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.

This is a great recipe. I made it the night before and baked it the next morning. I did as suggested and used 1/3 cup of brown sugar. It smelled wonderful while baking. It makes a good, satisfying breakfast and we even ate it for dessert after Sunday dinner! Would be a great breakfast for overnight guests.
I made this for my daughter and her friends over the holiday break and they LOVED it! I added some seasonal dried cranberries and walnuts and everyone really enjoyed it.
I make this all the time and add different fruits. I’m allergic to walnuts so I have used pecans instead.
Hi. Can you double the recipe. If so what pan and how long do you cook ? Thanks!
Hi Lisa, you can definitely double this and bake it in a 9 x 13 dish. You may need to add just a few minutes to the baking time. Hope you enjoy!
I have been making this for years and it gets rave reviews every time! I change up the filling depending on time of the year, some of the favorites are pear and pecan, peach and pecan, and chocolate and cherry. I also substitute Splenda/Truvia brown sugar blend, for a lower sugar version. I highly recommend, you won’t regret it!
Yum! Breakfast, Lunch & Dinner. I have made this three times now and family have eaten it at all times of the day and night.
Easy and fun to make and forgiving if you don’t have the exact ingredients. I threw in a handful of fresh raspberries and blueberries last time I made it.
This was so yummy! I made some modifications to make this dish vegan and it was a hit!
I used 1/4C of Brown sugar as suggested by other reveiwers, used quick oats to bake faster took 20 mins instead, substituted almond milk for milk, used cranberries instead of raisins, made 2 flax eggs (2 tablespoons of flax meal and 6 tablespoons of water). I also sliced and apples and cut them into smaller prices and accidently measured 2 Tablesspoons of Cinnamon instead of 2 teaspoons and it was still good. This yeilded 10 servings for me because I put a few spoonfuls in 1 cup mason jars. To top it all off I tiny bit a Maple syrup to satisfy my sweet tooth.
This recipe will definitely be a household staple, so much flavor I’m getting ready to make another batch!!! Thanks so much for this delicious receipe!!!
This was so good! The flavor was perfect. The top was perfectly crunchy and I love the custard element. Yum! I will definitely be making this again, although I might leave out the raisens next time. I decided I don’t love them although ate them anyways 🙂 I should also add that I was in a hurry so I cooked it at 350 instead of 325 for about 40 minutes and it turned out great.
I made this recipe as is – it looked delicious and smelled delicious as it was baking. I found that it was too sweet for me so will dial back the sugar. I will also dial back the butter just a bit. Planning on making this for Christmas morning for those who will be staying overnight. This recipe will stay in my breakfast rotation.
This has become our family’s favorite weekend breakfast. It’s super easy and delicious. When I cook, I like to use ingredients that I have readily available, so I experiment a lot and I found that we liked dried cranberries substituted for the raisins. I’ve also used some home made prune plum sauce drizzled over top. I’m looking forward to trying other breakfast recipes from your collection.
