What’s Special About this Apple Baked Oatmeal?
There are so many ways to make baked oatmeal. This extra healthy, vegan version relies on flax and applesauce to bind everything together, apples and applesauce to sweeten, and nuts and apple chunks for texture.
For this apple oatmeal, we’ll be using apples in three different forms: chunks, slices, and applesauce (image 1). The best part of this recipe, though, is the unique way we’re using the apple slices.
Here are the 3 types of apples used in this recipe We place sliced apples on the bottom of the baking dish to add natural sweetness, then bake until gooey We top our baked apple slices with a delicious oat mixture and then bake to perfection!
Basically, you’ll add sliced apples to the bottom of your baking dish (image 2), par-bake them for a few minutes, and then add the oatmeal mixture on top.
The apple slices on the bottom become soft, syrupy, and luscious, while your baked oatmeal on top becomes chewy, beautifully browned, and a bit crispy (image 3). This combination of textures is fabulous.
About the Ingredients
This baked oatmeal is simple and satisfying. It’s made with a handful of wholesome, easy-to-find ingredients that you probably have in your pantry already. Here’s what you’ll need:
- Rolled Oats: A hearty, inexpensive pantry staple. Look for rolled or old-fashioned oats for this recipe and, for best results, do not substitute another type. To keep this recipe gluten-free, choose certified gluten-free oats.
- Sweet Red Apples: Since there’s no sugar added to this recipe, find the sweetest, ripest apples possible. Gala or Fuji apples are good options.
- Unsweetened Applesauce: Adds moisture to this baked oatmeal and replaces the oil/butter/baking powder you typically find in baked oatmeal.
- Flax Eggs: A simple combination of ground flax and water, it gels up and helps everything bind together.
- Soy Milk and Apple Cider Vinegar: This combination makes vegan buttermilk. The ACV curdles the soy milk and gives this recipe a tangy flavor.
- Tips: Not all types of non-dairy milk will curdle, so I recommend sticking to soy milk if possible. If you don’t have apple cider vinegar on hand, white vinegar or lemon juice will also work well.
- Chopped Nuts: Chopped nuts make this oatmeal extra satisfying, and provide additional texture. I recommend walnuts or pecans, because they scream fall to me, but use whichever nuts you prefer.
- Ceylon Cinnamon, Nutmeg, Vanilla Extract, and Salt: A classic combination that is just plain delicious. (I recommend Ceylon Cinnamon because it has more health benefits, but you may use the type you have on hand.)

How to Make Baked Oatmeal
This baked oatmeal has quickly become a favorite in our home. Though it has a few more steps than I typically like ;), the steps are actually really easy. The instructions are also laid out so that you can get as much multi-tasking done as possible AND keep your time spent in the kitchen to a minimum.
In a nutshell, here’s what you’ll do to get this Apple Baked Oatmeal on your table:
- Preheat your oven.
- Make flax eggs. This is easy–just combine ground flax and water.
- Make vegan buttermilk. It sounds fancy, but it’s just soy milk and apple cider vinegar.
- Slice 1 red apple, add the slices to the bottom of your baking dish, then bake in the oven for 10 minutes.
- In the meantime, chop up another apple (this is “apple” baked oatmeal, after all). Then combine all remaining ingredients so you have a thick oat mixture.
- Remove your partially baked apples from the oven and spread your oat mixture on top of them.
- Return your dish to the oven and bake until the top of your oatmeal is browned and a bit crispy. Done!

How to Top Your Baked Oatmeal
With this recipe, you can feel confident that you’re getting plenty of nutrition to start your day! In fact, this recipe checks a lot of healthy boxes: whole grains, fruit, nuts, flax, and spices.
I typically eat this Apple Baked Oatmeal as-is, and find it to be delicious, warm, and comforting. If you want to add a little extra pizzazz, try out the following.
(Optional) Topping Ideas:

- Additional fresh or dried fruit (on top or on the side)
- A drizzle of raw nut butter
- A few chopped dates

How to Store & Reheat
This baked oatmeal is a perfect make-ahead breakfast. It’s inexpensive, makes a few servings, and is easily reheated for breakfasts throughout the week. It’s also equally delicious cold out of the fridge, as a healthy afternoon snack!
To store, slice your cooled oatmeal and place it in well-sealed glass containers. Stored tightly, leftover baked oatmeal will keep well for at least 5 days in the fridge. To reheat, microwave lightly until warmed through.
I hope that this Apple Baked Oatmeal gives you all the fall feels AND makes your week a little easier!

Apple Baked Oatmeal
This Apple Baked Oatmeal is the perfect fall breakfast. It's full of healthy, plant-based ingredients, lots of syrupy fall apples, and absolutely no oil, butter, or sugar. Get a dish of this vegan oatmeal in your oven ASAP and prepare for your kitchen to smell like autumn!
Ingredients
- 2 tablespoons ground flax
- 6 tablespoons water
- 1 and 1/4 cups unsweetened soy milk
- 1 tablespoon and 1 teaspoon apple cider vinegar
- 2 medium-sized sweet and crisp red apples (such as Gala or Fuji)
- 1/2 cup unsweetened applesauce
- 1/3 cup chopped pecans or walnuts
- 2 cups rolled oats (certified gluten-free, if necessary)
- 1 and 1/2 teaspoons Ceylon cinnamon
- 1/2 teaspoon nutmeg
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
Instructions
- Preheat your oven to 350 degrees Fahrenheit.
- Make your flax eggs: Add ground flax and water to a small bowl. Stir well and set aside.
- Meanwhile, make your vegan buttermilk: In a large mixing bowl, combine soy milk and apple cider vinegar. Stir well and set aside.
- Thinly slice 1 red apple. Add apple slices to the bottom of your pie plate in a single, even layer. (Reserve a few apple slices for topping, if desired.) Once your oven is preheated, bake apples for 10 minutes.
- In the meantime, chop your remaining apple into chunks.
- To your large mixing bowl of vegan buttermilk, add all remaining ingredients (applesauce, apple chunks, prepared flax eggs, nuts, oats, cinnamon, nutmeg, vanilla extract, and salt). Stir until well combined.
- At this point, your baked apples will likely be ready. Remove your pie plate from the oven. Add your oat mixture on top of the baked apples and spread into an even layer. Top with a few reserved apple slices (optional).
- Return the hot dish to the oven. Bake at 350 degrees for 30 minutes, until the top is browned and a bit crispy.
- Cool for at least 10 minutes before slicing and serving. This oatmeal is delicious fresh from the oven, cold from the refrigerator, or reheated (briefly) in the microwave. Well-sealed leftovers will keep for at least 5 days in the fridge.
Notes
- Since there's no sugar in this recipe, it's important to choose sweet apples.
- I have specified Ceylon cinnamon in this recipe, but you may use the type of cinnamon you have on hand.
- If you follow a very low-fat diet or if you prefer a sweeter oatmeal, feel free to switch out the nuts for dried fruit instead. Simply substitute an equal amount of dried fruit, such as raisins or chopped dates, for the nuts.
- If you don't have a 9-inch pie plate, feel free to use an 8x8 square baking dish instead, with good results. (No need to change the baking time.)
- If you use any other size baking dish, be sure to start checking your baked oatmeal after 20 minutes, since your cooking time will vary.

This looks great! However, the print version has instruction for a different recipe…one that involves Tofu. Not Apple Cinnamon Baked Oatmeal.
