Because I never want you to get tired of it…  delicious breakfast, dinner, dessert. This is one I enjoy all day long!

Tips to Making Baked Oatmeal

  • This is easy to make ahead. Just follow the recipe to prepare the oatmeal and instead of baking it, cover it and place in the fridge overnight. Just pull it out the next morning and bake as directed. You might need to add a little extra time, but just keep an eye on it and when it’s set, pull it out.

  • You can also freeze baked oatmeal. I’ve frozen it before baking and after. I almost prefer freezing it after baking because then I can cut it into portion sizes or bite-size pieces. I just wrap each portion in plastic wrap and then place them all in a freezer bag. I pull one out at a time and let it thaw in the refrigerator overnight before I eat it.
  • Baked Oatmeal is best eaten warm with a little milk poured over it. The first time you try this it will seem weird, but just mash it all up with your spoon and it tastes amazing.
  • You can also add chopped nuts or raisins to this recipe if you want additional toppings.
  • I always use rolled oats for this recipe instead of quick oats.
  • You can actually bake this in whatever size dish you want. If you prefer a thicker slice, just bake in a 9×9 square and keep an eye on it while it’s baking, and take it out once it’s set. Sometimes I split the batter between two small pans so we can enjoy one immediately and freeze one for later.
  • This recipe is really easy to double or even halve depending on how many people you’re making it for.

How to store Oatmeal Bakes?

If you want to store oatmeal bakes, then you should use a container that has a tight lid. This way, you won’t need to worry about spills. Also, you should avoid storing them at room temperature, since they may become soggy. Instead, you should keep them in the refrigerator.

What makes this Apple Cinnamon Baked Oatmeal so delicious?

I enjoy the way that this apple cinnamon-baked oatmeal turned out. It tastes much like oatmeal that is prepared as a hot cereal, but it’s thicker, creamier, hotter, and filled with an apple-cinnamon taste.

This delicious apple cinnamon flavor is like having dessert for breakfast – cozy and comforting.

It also works quite well throughout the year, and it’s one of our favorite recipes, particularly for entertaining guests. It’s the perfect comfort food that everyone enjoys.


In conclusion, this healthy apple cinnamon baked oatmeal is both filling and satisfying. It’s an easy and delicious breakfast recipe for busy morning that requires minimal effort, and the end result tastes like you’re eating a hearty breakfast. It is a perfect breakfast for the on-the-go person on the way to work.
