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 made this before reading the reviews; my sister lives in Lancaster, PA, and Amish oatmeal is available at all the local markets and stores. Loving it when I ate it there, I tried Jen’s recipe–excellent! Of course, I now know after reading the reviews that I could cut down on the sugar with no ill-effect–as well as substitute different fruits as well. I followed the recipe exactly and my son and I (my husband isn’t an oatmeal guy) ate it all week for breakfast. Easy to just scoop out a portion, nuke it, and you have instant, excellent breakfast!
This is a huge kid favorite! I tend to make it with apples and cranberries as I like the tang that comes from the cranberries. I lower the amount of sugar quite a bit and it is still very tasty!
I double this recipe for a 9×13 pan and make it twice a month. It is my husband’s favorite breakfast and often requests it. I like to take it out slightly before it is set to give it a custard texture and flavor. I love to eat it cold with some milk as it reminds me a little bit of rice pudding. This is a winner in our family!
A breakfast mainstay! Everyone loves this dish which says a lot given my kids usually groan when oatmeal is part of anything. I cut down on the brown sugar from 3/4 cup to 1/2 cup for a less sweet version and no one is the wiser!
I’ve made this baked oatmeal for breakfast so many times and it is always a BIG hit. To save time in the morning, I put everything together at night so all I have to do in the morning is preheat the oven and bake it. Super easy and so yummy!!!
Made this with oatmilk instead of milk and it was yummy
I have made this recipe many times and recommended it to others many times. Sometime we use apples, sometime it is blueberries omitting the raisins. It is delicious whatever fruit is used. It works fine to also freeze it before baking, then bake from the frozen state. I put it in a freezer to oven dish wrapped tightly in foil. I add a few minutes to the baking time.
I first made this on a cold Illinois winter morning, thinking it would be just what I needed to warm up and get energized for my day. It was perfect! Delicious and easy to make, it was good hot or cold and reheated very well! This is on winter rotation for me and mine. Highly recommend!
Love this recipe as well as your baked oatmeal with blueberries. Going to make it this afternoon! Going to try per other suggestions less sugar.
You are now my “go to “ source for delicious ways to prepare food!! Grateful thatyou share your expertise with us.
This is one of our very favorite breakfast recipes. I usually put it together the night before and bake in the morning.
