If your turkey is frozen, you need to ensure it is completely defrosted prior to cooking (see note 1).
Once your turkey is fully defrosted, open the package and remove the neck and giblets from the cavity of the bird and pat both the inside and outside of your turkey completely dry.
Inject your bird in the breast, legs, wings, and thighs leaving about 3" gaps between injections.
Season the bird all over with turkey rub. Make sure you season both sides of the turkey and lift up the wings and legs to season underneath. Every part of the turkey should be seasoned.
Let the turkey rest at room temperature for 30 minutes while you preheat your oil.
Pour your peanut oil into a 32-quart pot, turn on the propane and preheat the oil to 250°F.
Turn off the propane and slowly and gently lower your turkey into the fryer until it is fully submerged. When the turkey is submerged, turn the propane back on, and increase the oil temperature to 350°F.
Let the turkey fry for 30 minutes undisturbed, then gently lift the it out of the fryer and check the internal temperature in the breast with a probe thermometer. You want the turkey to reach 160°F internal temperature. If the turkey is not yet to 160°F, gently drop it back down into the oil and let it continue to fry in 10 minute increments until it reaches 160°F.
When your turkey reaches 160°F in the thickest part of the breast, remove it from the oil and let it rest for 10 to 15 minutes to cool slightly. During this rest period, the internal temperature will continue to increase to 165°F to 170°F.
