How to Make Easy Roast Beef Hash Recipe (Using Leftover Roast Beef) Recipe

Step 1: Prepare the Potatoes

Start by peeling and cutting your potatoes into roughly half-inch cubes. This size helps them cook evenly and crisp up nicely in the skillet. Rinse them briefly to remove excess starch, which helps avoid mushy potatoes and gives you that delightful golden crust.

Step 2: Sauté the Vegetables

Heat your peanut oil in a large skillet over medium heat. Add the chopped sweet onions and green bell peppers, cooking until they become soft, fragrant, and slightly caramelized. This step is crucial for building the savory foundation of your hash.

Step 3: Cook the Potatoes

Add your cubed potatoes to the skillet and toss with the vegetables. Let them cook undisturbed for a few minutes to allow a golden crust to develop, then stir and continue to cook until the potatoes are tender but still firm. This gives you that irresistible combination of crispy outside and fluffy inside.

Step 4: Add Seasonings and Beef

Sprinkle in the kosher salt, black pepper, and ground thyme, stirring well to distribute the flavors. Gently fold in the leftover roast beef cubes or shreds, letting them warm through and mingle with the potatoes and vegetables.

Step 5: Make the Sauce

In a small bowl, whisk together the beef stock, Worcestershire sauce, and cornstarch. Pour this mixture into the skillet, stirring constantly until the sauce thickens and coats the hash beautifully. This step adds moisture and a savory glaze that brings everything together.

Garnishes

Fresh garnishes can elevate your roast beef hash dramatically. Try a sprinkle of chopped fresh parsley for color and brightness or some finely sliced green onions for a mild, oniony bite. A sunny-side-up egg on top adds comfort and richness that’s hard to beat.

Side Dishes

This hash is hearty enough to stand on its own, but serving it alongside a crisp green salad or some steamed seasonal vegetables helps balance the meal with a fresh and light touch. Toasted crusty bread or warm tortillas can also be excellent accompaniments when you want to scoop every last bit.

Creative Ways to Present

If you’re entertaining or simply want to make brunch feel special, consider plating the hash inside avocado halves or on puff pastry rounds for mini savory tarts. Alternatively, a ramekin can be used for individual portions baked with an egg on top for a beautiful, personalized dish.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer your roast beef hash to an airtight container and refrigerate. It will stay fresh for up to three days, making it perfect for quick lunches or breakfasts later in the week.

Freezing

You can freeze the hash in portion-sized airtight containers or heavy-duty freezer bags. When properly sealed, freezing extends its shelf life up to two months without losing flavor or texture.

Reheating

For the best texture when reheating, warm the hash gently in a skillet over medium heat to restore its crispiness. Avoid microwaving if possible, as this often results in soggy potatoes. Add a splash of beef stock if the hash seems dry.

FAQs

Can I use other types of leftover meat for this recipe?

Absolutely! While this is designed for leftover roast beef, cooked chicken can be delicious substitutions. Just keep in mind that the flavor profile may shift depending on the meat’s seasoning.

What if I don’t have beef stock?

If beef stock isn’t on hand, you can substitute with chicken stock, vegetable stock, or even water with a splash of soy sauce or Worcestershire to retain that umami depth.

How do I make this hash spicier?

For some heat, add a pinch of crushed red pepper flakes when sautéing the veggies or top the finished dish with a drizzle of hot sauce according to your preference.

Can I prepare this dish in advance and reheat it for breakfast?

Yes, this hash reheats wonderfully and is a fantastic make-ahead meal. Just reheat in a skillet to maintain crispiness rather than using a microwave.

Is this recipe suitable for gluten-free diets?
