This dish carries the comforting soul of a classic diner breakfast, updated for your home kitchen with a focus on texture and depth. It is a one-pan wonder that transforms leftover corned beef into a hearty, satisfying meal with perfectly crispy potatoes and savory beef.
For crispier potatoes, pat them dry after dicing. Do not crowd the pan when browning. Let the hash form a crust before stirring. Store leftovers in an airtight container for up to 4 days. Reheat in a skillet to maintain crispiness.
