For all the fancy recipes I post, I mainly live on oatmeal during the week for breakfast, especially in the wintertime. It’s quick, easy, healthy and filling, the things that count the most when you are trying to feed your family and get out the door to school. Slow Cooker oatmeal has been around as long as slow cookers themselves have but I never got around to trying it out. Well, check that off the list of things to try. It’s tried, done and was a hit with the whole family!

This slow cooker oatmeal was so fabulous to wake up to a warm breakfast already made in the crock pot and not only that, using steel cut oats which and healthier but take time to cook. I usually don’t have time to make steel cut oats in the morning since they take forever to cook and mornings are crazy as it is, never mind cooking something for 20 minutes or more.

How to Make Slow Cooker Oatmeal

  • Grease the inside of your slow cooker with butter.
  • Place the first 4 ingredients in a crock pot and stir to combine.
  • Cook the oatmeal on low heat for 6-8 hours; all slow cookers vary in heat and cooking time.
  • Serve with the toppings of your choice (brown sugar, maple syrup).

Slow Cooker Steel Cut Oats

You have to use steel cut oats in the slow cooker as they take longer to cook than the other types of oats. If you don’t use steel cut oats then you will have mush! Steel but oats are less processed than the other oats and will hold up to the long cooking time that is needed for crock pot oatmeal.

Are Steel Cut Oats Good For You?

Steel cut oats have more fiber than the other types of oats, so yes, they are good for you! They are recommended by tons of health professionals as a healthy breakfast.Steel cut oats are a fabulous gluten-free whole grain and source of vitamins, minerals, fiber and antioxidants.

Tips and Tricks for Making Slow Cooker Oatmeal

  • Grease the heck out of the inside of your crock pot! It will stick, but if you don’t mind soaking your slow cooker after cooking (and really, they are always crusty after using them)
  • A slow cooker  with a “keep warm” setting is invaluable for this and I can’t suggest more that with your next purchase you make sure your slow cooker has that setting. This took 8 hours on low in my crock pot then stayed warm until we got up. If you have a speedy crock pot however, it make only take 6 hours. I don’t know about you, but I sleep (or try to) more than 6 hours a night!
  • To extend the overnight cooking time, make sure all the contents are very cold! This is a trick I use all the time. Use very cold water and very cold milk and you extend the cooking time a lot!
  • I didn’t add much sugar, you can play with the amount but honestly I would just add sugar on top at the end!

    Sadly, not a huge fan. I’d recommend 1 less cup of water, it was very watery even after allowing it to sit with the lid off for a while to thicken. Was also a bit confused when to add the spices, ended up doing it prior to cooking because that just seemed to make sense.

    In general, would do less water, less cinnamon, more raisins or fruit, and add a sprinkle of salt.2 stars

  2. Barbara says

    Would this recipe feed 6 adults? And would it be good for a fall camping breakfast?

  3. Linda says

    I have made this constantly since discovering it. I have varied it a bit sometimes, making it with light Coconut milk and adding some chai seeds for extra health benefits. All yummy

  4. Fred says

    Hi Karylynn,
    What do you mean by “cloves sprinkle nutmeg and” listed on the ingredients?
    Thanks5 stars

    • Karlynn Johnston says

      The code in the recipe plug-in screwed that up, its’ a sprinkle of cloves and nutmeg!5 stars

  5. Sherry McKay says

    My husband makes this but with apples all the time. Makes a big crockpot full beginning of week and then he just has to mic up rest of mornings.5 stars

    • Jennie Jones says

      The only thing I wonder is: how do you keep the oatmeal from becoming cement on the sides of the Crock-Pot? Does the butter on the sides actually prevent that from happening?

      • Aw says

        I made this last night and woke up to brown soup. I was thinking it seemed like a lot of liquid but I assumed the long cooking needed it or something. There’s hardly any oatmeal in there. I don’t see how it could possibly feed 6. It’s just brown liquid with a small amount of oatmeal. I’m disappointed I wasted so much almond milk on this slop.

  6. Pam Mansveld says

    This looks yummy! Since the passing of my crockpot – RIP – I have been soaking steel cut oats overnight in water with a little lemon juice/whey/acv and it is almost as fast in the morning (10 min) \U0001f60aTry adding mashed sweet potatoes and toasted pecans with maple syrup. I will ask Santa for another crockpot!

  7. Heather Pollock says

    Does it have to be steel cut oats?
    Have you tried pecans and apple in it instead of raisins?

    • The Kitchen Magpie says

      Other oats would be mushy..and apples and pecans would be good!

  8. Kelsie Kelly says

    Crock pot liners work great to avoid a sticky mess and make for quick clean up:)

  9. Rosaline Linhart says

    When we were kids in the early 40’s we would go up to Yorkshire to see our grandparents..there was a war on and heavy rationing. Grandma used to put the porridge on the stove at night to cook,in the morning she would literally “dig” into it ..I swear if you stuck the spoon in the middle of the pot the whole lot would have come up in one lump. If you didn’t eat if for breakfast…you got it sliced and fried in lard for lunch….took years after I grew up before I could eat porridge… its funny now, but it sure wasn’t back then.

    5 stars

  10. BrianLenaghan says

    Do I add all the ingredients to the crock pot, or just the first 4. Thank you

  11. Vern Ledger says

    Will keep on the look out for more for everyone!!

  12. The Kitchen Magpie says

    There are even amazing crockpots at Value Village..awesome retro ones! One day I’ll buy a cool retro one there….

  13. Kimberley Tremblay says

    yummm I definitely want to get a crock pot now!!!!!!! I feel ashamed that I am Canadian and don’t have a crock pot! LOL

    • Aimee says

      My husband likes to take oatmeal every morning to eat a work. I am not a morning person and hate waking up so when I stumbled across your recipe I was intrigued. I went to Walmart and spent $9 on a small crockpot and some liners. I just got up to check on it/pack it up. This is THE BEST OATMEAL I HAVE EVER EATEN! Seriously. I’m going to be eating what’s left over every morning!

  14. SabineVan says

    I think I will definitely be trying this in the coming week!  I may use apples instead of raisins though since one of my kids is a tad picky but this sounds fantastic!

    5 stars

    • thekitchenmagpie says

      SabineVan I’m going to try an apple one next, most likely this weekend! It’s on my list!
