One of my favorite go-to meals for breakfast, and sometimes dinners, is cranberry oatmeal which is filled with sweet apples and cinnamon. I even have a special bowl just for my oatmeal which I think may make me an oatmeal snob! If you are like me, you don't always have time to make a bowl of oatmeal in the morning but still want all those flavors, that is why this oven-baked oatmeal is one of my go-to recipes.
What is baked oatmeal?
- Baked oatmeal is more like a casserole or even a cake than a creamy bowl of cooked oats. It has texture to it, and the addition of applesauce, eggs, sugar, and milk binds all the oatmeal and plumps it up for a hearty slice.
- When done, cut the oatmeal into slices and serve warm from the oven. You can top the slice with whatever you like, maybe a dollop of yogurt, fresh fruit, maple syrup, or even lemon curd.
🤍Why this recipe is amazing...
- One bowl and a casserole dish are all you need for this recipe, plus simple pantry ingredients.
- Fifteen minutes of prep time and 30 minutes of baking time are all you need for this warm-from-the-oven breakfast.
- This recipe is very adaptable for oatmeal lovers, and you can make it all year long by changing flavors throughout the seasons. Add warming spices in the winter, or maybe use a vanilla bean in the summer. Make baked oatmeal with fruit, berries, and nuts, or keep it simple.
- Baked oatmeal for breakfast is easy when you bake the casserole the night before and reheat it in the morning, which is great for busy families. I like to cut this into slices once cooled and put it in the fridge, and then everyone can pull out a slice and reheat it themselves. Make-ahead recipes are a lifesaver.
- This is a great recipe to serve during the holidays. Just bake the oatmeal the night before, get up in the morning and reheat it. No spending hours in the kitchen when your company is around.
- Need more than 8 servings, just double the recipe and bake in a 13" x 9" pan.
🧾Baked Oatmeal Ingredients
This oatmeal contains all the ingredients I would put in my bowl of creamy oatmeal: oatmeal, apples, brown sugar, cranberries, pecans, cinnamon, and milk. To add structure and bind the ingredients add an egg, butter, and baking powder.
🍎Why use applesauce in this recipe
Instead of just adding apple chunks use applesauce for moisture to help plump up the oatmeal. You can use jarred applesauce but if you don't have any just cut up an apple and add some apple juice or orange juice and cook the apple until tender, and puree or mash it up.
🥣How To Make Baked Oatmeal: Step-By-Step
- Heat your oven to 375 degrees F. and you will need an 8" x 8" casserole dish.
- Step 1. In a large bowl mix the oatmeal, brown sugar, and baking powder.
- Step 2. In a medium-sized bowl melt the butter then add the applesauce, milk, and egg. Using a whisk mix all the ingredients together then pour into the oatmeal bowl and mix until thoroughly combined.
- Step 3. Mix in the dried cranberries and chopped pecans.
- Step 4. Pour this mixture into the casserole dish. Bake for 30 minutes until golden brown and set.
- Remove the casserole dish from the oven and let cool for about 10 minutes, cut into squares and serve warm with a drizzle of maple syrup.
- Cover leftovers and set them in the refrigerator for up to three days.
- To reheat leftovers, microwave on 50% power for about 40 seconds or until warm. You can also wrap the oatmeal square in foil and heat it in the oven at 350 degrees F. for 20 minutes.
Cut the warm apple and cinnamon-baked oatmeal into squares.
And for some extra goodness, pour some pure maple syrup on top and ENJOY!

To be honest, before I made this recipe, I had never heard of baked oatmeal until I went to my favorite bakery in Santa Rosa, CA, called Criminal Baking Co. and Noshery. In their case of beautiful pastries, they had slices of baked oatmeal. What? Baked oatmeal? Never had it, but it looked like a piece of cake, so obviously, I was all in. But after some serious interrogation, I learned the secret to their baked oatmeal, and ordered a slice, warmed up and served with lemon curd, it was so goooood!
If you are ever in Santa Rosa, make sure you visit Criminal Baking. It's off the beaten path, down a little side street, seats about 12, and serves some amazing pastries.
