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. We love ours with a nice dollop of Greek vanilla yogurt.

Splash of milk This is our husband's favorite!
Yogurt Try adding some Greek or regular yogurt. We love topping ours 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 freshly grated nutmeg.

Keeping leftovers

Baked oatmeal stores 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, microwave for 30-40 seconds or until warm.

Kitchen questions

What is the difference between rolled oats and old-fashioned oats?

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.
