A comforting, crustless breakfast casserole featuring a rich custard base of cream cheese and eggs, mixed with sautéed spinach, onions, and salty feta cheese. It is simple to prepare, forgiving for beginners, and tastes like home.
Ensure spinach is thoroughly squeezed dry to prevent a watery casserole. Use room temperature eggs and cream cheese for a smooth custard. Do not overbake; the center should still jiggle slightly as it will set while cooling. For best results, use block feta packed in brine rather than pre-crumbled.
