That magnificent prime rib roast was the star of your holiday dinner. But now, you’re staring at a sizable, delicious, and expensive chunk of leftover meat in your fridge. The biggest mistake you can make? Wasting it or, even worse, ruining it in the microwave.
In my kitchen, wasting prime rib is a cardinal sin. Over the years, I’ve made it my mission to transform these precious leftovers into meals so good, my family actually looks forward to them more than the original feast.
This guide is my complete playbook for honoring your leftover prime rib. We’ll cover the single most important reheating rule and then dive into more than 11 mouth-watering ideas, from 60-second lunches to gourmet dinners. Let’s make sure not a single delicious slice goes to waste.
Quick Summary: Best Uses for Leftover Prime Rib
- The Golden Rule: Never, ever use the microwave. The key is to reheat prime rib low and slow to preserve its tenderness and temperature.
- Best for a Quick Lunch: The Ultimate Prime Rib Sandwich or Quick Philly Cheesesteaks.
- Best for a Hearty Dinner: Hearty Prime Rib Stroganoff or a comforting Beef and Barley Soup.
- Best for a Crowd: Prime Rib Sliders or Loaded Nachos.
- Storage is Key: Store leftover prime rib whole if possible, tightly wrapped in the fridge, for 3-4 days.
The Golden Rule: How to Reheat Prime Rib Without Ruining It
Before we get to the recipes, we need to cover the most crucial step: reheating. Zapping a beautiful slice of medium-rare prime rib in the microwave will turn it into a gray, rubbery tragedy in seconds.
What I’ve found works best is the gentle oven method. It’s a simple technique that protects your investment.
Here are the baby steps:
- Preheat Your Oven: Set it to a low temperature, around 250°F (120°C).
- Place and Hydrate: Place your slices of prime rib in a small baking dish. Add a splash of liquid—about a tablespoon of beef broth or au jus—to create a little steam. This is my secret to keeping it moist.
- Cover and Warm: Cover the dish tightly with aluminum foil.
- Heat Gently: Place it in the oven for about 10-15 minutes, or just until the beef is warmed through. Don’t overdo it! The goal is to warm it, not cook it further.
Now that you know how to handle the meat, let’s get to the fun part!
11+ Delicious Ideas for Your Leftover Prime Rib Roast
Here are my family’s absolute favorite ways to use up every last bite of that glorious roast.
1. The Ultimate Prime Rib Sandwich
This isn’t just a sandwich; it’s an event. Thinly sliced, tender prime rib is the star, and it deserves the best supporting cast.

This is pure comfort food and comes together in under 30 minutes.
- The Steps: Sauté sliced mushrooms and onions in a pan with butter. Stir in a little garlic, then add some beef broth and a splash of Worcestershire sauce. Let it simmer, then turn off the heat and stir in a big dollop of sour cream.
- The Beef: Gently fold in bite-sized pieces of your prime rib at the very end, just to warm them through.
- Serve: Spoon this creamy sauce over hot egg noodles.
3. Quick Prime Rib Philly Cheesesteaks
Get that classic cheesesteak flavor in a fraction of the time.
- Prep Your Beef: Chop your leftover prime rib into small, thin pieces.
- Sauté Veggies: In a hot skillet (a cast-iron skillet works wonders here), sauté sliced onions and bell peppers until soft.
- Combine and Melt: Add the chopped beef to the pan and toss for 30-60 seconds to warm it. Top the pile of meat and veggies with slices of provolone or Cheez Whiz and let it melt.

4. Prime Rib and Egg Hash
Turn your leftovers into a five-star breakfast or brunch.

5. Comforting Beef and Barley Soup
This is the perfect way to use up the prime rib bone and any smaller scraps of meat.
- Build the Flavor: If you have the bone, use it to make a quick and rich beef stock. Otherwise, a high-quality store-bought beef broth works perfectly.
- The Soup: Sauté classic soup veggies (carrots, celery, onions). Add your beef broth, a cup of pearl barley, and herbs like thyme and bay leaves.
- Simmer: Let the soup simmer for about 45-60 minutes until the barley is tender.

7. Rich and Meaty Pasta Sauce
Dice your prime rib into small pieces and add it to your favorite tomato-based pasta sauce. Let it simmer for about 15-20 minutes to allow the flavors to meld. It adds an incredible depth and richness.
8. Prime Rib Sliders
Perfect for feeding a crowd or for a fun family meal.

- Bake: Cover with foil and bake at 350°F (175°C) for 15-20 minutes until the cheese is gooey and the rolls are toasty.
9. A Classic Shepherd’s Pie (Cottage Pie)
This is a fantastic way to use up smaller, diced pieces.

The ultimate game-day snack.
Spread tortilla chips on a baking sheet. Top generously with shredded prime rib, black beans, corn, and lots of shredded cheddar and Monterey Jack cheese. Bake until the cheese is melted and bubbly, then top with your favorite nacho fixings like jalapeños, sour cream, and guacamole.
11. Simple Steak Salad
For a lighter option, slice cold prime rib thinly and serve it over a bed of crisp arugula or mixed greens. Add some blue cheese crumbles, cherry tomatoes, red onion, and a balsamic vinaigrette for a gourmet salad in minutes.
