Use a 4-quart slow cooker sprayed with cooking spray. In a mixing bowl, whisk together all the ingredients, taking care to not break down the whole corn kernels – the batter will be quite thick. Spread the batter into a prepared 4-quart slow cooker.
Cover and cook on low for 4-5 hours, or on high for about 3 hours. Uncover and cook on high for 1 hour, or until the casserole has lightly browned on top and begun to pull away from the sides. Serve warm or at room temperature.

Notes
Note: If you’d like to make this more of a complete meal, you can add a can of drained green chilies to the mix and a cup of diced ham or fully cooked smoked sausage.
