With this expert guide, you’ll never wonder what to do with this flavorful meat again.

What is Prime Rib?

Prime rib is an iconic piece of meat that hails from the rib primal section of the cow. Also known as a standing rib roast, this cut is celebrated for its tenderness, marbling, and rich flavor profile with a well-balanced meat-to-fat ratio. Luckily, cooking a prime rib on the pellet grill is a straightforward and easy process.

Read all about cooking and serving prime rib for your next meal, and make sure to grab the following must-have Traeger accessories to make sure your rib roast is a success:

  • Flavorful Pellets: we recommend pellets with robust flavor profiles like Hickory or Mesquite.
  • Delicious Seasoning: Our Traeger Prime Rib Rub will provide your prime rib with a sweet and savory taste with its combination of rosemary and garlic.
  • Meat Thermometer: To achieve optimum results, use the MEATER Thermometer to monitor internal temperature. Make sure to insert it in the thickest part of the roast.

When it comes to prime rib though, the journey doesn’t end until the last slice is savored. Whether it's the seasoned outer crust or the perfectly medium-rare center, the leftovers of this dish can be repurposed for many other tasty meals.

How to Store Leftover Prime Rib

Properly storing your leftover prime rib is an essential step to reuse it for future meals. Either tightly wrap the meat in plastic wrap, or seal it in an airtight container – the more sealed the better. Leftover prime rib will keep for up to 4 days in the fridge, and 6 months in the freezer. To keep it juicy, keep the roast whole and cover it in au jus before packaging

What To Do with Leftover Prime Rib

From hearty sandwiches and savory stews to innovative appetizers and flavorful stir-fries, there are a ton of different options for what to do with leftover prime rib. To reheat your prime rib on the Traeger, put the prime rib in a pan with a little au jus or water to keep it from drying out, cover it in foil, and heat at 250 to 300°F until warmed through.

Flat Top Stir Fry

Using leftover prime rib in stir fry is a brilliant way to transform this large piece of meat. Cut your leftover prime rib into thin strips and combine with traditional stir-fry vegetables like bell peppers, broccoli, and snap peas. In a hot wok or skillet, cook everything together with a savory sauce.

Cook everything on the Flat Top Grill and follow our Griddle Stir Fry recipe for best results(replace the chicken with your leftover prime rib).

French Dip Sandwich

Elevate the classic French Dip sandwich by using your leftover prime rib instead of traditional roast beef. Before assembling your delicious sandwich, place thinly sliced prime rib on the Traeger and let them warm up.

When it comes to choosing your cheese, make sure to get one with a high melting point like Swiss or gouda. Make sure to also pair this hearty sandwich with a delicious au jus and robust horseradish cream. Refer to our Traeger French dip sandwich recipe for a general gist of how to prepare it.

Shepherd’s Pie


Shepherd’s pie is not only the perfect cozy meal for a chilly day, but it’s also a great way to use leftover prime rib. By finely chopping the prime rib you can use it in place of cooked ground meat for a tasty and filling dinner.

For the best wood-fired results, bake your assembled shepherd's pie on the Traeger for 30 minutes at 350°F.

Leftover Prime Rib Salad

Leftover prime rib doesn’t always have to be reheated to be delicious. By lightly sprinkling your prime rib slices with salt for added flavor and texture, you’ll have protein for a flavorful and hearty salad. To keep up that wood-fired flavor, try out our grilled wedge salad recipe.


What’s a better pairing than meat and cheese? Repurpose your prime rib by cutting it into bite-size pieces and then dipping it in a velvety, melted blend of cheeses and savory herbs.

Philly Cheesesteak


Elevate your lunch game effortlessly by repurposing leftover prime rib into a delectable Philly Cheesesteak sandwich. Simply slice the prime rib into thin strips and sauté them with bell peppers and onions on the Flat Top Grill until they reach a tender, caramelized perfection.

Prime Rib Stroganoff

Although stroganoff is typically made with ribeye, tender prime rib offers a luxurious twist to this classic dish. Thinly sliced prime rib, sautéed with onions and mushrooms, bathed in a velvety sauce will create a tasty stroganoff experience that’s rich in flavor and indulgence.

Use our stroganoff with egg noodles recipe as inspiration for your next meal (just replace the ground venison meatballs with prime rib).
