How Long Does It Take to Defrost a Turkey?

Quick Answer

Defrosting a turkey in the refrigerator takes 24 hours for every 4–5 pounds. A 15-pound turkey needs 3–4 days in the fridge. The cold water method is faster at 30 minutes per pound but requires constant attention. Microwave thawing works for smaller birds but produces uneven results.

Refrigerator Thawing Times by Weight

This is the safest and recommended method. Place the turkey breast-side up in its original wrapper on a tray in the refrigerator (40°F or below).

Turkey Weight	Refrigerator Time	Start Thawing
4–8 lbs	1–2 days	2 days before cooking
8–12 lbs	2–3 days	3 days before cooking
12–16 lbs	3–4 days	4 days before cooking
16–20 lbs	4–5 days	5 days before cooking
20–24 lbs	5–6 days	6 days before cooking

A thawed turkey can safely remain in the refrigerator for 1–2 additional days before cooking.

Cold Water Thawing Times by Weight

Submerge the wrapped turkey in cold water (below 40°F). Change the water every 30 minutes. Cook the turkey immediately after thawing.

Turkey Weight	Cold Water Time	Water Changes Needed
4–8 lbs	2–4 hours	4–8
8–12 lbs	4–6 hours	8–12
12–16 lbs	6–8 hours	12–16
16–20 lbs	8–10 hours	16–20
20–24 lbs	10–12 hours	20–24

Microwave Thawing

Use the defrost setting based on your turkey's weight. Check your microwave's manual for specific power settings and times.

Turkey Weight	Approximate Time	Notes
4–8 lbs	30–60 minutes	Only method suitable for this size
8–12 lbs	60–90 minutes	May not fit in all microwaves
12+ lbs	Not recommended	Too large for most microwaves

Microwave thawing produces uneven results — some parts may begin to cook while others remain frozen. Cook the turkey immediately after microwave thawing.

Step-by-Step: Refrigerator Method

1. Check the weight on the packaging to calculate thawing time
2. Keep the turkey in its original wrapper to prevent cross-contamination
3. Place breast-side up on a rimmed baking sheet or roasting pan to catch any drips
4. Set on the lowest refrigerator shelf to prevent dripping onto other food
5. Allow 24 hours per 4–5 pounds — count backward from your planned cooking day
6. Check that the cavity is thawed by reaching inside — ice crystals mean more time needed
7. Remove giblets from the cavity once fully thawed

Step-by-Step: Cold Water Method

1. Ensure the turkey is in a leak-proof wrapper — double-bag if needed
2. Submerge in cold tap water in a large pot, cooler, or clean sink
3. Change the water every 30 minutes — this keeps the surface temperature safe
4. Allow 30 minutes per pound of turkey
5. Cook immediately after thawing — do not refrigerate and cook later

Food Safety Rules

Rule	Details
Never thaw at room temperature	Bacteria multiply rapidly between 40°F–140°F
Never thaw in hot water	Outer layers reach unsafe temperatures
Cook immediately after cold water or microwave thawing	Refrigerator-thawed turkey can wait 1–2 days
Internal temperature must reach 165°F	Check the thickest part of the thigh
Wash hands after handling raw turkey	Avoid rinsing the turkey — it spreads bacteria

Forgot to Thaw? Emergency Options

• Cook from frozen — It is safe to cook a frozen turkey. Add 50% more cooking time (a 4-hour turkey becomes a 6-hour turkey). The USDA confirms this is safe.
• Cold water express — Start the cold water method immediately. Even partial thawing helps reduce cooking time.
• Spatchcock (butterfly) a partially thawed turkey — it cooks faster and more evenly at 450°F for about 80 minutes for a 12–14 lb bird.
