Why Safe Defrosting Matters

Chicken carries Salmonella and Campylobacter bacteria. The “danger zone” is 5–60°C — in this temperature range, bacteria double roughly every 20 minutes. Defrosting at room temperature puts the outer surface of the chicken in the danger zone for hours while the inside is still frozen. This is how food poisoning happens.

Method 1: Fridge Overnight (Best)

  1. 1

    Transfer to the fridge the night before

    Move frozen chicken from the freezer to the fridge (on a plate or in a container to catch any drips) the night before you plan to cook it. The fridge keeps the chicken below 5°C throughout the thawing process, preventing any bacterial growth. A single chicken breast thaws in 12–16 hours. A whole chicken takes 24–48 hours.

  2. 2

    Use within 1–2 days of thawing

    Once thawed in the fridge, chicken keeps for 1–2 days. Do not refreeze raw chicken that has been thawed in the fridge unless you cook it first.

Method 2: Cold Water (1–3 Hours)

  1. 3

    Seal in a zip-lock bag and submerge in cold water

    Place the chicken in a sealed zip-lock bag (to prevent water contamination and bacterial transfer). Submerge in a bowl of cold tap water. Change the water every 30 minutes to keep it cold. A chicken breast thaws in 1 hour; a whole chicken in 2–3 hours. Cook immediately after thawing — do not refrigerate after cold-water thawing.

Method 3: Microwave (Fastest)

  1. 4

    Use the defrost setting and cook immediately

    Use the microwave’s defrost function (based on weight). The chicken begins to cook in some spots — which is why you must cook it immediately after microwave defrosting. Do not refrigerate microwave-thawed chicken before cooking.

Never defrost chicken on the bench at room temperature. This is the most common cause of chicken-related food poisoning. Even if the chicken feels cold to touch, the surface layer reaches dangerous temperatures quickly. The three methods above are the only safe ways to defrost chicken.

Frequently Asked Questions

Yes — cooking from frozen is safe as long as the chicken reaches an internal temperature of 74°C throughout. It takes approximately 50% longer than cooking from fresh/thawed. Use a meat thermometer to verify. This works well for smaller pieces (chicken breasts, thighs) in the oven or on the stovetop. Stuffed chicken or very large pieces should be thawed first to ensure even cooking.
Only if the chicken was thawed in the fridge and has not been out of the fridge. Refreezing after cold-water or microwave thawing is not recommended. Refreezing after fridge thawing is safe but will reduce the quality (texture and moisture). Cooking the thawed chicken first (then cooling and refreezing the cooked chicken) is a better option if you do not want to use it straight away.
