- Gently warming the prime rib slices can significantly enhance their texture and flavor. You can do this by briefly sautéing them in a skillet with a touch of your preferred cooking fat (like butter or olive oil) for 1-2 minutes per side, or by placing them on a baking sheet and warming them in a low oven (around 250°F / 120°C) for 5-10 minutes. Avoid overcooking, as you want them to remain tender.1 pound thinly sliced cooked prime rib
