You can freeze your leftover prime rib for up to 6 months.

How to Reheat Prime Rib

Knowing how to reheat prime rib is super important if you want to restore it to its former glory.

Luckily there are 5 different ways you can reheat prime rib.

How Do I Reheat Prime Rib in the Oven

Reheating prime rib in the oven is by far the best way to reheat prime rib.

Set your oven to 250°F, then arrange the prime rib in a baking dish along with 2-3 tablespoons of beef broth, pan gravy, or water. If you use water, it may alter the flavor of the prime rib.

Next, cover the prime rib with foil and cook it for 10 minutes until heated through.

Prime rib can continue to cook if it remains in the pan, yielding dry beef, so immediately place your prime rib onto a serving dish.

How to Reheat Prime Rib in a Steamer

A steamer or a double boiler is the perfect way to reheat prime rib gently.

However, the amount of water needed to steam prime rib can vary. Aim for 1-inch of water for a small steamer, 2 inches of water for a medium steamer, and 3 inches of water for a large steamer.

Add the water to the bottom of a pot, then add your steamer basket on top of the pot and place it over a medium-low flame.

Add the prime rib to a sheet of foil. Add 2-3 tablespoons of water, beef broth, or gravy to the prime rib and fold the foil to seal the prime rib in a pocket.

Place the prime rib into a steamer and cover the pot with the lid. Cook the prime rib for 3-6 minutes until heated through.

Remove the prime rib from the foil packet, place it onto a serving platter and drizzle it with the broth in the bottom of the packet.

Serve the prime rib immediately to prevent it from continuing to cook on the interior.

How to Reheat Prime Rib Using the Sous Vide Technique

Sous vide sounds intimidating. However, it is actually a popular way to reheat meat, especially if it’s rare prime rib.

In short, sous vide refers to using a vacuum sealer to seal the meat in a package and heating it in a water bath.

Therefore, sous vide is perfect for reheating sliced prime rib as it will not overcook the prime rib since it uses gentle heat.

Nevertheless, it will take at least 1 hour to reheat your prime rib using the sous vide technique. 

To reheat your prime rib, cut it into uniform pieces, then vacuum seal it. Heat your sous vide machine to 140°F.

If you desire a well-done or medium-well prime rib, increase the sous vide machine’s temperature to 165°F.

Next, add your vacuum-sealed prime rib into the sous vide machine and cook it for 1 hour.

Remove your prime rib from the vacuum-sealed pouch to prevent it from overcooking, and add salt and pepper or your preferred seasoning along with au jus.

Serve the prime rib immediately.

How to Reheat Prime Rib in the Air Fryer

Yes, you can reheat prime rib in the air fryer. Although it seems like you will overcook prime rib in the air fryer, the trick is to use a low temperature.

For example, if you reheat prime rib at 400°F, you will end up with dry overcooked prime rib.

However, if you reheat prime rib at 320°F, you will yield a tender and juicy prime rib that develops a beautiful brown crust on the slices of prime rib.

To reheat your prime rib in the oven, heat your air fryer to 320°F. Carve your prime rib into uniform medium-sized pieces.

Season the leftover prime rib with salt and pepper or your preferred seasoning and place it into the air fryer’s basket.

Cook the prime rib for 3 minutes and enjoy.

You can also prep your prime rib in advance, so you can heat it in the air fryer as soon as you walk through the door.

Simply slice it into slices, wrap it in foil and refrigerate it. Heat it in the air fryer at 320°F for 3 minutes until thoroughly heated and enjoy.

How to Reheat Prime Rib in the Microwave

The microwave is never recommended for reheating meat. 

The microwave can turn prime rib from a beautiful pin color to a dull gray and remove all of the moisture from the prime rib. 

However, if you do not have time to use one of the other methods for reheating prime rib listed above, the microwave is your best option.

To reheat your prime rib in the oven, slice our portion of prime rib, then arrange it in a microwave-safe bowl.

Add 2-3 tablespoons of beef broth to the prime rib and wrap the meat with heat-safe plastic rib or place the lid onto the bowl.

Cook the prime rib for 1-2 minutes just until it is heated through, then place it into a serving dish and serve immediately.
