Apple Cinnamon Baked Oatmeal is a healthy meal prep breakfast that is made with whole ingredients and only takes 30 minutes!

I enjoy oatmeal all year long but as soon as autumn weather gets here, I am ready for my oatmeal to be baked. I love a warm breakfast on chilly mornings. I adore the smell of cinnamon and apples baking in the oven. And life is usually getting busier which means I need an easy meal prep breakfast that is also healthy and satisfying.
This Apple Cinnamon Baked Oatmeal fits the bill! This hearty breakfast can be made on Sunday and last all week until Friday. It is full of seasonal goodies such as apples and almonds, and it is packed with delicious oats to keep me full of energy all morning!

Apple Cinnamon Baked Oatmeal Ingredients
Oatmeal is an easy and healthy breakfast to start your day with! Baked oatmeal makes breakfast even easier to manage when you are running low on time. Below are the ingredients you will need to make this recipe and some substitutes.
- Quick Oats – These cook faster and with less liquid than other oats. If you are going to substitute with rolled oats, old-fashioned oats, or steel-cut oats, you will need to increase your liquid, cooking time, and possibly eggs.
- Apples – use your favorite apple or whatever fruit or vegetable that is in season and on sale. Good apple picks are fuji, golden delicious, granny smith, or Honeycrisp. Good substitutions are pears, blueberries, pumpkin, and zucchini. If you are substituting with stone fruit (such as pears), pre-bake fruit for 10-20 minutes, or until soft, before adding dry and wet ingredients.
- Almonds – these can be substituted for other nuts such as; peanuts, walnuts, pecans, or anything you would like. You can roast the nuts ahead of time for about 10 minutes, until fragrant, for even more flavor.
- Honey – can be swapped for maple syrup, molasses, agave nectar, or brown sugar
- Egg – I am not sure if a flax egg or just egg whites would work as a substitute. If you try it out, leave a comment and let us know!
- Milk – I used almond milk but any milk will work! If your milk is sweetened, you might want to use less honey in the recipe.
- Cinnamon
- Salt
- Baking Powder
- Vanilla Extract
- Topping – Yogurt

How to make Meal Prep Baked Oatmeal
Start by chopping your apples into about 1-inch cubes. You don’t want them too big or they won’t cook all the way through while the oatmeal is baking. Toss the apples into a greased 8×8 baking dish and coat them with a little bit of cinnamon. Then move on to mixing together the dry ingredients in a bowl and sprinkling it over the apples. Next, mix together the wet ingredients and pour it into the baking dish too. Lightly mix everything in the baking dish together, incorporating all of the ingredients and getting rid of any air pockets. Then bake it!
Once your oatmeal has set and reached a perfectly golden brown top, remove it from the oven and let it cool on the counter. Before storing your oatmeal away in the refrigerator, allow it to cool completely to room temperature. This will help your oatmeal to stay fresh for up to 6 days in the fridge!
Your oatmeal will be ready to eat whenever you are! Some of my favorite ways to enjoy baked oatmeal are:
- warmed up and peanut butter drizzled over the top
- cold with yogurt + warm peanut butter on top
- warmed up with milk poured over
