Prepare Bread Base: Cube the bread into bite-sized pieces, and layer them evenly in a greased 9×13-inch baking dish. This will form a cozy base to soak up all that eggy goodness.

Mix Egg Mixture: In a mixing bowl, whisk together the eggs, milk, salt, and pepper until well combined. If you’re adding veggies, fold them in now. Pour this custard-like mixture evenly over the casserole layers.
-
Refrigerate: Cover the dish and let it chill in the refrigerator for at least 1 hour, or overnight if you want the flavors to mingle even more deliciously.
