Chef John's Creamy Corn Pudding
You can leave some of the corn kernels out of the blender and stir them into the batter to give the pudding some texture if you like.
The pan under the baking dish is optional, and if you're in a hurry you can skip it which will cut about 15 to 30 minutes off your cooking time; but I like that it slows the cooking which I think improves the texture.
I used an 8x11-inch baking dish which is kind of an odd size. So if you use the more common 9x12-inch casserole, you'll have to test for doneness sooner as the batter will probably cook faster.
