useful recipes for prime rib for Every Meal
For a dependable second meal, the best leftover prime rib recipes ideas use gentle heat, sauce, crisp vegetables, horseradish, or potatoes to protect texture and create a clear contrast.
I narrow ideas for leftover prime rib by deciding whether prime rib should stay in pieces, be shredded, or become part of a sauce.
1. French Dip Sandwiches with Au Jus
This is the recipe I make first every single time. It takes 15 minutes and tastes like something from a high-end deli.
What you need: Sub rolls or hoagie buns, provolone or Swiss cheese, butter, and your leftover prime rib sliced thin. For the au jus, you will want beef broth, a splash of Worcestershire sauce, garlic powder, and a bay leaf.
How to make it: Warm thin slices of prime rib in a skillet with a splash of beef broth over medium heat just until heated through, about 2 minutes. Pile the meat onto toasted sub rolls, top with cheese, and broil for 60 seconds until melted. Serve with small bowls of warmed au jus for dipping.
My tip: Do not overheat the beef in the skillet. Thirty seconds per side is plenty. The goal is warm, not cooked further.
2. Prime Rib Hash with Eggs (Breakfast)
This breakfast hash is the reason I always save some prime rib for the morning after. The crispy edges on the potatoes pair perfectly with tender beef and a runny yolk.
What you need: 2 cups diced potatoes (Yukon Gold work best), 1 cup diced leftover prime rib, half a diced onion, 2 tablespoons of butter or leftover beef fat, salt, pepper, and paprika. Top with fried or poached eggs.
How to make it: Parboil the diced potatoes for 5 minutes, drain, and let them dry. Heat butter or beef fat in a cast iron skillet over medium-high. Add potatoes and cook undisturbed for 4 minutes until golden on one side. Add the onion and cook 3 more minutes. Stir in the diced prime rib and cook 2 minutes just to warm through. Season generously and serve topped with eggs.
My tip: If you saved any fat trimmings from the roast, render them down and use that instead of butter. The flavor is incredible.
3. Prime Rib Stroganoff
Classic beef stroganoff gets a serious upgrade when you use leftover prime rib instead of tough stew meat. The entire dish comes together in about 30 minutes.
What you need: 1 pound leftover prime rib cut into strips, 8 ounces egg noodles, 1 onion sliced, 8 ounces mushrooms (button or baby bella), 2 tablespoons butter, 2 tablespoons flour, 1 cup beef broth, half a cup of sour cream, salt, pepper, and a teaspoon of paprika.
How to make it: Cook egg noodles according to package directions and set aside. In a large skillet, melt butter over medium heat and saute the onions until soft, about 5 minutes. Add mushrooms and cook until browned. Sprinkle flour over the vegetables and stir for 1 minute. Pour in beef broth and bring to a simmer until slightly thickened. Remove from heat and stir in sour cream. Fold in the prime rib strips and let them warm gently in the sauce. Serve over noodles.
My tip: Take the skillet off the heat before adding sour cream to prevent curdling. The residual warmth is enough to bring everything together.
4. Leftover Prime Rib Tacos
These tacos were inspired by a thread I found on a cooking forum where users kept raving about how leftover prime rib makes the best steak tacos. They were right.
What you need: Corn or flour tortillas, leftover prime rib sliced thin, a quick salsa (diced Roma tomatoes, onion, cilantro, lime juice, and a minced chipotle in adobo), crumbled cotija cheese, and lime wedges.
How to make it: Heat a cast iron griddle or skillet over high heat. Sear the thin slices of prime rib for 30 seconds per side just to get some char and warmth. Warm the tortillas directly on the griddle. Assemble with beef, salsa, cheese, and a squeeze of lime.
My tip: The chipotle in adobo is what makes this salsa special. Just one pepper, minced fine, adds smoky depth without overwhelming heat.
5. Prime Rib Philly Cheesesteak
Thinly sliced prime rib makes an outstanding cheesesteak. The marbling in the meat means you get that authentic melt-in-your-mouth texture without needing processed cheese product.
What you need: Hoagie rolls, leftover prime rib sliced paper-thin, sliced onions and bell peppers, provolone or Cheez Whiz, and butter.
How to make it: Melt butter in a skillet and saute sliced onions and peppers until softened and caramelized, about 8 minutes. Push vegetables to one side. Add the thinly sliced prime rib to the other side and cook 1 minute until just warmed. Combine meat and vegetables, top with cheese, cover the skillet for 30 seconds to melt. Scoop onto a toasted hoagie roll.
6. Prime Rib Ragu over Pappardelle
What you need: Leftover prime rib cubed or shredded (about 1 pound), 1 can crushed tomatoes, half an onion diced, 3 garlic cloves minced, half a cup of red wine, 2 tablespoons olive oil, dried oregano and thyme, pappardelle pasta, and grated Parmesan.
