Reasons You’ll Love This Recipe

  • Convenience: I love being able to wake up to a hot, ready-to-go breakfast that I know my kids will eat and that will keep them satiated until lunch!
  • Healthy & Hearty: Steel-cut oats are rich in antioxidants, fiber, and protein. Not only are these good for you, but they will keep you feeling fuller longer.
  • Customizable: This recipe is great for adding or substituting items to suit your taste preferences.

Ingredients for Slow Cooker Apple Cinnamon Oatmeal

This slow cooker oatmeal is great for using up oats in your pantry and any fruit you may have on hand. I love the simplicity of adding apples, raisins, and cinnamon, but feel free to try other flavors and mix-ins! I have a few ideas listed below. Exact measurements can be found in the recipe card below.

  • Steel-Cut Oats: Buy steel-cut oats instead of old-fashioned oats. Without them, your slow cooker oatmeal will turn out mushy.
  • Cooking Liquid: Water, milk, or nut milk works great here! I used both almond milk and water. This is a great recipe for a dairy-free breakfast!
  • Cinnamon: I love adding cinnamon to oatmeal because of its warm, comforting flavor. Apples and cinnamon is a classic flavor combo!
  • Chopped Apples: Use your favorite type! I always go for sweet apples like Fuji or Honeycrisp. If you want more tart apple flavor, use Granny Smith apples instead!
  • Sweetener: You can use whatever sweetener you’d like! You can use brown sugar, honey, maple syrup, granulated sugar, stevia, etc. Start out with a small amount and add until you’ve reached your desired sweetness and flavor.

How to Make Cinnamon Apple Oatmeal Overnight

All you have to do is throw all of the ingredients in your crock pot and let it do its thing! You’re going to love waking up to these apple cinnamon overnight oats. It takes some of the chaos out of busy mornings with the kids!

  1. Add Fruit and Cinnamon: Put chopped apples, cinnamon, and raisins in the slow cooker.
  2. Add Oats: Next, add one cup of steel-cut oats.
  3. Pour Over Cooking Liquid: Pour the 4 cups of liquid into the slow cooker.
  4. Cook: Cover and cook on low for 7 hours.

Toppings and Mix-Ins

Slow-cooker oatmeal is great for adding all of your favorite flavors and toppings! Here are some of my personal favorites to help give you some ideas.

  • Add Nuts: Chopped nuts add tasty flavor and great texture to the oatmeal. They perfectly balance out the creaminess of the oats. Chopped pecans, walnuts, and slivered almonds are all great additions.
  • Add Protein: Looking to add a boost of protein to your oatmeal? Then, simply add a scoop of your favorite protein powder! Personally, I always use vanilla protein powder because it adds a delicious sweet flavor and creaminess.
  • Toppings: Sometimes, a drizzle of honey or maple syrup is all you need, but if you want to make your breakfast extra decadent, try a little caramel syrup on top!
  • Spices: Spiced breakfasts are perfect for fall! Addย apple pie spiceย or evenย pumpkin spiceย to your oatmeal for an extra fun fallย flavor.

Storing Leftovers

It’s easy to have leftovers of a big batch of slow cooker oatmeal. Keep them! They make breakfast easy throughout the week!

  • In the Refrigerator: Store leftover oatmeal in an airtight container for up to 1 week.
  • In the Freezer: Store oatmeal in a freezer bag for 2-3 months. Thaw overnight in the fridge before reheating.
  • Reheating: I add a little bit of milk to leftover oatmeal to make it nice and creamy again. Then, I pop it in the microwave for 30-second intervals or until warm and smooth.

  1. I have a question-could I slow cook it for 8-8 1/2 hrs (due to sleep schedule)? This sounds wonderful as we love steel oats. Thanks

  2. Hi there! Just wondering how many this serves? I’d like to make it for a brunch…usually 1 cup of old fashioned rolled oats cooked on the stove is just 2 servings….but that would seem really small for this recipe…Thanks!!

  3. This looks and sounds delicious, Alyssa! I cooked steel cut oats, on the stove, Wednesday night so it would be ready to reheat for breakfast Thursday morning. While I was cooking it and the milk/water mixture was frothing up and boiling over, I thought I bet I could do this in the crockpot and here is your recipe. I will be trying this tonight. Thanks for sharing!!

  4. Ooh…I have some steel cut oats in the pantry! Pinning to try. Thanks for stopping by and leaving such a sweet comment! I am now following you on FB ๐Ÿ™‚

    1. I tried to look and it didn’t say an exact size on it! I didn’t use my big one that I use most of the time, I used one size smaller. Sorry this probably isn’t much help! :/ Let me know if you make them how they turn out!
