    Baked Oatmeal Casserole

    Oatmeal is definitely a classic breakfast dish many of us are very familiar with. As plain as oatmeal can be, I love it- when you have a thing of quick oats on hand, few other breakfast options are as fast and filling. Recently, though, I came upon a recipe that- while not as fast- is certainly just as easy as tossing those quick oats into the microwave. It’s as simple as mixing your ingredients and tossing them into a baking dish: that’s right oatmeal breakfast casserole!

    This easy oatmeal bake recipe is especially heart and filling, seeing as it’s packed with oats. It even remedies some of the problems of plain oatmeal- a bit of added vanilla, cinnamon, and nutmeg adds a welcome touch of flavor! The best part of this Amish baked oatmeal is that you can easily prep it the night before. It also keeps really well in the fridge, meaning you can enjoy it for breakfast for quite a few days!

    Ingredients for Oatmeal Bake

    • Oatmeal – For this recipe, we used quick oats. We haven’t tried it with any old-fashioned or steel-cut oats- it may have to bake a little longer if you use those. Try it out and let us know how it turned out for you!
    • Eggs
    • Milk
    • Butter, melted
    • Baking Powder
    • Brown Sugar
    • Vanilla Extract
    • Cinnamon
    • Nutmeg
    • Salt

    Ingredients for Baked Oatmeal Casserole

    How to make Amish Baked Oatmeal

    After greasing an 8×8 baking dish and getting our warmed up to 350 degrees, we can properly get started on this recipe. First, crack your eggs into a mixing bowl and give them a quick mixing until they’re well-beaten.

    Eggs with whisk in a bowl

    After getting those eggs beat, add in your milk. Once again, mix well to combine.

    Milk added to eggs

    Here, we’re going to add almost all of our other ingredients. Add to the egg and milk mixture your vanilla, brown sugar, baking powder, cinnamon, nutmeg, salt, and melted butter. Again, mix this all well until the resulting mixture is consistent.

    Spices added to egg mixture

    To this mixture, we’re finally going to add our oats. Toss them in with the mix and give them a thorough mixing.

    That’s out casserole filling all mixed up! Now we can focus on getting it baked. Transfer your oatmeal mixture over to your greased baking dish and pop it into the oven.

    Let that bake for a little while. Like we mentioned above, we used quick oats for our casserole and it ended up needing about 30-40 minutes. If you used something like old-fashioned or steel-cut, you’ll likely need to let it go for a bit longer. It’s done when it’s all set and there’s no real “jiggle” left to it. After it’s finished baking, let cool for a few minutes before slicing and serving. Feel free to top your plate with your favorite oatmeal toppings. Consider some nice, fresh fruit like some apples or blueberries or a drizzle of your favorite sweetener like honey. Whatever you top it with, enjoy!

    Make-Ahead/Storage Tips

    • Considering this is a breakfast recipe, you’ll likely want to enjoy it in the morning. To keep this low-effort, prep your casserole the night before you plan on enjoying it- wrap over it tightly with plastic wrap to keep it fresh. The following morning, get the oven warmed up and then toss your casserole in to bake. Should be ready in time for a nice family breakfast!
    • After you’ve baked your casserole, you should be able to keep it or any leftovers in the fridge for a few days. Just follow good storage protocol- keep covered in the fridge, uncover only to grab a portion, then re-cover tightly. This should warm up easily enough in the microwave! Makes for a nice, easy breakfast.

      While looking for a plain baked oatmeal recipe I came across yours. I chose it based on the photo and then read the recipe and found it to be just what i was looking for. I made this with regular rolled oats and it turned out great! Soooo delicious!

      This is also very good if apples, cranberries, or both are baked right into the oatmeal. Yum!
      Also Splenda or Truvia can be used as sweetener for those who can’t have sugar. Enjoy❤️

      Thank you thank you thank you I have been looking for this recipe for a very long time I have a friend from Pennsylvania and she would never give me the recipe. I’m looking forward to making this for the weekend or maybe right now. The only thing I changed in the recipe is I added a little Maine maple syrup on top👏😊

        Hi Nancy! It’s one of those keeper recipes. My mom made it for Christmas breakfast almost every year. It’s perfect for feeding everyone oatmeal without all the individual bowls. I recall her adding fruit occasionally but I always preferred it plain with lots of maple syrup too. I hope you enjoy it.
