How to Make Baked Oatmeal Casserole Step by Step?

Creating the Easy Baked Oatmeal Casserole is a straightforward process that yields hearty results.

Step 1

Start by preheating your oven to 350°F (175°C) and greasing a baking dish. This ensures the casserole cooks evenly and doesn’t stick.

Step 2

In a large bowl, combine the rolled oats, baking powder, and salt. Stir until mixed evenly to add structure and flavor to the base of the dish.

Step 3

In another bowl, whisk together the milk, honey or maple syrup, eggs, and vanilla extract until fully combined. This mixture will add moisture and sweetness to your casserole.

Pour this wet mixture into the dry ingredients and stir until well incorporated. Gently fold in the mixed berries and cinnamon (if using), being careful not to break the berries too much. Pour the mixture into the prepared baking dish, spreading it out evenly.

Bake for 25 to 30 minutes, or until the top appears golden and the mixture has set. Let it cool slightly before cutting into squares and serve warm.
