apple cinnamon slow cooker steel-cut oatmeal

Steel-cut oats, cooked all night in the slow cooker with apples and lots of cinnamon…  breakfast has never been so easy and the house smells amazing when you wake up!

We all know I love my oatmeal.  Especially when it’s steel-cut and slow-cooked.

This version is a kicked-up version of my original…  I must say, I am a classic girl and the original version is still my favorite, but the kids loved this one and I’m sure I will be making it often!

Oh! … this oatmeal reheats wonderfully, so even if you are making this just for you…  portion it out when it’s done and store in the fridge.  After a quick microwaving with a little milk or water, you’ve got instant breakfast all week!

apple cinnamon slow cooker steel-cut oatmeal


  • 1 cup steel cut oats
  • 4 cups water
  • 1/2 cup milk
  • 1 large apple, cored and finely chopped
  • 1 tablespoon cinnamon
  • 1/2 teaspoon nutmeg
  • 1/2 cup, or so, brown sugar (your preference!)
  • 1/2 teaspoon salt
  • 1/2 teaspoon pure vanilla extract
  • 1 tablespoon butter


Grease your slow cooker insert and then dump all the ingredients in. Stir, turn on LOW and cook overnight while you sleep, 8-10 hours.

In the morning, stir again (as it will still look watery and separated) and it will come right together and be ready to serve!

    This is the BEST overnight oatmeal recipe I have tried. I do like to use 2-3 apples instead of just 1, but everything else is perfect :) Thanks for such a great recipe!!!

    You couldn’t do this with regular minute oats could you?

      They would get pretty mushy I would guess. Couldn’t really hurt to try though?

  • Abbey

    What kind of apples did you use?

  • Danon

    Cook how long overnight?

    • Phil

      I would assume around 8 hours, since that’s how much sleep we should typically get.

    Terrible recipe. I made this last night and woke up this morning to burnt oatmeal. My husband tasted it and said it awful. I followed your recipe and even slow cooked it for 8 hours only. What a waste.
