Slower Cooker Apple Cinnamon Steel Cut Oatmeal

A week ago, I asked for some recipe ideas for apples. Reader Kristen sent me her slow cooker Apple Cinnamon Steel Cut Oatmeal. I decided to try it this weekend. I made it on Friday night before I went to bed and it was waiting for us on Saturday morning.

The ingredients were quite simple! It was so easy to make. I simply put all the ingredients in the crockpot and cooked on low for 7 1/2 hours.


  • 1 cup uncooked steel cut oats (do not substitute instant or rolled oats for this recipe)
  • 2-3 medium apples cored –  you can peel or leave the peel on – and cut into small squares
  • 1 1/2 cups water
  • 1  tablespoon of cinnamon (adjust to your taste)*
  • 1 1/2 cup milk
  • 1 teaspoon blue agave sweetener (or sweetener of your choice)
  • 2 -3 tablespoons brown sugar (adjust to your taste)
  • 1 tablespoon of butter
  • 1/4 teaspoon salt
* if you don’t love cinnamon, cut this down to a teaspoon
1. Generously spray non stick cooking spray on your slow cooker.   {Do not skip this step or you will regret it.}
2. Put all your ingredients in the crock pot. Stir and cook in crock pot for 7 1/2 hours on low heat. Go to bed {optional}.
3. Wake up to deliciousness!

    This was yummy, but I think I’ll do a daytime cook on the 4.5 hours suggested as it seems my crockpot also runs high. Also going to do the 1.5 x version to last through the work week as I do oatmeal each day and this will save sooo much time. I used the Truvia stevia/sugar blend, 4 tsp, which is 8 carbs (sugar would be 60). I think 2-3 tsp would be enough as the apples add sweetness already. Thanks for a delicious recipe! Thanks everyone for the tips!

  • I make this all the time….. It’s amazing! Looks crusty…in the morning…but give it a stir… And its fabulous!

  • Laura Yingling – recipe?? sounds delish!

  • Laura

    I just made my weekly oatmeal & fruit muffins (using yogurt) and blueberries this week

  • Tracy

    I’ve made this numerous times! It was recommended by a friend in our FB cooking group. It is delicious and healthy! Enjoy!

  • Wow. All i’ve gotta say is i’m HOOKED on this oatmeal. It’s the only thing my bf & I eat weekdays for breakfast anymore. I make a 1.5x recipe to get us through the week on Sunday eve and it lasts til friday. It’s absolutely delicious, thanks for posting such a wonderful recipe!

    To save on calories, i omit the honey. Thinking I might omit the butter, maybe. We also add in about 1/2c. finely ground flaxseed powder :) oh and we have a large oval crockpot, so this thing cooks in 4 1/2hours easy. PAM the hell out of the crockpot though, that’s my one piece of advice haha. LOVE this oatmeal!!

  • Amanda

    I absolutely love oatmeal (as well as my nieces and nephews). The whole family is going snowskiing this weekend, and I am going to be cooking this as one of the breakfast items. I saw a note about a serving size for 3 adults. I would like to double the recipe, but wasn’t sure if it would fit in the crockpot? What do you think?

    Thanks for posting such precise directions.

  • Christie

    Do you happen to know how to figure out how much sugar to use instead of sweetener? Thanks!

    • Kerry

      I just read online 1 tsp:3/4 tsp sugar to sweetener or sweetener to sugar, not sure which way. I did a 1 to 1 trade off – I’ll know in the morning how it worked out :-)

      • Christie

        Awesome! I looked online but didn’t see anything! I hope it works out for you, def. let me know! I have to go buy the steel oats tomorrow so I won’t be making it until then! haha Thank You!!

        • Kerry

          The flavor was great! Very yummy – I might add a bit more cinnamon/brown sugar next time (we like things sweet). The oats were a bit overcooked, so next time I’m going to cut down the whole process to about 5 hours and see what happens. Finally, although I sprayed the crock pot first, everything stuck

          Overall — WONDERFUL!!!

    Hmm. Not a fancy one. Just low or high. I’m sure I did high. :>

  • Angela G

    The last time I tried steel cut oats in the slow cooker they came out mushy. Yours appear to be the right consistency. Will give them another try!

    • Shannon


      Does your crockpot temp run hot? I find that if the temp is too high or they cook to long, they get super mushy – maybe you can reduce the cooking time.

  • Holly

    I never heard of steel cut oats. Can you get them in a regular grocery store?

    • Jennifer K.

      In my shoprite, steel cut oats are in the organic/healthy foods section. Not in with the oatmeal and cereals.

  • alyson g

    Yummy, wanna try this friday nigth for Sat. morning…do you know how many people this serves?

  • Grace Nelson

    I was wondering if I could use those crock pot plastic liners instead of spraying the crock pot??

    • Shannon


      I am not sure – I Have never used them.

  • Jennifer K.

    Yummmm!! Do you have any idea how many servings this makes? I cook for 12 tween boys plus our family every other weekend. The boys would loooooove to have this sometime. And I would love to not have to get up at the crack of dawn to fix them a hot breakfast! :)

    • cat b

      Yikes! 12 tween boys! Good luck with that one :) I use 1 cup of steel cut oats to 4 cups of water to feed three hungry adult hunters at deer camp every morning. 2 guys and 1 gal. I hope this gives you an idea of how much you may need for the lot of you. Good luck!

  • Beth

    this looks great! And I don’t eat sugar so that makes this recipe even better :) Thanks!

  • Heather

    Yummy yum yum yum. Thanks so much!
