How to Make Leftover Prime Rib Sandwich

Step 1: Butter the Bread

Start by buttering two pieces of bread on one side each. This step is crucial because it helps achieve that golden-brown crust when you grill the sandwich. Plus, who doesn’t love buttery bread?

Step 2: Assemble the Sandwich

Next, lay down your sliced prime rib on one piece of bread. Don’t be shy—if you love prime rib as much as I do, feel free to pile on more! This hearty layer sets the stage for all those wonderful flavors.

Step 3: Add Sauce and Onions

Now it’s time to drizzle on the horseradish sauce and sprinkle the caramelized onions over the top. The horseradish adds a nice zing while the onions bring sweetness that balances everything beautifully.

Step 4: Grill It Up!

Place the other slice of bread on top, buttered side down. Heat a skillet over medium heat and grill your sandwich until it’s golden brown and crispy. This step not only warms everything through but also melds those flavors together perfectly.

Step 5: Slice and Serve

Once your sandwich is grilled to perfection, cut it in half and serve immediately. Enjoy every bite as you revel in how easy and delicious this meal is!

And there you have it—a delightful Leftover Prime Rib Sandwich that takes minimal effort but delivers maximum flavor. I hope this becomes a favorite recipe in your home just like it has in mine!
