Crock Pot Oatmeal With Apples and Cinnamon

I’m not a huge breakfast person, but I can always go for a bowl of oatmeal. It’s everything that breakfast should be! Warm, sweet, and comforting. I have a great recipe for homemade oatmeal on the blog already, but this recipe is unique because you make the oatmeal in your slow cooker! I don’t know why I never tried it until now! It’s so easy to throw in at night so you have a delicious breakfast to wake up to. My favorite part about the recipe was being able to dump it in the crockpot the night before and quickly serve it as we are running out the door. It is also nice because my husband leaves pretty early, so he is able to grab some before he leaves.

As easy as this slow cooker cinnamon apple oatmeal is to make, it’s absolutely delicious as well! It’s jam-packed with tasty flavor and texture from the chopped apples, raisins, and cinnamon. And did I mention cleanup is a breeze? Anything you can make all in one pot is a winner in my book! Nothing hits the spot quite like a warm, hearty breakfast. Your family is going to love this tasty overnight oatmeal and ask for it again and again. Good thing it’s so easy to throw together! If you’re looking for more quick and easy breakfast recipes, you’ll have to try this overnight breakfast casserole as well!

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 just adding apples, raisins, and cinnamon, but feel free to try out other flavors and mix-ins! I have a few ideas listed below. Note: all measurements can be found in the recipe card below.

  • Steel-Cut Oats: Make sure that you buy steel-cut oats instead of old-fashioned or rolled oats. Your slow cooker oatmeal will turn out mushy if you don’t use steel-cut oats.
  • Cooking Liquid: Water, milk, or nut milk work great here! I used both almond milk and water. This is a great recipe to make if you’re wanting a dairy-free breakfast!
  • Cinnamon: I love adding cinnamon to oatmeal because of the warm, comforting flavor it gives it. Plus, apples and cinnamon is a classic (and delicious) 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, try using Granny Smith apples instead!
  • Sweetener: You can use whatever sweetener you’d like here! Add brown sugar, honey, maple syrup, granulated sugar, stevia, etc., until you’ve reached your desired flavor.

How to Make Cinnamon Apple Oatmeal Overnight

Breakfast recipes as easy as this slow cooker oatmeal are hard to find! 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 having it to wake up to. 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 steal 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 to! Here are some of my personal favorites to help give you some ideas.

  • Add Nuts: Not only do chopped nuts add tasty flavor to the oatmeal, but great texture, too! They balance out the creaminess of the oats perfectly. Chopped pecans, walnuts, and slivered almonds are all great additions.
  • Add Protein: Looking to add a boost of protein to your oatmeal? Add a scoop of your favorite protein powder! I always use vanilla protein powder to add 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! Try adding apple pie spice or even pumpkin spice to your oatmeal for an extra pop of 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 because it helps to make it nice and creamy again. From there, 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 🙂

    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!
