Why This Is a Family Favorite
This apple cinnamon baked oatmeal recipe bakes up soft while still holding together well. The eggs give it structure, and the applesauce keeps it moist without needing much sugar. The butter and brown sugar on top create a lightly caramelized finish that makes it feel special without being fussy. Once cooled slightly, it serves beautifully and reheats well for leftovers.

Ingredients
This apple cinnamon baked oatmeal recipe relies on ingredients I almost always have on hand. Each one plays a simple role in creating a filling, comforting breakfast that holds together well and reheats beautifully.
- Rolled oats for a hearty, nourishing base
- Applesauce for gentle sweetness and moisture
- Milk to help everything bake evenly
- Eggs to provide structure and protein
- Brown sugar for warmth and depth
- Vanilla to round out the flavor
- Butter on top for a golden, comforting finish

How to Make
Step 1: Preheat and Prepare the Pan
To make this, start by preheating the oven to 350 degrees. Grease an 8×11 baking dish well so the oatmeal releases easily after baking.
Step 2: Mix the Ingredients
In a large bowl, mix the rolled oats, applesauce, milk, cinnamon, salt, brown sugar, vanilla, and eggs until fully combined. Stir until everything is evenly distributed and no dry oats remain.

Step 3: Transfer to the Baking Dish
Pour the oatmeal mixture into the prepared pan. Spread it evenly so it bakes consistently from edge to center.
Step 4: Add the Topping
Place five to six small pats of butter across the top of the oatmeal. Sprinkle with additional brown sugar if you want a slightly sweeter, caramelized finish.

Step 5: Bake Until Set
Bake for 30 to 35 minutes. The center should be set and no longer wet when finished.

Step 6: Rest and Serve
Let the baked oatmeal rest for a few minutes before serving. This helps it firm up and hold together when serving.

Variations and Notes
Adding Fresh Apple
If you want more texture, you can finely chop one apple and stir it into the oatmeal before baking. This adds small bites of apple throughout the baked oatmeal and works especially well in the fall.
Swapping the Applesauce
This apple cinnamon baked oatmeal recipe is very forgiving and easy to adapt. You can swap the applesauce for another fruit sauce, such as peach, without changing the texture. Jam that did not set properly also works well and blends smoothly into the oats.
Reducing Food Waste
Using extra sauce or unset jam is one of my favorite ways to reduce food waste. This recipe is a simple way to use what you already have instead of throwing it away.
Using Water Glassed Eggs
During the winter months, I often use water glassed eggs if they are available. This helps preserve fresh eggs while still allowing me to make hearty, nourishing meals for my family.
Make Ahead
This apple cinnamon baked oatmeal recipe works beautifully as a make-ahead breakfast. Bake it the night before, cover it, and store it in the refrigerator. Reheat individual slices as needed for quick mornings. It is just as comforting the next day.
