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.

We used as a springboard for what was on hand and doubled it. Because cooking once to get 2 meals is a sanity saver! Had frozen pears, small handfuls of dried apricots and figs, plus a lone Cortland apple (the best baking apple in my opinion). Did 1/2 cup sugar. And a bag of pecans. The sweetness was just perfect.
Forgot to mention in my comments adding orange zest brings this to the next level!
Hi Jenn; what do you think about adding some cranberries to this? I have a half bag leftover. Thanks! Love your site.
Sure, Sue, I think that would be nice. Please LMK how it turns out if you try it!
Can this be made in individual servings- such as wide mouth canning jars or tartlet pans?
Hi Beth, Sure that should work (as long as you can put canning jars in the oven). Individual portions may not take as long to bake so keep a close eye on them. Hope you enjoy!
Is there a way to search comments? I want to see what changes others made with types of milk, fruit, frozen berries or not, sugar substitutes, and ways to eliminate – apples are already sweet. I do not drink cow’s milk and regularly make rice pudding with soy milk – so guess it would work here – but wondering if anyone tried dried buttermilk, soy, cow’s milk product, and how it was?
Hi Madeleine, unfortunately, there’s not a search function for the comments. You can use the find feature on your computer and type in a word that may take you to some comments that would be relevant to you. Regarding your questions: 1) I think a non-dairy milk would work here but wouldn’t recommend buttermilk. I haven’t tried this dish with anything but brown sugar, but I suspect the stevia/agave blend should work. I’d love to hear how it turns out! 2) If you want to use berries, I’d recommend this recipe instead (and frozen blueberries will work). 3) I haven’t tried this with a sugar substitute but I think it would work. Hope that helps!
You could try Lakanto Monkfruit golden as a sugar replacement. I thought it was great!!
I love love love this recipe! We live in NE Washington and it was 14 degrees this morning (it’s only mid November). Our winters are long and very cold and this baked oatmeal is our go to most mornings. It’s a perfect start to our day! I’ve taken a couple of liberties and used dried cranberries instead of raisins and sometimes add ground flax. Thank you!
Can this be prepared, baked, and frozen for the future?
Yep — see the bottom of the recipe for freezer-friendly instructions. Hope you enjoy!
I make this recipe weekly for breakfast. It’s easily my favorite thing about the morning. If I bake this in my Kitchenaid Countertop Oven, how long should I bake it?
Hi Lauren, so glad this starts your morning off on the right foot! I’ve never used a countertop oven so I can’t say for sure, but I would assume that the timing is probably similar.
Hi there! Can this be make without nuts? Also as opposed to using fresh apples could one used diced up dried apple rings?
Hi Darrin, You can just omit the nuts, but I wouldn’t recommend using the dried apples. Hope you enjoy if you make it!
Oh my gosh this was wonderful. I make several baked oatmeal this is so far the best.
I have made this recipe several times, and I love it! I noticed that several people mentioned that it is runny or takes a long time to cook–more than 40-45 minutes. This has not been my experience. I cook this recipe at 350-375 degrees. I have never cooked it at 325. I assumed that 350 was the correct temperature when I viewed the recipe, and I didn’t look. Living at high altitude, as I do, over 5k feet above sea level many times cooking takes longer. It cooks in 40-45 minutes.
Haven’t eaten it yet. Smells great but looks runny. I hope after it sits for a bit it’ll absorb the liquid. I’ll let you know
We love baked oatmeal at my house. Another similar recipe calls for a 400 degree oven. . This recipe at 325, was not nearly ready after 55 minutes. I raised it to 370 to completely cook. Great taste!
This is delicious. It reminds me of bread pudding. This is the best baked oatmeal recipe that I have ever tried. Thank you for sharing!
I always enjoy your recipes but this one needed tweaking for me. I used half the sugar called for. I didn’t care for the texture. I am going to try mixing all ingredients together and letting it sit in the refrigerator overnight and then baking it. I liked that the oatmeal had added protein.
This tastes amazing! I skipped the raisins and only added 20 grams of sugar. The rosted walnuts on top are my favourite part.
