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.

Can I freeze this?
Yep!
Has anyone double the recipe?
Did you just double ingredients or did you have to adjust some
Hi Alicia, you can definitely double this and bake it in a 9 x 13 dish. You may need to add just a few minutes onto the baking time. Enjoy!
Could this be adapted for stove top? I dont want to heat my house withthe oven
Hi Bethy, Unfortunately, this would not work on the stove– I’m sorry!
I just tried this. I put it in a glass 8inch square pan. I cooked it for the 40 minutes but it was still pretty much soup, even around the edges. How long does it need to cook in this pan?
I ended up having to bump the temp up to 350 and bake it for another 25 minutes
Thanks for the follow-up Sonya– I hope it was worth the wait :)!
I haven’t made this yet, but plan to have it this weekend when we’ll have houseguests. What do you serve with it? Thanks!
Hi Kay, it would be delicious with a side of bacon and some yogurt (on the side or a dollop on top). Hope everyone enjoys!
Hi Sonya, I’m not sure why it would still be soupy after 40 minutes– are you sure you measured all the ingredients correctly? Also, while this typically takes 40 – 45 minutes in the oven, maybe you need to up your baking time to 50 – 55 minutes.
Thanks for the response. It did turn out tasting good. But I think I will need bump the temp up from the start and see if it helps. Yes I measured everything out like the recipe calls for
My guests and I love it! Made it 2 days in a row. A keeper!
Thank you for this recipe! We make it at least twice a week with various tweaks. I especially appreciate the easy-to-memorize proportions.
Hi Jenn, I have high cholesterol and despise traditional oatmeal but this dish sounds so good. Do you think I could use 2% milk and egg whites instead of whole milk and eggs and unsweetened applesauce for the butter?
Thank you for your help
Juliet
Hi Julie, Yes, I think you could get away with all those substitutions. This recipe is pretty forgiving. You will need to use something to grease the baking dish- cooking spray would work just fine if you can use that.
Thank you for answering me so quickly. I really appreciate your help.
How did it come out with those substitutions? I’m in the same boat I detest regular oatmeal but have high cholesterol?
This is a five star hit in my recipe book now. You were spot on when you said it was even better the next day, cold from the fridge.
Recipie tastes great but mine came out still pretty soggy and I overlooked it for a while. Also, it seemed like the eggs cooked and separated from the rest of the mixture? I cooked it in a glass baking dish would this be why? Thanks!
Natalie, the inside of the dish is supposed to be pretty soft, but a little crispy on top. Next time, if you feel like it needs to firm up more on the inside (but don’t want it too crisp on top) you could cover it with foil near the end of the baking time. I’m not sure why the eggs would have separated from the remainder of the mixture. (I don’t think baking it in glass would’ve made a difference.) Did you thoroughly combine it before baking?
The same thing happened to me, where the eggs curdled during baking. It wasn’t soggy, but the texture was not similar to bread pudding — it seemed more similar to apple crisp with a thick oat topping. I did mix everything thoroughly, but the oats/dry ingredients and custard didn’t really come together in the bowl. The flavors were good, so I’d like to try the dish again if there are suggestions for fixing the curdling issue.
This is a FANTASTIC recipe! The textures, the flavors, the baked aroma were a perfect mix. I used Almond milk in place of regular, dried blueberries instead of raisins and reduced the sugar by 1/3. Next time I’ll reduce the sugar even more as it was still a tad too sweet for me. Topped it off with a drizzle of cream before serving. My family scarfed it down. Definitely adding this recipe to my fabulous farmhouse breakfast menu for guests!
