  • 4 medium potatoes diced into 1-inch pieces
  • 1/2 red onion diced
  • 2 clove garlic minced
  • 1 teaspoon fresh thyme
  • 3/4 teaspoon paprika
  • kosher salt to taste
  • 1 tablespoon olive oil
  • 8 ounces leftover prime rib see notes
  • 2 handfuls baby spinach
  • 3 green onions sliced
  • freshly ground black pepper to taste
  • 4 fried eggs or poached
  • red pepper flakes for serving (optional)


  • Preheat your oven to 400° and lightly spray a rimmed baking sheet with olive oil.
  • Add the diced potatoes, onions, garlic, thyme, paprika, a few generous pinches of kosher salt and drizzle with olive oil. Toss to combine and spread out evenly on the sheet pan. Roast for 20 minutes, rotating the pan halfway through.
  • Once the potatoes are tender, remove and turn your broiler on high. Use oven mitts to move your oven rack to the highest position.
  • Add the diced prime rib to the sheet pan and broil for 3 to 4 minutes or until the edges start to caramelize. Watch carefully to avoid burning.
  • Remove, turn off your oven and top with spinach. Toss and place the pan back into the oven to allow the spinach to wilt.
  • Meanwhile, fry up the 4 eggs.
  • Toss the hash one last time and season with freshly ground black pepper before dividing among plates, topping with a fried egg and sliced green onions.
