Why Make This Recipe
Prime rib is a delicious cut of beef and we love the flavor so we do not want it to go to waste. Layering the sliced beef on a crispy bread then topping with a slice of cheese and peppers and onions makes the best sandwich.
My family loves when we have leftover prime rib as they know that these sandwiches will be made. Serve with one of these Best Side Dishes for Sandwiches for a complete meal idea.

Variations Ideas
- Different Types of Bread – You could also use baguettes, Easy Homemade Artisan Bread Recipe, hoagie roll, French Bread, Sourdough or even hamburger buns for a different variety of textures and flavors.
- Prime Rib – This recipe works well with other types of leftover roast beef.
- Cheese – We love the way that the slices of provolone cheese melts on this leftover prime rib sandwich recipe. But you can also use swiss cheese or pepper jack cheese.
- Toppings – You can easily add your favorite toppings to this sandwich. Slice mushrooms and fresh arugula are a delicious addition.
- Sauce – This sandwich is even better with your favorite sauce. We have made a mayo and horseradish cream and added to the bread for added flavor.
Step by Step Instructions
Step 1 – In a small bowl, stir together mayonnaise, Dijon mustard, and minced garlic. Set aside.
Step 2 – Heat 1 tablespoon of olive oil in a large skillet over medium heat.
Step 3 – Add the sliced onions and green bell pepper, season with salt and pepper, and cook until they are soft and slightly caramelized, about 7-10 minutes. Remove from the skillet and set aside.
Step 4 – In the same pan, add the remaining tablespoon of olive oil. Add the thin slices prime rib and cook for a few minutes just until heated through. Be careful not to overcook, as the meat is already cooked.
Step 5 – Preheat the oven’s broiler and cut the sandwich rolls or ciabatta bread in half. Place on a baking sheet. Spread the mayonnaise and mustard mixture on both sides of each roll.
Step 6 – Divide the warm prime rib among the four rolls. Top with the cooked onions and bell peppers. Place a slice of provolone cheese on top of each sandwich.
- Step 7 – Place the open sandwiches under the broiler for 1-2 minutes, or until the cheese is melted and bubbly and bread has a crispy texture. Watch closely to avoid burning. Assemble the sandwiches and serve immediately.
Recipe Tips
- Cooking Time – Watch the sandwiches closely while broiling to ensure the cheese melts without burning the bread. The broiling time might vary depending on the oven, so it’s important to stay close by.
