Transform your leftover roast beef into a delightful and hearty meal with this simple hash recipe. Perfect for breakfast, lunch, or dinner, this dish combines savory beef with crispy potatoes and sweet onions for a comforting and satisfying experience.
If you don't have leftover roast beef on hand, you can easily find it at your local supermarket or deli. Make sure to choose a cut that is already cooked and seasoned.

How To Store / Freeze This Dish
Allow the leftover roast beef hash to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
Transfer the cooled hash into an airtight container. For best results, use a container that fits the amount of hash snugly to minimize air exposure.
Label the container with the date to keep track of freshness. The hash can be stored in the refrigerator for up to 3-4 days.
For freezing, portion the hash into individual servings. This makes it easier to reheat only what you need.
Place the portions into freezer-safe bags or containers. Squeeze out as much air as possible before sealing to prevent freezer burn.
Label the bags or containers with the date. The hash can be frozen for up to 2-3 months.
When ready to reheat, thaw the hash in the refrigerator overnight. This ensures even reheating and maintains the texture.
Reheat the hash in a skillet over medium heat until warmed through. You can also use a microwave, but be sure to stir occasionally to heat evenly.
If the hash seems dry after reheating, add a splash of olive oil or a bit of broth to moisten it up.
Enjoy your reheated leftover roast beef hash with a fresh side salad or a slice of crusty bread for a complete meal.
