Quick Answer: How Long To Cook Rib Roast In The Oven

The cooking time for a rib roast in the oven will depend on the weight of the roast and the desired level of doneness. As a general guideline, plan for approximately 15-20 minutes of cooking time per pound for a bone-in rib roast cooked at 350°F (175°C). For a boneless rib roast, reduce the cooking time to around 12-15 minutes per pound. This estimate assumes a starting oven temperature of around 450°F (232°C), which is then lowered to 350°F (175°C) after the roast is placed in the oven.

To determine the exact cooking time for your rib roast, it’s essential to use a meat thermometer to gauge the internal temperature. For rare, aim for an internal temperature of 120-125°F (49-52°C), for medium-rare 130-135°F (54-57°C), and for medium 140-145°F (60-63°C). Once the roast reaches the desired internal temperature, remove it from the oven and let it rest for at least 15-20 minutes before carving.

Choosing Rib Roast

Selecting the right rib roast is the first step towards a delectable main course. The rib roast, also known as prime rib, is taken from the primal rib section of the steer and is prized for its tenderness and rich flavor. When choosing a rib roast, consider the following factors:

Quality

Opt for a high-quality rib roast that is well-marbled with fat, as this will enhance the flavor and juiciness of the meat during cooking. Look for a roast with a generous layer of fat on the outside, known as the "cap", as this will help baste the meat as it cooks, adding to its succulence.

Size

Determine the size of the rib roast based on the number of guests and their appetites. A bone-in rib roast will typically have 2-7 ribs and can weigh anywhere from 4 to 30 pounds. Plan on approximately 1 pound of rib roast per person for a bone-in roast, or 3/4 pound per person for a boneless roast.

Bone-In Vs. Boneless

Consider whether you prefer a bone-in or boneless rib roast. A bone-in roast can offer extra flavor and moisture, while a boneless roast is easier to carve and may cook more evenly. Both options can yield delicious results, so the choice ultimately comes down to personal preference.

Preparing Rib Roast

Proper preparation is essential to ensure that your rib roast cooks evenly and retains its flavor and juiciness. Here’s a step-by-step guide to preparing a rib roast for the oven:

Bring The Roast To Room Temperature

Remove the rib roast from the refrigerator and let it sit at room temperature for 1-2 hours before cooking. Allowing the meat to come to room temperature ensures more even cooking.

Season The Roast

Season the rib roast generously with kosher salt, freshly ground black pepper, and any desired herbs or spices. A classic seasoning for rib roast includes a rub of minced garlic, fresh rosemary, and thyme, along with a drizzle of olive oil.

Tie The Roast (Optional)

If your rib roast is boneless, consider tying it with kitchen twine at regular intervals to help it hold its shape during cooking. This step is optional but can be beneficial for a more uniform roast shape and even cooking.

Preheat The Oven

Preheat the oven to 450°F (232°C) to create a beautifully seared crust on the outside of the rib roast.

Oven Temperature For Cooking Rib Roast

The oven temperature plays a crucial role in achieving the perfect rib roast.
