Preheat oven to 350 degrees F. Grease a 9 x 9 casserole pan with vegetable oil. Combine corn pudding ingredients in large bowl and pour into casserole dish. Bake for 45-50 minutes, until nicely browned around the edges.
To test for doneness, simply place a toothpick through center of pudding and if it comes out clean, the dish is done. If not, return to the oven and cook for an additional 7-10 minutes and re-test.
Once cooked through, remove from oven and let sit for 10 minutes before serving.
