How long to cook chuck roast and at what temperature?

The cooking time for a chuck roast can vary depending on the size of the roast and the desired level of doneness. As a general guide, here are some approximate cooking times:

- Small chuck roast (2-3 lbs): 2-3 hours

- Medium chuck roast (3-4 lbs): 3-4 hours

- Large chuck roast (4-5 lbs): 4-5 hours

These times are just a starting point, and you may need to adjust them depending on your specific oven and the desired level of doneness. To ensure the roast is cooked through, use a meat thermometer to check the internal temperature. The roast is done when it reaches an internal temperature of 145°F (63°C) for medium-rare, 160°F (71°C) for medium, or 170°F (77°C) for well-done.

Cooking Temperature:

The ideal cooking temperature for a chuck roast is 300°F (150°C). This temperature allows the roast to cook slowly and evenly, developing tender and flavorful meat. Avoid cooking the roast at a higher temperature, as this can result in dry and overcooked meat.
