Ingredients Method Notes

Ingredients
  

  • 1 ½ lbs leftover prime rib, or other steak (about 4-6 oz per person)
  • 1 white onion, sliced
  • 8 slices provolone cheese
  • 2 cups arugula, (or other crunchy green, lightly packed)
  • 1 large baguette
  • For the Horseradish Cream Sauce:
  • ¾ cup sour cream
  • 3 tablespoons horseradish
  • 1 tablespoon Dijon mustard
  • 2 tablespoons fresh squeezed lemon juice
  • 1 tablespoon white wine vinegar
  • ½ teaspoon kosher salt
  • 2 tablespoon fresh chives, finely chopped

Method
 

  1. Preheat oven to 325 degrees Fahrenheit.
  2. Heat 2 tablespoons olive oil in a large pan over medium heat and add the sliced onions.
  3. Cook onions, stirring occasionally, until soft and caramelized, about 30-40 minutes.
  4. Place leftover prime rib in an oven-safe pan and heat in the oven for 15-20 minutes.
  5. Remove steak and slice thinly.
  6. Cut the baguette into 4 equal pieces and slice each piece lengthwise.
  7. Lay the bottom halves on a baking sheet and top each with two slices of provolone cheese.
  8. Place under the broiler for a few minutes until the cheese melts, watching closely to prevent burning.
  9. Build each sandwich by layering warm steak slices, a handful of arugula, caramelized onions, and then 1-2 tablespoons of horseradish cream sauce.
  10. Mix all horseradish cream sauce ingredients in a bowl until well combined.
  11. Serve sandwiches immediately and enjoy.

Notes

  • If your steak is already sliced, warm it on the stovetop or add it just before broiling the cheese. You can also serve the sandwiches cold or substitute ham or other steak roasts as desired.
