Notes
Overnight Instructions:
After you pour the egg mixture over the casserole in step 11, cover the casserole tightly and refrigerate overnight. The next morning, get the casserole out of the fridge and let it hang out on the counter for a bit while you preheat the oven to 350. When the oven is nice and hot, bake at 350 for 40-45 minutes until the edges are browned and bubbly, and the center doesn’t jiggle too much when you shake the pan. Let set for 5 minutes before serving.
*You can use half and half, cream, evaporated milk, or milk. The higher the fat content, the richer your casserole will be.
