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. 
Slow Cooker Banana Nut Oatmeal - The Lemon BowlIf 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.

Crock Pot Banana Nut Oatmeal - The Lemon BowlBreakfast 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.

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.
Recipe type: Breakfast
Serves: 4
  • 1 cup steel cut oats
  • 1 ripe banana - mashed
  • ¼ cup chopped walnuts
  • 2 cups skim milk (or almond milk)
  • 2 cups water
  • 2 tablespoons flax seed meal
  • 2 teaspoons cinnamon
  • 1 teaspoon vanilla
  • ½ teaspoon nutmeg
  • ½ teaspoon salt
  • banana slices, walnuts or brown sugar - optional garnish
  1. Place all ingredients in slow cooker and stir until well combined.
  2. Cook overnight on Low for 8 hours.
  3. In the morning, stir oatmeal with a fork to loosen the steel cut oats and make sure everything is fully incorporated.
  4. Serve warm with banana slices, chopped walnuts or a pinch of brown sugar if you wish.
For easier clean-up and to avoid the slight "crusty" residue inside the slow cooker, place all ingredients in a glass bowl that fits into the slow cooker then add enough water to fill the lower half of the slow cooker. Cover and cook on low for 6 to 8 hours.

    This looks fabulous, Liz… I can’t wait to give it a try! I always crave a warm breakfast this time of year, so this is a great one to have ready when we wake up. I bet Maddie would even love to eat it, so that’s a win-win!

  2. says

    I’ve been having a series of oatmeal cravings lately (just has some for breakfast today :-) and this looks delicious! Love the idea of tossing everything in the slow cooker the night before for a yummy breakfast the next day! Trying this ASAP!

  3. says

    I was just thinking about how I should start using my slow cooker to make steel cut oats, since I just don’t have time for it in the morning before work. This recipe sounds delicious! I’m totally putting this together tonight so I can enjoy it tomorrow morning!

  4. says

    I love this recipe! So easy to make and will fit perfectly into a cleanse I am doing next week for 3 weeks! I made something like this years ago and totally forgot how easy and delicious it can be, thanks!

  5. Leah says

    This looks wonderful…I’m just wondering if it can be made with old fashioned oats instead of steel cut oats. (Only because I really want to try it but don’t have any on hand!).

    • says

      Rolled oats would most certainly work! The texture won’t quite be as chewy as steel cut but if you’re ok with a softer texture then go for it! Also you may wish to cut down on he liquids as they won’t require as much. Let me know how it comes out!!

  6. Charlotte Moore says

    I think I will try this with peaches. I love bananas but sometimes they give my husband indigestion. Since it is just the two of us I think peaches would reheat the next day a little better. YUM!!!!

  7. says

    I need to send this info to my husband because he doesn’t believe me when I tell him the importance of breakfast. He thinks a cup of coffee is all he needs, when in fact it’s not doing him any good. Your slow cooker oatmeal looks fabulous!

  8. Kerry says

    This sounds great! Definitely want to try it. What size crockpot is recommended? I only have a 6 quart, i’m thinking I need to invest in a smaller one.

  9. Carol says

    I makes slow cooker oatmeal all the time and have several variations of flavors (Apple & cinnamon, pumpkin spice etc). I have found cleanup is so much easier if you put all ingredients in a glass bowl that fits into the slow cooker, then add water to the cooker to cover the lower half of the bowl. Cover the cooker and cook on low for 6-8 hrs. The steam action keeps everything nicely creamy and no “crusty” residue on the inside of the slow cooker!

    Here’s one for rolled oats that is good too!
    2c. milk, 1 c. old fashioned oats, 1 c. peeled and diced apple, 1/2 c. raisins, 1/2 c. chopped walnuts, 1/4 c. packed brown sugar (or maple syrup), 1/4 t. salt, 1/2 t. cinnamon. cover and cook overnight on low
    I mix up the fruit and the options are endless!

  11. says

    i really can’t figure out why I haven’t tried a slow cooker overnight oatmeal recipe yet. It’s kind of ridiculous that I’ve waited so long!

  12. says

    I tried this today and it was amazing! I have been looking for a more filling breakfast option and this is definitely a win. I have never made my own oatmeal and was a little nervous about using flax seed (never used that either). I added 1 more banana (we love bananas), 1tbs of brown sugar to the recipe. I will be making it again.

  13. Marisa K says

    I love oats in the morning! Are steel cut oats the same as regular oats? Do you have to steal them for them to be steel cut :p

  14. Scott Silverman says

    Looks great, is there an alternative to a slow cooker? can it be made, put in fridge overnight and heated in morning??

  15. Jen says

    This looks AMAZING! I really, REALLY want to like oatmeal and I feel like this is my last ditch effort. Got everything and will be making tonight :)

  16. says

    Woke up early and realized I was out of quick oats and had all the other ingredients, so I just threw it into the slow cooker. Used chia seeds instead of flax. Going to have this before a super long run tomorrow…Thanks for sharing!

  17. Krista says

    This may be a weird question, but do you think this recipe would work with barley? I always buy old fashioned oats, and don’t have any steel cut on hand, but I have not had as much luck with the old fashioned in my crock pot. They seem to get way too mushy. I’m wondering if barley would hold up a little better?

  18. Shelley says

    WOW! I made a double batch of these last night and oh-my-goodness! We have never tried steel cut oats before and now I ask, “Where have they been all my life?” I just finished my first delightful bowl of these, topped with a sprinkle of sugar and drizzle of half-n-half and they really hit the spot on this chilly morning! Now I have lots of leftovers to portion out to bring to work for breakfast. I did reduce the liquid to 3 cups per cup of oats and cooked for 6 hours…the texture is perfect…chewy-good! Thanks for this wonderful recipe!

  19. Kristine says

    Can this be over cooked?? I just tried it last night and the oats are burnt on top and totally overcooked. It was probably in the crock pot for about ~9 hours. Do you have to be very careful about taking it out at 8 hours?

    Thank you!

    • says

      Hi Kristine,

      Does your crock pot automatically switch to Warm after 8 hours? Did you add the same amount of liquid? Also, what types of oats did you use? We make this often and LOVE it – especially this time of year – so I want to make it a success for you too!

  20. Alysonne Hatfield says

    I tried this last night and really enjoyed it for breakfast today. I topped with a little bit of brown sugar only, but I’ll add some banana tomorrow. Next time, I’ll follow the advice about using a smaller glass bowl in the crockpot and a water bath, or maybe just use a shorter cooking time. My slow cooker is a 7 quart, and it’s just too big for this recipe as is – it dried out a little! But it was still a great way to have a hot breakfast on a weekday with minimal effort.

  21. Briana says

    I was wondering if the flavor or texture would be seriously compromised if I used more water in place of the milk?

  22. Damaris Rodriguez says

    I would like to make the Slower Cooker Banana Nut Oatmeal, the ingredients sound delicious and I love oatmeal. What size of slow cooker did you use?
    Thank you,


  1. […] I forgot to post my recipes for yesterday too. For breakfast I made a crockpot banana nut oatmeal (delicious!) I didn’t snap a picture because well, to be honest, it doesn’t look as good as it tastes! But.. you can find the HERE:  recipe […]
