Leftover Prime Rib Hash

Meaty shreds of beef, tender veggies, and yolky eggs make one incredible leftover prime rib hash! It’s a quick, easy breakfast and a great way to repurpose prime rib or pot roast dinner leftovers. Best of all, this beef hash recipe makes a delicious and hearty meal that works any time of the day!

We love a good beef hash for this breakfast, and this prime rib hash hits the spot. The great thing about our recipe is you can use any kind of tender beef leftovers you have on hand or even add to it with fresh vegetables cooked until tender.

If you make a smoked prime rib, the smoky flavors will add some extra yum to the hash. However, you can’t go wrong with a roasted prime rib. This recipe also works with our Slow Cooker Pot Roast or our Dutch Oven Pot Roast if you want to turn it into a pot roast hash.

It answers the age-old question of what to do with leftover prime rib or pot roast. Breakfast hash for the win!

How to Make Leftover Prime Rib Hash

Crisp bacon, tender beef, and veggies, plus yolky eggs that cook to perfection in the oven. This leftover beef hash has it ALL.

To make it, follow these simple steps (be sure to view the full recipe card at the bottom of the page for all the details and ingredient amounts).

  1. Cook the bacon until brown and crisp, then let the excess oil drain off on a paper towel.
  2. Sauté onion in the bacon fat, then add the diced potatoes, carrots and garlic, cooking until golden brown.
  3. Add the roast beef and seasonings to the mix. Press the mixture into the pan and make 4-6 wells in the hash.
  4. Crack an egg into each of the wells and transfer the skillet to the oven. Bake until the eggs are cooked to your liking.

Tips for the Best Results

  • When dicing up the potatoes and onions, make sure to cut them into small pieces, about 1/4-inch cubes or smaller. This will allow them to cook quicker.

    If you’re starting out with raw vegetables, you can shred them if you’d like.
  • Bake the hash until the eggs are how you like them. If you like soft-set eggs, cook them for about 6 minutes. For firm eggs, the hash will need to bake for about 14 minutes.

    The time will vary based on how deep you make the wells, so we recommend letting them cook for about 5 minutes, then checking on them every couple of minutes after that.
  • The White Tuxedo spice blend is optional but highly recommended. It has a medley of flavors that go perfectly with roast beef hash (sour cream, onion, horseradish, lemon).

Leftover Pot Roast Hash

Yield: 4 to 6 servings
Prep Time: 12 minutes
Cook Time: 18 minutes
Total Time: 30 minutes

We used the leftover potatoes, carrots and beef from pot roast to make a savory pot roast hash with smoked bacon. If you don’t have any leftover potatoes and carrots, start with raw veggies and cook them until they get tender. 


  • 4 to 6 slices of bacon, diced
  • 1 yellow onion, diced
  • 3 to 4 garlic cloves, minced
  • 2 cooked potatoes (leftover from pot roast) or 2 raw potatoes
  • 2 cooked carrots (leftover from pot roast) or 2 raw carrots
  • 2 cups cooked roast beef, chopped
  • 2 tablespoons Worcestershire sauce
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon crushed red pepper
  • optional: 2 to 3 tablespoons White Tuxedo spice blend
  • 1/4 cup beef broth or water
  • 4 to 6 eggs


  1. Preheat the oven to 375°F. (When the hash is finished cooking, you will bake the eggs on top). 
  2. Place a large skillet over medium-high heat and cook the chopped bacon until brown and crisp. Transfer the bacon to a paper towel to drain. Pour out all but 1 tablespoon of the bacon fat from the skillet.
  3. Add the onion to the skillet with the bacon fat. Sauté until soft and golden brown. While the onions cook, dice the potatoes and carrots. If you are using raw veggies, dice them small so they cook quickly.
  4. Toss in the garlic, diced potatoes, and carrots into the skillet and cook, stirring occasionally, until golden brown, about 5 minutes. If you are starting with raw veggies, cover with a lid and cook until the potatoes are tender in the center (about 10 minutes). 
  5. Add the roast beef, Worcestershire sauce, salt, pepper, red pepper flakes, and White Tuxedo seasoning (if using). If the hash seems too dry, splash 1/4 cup of water or beef broth into the skillet. 
  6. Press the hash down with a spatula for a few minutes until it gets crispy on the bottom. 
  7. Make 4 to 6 wells in the hash and crack an egg in the center of each well. 
  8. Place the skillet in the oven and bake until the eggs are cooked to your liking. It will take about 6 minutes for soft-set eggs and about 14 minutes for firm eggs.


  • Dice the potatoes and carrots into 1/4 inch cubes or smaller. If you are starting with raw vegetables, you can shred them if you want them to cook faster. 
  • When you cook the eggs, the timing will vary depending on how deep you make the wells and how firm you like your eggs. After they cook for 5 minutes, check on them every couple of minutes. 
  • The White Tuxedo spice blend is optional but highly recommended. It has a medley of flavors that go perfectly with roast beef hash (sour cream, onion, horseradish, lemon).
