Pork Shoulder (Oven)
at 325°F
The answer
5 hr 50 min – 7 hr 35 minat 325°F
Plan on 50 to 65 minutes per pound in a 325°F oven. A 7 lb pork shoulder (oven) lands around 5 hr 50 min – 7 hr 35 min. Done is 145°F on a food thermometer, plus a 30-minute rest — never the clock alone.

USDA safe zone — 145°F and above
Done is a temperature, not a time. Every figure on this page is a planning range; the green band is the only part that decides. For a pork shoulder in the oven it opens at 145°F and a 30-minute rest.

How this is worked out
- Anchor. Start from what USDA FSIS publishes for a pork shoulder in the oven — its safe minimum internal temperature of 145°F, and the FSIS roasting timetable where one exists for this cut.
- Rate. Convert the anchor into a planning rate at 325°F: 50–65 min/lb, cross-checked against at least three independently published sources.
- Scale. Multiply that rate by your weight. A 7 lb piece lands at 5 hr 50 min – 7 hr 35 min; the range is widened to cover source disagreement rather than averaged into false precision.
- First check. The first thermometer reading is set at 85% of the low end of the range — early enough that an under-reading costs nothing and a late one cannot cost the meal.
- Gate. The time is only a plan. It is not done until a food thermometer reads 145°F in the thickest part, then rests about 30 minutes. Time never overrides temperature on this site.
- Round. Every printed figure is rounded to the nearest 5 minutes; precision beyond that would be invented.
plan_low = weight_lb × 50 min/lb
plan_high = weight_lb × 65 min/lb
first_check = plan_low × 0.85
DONE ⟺ internal_temp ≥ 145°F AND rest ≥ 30 min
(USDA FSIS — the gate, not the clock)

Time by weight at 325°F
Planning ranges for a fully thawed, fridge-temperature pork shoulder (oven). The right-hand column is when to take the first thermometer reading.
| Weight | Estimated time at 325°F | Check thermometer from |
|---|---|---|
| 4 lb | 3 hr 20 min – 4 hr 20 min | 2 hr 50 min in |
| 5 lb | 4 hr 10 min – 5 hr 25 min | 3 hr 35 min in |
| 6 lb | 5 hr – 6 hr 30 min | 4 hr 15 min in |
| 7 lb | 5 hr 50 min – 7 hr 35 min | 5 hr in |
| 8 lb | 6 hr 40 min – 8 hr 40 min | 5 hr 40 min in |
| 9 lb | 7 hr 30 min – 9 hr 45 min | 6 hr 25 min in |
| 10 lb | 8 hr 20 min – 10 hr 50 min | 7 hr 5 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 145°F on a food thermometer (see the pull-temperature note below).

When it is actually done
145°F internal
The USDA FSIS safe minimum internal temperature for this cut is 145°F, followed by a rest of about 30 minutes. The clock estimates; the thermometer decides. Every time on this page is a planning range, not a doneness test.
Pull temperature vs safe temperature: For sliceable roast pork, cook to 145°F and rest. For pulled pork, keep going to 195–205°F — the shoulder's collagen only surrenders up there. The two targets are different dishes from the same cut.

The clock tells you when to start looking. The thermometer tells you when to stop.
What the ledger does not tell you
- Boston butt (the upper shoulder) is the standard choice; picnic shoulder runs a little leaner and faster.
- These are pulled-pork times. If you only want sliceable roast pork to 145°F, expect roughly half the time at the same temperature.
- Bone-in takes slightly longer but the bone sliding out clean is the classic doneness tell.
- The stall applies here just as it does to brisket — wrap in foil at ~160°F to push through it.
Answers people ask
How long does a pork shoulder in the oven take at 325°F?
Plan on 50 to 65 minutes per pound at 325°F. A 7 lb example takes about 5 hr 50 min – 7 hr 35 min. It is done when the internal temperature reaches 145°F on a food thermometer, not when the clock runs out.
What internal temperature is a pork shoulder in the oven done at?
145°F, measured with a food thermometer in the thickest part, then rested about 30 minutes. That is the USDA FSIS safe minimum. For sliceable roast pork, cook to 145°F and rest. For pulled pork, keep going to 195–205°F — the shoulder's collagen only surrenders up there. The two targets are different dishes from the same cut.
Is 325°F a good temperature for a pork shoulder in the oven?
It is one of 4 temperatures this site publishes for this cut (275°F, 300°F, 325°F, 350°F). Lower runs longer and more forgiving; higher runs faster with more browning. 300°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.
