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.

Ingredients

  • 2 cups rolled old-fashioned oats

  2. In a large bowl, mix together rolled oats, cinnamon, baking powder, salt, almond milk, applesauce, maple syrup, flaxseed, coconut oil and vanilla.
  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. 
  5. Bake: Bake about 40 minutes or until the center has set and a toothpick comes out clean. Allow baked oatmeal to cool just a bit before serving. Serve with a drizzle of almond butter, almond milk, or maple syrup.

      This be mixed up the night before and left in the fridge to bake in the morning?

        Hey Stephanie – I wouldn’t combine all the ingredients together and let them sit overnight because the oats will soak up a lot of the liquid. This is what I would do if you wanted to prep it in advance:

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

      This apple cinnamon baked oatmeal is delicious! It was so easy to meal prep and eat for breakfast all week. It was also great with ice cream straight out of the oven when it smelled too good to wait until morning to try. Like a healthy apple crisp!

      LOVE all your baked oatmeal’s but I think this one is my (and my husbands) favorite. I’m making it today to meal prep for maternity leave. Any tips on freezing and reheating?
      I plan to make and cook it and the let it cool, cover with foil and then freeze but when it comes to reheating I’m stumped!
      I’ll take any tips! Thank you!

        So glad you’re loving the baked oatmeal recipes, Suzanne!! And yes, you can definitely freeze them. When freezing, I typically portion the baked oatmeal out and freeze individual servings to make it easier for reheating. To reheat individual portions, set oven or toaster oven to 350ºF and bake for 5-10 minutes. You can also reheat in the microwave for 1 minute. Once warm, add your toppings if using and enjoy!

      These apple cinnamon oats were so good I had a slice for breakfast AND for dessert! It tastes like an apple crumble and makes the house smell incredible. I omitted the applesauce and added chopped walnuts for crunch. Yum, can’t wait to have more for breakfast tomorrow morning! Thank you for yet another delicious baked oatmeal recipe! 🙂

      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

      1. Brittany Mullins
        January 2, 2021 AT 9:21 am

        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. 🙂
