Egg casseroles have been a staple of American home cooking since the early 20th century, originally popularized as a convenient way to use pantry staples for breakfast or brunch. The addition of cheese reflects the American love for dairy‑rich comfort foods, making it a beloved dish for family gatherings and weekend brunches.
