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.

I love your site. Have not tried a recipe I didn’t like. Could you give me a substitute for the egg in this recipe? We have an egg allergy. Thanks so much
So glad you like the site! Two of the best substitutes I’ve heard about (I haven’t personally tried either of them) are a combination of water, oil, and baking powder, and carbonated water. Scroll down to the bottom of this article for more information about both. I would assume many recipes would also work with some kind of store-bought egg substitute. Hope that helps!
We also have an egg allergy and this recipe worked well with Bob’s Red Mill Egg Replacement.
I was wanting to start eating oatmeal for breakfast but never cared much for the gloppy texture of it. This recipe is the solution!
As others have mentioned, I reduced brown sugar to1/4 cup and substituted some agave nectar. I used oat milk and dried cranberries. Now I can actually have oatmeal for breakfast!
Sorry. I used almond milk, not oat milk. I baked more like 55min to 1 hour.
Thank you for this wonderful recipe. We enjoyed it this morning for breakfast and look forward to having some for dessert with vanilla ice cream.
I’ve been enjoying your recipes for a number of years now. You empower me with confidence every time! Thank you for your sharing your talent.
💗
Great recipe Jenn. We used to live near Lancaster PA and Sugarcreek OH, true Amish country. Your recipe is spot on and tastes just like the oatmeal they would serve on the breakfast buffets at the Amish restaurants. Thank you for sharing this wonderful recipe!
I made this today. This is what I’ve been looking for. I like to eat my breakfast on my commute to work. I wanted an oatmeal that stayed together. I’ve been looking at oatmeal bars, but that really wasn’t what I wanted. I found a couple of apples today that were soft and I almost threw them out. Then I searched a baked Apple oatmeal and came across your recipe. I made it this afternoon and it is the recipe I have been wanting. I left out the nuts (don’t like them). I kept everything else the same. Next time I probably won’t include the raisins, but it is a good basic recipe I can see making with peaches or blueberries too.
My family loves it. Super easy to make, great texture and it’s a nice change from the mundane ordinary oatmeal.
I love this recipe. Every time. Just as written or changed up. Always great! Thank you for the recipe.
LOVE THIS! With many food allergies/sensitivities, this recipe was so easy to make with simple substitutions and tastes wonderful! I love anything cranberry so I substituted 1 cup dried cranberries (I prefer Trader Joe’s brand as they are organic, more moist and plump than other brands). I increased the amount as I had to omit the nuts due to an allergy. With a milk sensitivity (No not the lactose) I substituted Oat Milk (or Oat Beverage as they are now required to label it as!) Came out perfectly!
I had to dump out a lot of liquid after minutes of baking. It was also too sweet for my taste buds, but still very delicious. Maybe 1 cup of milk next time and less sugar?
Hi Lisa, How many minutes did you bake it? (I think you forgot to mention that in your comment.) Also, did you make any adjustments to the recipe? Did you use either an 8 or 9-inch baking dish?
I made this for breakfast this morning. It was so delicious and comforting. I am trying to reduce my sugar intake so I used 2/4 cup Stevia instead of light brown sugar. I substituted the walnuts for pecans, used Granny Smith apples and dried cranberries. I served it with a dollop of yoghurt and sugar free maple syrup.
This is so annoying with these constant alerts to post a message when I’m simply trying to read the reviews. Not to mention the plethora of ads… I’m try to make it but so frustrating…. I’m posting and hopefully this will stop. Review possibly coming later.
I make this time and time again, it’s always a crowd pleaser! I love to make it to bring into work and share with my colleagues. We just warm it up in the microwave. I’ve made it with almond milk. I usual use half golden raisins half cranberries. I don’t usually add the apple or nuts they’re not out usually on hand in the pantry. I do like to add a splash of nutmeg and clove in the winter months.
