Apple Cinnamon Baked Oatmeal

This apple cinnamon baked oatmeal is inspired by traditional Amish baked oatmeal and studded with apples, raisins and loads of cinnamon flavor. It’s vegan, gluten-free and great for meal prep.

I’ve said it before and I’ll say it again… baked oatmeal is the best thing since overnight oats! I’ve been on a baked oatmeal kick this year and I’m so glad you’re just as obsessed as me because that means I get to keep trying and sharing new flavor combinations.

Each month, I’ve been making a seasonal baked oatmeal flavor and this month we’re going with apple cinnamon. Late September is the start of apple season so the timing is perfect. Head to a local apple orchard or grab some fresh apples from your local market and whip up this delicious apple cinnamon baked oatmeal.

This apple baked oatmeal is inspired by one of my favorite seasons: fall! I love visiting apple orchards and creating alllll the apple recipes. My ideal weekend would involve a cool, crisp morning, a cozy sweater and some sort of baked apple treat.

Who Invented Baked Oatmeal?

Since my obsession with baked oatmeal, I’ve been determined to figure out who invented baked oatmeal. I’ve yet to find the answer, but a lot of the old baked oatmeal recipes I’ve found come from the Amish, who made baked oatmeal to fuel their long days working on the farm.

Most of the Amish baked oatmeal recipes involve apples, raisins, and cinnamon so the recipe I’m sharing is inspired by that flavor combination, but without the butter, eggs, and milk! We’re keeping things vegan and dairy-free for my version!

I’ve made a similar version before with steel cut oats, but this version is just as a tasty and cooks up a bit faster. Here’s the baked steel cut oatmeal recipe, if you’re interested.

Ingredients in Apple Cinnamon Baked Oatmeal

  • rolled oats
  • unsweetened applesauce
  • milk – I like using unsweetened vanilla almond milk but you can use whatever milk you prefer!
  • apples and raisins
  • flaxseed
  • maple syrup
  • coconut oil 
  • spices and misc cinnamon, baking powder, vanilla extract, sea salt

How to Make Apple Baked Oatmeal

Baked oatmeal is pretty much just a matter of mixing and baking. Nothing fancy! In a large bowl, start by mixing together the rolled oats, cinnamon, baking powder, salt, almond milk, flaxseed, unsweetened applesauce, maple syrup, coconut oil, and vanilla. Fold in the raisins and diced apples.

Pour the mixture in a prepared baking dish, top with a few extra apple slices and bake at 375ºF for about 40 minutes or until the center is set.

This apple cinnamon baked oatmeal recipe is absolutely delicious with a drizzle of almond butter, a splash of almond milk, or maple syrup on top.

Can You Make Baked Oatmeal Ahead of Time?

Yes, you can totally make baked oatmeal ahead of time. There are a couple options that work really well.

Option 1: Bake and Then Reheat Before Serving

  1. Prepare baked oatmeal as the recipe suggests. Once baked, let the oatmeal cool, cover the baking dish and place in the fridge. You can do this 1-2 days in advance. When ready to serve, take oatmeal dish from fridge, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set toaster oven to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.

Option 2: Prep as Much as You Can Without Baking

  1. Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
  2. Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
  3. In the morning, simply mix the wet and dry ingredients together, pour oatmeal mixture into your prepared baking dish and bake as recipe suggests.

  3. Fold in raisins and 3/4 cup of the diced apples.
  4. Pour mixture into prepared baking dish and top with remaining 1/4 cup of diced apples.

      I made this with some modifications based on what I had on hand (skim milk, granny smith apples, dried cranberry, butter). It provided 6 days of a great breakfast that really staved off hunger for hours. It takes longer to warm up in my toaster over (I blame the appliance) so I re-warm at 425. Really appreciate the recipe. Thank you!

      I have steel cut oatmeal and wonder how to substitute. Do I cook the steel cut first and then proceed? Cook the steel cut to “undercook” ? Thank you

        Hi Maggie! I would use my recipe for apple baked steel cut oatmeal. You won’t need to cook them first and it’s delish!!

      This looks amazing! Only Q I’ve got is, I can’t get my hands on unsweetened applesauce so if I use ‘normal’ sweetened applesauce would it be best to cut out the maple syrup?

      Thanks! I can’t wait to make this 🙂

      1. Brittany Mullins
        December 17, 2020 AT 7:28 pm

        Yeah, I would probably cut down on the maple syrup if you use sweetened apple sauce. You can also make your own unsweetened applesauce at home too. 🙂

      So excited to make this recipe today! I scrolled through the comments to see if anyone had made it in the crockpot but didn’t see. Any ideas for timing if I throw it in the crock pot?

        October 27, 2020 AT 4:23 pm

        Hey Jennifer – If you’re looking for a crock pot recipe, I would make this apple cinnamon oatmeal instead.

      I plan to rate this 5 stars because it sounds delicious!! I’m just curious if I can skip the coconut oil and flaxseed? Making this last minute and didn’t check that I have all the ingredients first. Any thoughts?

      Thank you so much!!

      1. Brittany Mullins
        October 7, 2020 AT 5:49 pm

        Hey Alicia – you could use an egg instead of the flax egg and if you have extra applesauce on hand, you could sub more of that in for the coconut oil.

      Delicious, easy breakfast to warm me up on a cosy fall morning! Amazing with almond butter and a hot cup of tea!
      I kept my apple pieces quite big so they had a nice slight bit of crunch to them, although it meant that the oats didn’t hold together quite as well!
      Thanks for the recipe, perfect for those autumn apple gluts!

      Ok, this is seriously delicious. This has been my meal prep breakfast for 3 weeks now and I haven’t gotten tired of it yet lol! It’s delicious without needing any extra maple syrup on top 😋

      Question: Can I add protein powder to this recipe? Would I need to adjust any of the ingredients? TIA!

      1. Brittany Mullins
        July 13, 2020 AT 1:15 pm

        Ahh yay! That makes me so happy to hear, Erin! So glad you’ve been loving this recipe. You can add protein powder to this recipe. I’d start with 1/2 cup and you should be fine with the ratios as is, but you can always add a bit more liquid if you feel as though it needs some more. 🙂 Let me know how it turns out for you!

          Are there any tweaks I should make if using steel cut oats? I made the mistake of buying a large bag from Costco that I can never make successfully on the stovetop. I have old fashioned rolls oats too but those I can actually cook lol!
