Preheat the oven to 350°F. Spray a 9" x 13" casserole dish with oil.
Break all of the eggs into a large bowl. Whisk them together with the milk, melted butter, salt, and pepper.
Pour the egg mix into your greased casserole dish.
Bake in the oven for 12 minutes. Take the dish out and use a fork to run through the egg to break it up into curds.
