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.

This is my favorite recipe for baked oatmeal! I cut the brown sugar to 1/2 cup for guests who want it less sweet and put maple syrup on the table for people who like a little more sweetness. Easy to make and so, so good!
Yikes – I think I forgot to hit the 5 stars before I posted my comment!
This oatmeal is amazing. A few years ago, I made nearly 50 batches and delivered to friends, neighbors, and family as holiday gifts, and nothing I’ve made since can live up to this. It has become my go-to when looking to help out a friend after a new baby, illness, etc because it is nutritious, comforting, and delicious.
I have to admit I cut the sugar down to 1/4 cup, and it has never been missed. I also sometimes mix in cranberries with the raisins. I do apologize for rating and altering the recipe at the same time, but I can safely say that this has become a cherished family recipe that I expect my kids will be making with their kids. If you knew how picky my son is, you’d understand what a compliment that really is!
I love your recipes, and appreciate that they are so easy to follow. Thank you for sharing!
Can I use dried apricots in place of raisins? I have some I need to use up. Do I need to make any adjustments to the recipe? I’m looking forward to making this dish! Thank you Jenn.

Hi Marianne, dried diced apricots are perfectly fine to use with no other adjustments. Hope you enjoy!
Thank you so very much for this recipe. I used 3/8 c. Splenda brown sugar (which is essentially 3 Tbls. brown sugar) and pecans in place of walnuts just because I love the taste of pecans. Of course I toasted my nuts! No matter which way I made it – with or without raisins and/or apples – it was DELICIOUS!!! Even warmed up on day 2, just as yummy. Great recipe.
Can I use water in place of milk and just increase the butter a little bit?
Yep 🙂
This is by far the worst recipe I have ever made. I followed it to the letter (except no walnuts). It was tasteless and soggy, I threw most of it away. Where is the flour? Why do use baking powder if there is nothing to rise? Two cups of milk? What a waste of good ingredients.
This is not a bar recipe. This is closer to a custard recipe. It’s supposed to be “soggy” just like bread pudding is supposed to be.
This dish is delicious. Not certain I would like it, I cut the recipe in half. That was a big mistake. Should have made the entire dish, it was that good. Based on some other comments I reduced the sugar, increased the vanilla and added a splash of almond flavor. I’m not sure the sugar needed to be reduced. It depends on how sweet you like your oatmeal. I used a honeycrisp apple and it was perfect. I highly recommend not leaving out the apples. I baked it at 350 degrees for 45 minutes and it came out perfect. I warmed it up the second day in the microwave and it was just as good. I now have an oatmeal dish my husband will eat. Add a scoop of vanilla ice cream and some caramel sauce and you’ll have an amazing dessert. I can’t wait to make this for my in-laws, they’ll love it.
Hi Jenn, I am not big on apples, do you think banana at bottom of dish would work? If yes, would I have to make any changes to compensate for no apple? Thanks in advance for your answer.
This recipe is pretty flexible, so you can get away with bananas here. I’d probably mix them in with everything though, instead of lining the bottom of the pan with them. Please LMK how it turns out!
I didn’t read the recipe all the way through and mixed the apples in and I didn’t add walnuts, I added 1 cup of raisins, couple Tlbls of wheat germ and some chia seeds. It was so amazing! It was even better warmed up the second morning! Loved it!
Always rapidly devoured, warm or cold, by our family. With picky little ones, I shred the apples (don’t have to peel!) and decrease the sugar to 1/4 cup. Once I forgot the and sprinkled it on top and that was good. Very forgiving/flexible recipe. Sometimes I’m too lazy to melt the butter and just skip it. I always bake it in an 11×7 inches (2 Qt, 1.9 L) pan and sometimes it takes a bit longer to bake (probably because of the extra liquid released by shredded apples).
