This recipe for baked oatmeal is so, so comforting.

Then, all you have to do is scoop a portion out, warm it up, and top it with your favorite nuts and fruits throughout the week.

Ingredients for the baked Oatmeal

How to Prepare Baked Oatmeal 

Making baked oatmeal is as easy as stirring all the ingredients together and popping them in the oven until golden brown. 

  • Combine the Ingredients: In a large bowl, whisk the milk, eggs, brown sugar, melted butter, vanilla extract, and baking powder together. Next, add in the oats and stir until well-combined. 
  • Butter a Baking Dish: Drag a stick of butter all over a baking dish until it’s well-coated. 
  • Bake the Oatmeal: Finally, pour the oat mixture into the oven and bake it at 375°F for about 30 minutes, or until the top turns a golden brown color and the oatmeal is fully-cooked. Scoop, serve, and enjoy with your favorite toppings!

Helpful Tips for the Best Baked Oatmeal

While this recipe is so easy a kid could pull it together, a few handy tips will help you knock it out of the park. 

  • Use quick oats if you like creamy. If you like a creamier, finer texture, quick oats are your best bet. 
  • Use rolled oats if you have more time and like more texture. If you like a bit more bite, use rolled oats instead. 
  • Opt for whole milk for maximum creaminess. While you can use your favorite non-dairy milk or a lower fat dairy milk, nothing compares to the texture whole milk brings to the table.

Storing, Freezing, & Reheating Best Practices

Baked oatmeal is the perfect make-ahead breakfast because it can be stored in the fridge or frozen for quick breakfasts on the fly. 

  • Storing: To keep baked oatmeal on hand for up to a week, store it in an airtight container in the fridge so it doesn’t dry out. 
  • Freezing: You have two options here: 1) freeze the entire baking dish covered with a lid or plastic wrap or 2) freeze the oatmeal in individual portions. To thaw, remove the dish(es) and place them in the fridge overnight. 
  • Reheating: The best way to reheat your baked oatmeal is in the microwave for a minute or two.

FAQ

Can you make baked oatmeal the night before?

Absolutely! You can whip up the oatmeal the night before and either bake it and reheat it or keep it raw and pop it in the oven (it will only need 15 minutes in the oven after sitting in the fridge overnight).

Can you make baked oatmeal for one?

Yes! If you have oven-safe ramekins (the same ones you’d use for French onion soup), pop a portion in and bake it for one.

How do you know when baked oatmeal is done?

You’ll know the baked oatmeal is done when the top is a slight shade of golden brown and the oatmeal looks completely set (no raw oats in sight).

What kind of milk can you use besides whole milk?

If you don’t like whole milk, use coconut milk, almond milk, or oat milk instead. The end result won’t be as creamy, but it’ll still be super tasty.

What level should the oven rack be at?

To prevent the top from burning too quickly, place the baking dish on the middle rack.
