To deep fry a turkey, you need to have enough oil to fully submerge the bird, which is typically around 3 to 6 gallons depending on the size of the turkey and the size of your fryer pot. A common method to determine the right amount is to place the turkey in the fryer pot, then fill the pot with water until the turkey is covered. Remove the turkey, mark the water level, empty the pot, and then fill it with oil up to the marked level. For example, a 9-pound turkey might need about 3 to 4 gallons of oil, while a 15 to 22-pound turkey can require 5 to 6 gallons of oil. It is essential not to overfill the pot to prevent oil spills and allow space for oil expansion when heated.

Peanut oil is often recommended for deep frying turkey due to its high smoke point and neutral flavor, but other oils with smoke points above 425°F can also be used safely. When frying, always ensure the turkey is fully thawed and dry to prevent dangerous oil reactions.

In sum:

• Use water displacement with the turkey to measure oil volume.
• Expect 3 to 6 gallons of oil depending on turkey size.
• Do not exceed the fryer’s maximum fill line for safety.
• Peanut oil or other high smoke point oils are best.

This approach ensures you use the correct amount of oil safely and effectively for deep frying a turkey.
