This apple baked oatmeal is a cozy, make-ahead breakfast made with tender apples, warm cinnamon, and hearty oats. It’s perfect for busy mornings, meal prep days, or anytime you want a comforting breakfast that reheats beautifully all week long.
If you love baked oatmeal recipes like my blueberry baked oatmeal, this apple version is a must-make, especially during apple season (hello, autumn!) or or when you’ve got a few apples sitting on the counter that need an action plan.
Why This Apple Baked Oatmeal Works
- Kid-approved
- Holds together in slices
- Not overly sweet
- Freezer-friendly
- Uses pantry ingredients
This is one of those breakfasts that feels special but fits real life.
And while I love serving up slices of apple crumb bars or Air Fryer apple crisp this time of year, I thought something might be a little more appropriate for breakfast.
Ingredients You’ll Need
This apple baked oatmeal uses simple, everyday ingredients you likely already have on hand:
- Apples - Firm apples like Honeycrisp, Granny Smith, Fuji, or Pink Lady work best. They hold their shape and don’t turn mushy while baking.
- Oatmeal - you can use old fashioned or rolled oats. I don't recommend steel cut oats or quick oats for this recipe. To keep this gluten free, use certified gluten-free oats
Baking powder - helps keep these lighter and helps the oatmeal bake to rise - Spices - cinnamon and nutmeg, both of which are in apple pie spice. Makes total sense in this recipe!
- Eggs - eggs work to bind the oatmeal together so we can pick up slices and eat them on the go
- Brown sugar - just a little for a touch of sweetness
- Whole milk - this is my personal preference to keep the oatmeal from becoming dry. You can also use 2% milk.
How to Make Apple Baked Oatmeal
- Step 1: Whisk together the wet ingredients in a large bowl.
- Step 2: Stir in oats, baking powder, salt, cinnamon, and diced apples.
- Step 3: Pour the mixture into your baking dish and spread evenly.
- Step 4: Bake until set, lightly golden, and your kitchen smells amazing.
Let it cool slightly before slicing. The texture sets up even more as it rests.
Now pour yourself a steaming cuppa coffee (or maybe an apple cider mimosa) sit back, and relax.
Pumpkin Oatmeal Breakfast Bars are another great make ahead oatmeal recipe.

- Add a pinch of nutmeg or allspice
- Stir in chopped pecans or walnuts

- Serve with a drizzle of maple syrup or a splash of warm milk
It’s still very much apple baked oatmeal, just made a little fancy. Oh, and you can get a protein boost by adding a scoop of vanilla protein powder or serving with yogurt. (I love vanilla).
Apple Baked Oatmeal Variations
- Substitute maple syrup for the brown sugar. Or, reduce the amount of brown sugar if you like to just a few tablespoons.
- Change up the milk to use oat milk or almond milk
- Swap out the pecans for walnuts, or omit them all together
- Use honey or agave nectar in place of the maple syrup
- Add raisins or dried cranberries for a fall twist.
Make-Ahead & Meal Prep Tips
This apple baked oatmeal is a meal prep MVP when made ahead of time.
- Refrigerator: Store covered for up to 5 days
- Freezer: Freeze individual slices for up to 3 months
- Reheating: Reheat the entire pan on a low temperature in the oven, or warm individual slices into the microwave with a splash of milk
This is one of those breakfasts I always recommend making on Sunday so weekday mornings are easier.
