Ingredient Rundown

• 2 cups potatoes, diced: Yukon Gold or Russet potatoes work best for that perfect crispy texture on the outside and fluffy inside.
• 1 tablespoon olive oil: For sautéing the potatoes and onions, adding a subtle fruity note and healthy fats.
• 2 tablespoons butter: Enhances richness and helps achieve that golden crust on the hash.
• 1 medium onion, finely diced: Adds sweetness and depth to the hash when caramelized.
• Salt, to taste: Essential for bringing out all the flavors and seasoning the dish properly.
• Black pepper, to taste: Adds a hint of warmth and spice to balance the rich beef.
• 2 cups prime rib, cooked and thinly sliced: Your star ingredient, leftover prime rib adds incredible flavor and protein.
• Fresh parsley, chopped, for garnish: Brightens the dish with a fresh herbal note and a pop of color.
• 4 large eggs, cooked (sunny side up, fried, or poached): The perfect finishing touch—soft yolks create a luscious sauce when broken over the hash.

Cook’s Kit

• Large non-stick skillet or cast-iron pan: Ideal for even cooking and crisping the potatoes and prime rib.
• Sharp chef’s knife: For dicing potatoes and onions precisely.
• Cutting board: To prep all ingredients safely and efficiently.
• Spatula or wooden spoon: For stirring and turning the hash without breaking it apart.
• Slotted spoon: Helpful if you choose to poach the eggs.
• Paper towels: To pat dry the potatoes if needed, ensuring crispiness.
• Plate lined with paper towels: For draining excess oil from the fried eggs if desired.

The Method for Leftover Prime Rib Hash

Step 1: Prep the Potatoes

Start by dicing your potatoes into small, even cubes—about ½-inch pieces work best for crisping up nicely. Rinse the diced potatoes thoroughly under cold water to remove excess starch, then pat them dry completely with paper towels. Dry potatoes will crisp better in the pan and avoid steaming.

Step 2: Sauté Potatoes and Onions

Heat the olive oil and 1 tablespoon of butter in your large skillet over medium heat. Once the butter has melted and is sizzling, add the diced potatoes. Spread them out evenly in the pan, letting them cook undisturbed for a few minutes until the bottoms start to turn golden brown and crisp. Then stir occasionally to brown all sides evenly. When the potatoes are about halfway cooked (about 8-10 minutes), add the finely diced onion. Continue cooking until the onions soften and the potatoes are tender and golden, about 5 more minutes. Season with salt and black pepper as you go.

Step 3: Add the Prime Rib

Toss in the thinly sliced leftover prime rib, stirring gently to combine it with the potatoes and onions. Cook for another 3-4 minutes, allowing the beef to warm through without overcooking. The prime rib should remain tender and juicy, absorbing the flavors of the skillet.

Step 4: Cook the Eggs

While the hash finishes cooking, prepare your eggs. You can fry them sunny side up or over easy in a separate pan with a little butter or oil. Alternatively, poach the eggs gently in simmering water for a silky finish. The choice is yours, but the key is to keep the yolks runny for that luscious sauce effect.

Step 5: Plate and Garnish

Divide the prime rib hash evenly across four plates. Top each serving with one cooked egg. Sprinkle generously with fresh chopped parsley for a burst of color and herbal brightness. Serve immediately while everything is warm and the eggs are perfectly gooey.

Ingredient Swaps & Substitutions

• Potatoes: Sweet potatoes or fingerling potatoes can be used for a different flavor and texture.
• Olive oil + Butter: Use avocado oil or ghee if you prefer dairy-free or a different fat profile.
• Prime rib: Substitute with leftover roast beef, steak, or even cooked lamb for a similar hearty protein.
• Onion: Shallots or leeks can add a milder, sweeter onion flavor.
• Eggs: If avoiding eggs, top with sautéed mushrooms or avocado slices for creaminess.
• Fresh herbs: Try cilantro or chives instead of parsley for a different herbal note.

Mistakes That Ruin Leftover Prime Rib Hash

• Not drying the potatoes: Wet potatoes steam instead of crisp, resulting in soggy hash.
• Overcooking the prime rib: Reheating the beef too long makes it tough and chewy.
• Skipping seasoning: Salt and pepper are essential to bring out the full flavor of every ingredient.
• Cooking eggs too much: Overcooked eggs lose that luscious yolk that ties the dish together.
• Using uneven potato sizes: Inconsistent pieces cook unevenly, leaving some underdone or burnt.

Freezer-Friendly Notes

You can prepare the hash mixture (potatoes, onions, and prime rib) ahead of time and freeze it in an airtight container for up to 2 months. When ready to eat, thaw overnight in the fridge, then reheat in a skillet over medium heat until warmed through and crispy again. Cook fresh eggs when serving for the best texture and flavor. Avoid freezing cooked eggs as they can become rubbery.

Common Questions

Can I make this recipe with fresh prime rib instead of leftovers?

Absolutely! If you have fresh prime rib, you can slice it thinly and add it to the hash near the end of cooking to warm it through. Just be careful not to overcook the beef, as the goal is to keep it tender and juicy.

What’s the best way to get crispy potatoes in this hash?

Drying the potatoes thoroughly before cooking and allowing them to cook undisturbed in a hot pan are key steps. Using a mix of butter and oil helps with browning without burning. Also, use a heavy skillet like cast iron for even heat distribution.

Can I use other vegetables in this hash?

Yes! Feel free to add diced bell peppers, mushrooms, or spinach for extra flavor and nutrition. Just add them at the right time—bell peppers early with the onions, mushrooms mid-way, and spinach last as it wilts quickly.

How do I reheat leftover Leftover Prime Rib Hash without losing crispiness?

Reheat it in a skillet over medium heat rather than the microwave. This helps restore the crisp texture. Add a little oil or butter if the hash seems dry. Avoid covering the pan so the steam doesn’t soften the potatoes.
