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.

Baked oatmeal? I wasn’t sure but I tried the recipe. The first time I made it I substituted dates for the raisins and added some fresh blueberries. Delicious. The subsequent times I made it, like many others, I decreased the sugar by half. I’ve made it with dried fruits like apricots and cherries but my family loves it best when I make it with fresh blueberries.
Just made this baked oatmeal yesterday for our family’s “Cookie Day.” Each year on the Ann of my mom’s death, my daughters, grandkids and I get together to make cookies using Mom’s handwritten recipes. We start early, so I make breakfast for everyone. This baked oatmeal was a hit with young and old! Both daughters promptly asked for the recipe.
Paula, my comment has little to do with the recipe itself…I just wanted to say that I think the way you honor your mother’s memory is lovely, and so meaningful!
The best and my new favorite go-to breakfast treat. Filling, delicious, full of textures, can be changed to add favorite fruits–just nothing wrong with this recipe. Made it for a large crowd for day after Thanksgiving. Everyone asked for more.
I really loved this oatmeal but I cut the sugar back to 1/4 cup and it was perfect.
This dish is delicious; however the prep time is not 10 minutes but more like 40. You’ll need at least 6 apples and it takes more time to peel and chop up than 2 apples. Bake time is more like 50 minutes unless you prefer hard apples.
I made this today for the first time. I make a lot of crockpot steel cut oatmeal and have learned that I like far less sugar than most recipes call for. Usually there is enough sugar from the fruit that I don’t miss it. So I cut the brown sugar back to 1/4 cup. I wasn’t paying attention to what I was doing and added baking soda by mistake. After googling it, I see that as long as there is an acid in the recipe, it isn’t a problem. So I was okay because the acid in milk. The other big change was that I left the butter out completely just to be healthier. I LOVE butter but I promise that this oatmeal is so good without it that you would never miss it!! Even without it, the oatmeal was creamy and delicious. I wanted the flavor of my favorIt’s oatmeal cookies, so added 1/4 tsp of nutmeg. I baked them up in a pan that you make hamburger buns in and it filled the 6 spaces perfectly to give individual servings that I can package for work. (Bake 25 mins). SO delicious And easy to make healthy changes.
Hi Jenn, Really love your recipes and as usual, can hardly wait to try this one! I am planning a special family breakfast and would like to bake in individual ramekins (~8 oz). What is your recommendation on adjusting the baking time?
So glad you like the recipes, Renae! I’ve never prepared these in ramekins, but I think they’ll be nice that way. I’d suggest checking them at about 20 minutes; just keep an eye on them!
How long should I keep leftovers in the fridge before freezing?
This should keep nicely in the fridge for about 5 days. Enjoy!
Baked as directed. Delicious with plain yogurt!
I haven’t made this yet and would like to try it. But I don’t like to eat a lot of sugar so not sure it’s a good recipe for me. The nutrition info you give says this dish has 46 grams of sugar. That’s a lot of sugar and I’m trying to figure out where all the sugar is from or is it a misprint?
Hi Linda, Thanks for catching that – it was a typo. The sugar is still relatively high though because of the brown sugar, raisins and apples. Feel free to reduce the brown sugar as necessary.
