The Ultimate Guide to Reheating Prime Rib for Maximum Juiciness

That flavorful prime rib roast from last night's dinner can easily shine again as a delicious leftover. Here are the best methods to reheat it and keep it mouthwatering.

Reheating Prime Rib: A Step-by-Step Guide

Proper storage is essential for preserving the quality of your leftovers, so let's begin with how to store cooked prime rib:

Storing Leftover Prime Rib

After dinner, wrap any leftover prime rib tightly in plastic wrap and place it in the fridge or freezer. For optimal flavor, consume it within five to seven days in the fridge or up to six months in the freezer. It's best to keep the prime rib whole rather than slicing it. If you have leftover au jus, drizzle some over the meat before wrapping it up. When reheating from frozen, let it thaw in the fridge for 24 hours before following the reheating steps.

Reheating Prime Rib the Right Way

Reheating prime rib without losing some of its signature pink hue can be challenging, but by reheating slowly, you can get pretty close to the original flavor. Focus on reheating the thickest part of the roast to maintain that medium-rare finish.

1. Place the leftover prime rib in a baking dish and cover with foil. To keep the meat juicy, add a little of the au jus from the previous meal, or pour in 1/4 cup of low-sodium beef broth.
2. Put it in a preheated oven at 300°F (150°C) for about 20 to 30 minutes, depending on the size of the roast. The USDA recommends reheating leftover meat to an internal temperature of 160°F (70°C), which is beyond the medium-rare level of 140°F (60°C). Unlike fresh prime rib (which should rest for 10 minutes), this reheated version doesn't need to rest before serving.
3. If maintaining the pinkness of the meat isn't a priority, you can microwave a slice of prime rib, heating it in 30-second intervals while checking the temperature between each cycle. This method is quicker but will reduce the meat's tenderness.

Ways to Use Leftover Prime Rib

Leftover prime rib can be piled onto an open-faced sandwich and toasted under the broiler for a few minutes. It can be chopped and cooked with potatoes for a savory hash or added at the end of making beef stroganoff. If you also have leftover mashed potatoes and vegetables, you can combine them with the reheated prime rib to recreate the original meal. But for something different, try making prime rib soup, stuffed baby Yorkies (a beefy take on Yorkshire pudding), or Asian-style beef and rice noodle soup, as shown below.
