How long do you cook a 3.46 lb Corn beef brisket at 300 degrees?

The cooking time for a 3.46 lb corned beef brisket at 300 degrees Fahrenheit can vary depending on the cooking method and the specific cut of meat. However, here's a general guideline:

Using the oven with dry heat:

1. Preheat your oven to 300 degrees Fahrenheit (150 degrees Celsius).

2. Place the corned beef brisket in a roasting pan or baking dish.

3. Cover the brisket with aluminum foil to help retain moisture.

4. Cook the brisket in the preheated oven for approximately 3 hours and 30 minutes to 4 hours.

Using the stovetop with simmering liquid:

1. Place the corned beef brisket in a large pot or Dutch oven.

2. Cover the brisket with water or beef broth.

3. Bring the liquid to a boil over high heat, then reduce the heat to low and simmer for approximately 3 to 3 and a half hours.

It's important to note that cooking times can vary based on the actual size and thickness of the brisket, as well as the accuracy of your oven or stovetop temperature. To ensure that the brisket is cooked to your desired doneness, use a meat thermometer to check the internal temperature of the meat. The internal temperature should reach at least 160 degrees Fahrenheit (71 degrees Celsius) for medium-rare, 170 degrees Fahrenheit (77 degrees Celsius) for medium, and 180 degrees Fahrenheit (82 degrees Celsius) for well done.
