At what temperature do you cook a 6 pound corned beef brisket?

To cook a 6-pound corned beef brisket, set your oven to 300°F (150°C). Slow-cook the brisket for about 3 to 4 hours, or until it reaches an internal temperature of at least 190°F (88°C) for optimal tenderness. Alternatively, you can simmer it in a pot on the stovetop for a similar duration. Always ensure it is fully cooked and tender before serving.
