How long do you cook a 4lb prime rib roast 200 degrees for medium rare to the rare?

Unfortunately, I can't give you an exact cook time for your prime rib.

Here's why:

* Oven variations: Each oven heats slightly differently.

* Roast shape and thickness: A 4lb roast can come in various shapes and thicknesses, affecting cook time.

* Desired level of doneness: "Medium rare to rare" is a range, and personal preference plays a role.

Here's how to get the perfect roast:

1. Use a meat thermometer: The only reliable way to ensure proper doneness is with a meat thermometer.

2. Target temperatures: For medium rare, aim for 130-135°F internal temperature. For rare, aim for 120-125°F.

3. Rest: After cooking, let the roast rest for at least 15 minutes before carving. This allows the juices to redistribute for a more tender and flavorful cut.

General guideline for a 4lb prime rib at 200°F:

* Expect a cook time of approximately 2-3 hours.

* Check the internal temperature frequently: Use a meat thermometer to monitor the temperature and adjust cooking time as needed.

Remember: It's better to undercook slightly than overcook. You can always pop it back in the oven for a few more minutes if needed.

Enjoy your perfectly cooked prime rib!
