Baked Apple Oatmeal with Cinnamon and Maple Syrup

This Amish-style baked oatmeal with apple and cinnamon makes an easy, delicious breakfast—perfect for making ahead.

Oatmeal was a regular breakfast at my house growing up, but it was usually the quick packet kind. In the last few years I’ve discovered how much better oatmeal can be when made from scratch. This Amish-style baked apple cinnamon oatmeal is simple to prepare, hearty, and ideal for school mornings or meal prep. It fills the kitchen with warm autumn aromas and keeps well for busy weeks.

This recipe is easy to adapt, reheats well, and is great for anyone who prefers a make-ahead breakfast.

Apple Cinnamon Baked Oatmeal

With cooler weather and the start of school, I crave cozy flavors like apple and cinnamon. Baking the oats gives this dish a pleasant structure—less mushy than stove-top or microwave oatmeal—and creates a satisfying texture that works for breakfast or even dessert if you’re feeling indulgent.

This casserole can be assembled the night before and baked in the morning, or baked ahead and reheated. Either way, it helps make mornings less stressful. Serve warm in squares, topped with a drizzle of maple syrup, a scoop of yogurt, or extra fresh fruit.

What is Amish Baked Oatmeal?

Baking creates a firm, slightly custardy texture that slices neatly—perfect for packing in lunches or reheating for a quick breakfast. Because it stores well in the refrigerator, it’s an excellent choice for anyone who wants a hassle-free morning meal.

Notes

This recipe uses quick oats. If you substitute rolled oats, you may need more milk and a slightly longer bake time for best texture.

Other Flavors

If you prefer something other than apple, this baked oatmeal works well with many fruits—blueberries, cranberries, or sliced peaches all make great variations. You can also add nuts, shredded coconut, or a handful of chocolate chips for a different twist.

Serve slices warm on their own or with toppings like fresh fruit, maple syrup, yogurt, or a sprinkle of brown sugar. It’s a versatile, make-ahead breakfast that adapts to whatever you have on hand.
