Overnight Slow Cooker Baked Oatmeal

Overnight Slow Cooker Baked Oatmeal Recipe

I really wasn’t sure if this was going to work. I’ve been wanting to try it for some time. I read on my friend Stephanie’s blog that she made it and it worked. I read her advice and tips and decided to go for the ‘overnight’ concept. Because I wanted it nice and warm in the morning for my boys!

It worked.

Totally worked.

Didn’t burn on the edges. Was completely cooked in the middle.

I think it worked well because I have an amazing slow cooker, that can be set to on the half hour allowing me to set it to 5 hours. I sprayed the bejeezus out of the ceramic base. The ‘warm’ setting on my slow cooker is just warm enough to keep it warm, but not so warm that it over cooked or burned the edges. And lastly, I think it worked well because I started it so late in the evening. I’m a bit of a night owl. Steve had crashed out on the couch watching Jimmy Fallon and I headed down to the kitchen to start the slow cooker around 11 pm. (Note: I don’t think you have to stay up this late to start this, but I think it helped it turn out as well as it did!)

Turns out this was a huge hit…among all 5 boys. So much so that it’s going into the slow cooker again tonight. Right after a #BBQHacks Twitter party I’ll be cohosting!

I dare ya to try it…might change your life. It just might.

Overnight Slow Cooker Baked Oatmeal

Yield – 4 servings

Preparation Time – 5 minutes

Cooking Time – 5 hours overnight in the slow cooker


  • 4 cups quick cooking oats
  • 3/4 cup brown sugar
  • 1 Tbsp baking powder
  • 1 tsp salt
  • 2 eggs
  • 2 cups milk
  • 2 tsp vanilla extract
  • Toppings – milk, yogurt, cream, berries, sliced bananas, favorite fruit


  • Whisk the ingredients, minus the toppings, together in a mixing bowl. Batter will be slightly ‘loose.’
  • Generously spray a 5 or 6 quart slow cooker with non-stick cooking spray. Pour the mixture into the slow cooker.
  • Set the slow cooker on low and cook for 5 hours. Keep warm until ready to serve.
  • Serve Overnight Slow Cooker Baked Oatmeal with milk/cream/yogurt and fresh fruit.

To Freeze: Let the oatmeal cool completely, cut into single serving sizes (I usually do squares), and freeze individual portions in plastic baggies.

To Thaw: Drop the frozen oatmeal square into a bowl, and defrost it in the microwave for a minute, then warm it at regular temp for a minute, then add milk or yogurt and any other toppings and gobble it up!

    We buy oats in bulk, so I have 25 lbs of rolled oats to use 😉
    Do you think that would work in place of the quick oats with a little extra cook time, or soaking the oats in the milk first?

    I’ve tried several types of oats and the “best” for long cooking time is Irish steel cut, HOWEVER, as long as they are not instant they will work. I also chop an Apple or two and add along with nuts and raisins!! .This is great as you can keep in refrigerator and reheat any extra if you are single like me.

    Thanks for the recipe!
    I, too, have a simple crockpot.
    For recipes like this, my husband bought me what Lowe’s calls a “Utilitech 15-Amp Digital Residential Plug-In Countdown Lighting Timer” which can be set to turn off the outlet at a certain time (could also be used on lamp when we’re on vacation, for example).
    It costs about $11, but has saved many a meal. :)
