How to Reheat a Prime Rib Slice: A Complete Guide


Prime rib is a succulent and flavorful cut of beef that many people enjoy. However, leftovers can be a common occurrence after indulging in this delicious dish. If you find yourself with leftover prime rib slices, fret not! In this guide, we will walk you through step-by-step instructions on how to reheat your prime rib slice to perfection.

The Best Methods for Reheating Prime Rib Slices

Dry Heat Methods:

Oven Method:

1. Preheat your oven to 250°F (120°C).
2. Place the prime rib slice on a baking sheet lined with aluminum foil.
3. Sprinkle the meat lightly with some water or beef broth for added moisture.
4. Cover the baking sheet loosely with another piece of foil.
5. Place the baking sheet in the preheated oven and heat for about 10-15 minutes until warmed through without overcooking.
6. Check the internal temperature using a meat thermometer – it should read around 130°F (54°C) for medium-rare doneness.
7.Remove from the oven, tent loosely with foil, and let it rest for about five minutes before serving.

Pan-Searing Method:

1.Heat a skillet or frying pan over medium-high heat and add a small amount of oil or butter.
2.Place the prime rib slice in the hot pan and sear each side quickly for about one minute until heated evenly throughout.
3.Turn off the heat and remove from the skillet promptly once warmed through.
4.Allow it to rest for approximately three minutes before serving.

Moist Heat Methods:

Au Jus Bath Method:

1.Pour beef broth or au jus sauce into a saucepan and heat it over medium-high heat until simmering.
2.Place the prime rib slice in a shallow dish that can hold the liquid comfortably.
3.Pour the heated au jus or beef broth over the meat, ensuring it covers at least half of the slice.
4.Cover the dish with aluminum foil to retain moisture and prevent heat loss.
5.Allow the prime rib slice to soak in this flavorful bath for around five minutes until sufficiently warmed through.
6.Remove from the liquid carefully, letting any excess drip off before serving.

Sous Vide Method:

1.Prepare your sous vide cooker by filling a pot or container with water according to manufacturer instructions.
2.Set your sous vide device to 130°F (54°C) for medium-rare doneness. If cooked differently initially, adjust accordingly based on desired doneness level (e.g., higher temperature for well-done).
3.Seal each individual prime rib slice in an airtight bag using a vacuum sealer or zip-lock bags following water displacement method if necessary.
4.Immerse sealed bags completely in preheated water and cook for about one hour until thoroughly reheated without overcooking.
5.Remove from water bath, pat dry gently with paper towels, and proceed with serving immediately.
