Apple Cinnamon Oatmeal | Slow Cooker or Instant Pot

Tuesday, October 29 is National Oatmeal Day! Needless to say, this a holiday I’m happy to celebrate because I love oatmeal and have a ton of healthy oatmeal recipes to prove it. On Tuesday night I made a big batch of steel cut apple cinnamon oatmeal in my slow cooker. I’ve made overnight steel-cut oats on the stove top before, but never cooked them in my slow cooker so I was apprehensive about how it would turn out.

I put the ingredients for the apple cinnamon oatmeal together and started the slow cooker around 10PM, went to bed and upon waking up at 6AM, our house smelled like baked apples and my oats were perfectly cooked and waiting for me to dig in — quite a lovely circumstance to wake up to if you ask me. The only thing I needed to whip up was a pot of coffee.

These apple cinnamon steel cut oats are oh so creamy and I love the chunks of cooked apples and warm cinnamon spiciness. The recipe makes four servings of oatmeal so you can share with others (this would be great for a holiday brunch) or use it as a meal prep recipe and save the leftover oatmeal for a quick breakfast throughout the week — just let the leftover oatmeal cool and place in the refrigerator for up to one week. Simply reheat the oatmeal on the stove top or in the microwave. Just add a little water or milk when reheating if it’s too thick.

Instant Pot Instructions

The best part? I’ve tested this apple cinnamon oatmeal recipe in the slow cooker and the Instant Pot so I’m giving instructions for both within the recipe!

I note this in the recipe, but the big difference between cooking the apple cinnamon oatmeal in the slow cooker and the Instant Pot is the amount of liquid. For the slow cooker you need 4 cups of liquid and for the Instant Pot you only need 2 cups. It can be water or almond milk, whichever you prefer. Almond milk will make for creamier oatmeal.

As always, if you try this apple cinnamon oatmeal recipe please be sure to leave a comment letting me know how it turned out. Your feedback is so helpful for the EBF team and other readers!

Prep Time 10 minutes
Cook Time 6 hours
Total Time 6 hours
Servings 4

Ingredients

  • cooking spray, butter or coconut oil
  • 1 cup steel cut oats
  • 2 cups water
  • 2 cups Almond Breeze unsweetened vanilla almond milk*
  • 1 cup chopped apple pieces
  • 1 Tablespoon maple syrup + 5 drops of liquid stevia, or other sweetener of choice
  • 1 teaspoon vanilla
  • 1 teaspoon cinnamon
  • 1/4 teaspoon salt
  • toppings: chopped nuts, nut butter, extra maple syrup, coconut sugar

Instructions
 

  • For the slow cooker: Coat slow cooker with cooking spray, butter or coconut oil. Add all the ingredients besides the toppings into slow cooker and mix well. Cook on low for 6-8 hours. Place in a bowl to serve and sprinkle on toppings of choice.
  • For the Instant Pot: Add all ingredients except the toppings to your Instant Pot, but be sure to only use 2 cups of liquid (water or almond milk) instead of 4 cups. Cover with the lid and turn the vent to "sealing." Press the manual button and set time to 4 minutes on high pressure. The Instant Pot will automatically start. Once done cooking, allow the pressure to naturally release. Once all the pressure has released carefully remove the lid and stir the oatmeal and serve.
  • For leftovers: Let the oatmeal cool and place in a sealed container in the fridge for up to a week. You can reheat the oatmeal on the stovetop or microwave. Just add a little additional milk to loosen the oatmeal, if needed.

Notes

  • The big difference between cooking the apple cinnamon oatmeal in the slow cooker and the Instant Pot is the amount of liquid. For the slow cooker you need 4 cups of liquid and for the Instant Pot you only need 2 cups. It can be water or almond milk, whichever you prefer. Almond milk will make for creamier oatmeal.

      Haven’t tried this yet, but I’m wondering, if I only have rolled oats, what would be the timing for the Instapot? I’ve never liked steel cut oats.

        Hey Lija – I haven’t tried rolled oats in the instant pot, so I’m not too sure. Here’s an instant pot recipe that maybe you could use as a reference! Let me know if you try it and how it turns out.

      I love recipes that are effortless but healthy and tasty. I made this recipe before in my crock pot and what a treat. The leftovers were as delicious as the first dish. I’m about to make another batch – love not having to always think about what’s for breakfast when I wake up. Also want to give kudos to Blue Diamond Unsweetened Vanilla Almond Milk. Use it all the time.

      What other liquid sweeteners s would work? Could I use honey? How much would you recommend, or just use more maple syrup?

        Yes, you can use honey or agave or any liquid sweetener of your choice and it can be subbed 1:1 with the maple syrup!

      Sounds amazing and can’t wait to try this. What do you think about replacing some or all of the water with apple cider or apple juice? Think it would work?

        Definitely! It will just add more sugar, but I bet it’d be delicious!
