Prep. Preheat the oven to 350º F. Butter a 9x13 baking dish. Set aside.
Cook the grits. Following my easy grits recipe, prepare the grits and stir in salt and pepper to season. Stir in the butter, cheese, eggs, and milk.
Bake the casserole. Pour into the prepared baking dish and place into the preheated oven. Bake until bubbling and the top of the grits casserole is golden brown, about 1 hour.
Cool and serve. Remove from the oven and allow to cool for 15 minutes. Serve warm.
