How Long to Deep-Fry a 20-Pound Turkey

60 to 80 minutes is the usual frying time for a whole 20-pound turkey in a fryer rated for that size. Allow additional time for oil preheating and resting, and use a meat thermometer, not the clock, to decide when the turkey is ready. These planning times separate frying from the thawing you may need first.

Starting Point	Time to Allow	Important Condition
Fully thawed turkey in a suitably rated fryer	About 60 to 80 minutes of frying	Internal temperature determines doneness
Frozen turkey, thawed in the refrigerator	4 to 5 days before frying	Keep it refrigerated throughout thawing
Frozen turkey, thawed in cold water	About 10 hours before frying	Change the water every 30 minutes and cook immediately after thawing

Why Fryer Capacity Matters More Than Pot Size

Whole-bird frying times apply only when the fryer is rated to handle the whole bird.

A turkey can physically fit inside a pot without leaving enough room for oil displacement and bubbling. The basket, lifting equipment, oil-fill limit, and manufacturer’s maximum turkey weight all matter.

A large bird also presents a doneness problem: browned skin or a satisfactory breast reading does not prove that the thighs and other thick areas are cooked. That is why the process has two separate checks: confirming that the equipment can handle the turkey before cooking, then checking multiple parts of the bird before serving.

The cooking-time estimate helps you plan dinner. It does not override either check.

How to Deep-Fry a Large Turkey Safely

A large turkey can be deep-fried safely only when the fryer supports its whole-bird capacity and the bird is completely thawed.

Step 1: Confirm the Fryer’s Whole-Turkey Capacity

Confirm that the maximum turkey weight listed in your fryer’s manual or on its capacity label is at least 20 pounds.
Check whether that limit applies to a whole turkey, and confirm that the supplied basket or rack can accommodate it.
Choose whole-bird frying only when the equipment and cooking instructions explicitly support it.

Some extra-large indoor turkey fryers can accept a whole 20-pound turkey, but “extra-large” is not a standardized capacity. Do not assume that every model with that description can handle your bird.

The Food Town deep-frying method calls for separating the legs and thighs from the breast for turkeys weighing 15 pounds or more. That is a method-specific cutoff, not a universal rule for every fryer.

If your turkey exceeds the fryer’s whole-bird weight limit, use a smaller turkey, fry separate portions using a method intended for them, or roast the large bird instead. Adding less oil does not make an oversized turkey suitable for a fryer.

Step 2: Thaw the Turkey Completely

For refrigerator thawing, leave the wrapped turkey on a deep tray on the refrigerator’s bottom shelf. Allow 4 to 5 days for this size bird, according to Clemson Cooperative Extension.
For cold-water thawing, keep the turkey in leakproof packaging and completely submerged in cold water. Allow about 10 hours, change the water every 30 minutes, and cook immediately after thawing.
Once thawed, remove the wrapping, neck, and giblets.

Keep the refrigerator at 40°F or below. A refrigerator-thawed Butterball turkey may be held for up to 4 days before cooking under Butterball’s own guidance; Clemson’s general guidance for thawed turkey is 1 to 2 days. Use the shorter window unless the turkey’s own instructions specifically allow longer.

Do not thaw the turkey on the counter. Check both cavities and the areas around the joints for remaining ice; a thawed exterior does not guarantee a thawed center.

Step 3: Set Up the Fryer and Measure the Oil

Choose the operating location before adding oil.
Use a water-displacement test to measure the oil level for an outdoor pot, or the model’s specified oil level for an indoor electric fryer. Never exceed the fryer’s maximum-fill limit.
Make sure the pot and equipment are completely dry before oil goes in.

For an outdoor propane fryer, use a flat, noncombustible surface far from homes, garages, and wooden decks, following Shady Brook Farms’ outdoor turkey-frying safety guidance. Never leave the fryer unattended. Keep children and pets away from the cooking area.

