What is Baked Oatmeal?
If you’re new to baked oatmeal, it’s kind of like bread pudding, but made with oats instead of chunks of bread. It’s sweet, rich, hearty, and absolutely amazing. The texture is soft and moist, but not goopy like traditional oatmeal can be, and it gets just a little bit crispy around the edges of the baking dish. You can eat it hot out of the oven and the leftovers can be eaten cold or reheated in the microwave. I like to pour a little cold milk over top for a delicious hot-cold combo. Baked oatmeal can also be frozen in single-serving containers for quick reheatable weekday breakfasts!
Ingredients for Apple Cinnamon Baked Oatmeal
This apple cinnamon baked oatmeal combines our usual baked oatmeal base with apples that are coated in a little cinnamon and sugar, and then baked until they form an apple pie-like layer on the bottom of the oats. Here are the ingredients you’ll need to make this incredible apple cinnamon baked oatmeal:
- Fresh apples: Pick a sweet or semi-sweet variety of apple, like Fuji, Gala, or Honeycrisp. And, of course, take advantage of the fresh fall apples for the best price and flavor!
- Oats: Make sure to use old-fashioned rolled oats for this recipe, not quick oats or minute oats, to achieve the best texture. Quick oats are too thin and will create a mushier texture.
- Milk and eggs: Milk and eggs create a custard that keeps the baked oats soft, tender, and moist. I like to use whole milk, but you can substitute it with non-dairy milk if needed.
- Brown sugar and applesauce: Using both broth sugar and applesauce to sweeten the baked oatmeal creates an even bigger apple pie-like flavor without having to use too much added sugar.
- Spices: Cinnamon, cloves, and vanilla make these baked oats that classic fall aroma!
- Lemon juice: A little lemon juice brightens up the baked apples and really makes their flavor shine.
- Cornstarch and baking powder: These two ingredients are added for texture. The cornstarch helps thicken the apple juices as they bake, creating a pie-filling-like texture. The baking powder lightens the oat mixture just a touch so it’s not quite so heavy.
How to Serve Apple Cinnamon Baked Oatmeal
Baked oatmeal is pretty versatile. You can eat it either hot OR cold. I love it just out of the oven with a little cold milk poured over top, but it’s also great cold after it’s been refrigerated overnight. You can top it with some nuts or even some whipped cream for an even more dessert-like treat!
How to Store The Leftovers
After baking, divide the oatmeal into single-serving portions and refrigerate until completely cool. The baked oatmeal can be stored in the refrigerator for 4-5 days, or you can transfer it to the freezer for longer storage (about three months). Refrigerated or frozen baked oatmeal can be reheated quickly in the microwave.

How to Make Apple Cinnamon Baked Oatmeal – Step by Step Photos
Preheat the oven to 375ºF. Core and dice four medium apples (about ½ lb. each).
Place the apples in the bottom of a 9×9-inch or 2-quart casserole dish. Add 1 Tbsp lemon juice, 2 Tbsp brown sugar, 1 Tbsp cornstarch, ½ tsp cinnamon, and ⅛ tsp cloves. Stir until the apples are evenly coated in sugar and spices.
Cover the dish with foil and bake the apples for 15 minutes in the preheated 375ºF oven.
While the apples are baking, begin preparing the oat mixture. In a large bowl, whisk together 2 large eggs, 1.5 cups unsweetened applesauce, 1 tsp vanilla, 1 tsp salt, 1 tsp baking powder, 1 tsp cinnamon, and ¼ cup brown sugar.
Add 1.5 cups milk to the applesauce mixture, then whisk again to combine.
Add 2.5 cups rolled oats (not quick oats) and stir until everything is evenly combined.
After the baked apples come out of the oven, give them a stir, then pour the oat mixture over top of the apples. Place the dish back into the oven (uncovered) and bake for 30 minutes more.
After 30 minutes the oats should be golden brown around the edges and you might see some of the apple cinnamon layer bubbling up around the edges. Remove the baked oatmeal from the oven and let it cool for about 5 minutes before serving.
