Slow cooker overnight oatmeal is the perfect way to have a hot breakfast ready to go when you first wake up in the morning!

This delicious slow cooker overnight oatmeal breakfast will be ready for you when you wake up in the morning and you won’t have to lift a sleepy, coffee-deprived finger to do it. True story.

This bad boy will cook all night while you sleep. Yup. A full 8 hours!

Sorry, no, I can’t include the 8 hours of sleep with this recipe. I barely get that myself these days. But I can promise you a “wake-you-up-it’s-so-delicious” breakfast you’ll enjoy again and again this season. And all you have to do is throw it together the night before when you’re still somewhat conscious! How’s that for convenience?


Oats are really a perfect slow cooker food if you get the ratio of oats to liquid just right. The resulting texture after cooking all night is pretty darned perfect. It’s almost like a creamy, sweet risotto that’s been made with great care. Add the right flavors and ingredients, and breakfast will be a thing of beauty.

Note: I don't recommend using any other type of oats with this. Steel cut oats seem to stand up to long cooking times far better than other styles of oats. Also, if you prefer your raisins chewy, add them after cooking. Cooking them makes them very soft. However, if you do not cook them with the oats, you will most likely need more sweetener.

  1. Thanks to finally getting this recipe, been waiting since yesterday!

  2. Margaret R says:

    I make mine up in the afternoon and put my insert in the fridge. The I pop it in the crockpot at bedtime. It is amazing in the morning when I wake up and it smells awesome.

  3. Sounds good to me. Thanks!

  4. Yay!! I’m so glad to find a crockpot oatmeal recipe that I don’t have to get up in the middle of the night to cook!

  5. Sounds interesting. I’ve never tried overnight oatmeal! I will probably have to do so soon!

  6. Mariann Buonadonna says:

    If you have one of those itty bitty crock pots it’s perfect for one serving-divide the recipe exactly in half. I am the only steel cut oats fan in my house. I tried making a bigger batch and reheating left overs, but I prefer them just made.

  7. graciouspantry says:

    I’m not sure what gluten free oats are like. How long do they take to cook? If they are gluten free steel cut oats, then they should be fine. But if they are the quick-cook variety, they probably won’t hold up too well.

  8. graciouspantry says:

    Steel cut oats are very filling, yes. Pair it with some eggs and you’re set to go! 🙂

  9. graciouspantry says:

    Because it will overcook the food. It would be the equivalent of using a tractor to plant one little seed. It’s just too much.

  10. graciouspantry says:

    If you use the proper size slow cooker and use the correct balance of liquid to food, it shouldn’t burn at all. 🙂

  11. Danyalle Friday says:

    I have had my itty bitty crock pot for 5 years now and have never used…thanks for giving me a reason to pull it out!!

  12. Jill Esham says:

    I have done overnight oatmeal for a long time. My favorite is with apples chunks, walnuts and cinnamon. What a great time-saver.

  14. graciouspantry says:

    It rewarms just fine. Use a microwave, or put it in a pot with a little extra liquid to warm on the stove.

  15. graciouspantry says:

    I would think it would be fine made with milk, but I haven’t tried. Apples and nuts should be fine too, just keep in mind that with a slow cooker, you’ll have apple sauce in your oats when it’s done cooking. Not apple chunks. You may want to do a test run of this during the day when you can keep an eye on it to see if it needs any adjustments.

  16. Milk in general does not hold up in a crockpot and leaves a funny taste. Something about it breaking down? I wonder about almond milk or coconut milk?

    1. graciouspantry says:

      Coconut milk does far better in a slow cooker. Almond milk generally does not hold up at all with this type of cooking. I’m sure there are exceptions, but overall, avoid the almond milk here.

  17. I made this for the first time last night and it turned out great. I added sliced almonds for a nice crunch. The only issue I had is it really sticks to the sides of the crock pot, which requires soaking to clean. Also, I used a baby crock pot and this recipe filled it halfway, which was perfect, otherwise a big one just wouldn’t work.

  18. I made this last night and it looked great this morning but was pretty tasteless. I added all the ingredients above except for raisins and also added walnuts. Maybe I should double up on the cinnamon and vanilla or add some other sweetner?

    1. graciouspantry says:

      Sorry about that. The raisins add a lot of sweetness in cooking. So that’s why it didn’t taste exactly right. Yes, you can add more of whatever you like.

  20. I tried making this for the first time a few days ago. I enjoyed it so much that I made another batch and tripled it. I will never make oatmeal on the stove again. I love my crockpot!

    1. The Gracious Pantry says:

      Haha! Wonderful! 🙂

  21. I love cooking oatmeal in the slow cooker overnight. I make a basic oatmeal by adding a few cinnamon sticks instead of ground cinnamon, a little nutmeg, a little salt and vanilla extract. For the liquid i alternate each time I make it depending on what I have on hand. I may use water, soy milk, coconut water, coconut milk or almond milk. Using any of these liquids I found to be tasty. I use a little extra liquid so the oatmeal is creamy. Each morning I add a different add-in such as almond nut butter, banana, apples, peaches, pears, different berries, nuts, cocoa powder, ground flaxseed the list goes on. I also may sprinkle brown sugar, honey or agave nectar if i need a little more sweetness. I don’t like sugar substitutes. This morning I tried Nectarine slices and I didn’t care for it too much. Will not do that again.

  22. Hi,
    Made this last night.
    Smelled amazing when we woke up…HOWEVER…it did not work out.
    I did use a 3.5q. pot but I tripled the recipe – 1.5C Oats, 6 cups water etc.
    WAY too much water!! LOTS of liquid and everything was stuck to the bottom.
    ( not burned at least).
    This will need fine-tuning if you have a larger pot. I have a family and I think I’ll go back to my old standby…Red River Cereal 🙂

    1. The Gracious Pantry says:

      Donna – Ya, any time you double or triple a recipe, you have to make certain adjustments. Sorry it didn’t work out for you!

  23. Sara Berryman says:

    Could you add egg whites to this? Thanks!

    1. The Gracious Pantry says:

      Sara – You could try, but I have a feeling you’d end up with some clumps of rubber egg. It’s probably best to serve them on the side with this one.

  24. I use my slow cooker as a double boiler when cooking steel cut oats. I have a large crockpot, put about an inch of water n the crockpot. Then I put all the oatmeal incredients into a smaller glass Pyrex….u know one of the small round glass ones. I set the pyrex into the large crockpot then put crockpot lid on. I do this almost every night for my hubby and he can just grab the glass Pyrex full of yummy oatmeal as he goes out the door. No cleaning up a messy crockpot.

    1. The Gracious Pantry says:

      Heather – Sounds wonderful! Thanks for the tip!

  25. I can’t wait to try this tonight. I want to add chopped pecans to it also.

    1. The Gracious Pantry says:

      Torre – that would be yummy!
