It is best cooked on a slow and low heat by using an oven. The preparation of cooking a prime rib is followed by preheating the oven at 500°F. The prime rib is first cooked at 500°F for 15 minutes and then under lower temperature to 325° F of the oven, it is cooked for 10-15 minutes.

Why Does It Take That Long To Cook A Prime Rib?

Depending on the size of your prime rib and temperature, cooking time varies. The length of time to cook depends on the type of prime rib preference. Traditionally, prime rib is cooked by starting with a very high temperature of the oven to sear the exterior and then lowering the temperature to gently cook it through to the inside. So the heat is penetrating the meat slowly and the temperature inside the oven is so hot which cooks the outer layer with a nice medium-rare pinkness extending from edge to edge. The more fat and connective tissues, the more time it takes to cook a prime rib. If it is cooked in the correct time duration, the collagen will become moist and succulent.

Lowering the temperature and slow cooking breaks down the collagen of the rib and melts it, giving a nice and juicy texture. It also softens the connective tissues and makes them edible. High and dry heat creates delicious browning in the outer layer of tender cut with connective tissue to the surface. By the time, when the connective tissue is becoming edible, the muscle has completely overcooked. Before craving, it is important to let the prime roast sit for around 15 minutes. The sitting time holds the juice and flavors. The roast will still cook, because the internal temperature will rise another 10 degrees.

Conclusion

To cook a prime rib, it is important to choose the right method. The two basic methods are dry direct heat (e.g., roasting, grilling and searing) and moist indirect heat (e.g., steaming, boiling and braising). If the meat is tough when it is raw, it needs moist and direct heat to tenderize and if the meat is soft when it is raw, then it needs dry direct heat to make it tender and delicious. It is better to cook prime rib at high temperature for 15-20 minutes, and then lower the temperature for around 3-15 minutes. Therefore,the ideal time per pound is 30-35 min.
