What is baked oatmeal?
Baked oatmeal or Amish-style oatmeal is a traditional oatmeal casserole. It uses many of the same ingredients as the stove-top version, but with the addition of eggs and a little baking powder to help bind it all together and rise a bit in the oven.
Additionally, Amish oatmeal can be prepared plain or with toppings such as fruit, maple syrup, or nuts. I love mine with a nice dollop of Greek vanilla yogurt.
Ingredients
Here is what you will need to prepare this baked blueberry oatmeal.

- Milk- Use your favorite milk such as whole, 1%, 2%, or non-dairy milk.
- Eggs- You will need 2 large eggs.
- Oats- Use old-fashioned oats or rolled oats. Avoid the quick cooking and instant varieties as they just won't cook up the same.
- Butter- Unsalted.
- Baking powder- To help it rise a bit in the oven.
- Salt- Brings the flavors together.
- Maple syrup and brown sugar to sweeten up the oatmeal. I like the contrast between the 2 different sweeteners.
- Vanilla extract- Adds a nice sweet note.
- Cinnamon- A little warm spice compliments the blueberries.
- Blueberries- Fresh or frozen blueberries or you can substitute another fruit here.

Equipment
You will need a 9" baking pan, a bowl, and something to stir it all together.
How to prepare Amish-style oatmeal
Start by preheating the oven to 350°F. Next, you will whisk together the milk and the eggs in a bowl. Lastly, add the remaining ingredients and stir until combined. Pour the batter into a greased 9-inch baking pan. Bake for 35-45 minutes until golden brown on top. Easy, breezy!
Expert Tip: Reserve a few blueberries to arrange on top of the batter right before placing it in the oven. This will help evenly distribute the fruit in the pan.
How to serve this Amish style oatmeal
Amish-style oatmeal can be served like a casserole warm right out of the oven or at room temperature. You can also serve it as is, without any toppings, or you can add your favorites for added texture and flavor. Here are some great ideas for you to try with your oatmeal.
- Splash of milk- This is my husband's favorite. He loves extra warmed milk in his oatmeal no matter how it's prepared.
- Yogurt- Try adding some Greek or regular yogurt. I love topping mine with a dollop of vanilla Greek yogurt. It feels and tastes like whipped cream but healthier.
- Sweetener- If you have a sweet tooth, you can add a drizzle of maple syrup or honey to the top.
- Nuts- try adding some pecans, walnuts, or almonds for added crunch.
- Fresh fruit- You can never have enough fruit!
- Spices- Add a dash of cinnamon, cloves or some freshly grated nutmeg.

Storage
Baked oatmeal stores very well. Pre-cut the oatmeal into squares and keep it in the refrigerator for up to 5 days (that's a whole workweek of ready-made oatmeal that can be taken on the go). Store them in a lidded container or wrap them individually. When ready to reheat, just toss in the microwave for 30-40 seconds until the desired temperature.
FAQ
Rolled oats, or old-fashioned oats, are oat groats that have gone through a steaming and flattening process. In contrast, quick oats, or instant oats, are rolled extra thin and milled for faster preparation. They are also pre-cooked, so they don't work as well in baking recipes.
Baked oats are a healthy breakfast option. Wholesome ingredients like rolled oats, healthy fats, naturally sweetened fruit, and calcium-rich milk make for a nutrition-packed meal whole grain meal.
