How to Cook a 9-Lb. Turkey Breast

Turkey breasts are known for providing a lean, flavorful source of protein that can be easily prepared in the oven. The average turkey breast weighs from 4 to 8 lbs., but sometimes you need a large turkey breast weighing 9 lbs. to accommodate a large dinner. While preparing a 9-lb. turkey breast follows the same basic procedure, cooking time is adjusted slightly so the internal temperature of the meat reaches the minimum safe amount.

Step 1

Preheat the oven to 325 degrees Fahrenheit.

Step 2

Rinse the turkey breast and pat dry with paper towels.

Step 3

Place the turkey breast skin side up on a roasting rack inside a roasting pan.

Step 4

Use a basting brush to apply a thin layer of vegetable oil to the top of the turkey breast.

Step 5

Place the turkey breast into the oven and cook for about 3 to 4 hours.

Step 6

Check the internal temperature of the turkey breast after 3 hours by inserting a meat thermometer into the thickest part of the meat.

Step 7

Remove the turkey breast when the internal temperature reaches 165 degrees.

Step 8

Allow the turkey breast to cool for 20 minutes before serving.