The bottom layer will be sweet and tender baked apples and the top layer will be a soft baked oatmeal. SO GOOD!
I like to eat my apple cinnamon baked oatmeal with a splash of cold milk on top!
This is my favorite of the baked oatmeal recipes on this site. I make a big batch of homemade applesauce and keep portions in the freezer just to use for this recipe. I find Gala apples make the best sauce. Just core the apples, no need to peel. Cook with a bit of water or cranberry juice until soft and then puree with an immersion blender. For the baked oatmeal layer I add a few scoops of protein powder to give it an extra nutritional boost. Served warm with a dollop of Greek yogurt it makes a fabulous breakfast.
Another good oatmeal bake! Question: could you use canned apple pie filling?
Hmmm… We haven’t tried it, but I think it could work! I would just skip that first step of baking the apples. Pour in the apple pie filling and then top with oatmeal mixture. There’s a chance it may come out a bit more wet though so keep that in mind.
Wow! This is delicious! My husband was skeptical at first but he loved it so much, he went back for seconds! As he was eating it, he said that maybe next time I could add walnuts. I wanted to test this recipe out before Christmas. I believe my guests are going to love it!
Yum! Another winner. I was a little worried the apples might stick to the bottom of the pan with no oil/cooking spray, but they didn’t! Turned out great and made the apartment smell wonderful. What a great way to welcome fall.
A-MAZ-ING! Thanks for this deliciousness!
It was phenomenal with apples and I made it today with peaches! I only had 1/4 c applesauce so I added ~ 3/4 c extra coconut milk, and then it seemed too wet so I added an extra 1/5 c oatmeal. It came out perfect! I’ve been serving it with a big dollop of Greek yogurt and couldn’t be happier. This is perfect for breakfast or dessert-I’m so happy I found this recipe!
Was very mushy the next day for meal prep.
Yes, the texture of baked oatmeal is supposed to be soft. :)
Try freezing it next time. Dry sitting right next to wet for 24 hours = mushy
I thought this recipe was great. Not as sugary and decadent as a lot of baked oatmeal recipes while still being really delicious. And the second layer could actually be fully prepared while the first layer was in the oven :) which is rare in my experience.
This recipe turned out really well. A few things I changed slightly: I used full-fat oat milk rather than dairy milk, and I didn’t have lemon juice so substituted with about 2/3 tbsp water and 1/3 tbsp apple cider vinegar. I also baked it for longer than 30 minutes, putting it back in for 2 or 3 minutes a few times until the top had a little more golden-brown to it. All of our ovens are going to be slightly different, so the important thing is to look out for signs that something is done rather than follow the exact timing in the recipe.
I will definitely be making this again!
Excellent. Very custard like an so creamy.
I used flax eggs and soy milk for a more plant-based recipe, and it worked great! I also added about a scoop of vegan vanilla protein powder and it blended in really nicely!
The apples turned out SO perfect! I’m officially obsessed. It’s like a healthy apple crisp.
My hubby wasn’t interested in trying the banana-blueberry baked oatmeal (despite his being a blueberry fan), but he liked this one and had several of the servings, hooray! I didn’t have cloves so I subbed 1/2 cinnamon and 1/2 nutmeg. I ADORED the way this made my home smell! I may have to make it again with gala apples. Thank you, Beth!
Does anyone know if this can this be frozen?
Yes, baked oatmeal freezes great! :)
Thank you 😁
I made four giant servings for 415 calories each, made exactly as is but with unsweetened almond milk. I didn’t think it was too salty per another commenter.
Update: I also made this with 3 pears instead of apples, with everything else the same, and it was awesome!
I love your baked oatmeal recipes, and I’ve used them several times. This was my first time making the apple pie ones, and I was surprised that there was so much more salt than in other recipes. I’ll definitely be cutting the salt in half in the future, otherwise it was wonderful.
Thank you for the simple and tasty recipe! I’ve made it twice now. The second time, I had an extra apple and strawberries so I made my own strawberry applesauce for the recipe and it turned out delicious.
Has any one tried substituting honey for the brown sugar?
Maple syrup works really well!
