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.

  • Absolutely loved this dish as did my husband and friends I shared it with. All of your recipes have been perfect and delicious. I recommend your site, recipes, and cookbook to everyone! The only substitutions I made was using 50% Less Sugar Craisins instead of raisins, and pecans instead of walnuts because that’s what I had on hand. It makes for fabulous leftovers either cold or warmed up.

  • Thank you, Jenn. So many of your dishes have become staples in my kitchen. I have been an ardent Ina follower for years, and your recipies are the first I’ve come across that compare in quality and accuracy. I love this one. I made it exactly as written first, which is great. On subsequent bakes, I cut the sugar to 1/4 cup, and cut the butter in half, only in an attempt to reduce calories. Also great. I must say, this is even good cold for some reason and keeps for several days in the fridge.

  • Hi Jenn,
    It’s another rainy day in So Cal. and decided I had to try this recipe and I’m so glad I did! I read through many of the comments and made slight adjustments to sugar (reduced to 1/2 cup) and added an additional tsp. of vanilla. My husband and I loved it and look forward to the leftovers. Thank you again for the recipe, you are the absolute best.

  • Love this recipe! I’ve tried several different oatmeal bakes, and this is a favorite! As a nutritionist, I’m always on the lookout for nutritious and delicious options. This is definitely a winner :-). My only adjustment was to reduce the sugar to 1/2 cup – and I used coconut sugar. It was delish and still plenty sweet.

  • I made this with steel cut oatmeal and lowered the sugar to about 1/4 cup. It is amazing! I can’t stop eating it.

  • We love this oatmeal! Our favourite variation is to substitute dried apple for the fresh apple, because it intensifies the flavour without adding more moisture. We also like to add fresh or frozen raspberries in lieu of the raisins.
