Baked Apple Oatmeal is hearty, healthy, and full of warm apple cinnamon flavor.
We love having ready-to-eat breakfasts in this household. Not only is this baked apple oatmeal a ready-to-eat breakfast, but it is healthy and delicious too.
The flavor is reminiscent of apple pie, which pairs perfectly with the oats. The baked oatmeal, as well as my Banana Bread Baked Oatmeal, can be pre-cut into squares, and frozen, for easy breakfasts. Warm the slices and top with maple syrup for a delicious, nutritious bite!

Ingredients
- Rolled Old-Fashioned Oats - Old-fashioned oats are the oat of choice for this recipe.
- Milk - While the milk of choice can vary, milk is important to the structure and texture of this baked oatmeal custard.

- Light Brown Sugar - In addition, the natural sweetness of the apples, light brown sugar is the only sweetener in this recipe.

Recipe Tips and Ingredient Substitutions
- My favorite milk to use with oats is oat milk. Naturally, the flavors from the milk work beautifully with the oats. Whole or almond milk works great in this recipe too.

- The nuts are optional. Chopped walnuts or pecans work lovely with the other ingredients.
