Prime Rib Cheesesteak
Tender slices of juicy prime rib are piled high with caramelized onions, melty provolone cheese, and served on a toasted hoagie roll for a hearty, flavor-packed Philly cheesesteak sandwich that’s perfect for lunch or dinner.
I specialize in Recipes for Prime Rib and creative ways to use up those leftovers. My Prime Rib Philly Cheesesteak Sandwich is the perfect example of how to give your roast a tasty second life.
The leftover prime rib featured in the pictured sandwich utilized my ribeye roast recipe with prime rib rub.
Ingredients To Make Philly Cheesesteak
Here are the main ingredients needed to make a Leftover prime rib Philly Cheesesteak recipe. The full list can be found in the recipe card.
- Leftover Prime Rib Steak For Philly Cheesesteak: I created and tested this recipe using one 1/4″-1/2″ slice of beef from a leftover prime rib roast. If you prefer more of a classic cheesesteak sandwich, shave or thinly slice the beef instead. While any leftovers will work, I recommend trying one of mine: Melt-In-Your-Mouth Prime Rib Roast, Reverse Seared Prime Rib, or Smoked Prime Rib.
- Vegetables: I stick to onions and green bell peppers, but it’s easy to also throw in sautéed mushrooms, or omit any.
- Cheese: while Cheez Wiz is authentic, you can also use Swiss or provolone (as I did here!)
- Bread: any hearty roll will work, such as French roll, hoagie roll, or baguette. You can also make or buy garlic bread for added flavor.

Reheating Prime Rib
During recipe testing, I found reheating the prime rib steak on the stovetop, with a splash of beef broth, beef au jus, or au jus mix, works the best. It’s extremely quick and keeps the leftover prime rib steak nice and moist.

Variations
Here are a few variation ideas to consider when making leftover prime rib Philly sandwiches:
Prime Rib Sliders: Use slider bread to make homemade philly cheesesteak sliders with prime rib instead of individual sandwiches.
Horseradish Philly Cheesesteak: While not traditional, add a layer of tangy horseradish sauce for a zesty kick.
Recipe Tips And Notes
- Salt: I highly recommend sticking to unsalted butter. The prime rib rub will be already high in sodium.
- If you used a crazy flavored prime rib seasoning mix, and are unsure if it will work in a Philly cheesesteak, just trim off the crust of the beef before using.
- Serve immediately for the best texture. The longer it sits, the softer the bread will become.
