Our Apple Pie Baked Oatmeal is everything you love about classic apple pie in an easy, wholesome breakfast casserole. Made with tender apples, old fashioned oats, warm cinnamon, and maple syrup, it's perfect for meal prep, holiday mornings, or feeding a hungry family with minimal effort.
Preheat your oven to 375 degrees F and generously grease an 8 x 8 inch baking dish with butter.
Add the rolled oats, cinnamon, nutmeg, salt, and baking powder to a large mixing bowl.
Stir the dry ingredients together until they are evenly combined.
In a separate small bowl, add the almond milk, eggs, maple syrup, and vanilla extract.
Whisk the wet ingredients until the eggs are fully incorporated, and the mixture is smooth.
Pour the wet ingredients into the bowl with the dry ingredients.
Stir until the oat mixture is evenly moistened and fully combined.
Add the diced apples and chopped pecans into the mixture.
Fold in the apples and pecans until evenly distributed.
Transfer the oatmeal mixture to the prepared baking dish and spread it into an even layer. Place the baking dish on the center rack of the preheated oven and bake uncovered for 40 to 45 minutes, or until the oatmeal is set and lightly golden brown.
Remove the baked oatmeal from the oven and let it rest for 5 minutes before serving warm with maple syrup, Greek yogurt, or your favorite toppings.
Notes
Ingredient Substitutions
Rolled oats are the best choice because they maintain their texture during baking, but quick oats can be substituted if you prefer a softer consistency. Substitute gluten-free rolled oats to make the recipe gluten-free.
Honeycrisp, Gala, Fuji, Pink Lady, Granny Smith, or Braeburn all work well as apple varieties to be used in this recipe. Or, swap in diced pears for a different fall flavor.
Replace almond milk with whole milk, 2% milk, Oat milk, Soy milk, or Coconut milk.
Honey, Brown sugar, and coconut sugar can be used in place of maple syrup.
If you’re not a fan of pecans, walnuts, sliced almonds, or even sunflower seeds provide great texture. Or simply leave the nuts out for a nut-free breakfast.

Chef Tips
Choose firm apples that hold their shape during baking, such as Honeycrisp, Fuji, Gala, Pink Lady, or Granny Smith.
Dice the apples into evenly sized pieces so they cook uniformly.
Toast the pecans before folding them into the batter to deepen their flavor.
Don’t overmix the oatmeal mixture or it can become dense.
For crisp, caramelized edges, bake in a ceramic or glass baking dish.
Let the baked oatmeal rest for 10 minutes before slicing for cleaner portions.
Add extra cinnamon sugar on top before baking for a lightly caramelized crust.
If you’re serving this for guests, reserve a handful of diced apples and chopped pecans to scatter over the top just before baking.Finish the casserole with a light sprinkle of coarse cinnamon sugar. The apples stay slightly firmer, the pecans toast beautifully, and the golden top gives the finished dish a bakery-quality appearance.Serving SuggestionsFor holiday brunches, create a breakfast board featuring slices of baked oatmeal, bowls of Greek yogurt, maple syrup, toasted nuts, fresh berries, apple butter, whipped cream, and warm cinnamon apples.
