the morning. Start with four and go up from there. :)
Does anyone know about soaking or slow cooking with Cream of Wheat? one of my daughters and myself prefer Bobs Red Mill Creamy Wheat/Creamy Rice farina 1/2 each. We, also, like soaking oatmeal (rest of the family) overnight and cooking to get more nutrition out of it. But, can’t see what the consistency would be for cream of wheat…just wanting to know if someone else has tried it before I possibly throw some out…:)
Oooooh cream of wheat is a great idea! Let me know what you find out!
Just discovered this recipe over the weekend…it turned out amazing! 21 Day Fixer here and it works great for me. Thank you for sharing!!
Oh I’m so glad you enjoyed it!!!! Let me know what other recipes you try Sally!
Looks great, I like my banana oatmeal with cardamom…Give it a try!
Delicious and easy once I picked out all of the burnt walnuts…I must have kept it on for too long overnight. But, my family loved it. I won’t add nuts until after cooked next time I make it!
What?? Burnt walnuts?? Oh no!! Did you add enough liquid?
