This Parmesan Cheddar Grits Pudding is a rich and satisfying dish that transforms humble corn grits into a luxurious meal. By combining cooked grits with sautéed spinach, fresh green onions, and garlic, then binding them with eggs and generous amounts of cheddar and Parmesan cheese, you get a texture that is both creamy and firm. The baked top becomes golden and slightly crisp, contrasting beautifully with the soft interior. It makes for an impressive brunch centerpiece, a hearty breakfast for a crowd, or even a savory side dish for dinner. The flavors are deep and savory, with the earthiness of the spinach balancing the sharpness of the cheeses. Simple ingredients come together to create a comforting, home-style dish that feels indulgent yet is straightforward to prepare.