A propane fryer belongs outdoors, not in a garage or under a building overhang. Indoor frying requires an electric appliance specifically approved for indoor use.

For an outdoor pot, a water-displacement method establishes the oil level:

Put the thawed turkey in its basket and lower it into the cold, empty pot.
Add water until the turkey is barely covered.
Lift the turkey out, allowing water from the bird to drain back into the pot.
Mark the resulting water level as the oil-fill guide.

Butterball’s outdoor method calls for 3 to 5 inches of headspace between the fill line and the top of the pot. Also obey the fryer’s maximum-fill restriction. If adequate coverage and clearance cannot both be achieved, the setup is unsuitable for that bird.

Empty the water and thoroughly dry the pot, basket, and lifting equipment before adding oil.

For an indoor electric fryer, use the oil level specified for that model and never exceed the maximum fill line inside the appliance. There is no universal gallon amount that works for every fryer and turkey.

Never pour water onto burning oil. If a fire starts, move away and call emergency services; shut off the fuel only if you can do so without approaching the flames.

Step 4: Dry the Turkey Thoroughly

Inspect the cavities and joints again for ice.
Pat the outside, both cavities, and any folds of skin dry with paper towels.
Leave the cavities empty, do not deep-fry a stuffed turkey.

Drying is especially important after a water-displacement test. Water trapped inside the cavity can enter the hot oil when the bird is lowered, even when the skin looks dry.

Keep the turkey refrigerated while completing other preparations. Do not leave it on the counter to “come to room temperature.”

Step 5: Preheat the Oil and Lower the Turkey

Preheat the oil to the temperature required by the selected cooking method.
Prepare the basket or lifting assembly.
Lower the turkey slowly, using the fryer’s supplied equipment and heat-resistant gloves.

For Butterball’s indoor method, place the empty basket in the heated oil for 30 seconds, then remove it and load the turkey. Handle the hot basket with the designated lifting tool.

For an outdoor propane fryer, turn the burner off before lowering the turkey into the oil. Lower it slowly to control bubbling and splashing, then turn the burner back on once the bird is safely in place.

Monitor the oil with an appropriate thermometer or the appliance’s temperature control.

Step 6: Set the Timer and Check Several Parts of the Bird

Start timing when the turkey is fully lowered into the oil.
Use the cooking-time estimate to schedule your first doneness check.

For a Butterball turkey, the frying estimate is 3 to 4 minutes per pound. The calculation is:

20 pounds × 3 to 4 minutes per pound = 60 to 80 minutes.

For a method that calls for 3 to 5 minutes per pound, allow 60 to 100 minutes for this weight. Use the timing that accompanies your chosen method, but do not keep frying a turkey that has already reached its required internal temperatures.

At the early end of the estimate, turn off an outdoor burner before lifting the turkey. Let excess oil drain back into the pot, then support the bird securely in a heat-safe pan for temperature checks.

Insert a meat thermometer into the thickest part of each breast and the innermost thigh and wing areas, avoiding bone. For a Butterball turkey, the Butterball deep-frying targets are 170°F for dark meat and 165°F to 170°F for white meat. The general food-safety minimum for turkey is 165°F throughout; Butterball’s higher dark-meat target is its cooking recommendation.

Check both sides of a large bird.

If any area is below the applicable target, carefully return the turkey to the oil, with an outdoor burner off during lowering, then resume cooking and check again. For separated portions, check each piece individually rather than applying the whole bird’s total cooking time to every batch.

Step 7: Drain, Rest, and Carve

Turn off the heat before removing the finished turkey.
Lift it slowly and let excess oil drain back into the fryer.
Set the turkey, still supported by its rack or basket, in a sturdy pan.

Let the turkey stand for 20 minutes before removing it from the rack or basket and carving.

Once rested, transfer it to a clean carving board. Use clean utensils rather than equipment that contacted the raw bird.

Keep the fryer secure while the oil cools completely. Do not move a pot of hot oil or attempt to drain it immediately after cooking.

