I feel like people talk a lot about dinners and lunches when it comes to meal prep, but breakfast is often skipped. Which is crazy to me because it’s probably my favorite meal.

And recipes like this Apple Cinnamon Baked Oatmeal are the reason why! It honestly tastes like you’re eating a warm oatmeal cookie except this one passes as a meal.

I’ve already shared my classic baked oatmeal with you, but now I want to show you how you can switch up your flavors to come up with brand new dishes, so you never get tired of baked oatmeal.

Because I never want you to get tired of it… 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. 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.
  • 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 to halve depending on how many people you’re making it for.
