How long does it take to cook a beef roast?

Cooking time for beef roasts can vary depending on the size and cut of the roast, the oven temperature, and your desired level of doneness. Here are some general guidelines for cooking times for beef roasts:

Small Beef Roast (2-3 lbs)

- Conventional Oven (350°F/175°C): 1 1/2 to 2 hours

- Slow Cooker (on Low): 8-10 hours

Medium Beef Roast (4-6 lbs)

- Conventional Oven (350°F/175°C): 2 1/2 to 3 hours

- Slow Cooker (on Low): 10-12 hours

Large Beef Roast (7 lbs and up)

- Conventional Oven (325°F/165°C): 3 1/2 to 4 hours

- Slow Cooker (on Low): 12-14 hours

Remember that these are approximate cooking times, and the actual time may vary depending on factors such as the exact cut of the roast and your oven's temperature. It is always a good idea to use a meat thermometer to check the internal temperature of the roast to ensure it has reached the desired doneness. For beef, the USDA recommends cooking it to an internal temperature of 145°F (63°C) for medium-rare or 160°F (71°C) for medium.
