Ingredients Equipment Method Notes

Ingredients
  

  • 4 rolls buns or sandwich rolls preferably crusty or toasted
  • 8-10 slices prime rib thinly sliced leftover roast
  • 1/4 cup horseradish prepared horseradish or horseradish sauce
  • 2 tablespoons mayonnaise
  • 1 clove garlic minced
  • 1 teaspoon fresh thyme chopped
  • 4 slices pickles crisp and tangy

Equipment

  • Toaster or oven
  • Chef's knife
  • Small mixing bowl
  • Spatula

Method
 

  1. Start by toasting the buns in a toaster or oven until golden and crispy—that adds a lovely crunch.
  2. Meanwhile, prepare the horseradish cream by mixing prepared horseradish, mayonnaise, minced garlic, and chopped thyme in a small bowl until smooth and fragrant.
  3. Lay out the sliced prime rib on a clean plate or cutting board, ensuring slices are thin enough to fit comfortably inside the bun.
  4. Spread a generous layer of the horseradish cream on the cut sides of each toasted bun.
  5. Layer the prime rib slices onto the bottom halves of the buns, pressing gently so they stay in place and release their juices slightly.
  6. Add a few slices of pickles on top of the beef to add texture and tang.
  7. Cover with the top halves of the buns, pressing down slightly to compact the fillings.
  8. If desired, give the assembled sandwiches a quick warm-up in the oven or under a broiler to meld flavors and crisp the bread further—about 2-3 minutes.
  9. Slice each sandwich in half for easier eating and serve immediately, enjoying the juicy beef with crunchy pickles and flavorful sauce.

Notes

You can customize the toppings with caramelized onions or different pickles. For extra flavor, toast the bread until just crispy before assembling.
