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.

Delicious breakfast on a cold wintery day. Cut down the sugar a bit as I am trying to minimize sugar intake.. Still totally delicious
This is so delicious – the whole family had it for breakfast this morning. This time, I prepped all the ingredients (except apples) the night before, but didn’t combine them until just before putting it in the oven. The last time I made it, i prepared it the night before so the oatmeal soaked in the milk mixture. I prefer the texture when it doesn’t sit combined overnight. The texture from today’s dish was perfect! Thank you for recipes that make me look like a chef!
This was great!!! Nutritional and tasty!
This is the best breakfast dish ever. Tastes like apple pie for breakfast. It is economical because it feeds a lot of people. Uses ingredients I typically have on hand. Quick to throw together So delicious! And leftovers are convenient to heat & eat the next few days. I’ve even prepped it the night before and refrigerated it then baked the next morning. It still turned out great, although I prefer the texture when it is baked right away. It is great for pot lucks because I can make it ahead and serve at any temperature. I always get asked for the recipe.
Can almond milk be used in place of milk?
Sure, Ann, that should be fine. Enjoy! 🙂
This recipe is a new favorite of mine. I bake it Sunday and then eat it for breakfast throughout the week. Just pop a serving into the microwave for 45 seconds, drizzle a tiny bit of maple syrup over it (as a previous review suggested), and I’m good to go! I made a few adjustments for my own personal preference. I reduced the sugar to 1/3cup, and don’t add any butter or oil. I melted the butter and forgot it in the microwave by accident the second time I made it and didn’t miss it. And I sprinkle 1/2 cup of pecans on top and leave out the walnuts. It’s delicious the way Jenn has written it though (as are all of her recipes that I’ve made)! These are just my own personal tweaks.
Can I use oil instead of the butter?
Sure, Seal, that should work. Hope you enjoy!
Made this for breakfast and it is great! Not too sweet and packs hearty goodness via the steel cut oats, walnuts, apples, raisins, etc. I put a dash of half and half on my serving. Mmmm.
My husband suggested serving it with pork tenderloin tomorrow (just for us) and I think we’ll try it! I love a double-duty entree!
Cooked this morning for Thanksgiving brunch and it is wonderful! And true to what was written the longer it sits the better it gets. Ingredients were what I already had and my 13 grandson loved it♥️
Hi Jenn,
I was thinking of making this for the staff at my work and was thinking about making a variety of flavors. What do you think of pears & pecans and apples & fresh cranberries and walnuts? I also have mangoes but not sure what would work best with them. I would love your advice.
Thanks!
Hi Karen, one of the things I love about this recipe is that it can be tweaked to use a variety of fruits and nuts. I think pears and pecans and apples and cranberries sound delicious! Mangoes sound a little less conventional but I think you could certainly get away with it. Please LMK how the different varieties turn out!
Yum! I have tried and enjoyed many of your recipes, and this was no exception. The texture and flavor was great. I like how the walnuts on top got a roasted flavor. I do agree with some other posters though that it was a little sweet, so next time, I might reduce the sugar. Probably just a personal preference though!
Has anyone tried this with instant oats?
Hi Nally, the texture will be a bit mushy, but instant oatmeal will work in a pinch. Hope you enjoy!