How to make it: Heat olive oil in a Dutch oven over medium heat. Saute onion until soft, then add garlic for 30 seconds. Pour in the red wine and scrape up any bits. Add crushed tomatoes, herbs, and the cubed prime rib. Reduce heat to low and simmer uncovered for 30 to 45 minutes, stirring occasionally. The meat will absorb the sauce and become incredibly tender. Serve over cooked pappardelle with plenty of Parmesan.
7. Prime Rib Pot Pie
This pot pie turns leftover prime rib into the ultimate comfort food. The flaky crust and creamy filling make it feel like a brand-new meal, not a leftover repurpose.
What you need: Leftover prime rib cubed (about 1.5 cups), mixed vegetables (peas, carrots, celery), 1 onion diced, 3 tablespoons butter, 3 tablespoons flour, 1.5 cups beef broth, half a cup of milk, a sheet of puff pastry or pie crust, and one egg beaten for egg wash.
How to make it: Preheat oven to 400 degrees. In a skillet, melt butter and saute onion and celery until soft. Whisk in flour and cook 1 minute. Gradually add beef broth and milk, whisking until smooth and thickened. Stir in the cubed prime rib and mixed vegetables. Transfer to a baking dish, top with pastry, brush with egg wash, and cut slits for steam. Bake 25 to 30 minutes until golden and bubbling.
8. Prime Rib Quesadilla
This is my quick-lunch favorite. It takes 10 minutes from start to finish and satisfies every time.
What you need: Large flour tortillas, leftover prime rib diced small, Monterey Jack or pepper Jack cheese, sliced jalapenos (optional), and butter or oil for the pan.
How to make it: Lay a tortilla flat and sprinkle cheese on one half. Add diced prime rib and jalapenos if using. Top with more cheese and fold the tortilla in half. Cook in a buttered skillet over medium heat for 3 minutes per side until golden and the cheese is fully melted. Cut into wedges and serve with salsa and sour cream.
9. Prime Rib Pho (Slow Cooker)
This is one of my favorite slow cooker leftover prime rib recipes. The bones and meat scraps simmer for hours, creating a fragrant, deeply satisfying Vietnamese-inspired soup.
What you need: Leftover prime rib bones plus any meat scraps, 8 cups water, 1 onion halved, a 2-inch piece of ginger sliced, 2 tablespoons fish sauce, 1 tablespoon sugar, star anise, cinnamon stick, rice noodles, and toppings like bean sprouts, basil, lime, and Sriracha.
How to make it: Char the onion and ginger halves under a broiler or over an open flame until blackened in spots. Place the bones, charred onion, ginger, spices, water, fish sauce, and sugar in a slow cooker. Cook on low for 6 to 8 hours. Strain the broth and discard solids. Cook rice noodles separately according to package. Serve the hot broth over noodles with thinly sliced leftover prime rib and your choice of toppings.
My tip: If you have leftover prime rib bones, this is the single best use for them. The marrow adds richness you cannot get from regular beef broth.
10. Prime Rib Beef and Barley Soup
Hearty, warming, and perfect for a cold evening. This soup stretches your leftovers into a full meal for four people.
What you need: Leftover prime rib cubed (about 1 cup), 6 cups beef broth, half a cup pearl barley, 2 carrots diced, 2 celery stalks diced, 1 onion diced, 2 cloves garlic minced, olive oil, bay leaf, salt, and pepper.
How to make it: Heat olive oil in a large pot and saute onion, carrots, and celery for 5 minutes. Add garlic and cook 30 seconds. Pour in beef broth, add barley and bay leaf, and bring to a boil. Reduce heat and simmer 30 minutes until barley is tender. Add the cubed prime rib in the last 5 minutes just to warm through. Season to taste and serve with crusty bread.
11. Steak Salad with Blue Cheese
For a lighter option that still feels indulgent, this salad is perfect. Cold prime rib sliced thin over greens with a tangy dressing is a restaurant-quality lunch.
What you need: Mixed greens or arugula, leftover prime rib sliced thin (served cold or room temperature), crumbled blue cheese, cherry tomatoes halved, toasted walnuts, and a simple vinaigrette of olive oil, red wine vinegar, Dijon mustard, and honey.
How to make it: Arrange greens on a plate or platter. Top with thin slices of cold prime rib, blue cheese crumbles, tomatoes, and walnuts. Whisk together the vinaigrette ingredients and drizzle over the salad just before serving.
My tip: If you want a low-carb option, this salad is naturally keto-friendly. Skip the honey in the dressing and use a pinch of stevia instead.
12. Prime Rib and Eggs Breakfast Skillet
Even simpler than the hash, this skillet is for mornings when you want something fast but satisfying. It takes 10 minutes total.
