How to Cook Chicken: Breast, Thighs and Whole Chicken

Chicken is safe to eat when the thickest part reaches 165°F (74°C). Cooking times change with thickness, oven and pan, so use a meat thermometer rather than relying on time or colour alone. Below are reliable starting points for the most common cuts.

Safe temperature

Cook all chicken to 165°F (74°C), measured in the thickest part and away from the bone. Pink colour is not a reliable test: some fully cooked chicken stays slightly pink, and some pieces turn white before they reach a safe temperature.

These are starting points. Thicker pieces, chicken straight from the fridge and different ovens all change the time. Frozen chicken takes roughly half as long again to cook as fresh chicken. Check the temperature before serving.

Oven-roasted chicken breast

  1. Heat the oven to 425°F (220°C). Line a tray with foil or baking paper.
  2. Pat the chicken dry and season with salt, pepper and a little oil or your favourite spices. Dry skin and surfaces brown better.
  3. Space the pieces apart so they roast rather than steam.
  4. Roast for 18–25 minutes, until the thickest part reaches 165°F (74°C).
  5. Rest for 5 minutes before cutting so the juices stay in the meat.

Pan-seared chicken breast

  1. Pat the chicken dry and season. If the breasts are thick, pound them to an even thickness so they cook through at the same rate.
  2. Heat 1 tablespoon of oil in a heavy pan over medium-high heat.
  3. Cook for 5–7 minutes without moving, until golden underneath. Flip.
  4. Lower the heat to medium, cover and cook for 3–5 minutes more, until 165°F (74°C).
  5. Rest for 5 minutes before slicing.

Whole roast chicken

  1. Heat the oven to 375°F (190°C). Pat the bird dry, season inside and out, and tuck the wings under.
  2. Place it breast-side up on a rack in a roasting tin.
  3. Roast for about 1 hour 15 minutes to 1 hour 30 minutes for a 4 lb (1.8 kg) bird. Check 165°F (74°C) in the thickest part of the thigh and in the breast.
  4. Rest for 15 minutes before carving.

Air fryer thighs

  1. Preheat the air fryer to 380°F (195°C).
  2. Season the thighs and arrange them in a single layer, leaving space between pieces.
  3. Cook for 15–20 minutes, flipping halfway, until 165°F (74°C).

Food safety tips

Cooking chicken in a 1,500-calorie plan

Skinless chicken breast is lean and high in protein, so it fits well into a calorie-controlled week. Removing the skin before cooking and measuring oil with a spoon keeps the calories predictable.

Frequently asked questions

How long does it take to cook chicken breast?

A boneless, skinless breast usually takes 18 to 25 minutes at 425°F (220°C), depending on thickness. Use a thermometer to confirm 165°F (74°C).

Can you cook chicken from frozen?

Yes, but it takes about half as long again as fresh chicken. Cook until the thickest part reaches 165°F (74°C). Thawing in the fridge gives more even results.

Is chicken done when the juices run clear?

Clear juices are not a reliable sign. A reading of 165°F (74°C) on a thermometer is the safe check.
