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 with apples

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

baked oatmeal ingredients
  • 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.

  • Made this and we all loved it. I kept the peel on the apples for additional fiber and used low sugar dried cranberries.

    • Hi Susan, Yes, you can bake this in ramekins –I’d start checking for doneness at about 20 minutes. Enjoy!

  • I can’t wait to try this! When making ahead of time, could this be refrigerated BEFORE baking, or do you recommend baking it first and reheating it later?

    I use a Cuisinart air fryer toaster oven instead of a conventional oven (requires a lot of experimentation on cook times & temps!) and because it’s just me, I usually half or quarter recipes. I would love to try this full recipe split across maybe 3-4 small baking dishes.

    • Hi Giovana, it’s fine to refrigerate it for a bit before baking. Hope you enjoy!

  • Delicious! However, I thought it was too sweet so would reduce the brown sugar next time.

    • Hi SG, It won’t have quite as much texture, but it would work. Please LMK how it turns out if you try it!

  • Wow! Have been searching for a reliable, delicious baked oatmeal recipe for a while and have finally found one. Loved the additions of apples, raisins and nuts. Plan to double it next time and freeze smaller portions for the college-aged kids’ apartment freezes. Thank you!

  • This is truly to die for!!! I even left out the 4 tablespoons of butter, only using a small amount to grease the pan. It was still amazing. The eggs give it a slight custard-like texture, much better than my normal “go-to” baked oatmeal recipe. Rich and delicious, and still pretty healthy!

  • This was amazing! I followed the recipe to the letter, with the exception of adding a little extra vanilla and a 1/2 tsp of almond extract. You should try the almond extract it pushes the vanilla forward. This was so good, perfect texture! Almost kind of fluffy!
