How Long to Cook Whole Chicken
A whole chicken takes about 20 minutes per pound at 375°F, or roughly 1 hour 20 minutes for a 4 lb bird. Internal temp must reach 165°F in the thickest part of the thigh.
Reference size: per pound (whole bird)
Safe Internal Temperature
165°F / 74°C in the thickest part of the thigh, away from the bone
Cooking Times by Method
| Method | Temperature | Time |
|---|---|---|
| Oven | 375°F / 190°C | 20 minutes per pound + 15 min rest |
| Air Fryer | 360°F / 182°C | 35–45 minutes (3–4 lb bird) |
| Slow Cooker | Low | 6–8 hours |
| Instant Pot | High pressure | 25 minutes + natural release (3–4 lb) |
Oven: Spatchcock (butterfly) the bird to reduce time to 45–50 min total and get crispier skin.
Air Fryer: Only fits smaller birds (up to 4 lb in most air fryers). Spatchcocked works best.
Slow Cooker: Use 3 scrunched-up foil balls to keep chicken elevated off the bottom. Skin won't crisp.
Instant Pot: Add 1 cup broth. Brown first in IP for better flavour.
Chef Tips
- 1Spatchcocking (removing backbone, pressing flat) reduces cooking time by 35% and gives much crispier skin.
- 2Dry brine the night before: rub with salt all over (including under the skin) and refrigerate uncovered overnight.
- 3Stuff aromatics (lemon, garlic, herbs) in the cavity but don't stuff with traditional bread stuffing — it prevents even cooking.
- 4Let rest 10–15 minutes before carving — this is non-negotiable for juicy results.
- 5A 4 lb chicken serves 4 adults with minimal leftovers.
Frequently Asked Questions
How long to cook a 4 lb whole chicken at 375°F?
At 375°F, a 4 lb whole chicken takes approximately 1 hour 20 minutes (20 min per pound). Always verify with a thermometer — 165°F in the thickest part of the thigh away from the bone.
What temperature do I cook a whole chicken?
375°F / 190°C is the standard. For crispier skin and shorter time: 425°F for 15–17 min per pound works brilliantly. Lower temps (325°F) take longer but give juicier meat — personal preference.
How long to cook a whole chicken per pound?
At 375°F: 20 minutes per pound. At 425°F: 15 minutes per pound. Add 15–20 minutes if stuffed. The rule of thumb gets you close but always verify with 165°F internal temp.
How do you know when a whole chicken is done?
The most reliable way: meat thermometer reads 165°F in the thickest part of the inner thigh, not touching bone. Visual signs: juices run clear when thigh is pierced, legs wiggle freely, skin is golden brown.
