6-Ingredient Amish Baked Oatmeal Casserole
This Amish-style baked oatmeal is a cozy, old-fashioned breakfast that’s simple, hearty, and perfect for busy mornings. Instead of cooking oats on the stove, you bake them in a custard mixture of milk and eggs. The result is a warm, lightly sweet oatmeal that can be scooped or cut into squares and reheats beautifully throughout the week.
Ingredients (Serves 6)
2 cups rolled oats (old-fashioned oats, uncooked)
2 cups milk
2 large eggs
⅓ cup brown sugar (or maple syrup)
2 tablespoons melted butter (or neutral oil)
1 teaspoon ground cinnamon
Optional additions:
1 teaspoon vanilla extract
Pinch of salt
½ cup raisins, chopped apples, or berries

Milk
Eggs
Brown sugar
Melted butter
Cinnamon
until well combined.
Add the oats
Spread the raw rolled oats evenly in the prepared baking dish.
Pour and stir
Pour the milk-egg mixture over the oats and gently stir so everything is evenly distributed.
Bake
