A few things worth knowing.
How long does whole chicken take in the oven?
For Whole unstuffed chicken, 3-4 lb, the chart baseline is 1 h 15 min to 1 h 30 min at 350°F. Adjusted sizes and temperatures are modelled estimates.
What makes whole chicken cook faster or slower?
Keep pieces in a single layer; crowded baskets need more time. Thickness, initial temperature and appliance output also matter. A total basket weight does not describe the thickness of each piece.
Can I cook whole chicken from frozen?
The frozen setting gives a starting range. The 50% longer oven estimate is an editorial transfer of USDA frozen-poultry guidance, rather than a food-specific test. Confirm doneness independently; follow package instructions if they differ.
When should I start checking?
Check at 75 minutes for this setting. Keep cooking if the center has not reached the appropriate safety endpoint or texture. A timer is a reminder to check.
How do I know when whole chicken is done?
Check the thickest part, away from bone. Whole birds: also check the inner thigh and wing; stuffing must reach 165°F. A thermometer beats any timer.
