This easy baked oatmeal is the best way to start your day! It's almost like eating a warm oatmeal cookie in a bowl. Naturally sweetened with honey or maple syrup and filled with fruit. This single serving breakfast is baked in one pan for easy cleanup.
Oats are always a wonderful choice for breakfast but this unique healthy baked oatmeal is perhaps my favorite way to enjoy eating them.
Baked oatmeal is a little like a breakfast casserole made with oats, milk, spices, egg, and often fruit. It's one of my favorite healthy oatmeal recipes.
Why I Love This Recipe
In this baked oatmeal recipe, a layer of fruit lines the bottom of a buttered oven-safe dish.
We love using blueberries, fresh or frozen but feel free to use your favorite fruits in this oatmeal recipe. Sliced bananas, sliced strawberries, and chopped apples are wonderful additions.
The fruit is topped with a blend of oats and spices. A mixture of milk, melted butter, vanilla, an egg, and a touch of maple syrup or honey is whisked together and drizzled over the top.
The oatmeal casserole bakes in the oven and can be enjoyed soon after. Enjoy the oats hot, served with milk, yogurt or cream, drizzled with additional honey or as is.

Ingredient Notes
See recipe box below for ingredient amounts and full recipe instructions.
- Oats: Use old-fashioned oats for best results.
- Cinnamon and salt: I love adding a little cinnamon to my baked oatmeal but feel free to experiment with different spices in your recipe.
- Milk: Any percentage of cow's milk or you can use almond, soy, or coconut milk instead.
- Butter: Use salted butter.
- Vanilla extract: For flavor.
- Egg: 1 large egg is all you need.
- Honey: This baked oatmeal is not a sweet breakfast. I like using only a small amount of honey because I will often add additional fruit or vanilla yogurt to the top. Be sure to sweeten it as you prefer. If you think you'd like your oatmeal to be a little sweeter, add additional sweetener.
- Fruit: Use blueberries or your favorite fruit. You can use fresh or frozen and thawed fruit.

Hi Connie, you can prep the dry ingredients and separately mix together the egg, milk, and vanilla. In the morning combine the ingredients and bake.
Dianne Perry says
Please note that the way you write your receipe, many pages with pictures, does not make it possible to print just a one page receipe. If you could separate the receipe out so it is printable would be nice. Many of us don't need step by step instructions nor pictures.
Joanie Zisk says
Hi Dianne, you can simply jump down to the recipe using the "Jump To Recipe" button on the top of every recipe page. From there, you can print the recipe without photos, notes, etc. by clicking on the "Print" button. I would certainly hope you would NOT print the entire recipe page. The information provided in the recipe POST is for folks who DO want step-by-step instructions and photos. Again, to print any of our recipes, simply scroll or tap the Jump To Recipe button to go straight to the recipe box at the bottom of every post and print from there.
Linda says
Heavenly! Just made a few tweaks for my dietary and taste needs. Used sugar free maple syrup instead of honey and did add a little more sugar substitute for sweetness. Definitely a keeper♡
Cathie says
I have made this many times! Delicious! I also added peaches with the blueberries.
LCD says
Have you tried this with egg replacer instead of the egg and did it work?
Joanie Zisk says
No, this recipe has not been tested with an egg replacer.
Joni says
Can you use steel cut oats? Would it alter the cooking time? Thanks
Joanie Zisk says
No, Steel cut oats are the texture of a grain like rice or barley, so they require much more cooking than rolled oats.
Socorro West says
Can egg whites be used instead of the whole egg?
Joanie Zisk says
Yes. Use 2 egg whites in place of 1 whole egg.
Anne says
Delicious! I also added sliced bananas. I would make this again!
KK says
do you think it would be okay to omit the egg? or will it drastically change the consistency?
Joanie Zisk says
I don't recommend leaving out the egg. The egg makes the oatmeal more like a custard and the texture would be very off if left out.
Pam says
So easy and delicious. Used mixed berries and pure maple syrup instead of honey.
