Wake up to the cozy flavors of this baked oatmeal recipe with apples, raisins, and a nutty crunch—basically fall in a breakfast dish!
Baked oatmeal is a traditional and comforting breakfast casserole. Unlike regular oatmeal, which is made on the stovetop and has a porridge-like consistency, or overnight oats, this baked oatmeal recipe is made in the oven and has a consistency similar to bread pudding. There are endless variations, like blueberry baked oatmeal and morning glory baked oatmeal, but this version with tart apples, plump raisins, and a crunchy nut topping is a classic. Bonus: it can be made ahead of time and reheats beautifully.
“I’ve been making this dish for the last two years and it has been a staple for our family! When peaches are in season, I sub them for the apple and add nutmeg and ground ginger.”
What You’ll Need To Make Baked Oatmeal
- Light brown sugar – Adds sweetness and a hint of molasses, which pairs nicely with the fruit.
- Chopped walnuts or pecans – For crunch and nutty flavor; I like to divide them, mixing some into the oatmeal and sprinkling the rest on top for extra texture.
- Raisins – These add little pockets of sweetness and chew throughout the oatmeal. Feel free to omit them if you’re not a fan.
- Baking powder – Helps the oatmeal puff up slightly as it bakes.
- Cinnamon – Warm and spicy, it’s the perfect complement to the apples and oats.
- Salt – Balances the sweetness and enhances all the other flavors.
- Eggs – Bind the ingredients together and give the oatmeal structure.
- Milk – Keeps the oatmeal moist and creamy as it bakes.
- Vanilla extract – Adds warmth and depth of flavor.
- Unsalted butter – For richness and flavor, both in the oatmeal and to grease the dish.
- Apples – Add juicy bursts of flavor that contrast nicely with the warm spices and rich oats. For the best results, use tart yet sweet baking varietals, like Honey Crisp or Gala, which hold their shape when baked.

Step-by-Step Instructions
Begin by combining the oats, half of the nuts, raisins, brown sugar, baking powder, salt and cinnamon in a bowl.
Stir to combine.
In a separate bowl, make the custard by whisking together the eggs, milk, and vanilla.
Combine the custard with oat mixture and melted butter.
Arrange the chopped apples in a baking dish.
Top with the oat mixture and sprinkle remaining nuts over top.
Bake for about 40 minutes, until the oats are set and the top is golden. Be sure to save some leftovers; this dish is just as delicious cold out of the refrigerator the next day.

I’ve made this at least a dozen times and I just have to comment again that it’s SO tasty! Everyone who tastes this loves it. I do think you can reduce the sugar to 1/2 a cup and it’s still sweet enough to feel like a treat. The first time I made this my husband thanked me for giving him dessert for breakfast. I went through a phase where I used three apples rather than two because I wanted it more “appley”. Going back to two cups because I think it’s the best balance of ingredients. Also I love walnuts but for this dish pecans are just perfect. This is amazing with vanilla or plain yogurt scooped on top.
Do you have the peel the apples or will it work with the skin on?
Hi Carol, I prefer them peeled, but it’s fine to leave them unpeeled if you’d like. Enjoy!
I made this twice. Once exactly by the recipe and once using cranberries and walnuts. Both were are huge hit……definitely a keeper! Thanks!
This is delicious!!! I have been making it for a few years now and decided to get on here and leave a review. It comes together quickly, even quicker if you get the dry ingredients together the night before, the house smells wonderful as it cooks and it is always a hit.
This is truly a PHENOMENAL recipe. It is so easy and quick! I use more walnuts on top and also add dried cherries to the mix. I made this with unsweetened almond milk with regular milk and it came out just a good! I’ve also added extra fruit like blueberries which comes out nice. Love it!
Just like banana bread is your solution for old bananas, this is the recipe I make when I have extra apples. I’ve tried multiple variations with different nut combination, but I find as written the best. I’ll often bake the night before and steal a small amount with ice cream (its delicious) and then reheat for breakfasts throughout the week.
Made this one for my family and the all loved it! It’s super easy to make but so delicious!
This is a truly delicious oatmeal, it was the first baked oatmeal recipe I ever tried and remains the best. The fresh apple is the key ingredient for me instead of adding just dried fruit.
Once Upon a Chef is always the first place I look for new recipes. Many of them have become regulars on our menu plan. This oatmeal recipe is probably the one that I make the most often. I could see that it could be changed up in various ways, but it’s perfect the way it is so I don’t mess with it. It’s quick, easy, economical and my family loves it. What’s not to like?!
I love your blog. Every single recipe I have tried so far, turned out to be outstanding — including your Amish-Style Baked Oatmeal with Apples, Raisins and Walnuts. It’s a perfect combination of oats, fruits and nuts. It’s one of our favorites. In fact, we’ve had it for dessert, served with ice cream. Yes, it was INCREDIBLE!!!! 😊