What you need: Leftover prime rib diced, 2 to 3 eggs, butter, salt, pepper, and fresh chives or parsley for garnish.
How to make it: Melt butter in a small cast iron skillet over medium heat. Add diced prime rib and warm for 1 minute. Crack the eggs directly into the skillet alongside the beef. Cover and cook until the whites are set but yolks are still runny, about 3 to 4 minutes. Season, garnish with herbs, and serve straight from the skillet.
What to Do with Leftover Prime Rib Bones
Most people toss the bones or make a basic broth. But those bones are packed with marrow and flavor that can elevate multiple dishes. Here are three ways to use them fully.
Make a rich bone broth: Place the bones in a slow cooker with water, a splash of apple cider vinegar, onions, carrots, and celery. Cook on low for 12 to 24 hours. Strain and use as a base for soups, risottos, or sip it on its own with a pinch of salt. Bone broth freezes well for up to 3 months.
Roast the marrow bones: If your leftover bones have exposed marrow, roast them at 450 degrees for 15 minutes until the marrow is soft and bubbly. Scoop it out and spread on toasted baguette slices with flaky salt and parsley. This is a restaurant appetizer you can make at home in 20 minutes.
Use bones for French dip au jus: Simmer the leftover bone in 2 cups of water with garlic, onion, and peppercorns for 30 minutes. Strain and reduce slightly. This makes the most flavorful au jus you will ever taste for your French dip sandwiches.
How to Reheat Leftover Prime Rib Without Drying It Out
This is the number one question I get asked, and it is also one of the most common PAA questions online. The key is gentle, low heat and moisture. Here are the three best methods I have tested.
Method 1: Low Oven with Beef Broth (Best for Slices)
Preheat your oven to 250 degrees. Place the prime rib slices in a baking dish and add a quarter inch of beef broth or au jus to the bottom. Cover tightly with foil and heat for 20 to 30 minutes depending on thickness. The broth creates steam that keeps the meat moist while the low temperature prevents further cooking.
Method 2: Skillet with Au Jus (Best for Quick Reheating)
Heat a skillet over medium-low heat. Add a splash of beef broth or au jus. Place thin slices of prime rib in the liquid for 30 seconds per side. This method is fast and works perfectly when you are building sandwiches or tacos.
Method 3: Sous Vide (Best for Preserving Doneness)
If you have a sous vide circulator, this is the ultimate method. Set the temperature to 5 degrees below your original doneness target. For medium-rare leftovers, set it to 125 degrees. Vacuum seal the prime rib and cook for 45 minutes to 1 hour. The meat warms evenly without any risk of overcooking.
What NOT to do: Never microwave prime rib on high power. It will cook the meat further and dry it out in seconds. Never reheat at temperatures above 300 degrees. High heat causes the proteins to seize and squeeze out moisture, leaving you with tough, gray beef.
Storage Guidelines for Leftover Prime Rib
Proper storage makes all the difference in how your leftovers taste the next day. Here is what you need to know.
In the refrigerator: Leftover prime rib will last 3 to 4 days when stored properly. Wrap the meat tightly in plastic wrap or store in an airtight container. Keep it in the coldest part of your fridge, usually the back, not the door.
In the freezer: You can freeze leftover prime rib for 2 to 3 months. Wrap each portion individually in plastic wrap, then place in a freezer bag with the air pressed out. Label with the date. Thaw overnight in the refrigerator, never at room temperature.
For the bones: Store leftover bones in a freezer bag and freeze them until you are ready to make broth. They will keep for up to 3 months and actually develop more concentrated flavor over time.
According to the USDA food safety guidelines, cooked beef should be refrigerated within 2 hours of cooking to prevent bacterial growth. When in doubt, use your senses. If the meat has an off smell, slimy texture, or discoloration, discard it immediately.
Wrapping Up: Make the Most of Every Slice
Finding the useful recipes for prime rib does not have to be complicated. With these 12 recipes plus my reheating and storage methods, you can turn holiday leftovers into meals that feel completely new.
Start simple with the French dip or breakfast hash. Then work your way up to the ragu or slow cooker pho when you want something more ambitious. And please, do not throw away those bones. They are liquid gold for soups, broths, and even roasted marrow.
The beauty of prime rib is its versatility. Every slice, scrap, and bone has potential. Experiment with these ideas, adjust the seasonings to your taste, and you will never look at leftovers the same way again.
The most useful best leftover prime rib recipes ideas also scale to the quantity available, so a small portion can flavor a larger base without feeling sparse.
Among these ideas for leftover prime rib, I favor the method that adds the least extra heat while still giving the dish a fresh finish.
Frequently Asked Questions
What is the safest way to store prime rib?
Refrigerate it promptly in a shallow, airtight container and use it within the safe window in the USDA leftovers guidance.
Should I reheat prime rib before adding it to a recipe?
