Corn pudding and corn casserole are popular side dishes in American cuisine, especially during the holidays. While they have similar ingredients, they differ in texture and consistency. Corn pudding has a creamy and loose texture, similar to dessert pudding, while corn casserole has a thicker consistency due to the use of thickening agents like instant cornbread mix. Corn pudding is thought to have Native American roots and is commonly served across the southern United States. On the other hand, corn casserole is a variation of corn pudding and uses instant corn muffin mix for a thicker texture.
