Smoked Whole Chicken
at 225°F
3 hr 45 min – 5 hr Plan on 45 to 60 minutes per pound in a 225°F smoker. A 5 lb smoked whole chicken lands around 3 hr 45 min – 5 hr. Done is 165°F on a food thermometer, plus a 10-minute rest — never the clock alone.
Time by weight at 225°F
Planning ranges for a fully thawed, fridge-temperature smoked whole chicken. The right-hand column is when to take the first thermometer reading.
| Weight | Estimated time at 225°F | Check thermometer from |
|---|---|---|
| 3 lb | 2 hr 15 min – 3 hr | 1 hr 55 min in |
| 3.5 lb | 2 hr 40 min – 3 hr 30 min | 2 hr 15 min in |
| 4 lb | 3 hr – 4 hr | 2 hr 35 min in |
| 4.5 lb | 3 hr 25 min – 4 hr 30 min | 2 hr 50 min in |
| 5 lb | 3 hr 45 min – 5 hr | 3 hr 10 min in |
| 5.5 lb | 4 hr 10 min – 5 hr 30 min | 3 hr 30 min in |
| 6 lb | 4 hr 30 min – 6 hr | 3 hr 50 min in |
| 6.5 lb | 4 hr 55 min – 6 hr 30 min | 4 hr 10 min in |
| 7 lb | 5 hr 15 min – 7 hr | 4 hr 30 min in |
Start checking the internal temperature well before the low end of the range — an early check costs nothing; a late one costs the meal. Done means 165°F on a food thermometer.
225°F vs the other temperatures
Same cut, every temperature this site publishes for it.
When is it actually done?
165°F internal The USDA FSIS safe minimum internal temperature for this cut is 165°F, followed by a rest of about 10 minutes. The clock estimates; the thermometer decides. Every time on this page is a planning range, not a doneness test.
Worth knowing before you start
- Chicken skin turns rubbery below about 275°F. Many cooks smoke at 250°F then finish the last 15 minutes hot, or simply run the whole cook at 300°F.
- Poultry takes on smoke fast — 45 minutes of smoke is plenty of flavour; the rest of the cook is just heat.
- Spatchcocking (removing the backbone and flattening) cuts these times by roughly a third and evens out breast vs thigh.
Answers people ask
How long does a whole chicken in the smoker take at 225°F?
Plan on 45 to 60 minutes per pound at 225°F. A 5 lb example takes about 3 hr 45 min – 5 hr. It is done when the internal temperature reaches 165°F on a food thermometer, not when the clock runs out.
What internal temperature is a whole chicken in the smoker done at?
165°F, measured with a food thermometer in the thickest part, then rested about 10 minutes. That is the USDA FSIS safe minimum.
Is 225°F a good temperature for a whole chicken in the smoker?
It is one of 4 temperatures this site publishes for this cut (225°F, 250°F, 275°F, 300°F). Lower runs longer and more forgiving; higher runs faster with more browning. 250°F is the most common choice.

Where these numbers come from
Ranges are anchored to USDA FSIS published timetables where they exist, and derived from that anchor plus cross-checked published sources where they do not — widened to cover the disagreement between sources rather than split down the middle. The full reasoning is on the method page. If a figure here looks wrong, say so — corrections are prioritised.
