How Long to Cook a Frozen Jennie-O Turkey Breast

If you are starting with a frozen Jennie-O fully cooked turkey breast, you will need to allow some extra time for it to thaw and roast properly. Here are some general guidelines:

  • Small Breasts (3-5 lbs) – Thaw 24 hours in fridge then roast at 325°F for 1 1⁄2 – 2 hours.

  • Medium Breasts (5-7 lbs) – Thaw 36 hours in fridge then roast at 325°F for 2 – 2 1⁄2 hours.

  • Large Breasts (7-9 lbs) – Thaw 48 hours in fridge then roast at 325°F for 2 1⁄2 – 3 hours.

Always rely on a meat thermometer to check for doneness instead of just cooking times. The turkey should reach an internal temperature of 165°F.

If you are short on time, you can thaw the turkey breast in cold water, allowing 30 minutes per pound. Be sure to keep the turkey refrigerated once thawed.

How to Cook a Jennie-O Fully Cooked Fresh Turkey Breast

For fresh, fully cooked Jennie-O turkey breasts that don’t need thawing, follow these simple steps for roasting:

  • Preheat your oven to 325°F.

  • Place the turkey breast on a rack in a shallow baking pan. Be sure the rack elevates it above the bottom of the pan.

  • Cook skin side up for optimal browning and crispiness.

  • Roast for approximately 15-20 minutes per pound, until the internal temperature reaches 165°F when a meat thermometer is inserted into the thickest part.

  • For example, a 5 lb breast would take 1 1⁄2 – 2 hours to roast fully.

  • Once done, allow the turkey to rest for 10-15 minutes before slicing. The temperature will rise slightly as it rests.

  • Serve hot and enjoy! Refrigerate any leftovers within 2 hours.
