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 substitute almond or soy milk for dairy milk? Also would a stevia/agave blend liquid be a good substitute for brown sugar?
Yes Maria, I think either almond or soy milk would work. 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!
This was amazing!! I only used 1/3 cup of sugar, a little maple syrup, and the can (I know I’m a cheat… 🙂 ) of apple cinnamon apples I had on the shelf. That was a match made in heaven! Would this work with bananas?
So glad you liked it! And yes, the recipe is really flexible; you can use whatever fruit you have on hand.
I love this and make it almost every week now (on Sunday) and take it to work with me for breakfast. It is so easy. And I think it gets better as the week goes on.
I cut the sugar down a bit (but do top with a bit of maple syrup). I’ve tried increasing the eggs (or adding more egg whites) to increase the protein. (still working on this.). AND I’ve even made the dish up the night before (let it sit in the refrigerator overnight) and baked it in the morning. Delish.
Keep thinking I may try it with blueberries but every week I think of how tasty the apple / raisin combination is that I make it again.
Thanks so much – great recipe.
follow up – has anyone tried baking in muffin pans rather than a square dish? I really want a batch to be six servings and impossible to cut a square into six same-size servings. If anyone has tried this, let me know how it worked (and how long you baked it)! thanks.
Donna
I now bake this every week in a large muffin pan. . so I get 6 servings and have breakfast all week. Love this recipe.
How long did you bake? And did you add an extra egg?
Just made this for breakfast this morning. I used dried cranberries instead because I didn’t have any raisins on hand. It turned out great, absolutely delicious. My kids also loved it and they are pretty picky. Thanks for another great recipe.
This was great! So good I had it for breakfast and lunch… I substituted maple syrup because I was out of brown sugar and used 1/2 as much as was called for but it was still too sweet for me. I might try just 1/4th cup maple syrup next time. It might even be good without any sugar… Jenn?
P.S. I made it a day ahead and stuck it in the oven … on a school morning, too!
Glad you liked it! I don’t think it would cause any problems if you completely eliminated the sugar/maple syrup, but a touch of sweetness is nice.
This is a great recipe to have in your arsenal for those cold winter mornings. Tastes great and is easy to prepare and toss in the oven.
Enjoyed. Very satisfying. Hubby and I had a portion for breakfast with maple syrup drizzled on it. Satisfied us all day long. Prefer it right out of the oven. (Not warmed up) Thanks for breakfast!
Can this dish be prepared the night before and cooked the next morning?
Definitely!
This fall we went apple picking and over did it on the picking. Wanted something different for breakfast so tried the baked oatmeal…HOLY MOLY! YUMMMMM! My husband loves this recipe! Between October and now (New Years Day) I have since made this using raspberries, blueberries, bananas, cherries, cranberries, craisins and raisins together, cherries and because I had a small can of mandarin oranges one day, I tossed those in with a bit of coconut and flax seed. So far every fruit I have used has worked to perfection. Thumbs way up!!!!
can this be made the night before?
Sure Jeanett, this dish reheats well.
Can I omit the eggs?
Hi Desiree, The eggs help thicken the custard and bind the oats together. If you want to omit them, I would suggest substituting ground flax seeds with water, applesauce or mashed bananas. I’d love to hear how it turns out!