Why Your Turkey May Take Longer to Fry

Slow Oil-Temperature Recovery

Adding a large, cold turkey lowers the oil temperature. Fryer heating capacity, outdoor conditions, and the amount of food in the oil affect how quickly it recovers.

That recovery affects the cooking estimate, but it does not erase the cooking that has already occurred. Do not restart the clock simply because the oil has returned to its intended temperature.

Keep monitoring the oil as it recovers. Do not try to compensate for poor heating by exceeding the appliance’s operating limits.

Turkey Fried in Separate Portions

Separated breasts, legs, and thighs have different thicknesses and may finish at different times. Batch size and the number of batches also affect the overall schedule.

The whole-bird minutes-per-pound calculation does not reliably predict the total time for a collection of portions. Smaller pieces can badly overcook before thicker pieces finish.

Brown Skin Before the Center Is Ready

Skin color is not a dependable doneness test. Seasoning, surface moisture, and oil temperature can change browning without telling you what is happening in the thickest meat.

The deciding evidence is a set of properly taken internal-temperature readings.

How to Confirm the Turkey Is Ready to Serve

Before carving, make this final check:

Multiple readings passed: Both breasts and the dark-meat areas were checked, with the thermometer tip in meat rather than against bone.
The last check followed the last frying period: If the turkey went back into the oil, it was checked again afterward.
Resting is complete: The turkey has drained and stood before being removed from its support.
The serving area is clean: The carving board, pan, and utensils have not been contaminated by raw turkey.
The fryer is secured: The heat is off, and the cooling oil is protected from people, pets, and accidental contact.

When those checks are complete, carve the turkey on a clean board and serve.

Frequently Asked Questions

What Type of Oil Is Best for Deep-Frying Turkey?

Refined peanut oil is a common choice because it tolerates frying heat and has a relatively neutral flavor. Refined canola oil is another option when permitted by the fryer manufacturer. Choose an oil intended for high-temperature frying, and consider guests’ allergies when selecting it.

How Should I Season a Turkey for Deep-Frying?

Use a dry seasoning blend on the thoroughly dried turkey before frying; black pepper, garlic powder, paprika, and dried herbs are straightforward choices. Add salt according to whether the turkey is already brined, injected, or labeled as containing a seasoning solution. Avoid leaving pools of marinade or other liquid on the bird or inside its cavities.

Can I Deep-Fry a Wild Turkey?

Yes, provided it has been properly handled, is fully thawed and dry, and fits within the fryer’s rated capacity. Use its dressed weight, not its live weight, for planning, and verify that all parts reach at least 165°F with a meat thermometer. Wild turkey is lean, so do not extend cooking merely to darken the skin.

How long does it take to deep-fry a 20-pound turkey?

In a fryer that holds a whole 20-pound bird, plan for about 60 to 80 minutes, using the 3-to-4-minutes-per-pound guideline. Verify doneness with a meat thermometer instead of relying on the timer alone; the turkey needs to reach at least 165°F internally.

Can you deep-fry a Butterball turkey?

Yes, you can deep-fry a Butterball turkey once it has thawed completely, or when starting with a fresh bird. Remove the neck and giblets, then dry the turkey before lowering it into the oil.

Is a 20-pound turkey too big to fry, and what fryer capacity do you need?

No, provided you use a fryer rated to hold a whole 20-pound turkey; a cited extra-large fryer has that capacity. Follow your appliance instructions and do not fill oil above the maximum line.

Should the lid stay on while you deep-fry a turkey?

Yes, for the cited electric-fryer method. In the cited electric-fryer method, the lid remains closed during preheating and is closed again after the turkey is lowered into the oil.

Can you deep-fry a turkey at 300°F?

No, not under the cited methods, which call for oil preheated to 350°F or 375°F rather than 300°F. Monitor the oil with an appropriate thermometer or the appliance’s temperature control.
