Pork Shoulder (Oven)
cooking times
The answer
7 hr – 8 hr 45 minat 300°F
At the most common temperature, 300°F, a pork shoulder in the oven runs about 7 hr – 8 hr 45 min at 7 lb. Pick your temperature below for the full chart. Done is always 145°F internal.

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 300°F: 60–75 min/lb, cross-checked against at least three independently published sources.
- Scale. Multiply that rate by your weight. A 7 lb piece lands at 7 hr – 8 hr 45 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 × 60 min/lb
plan_high = weight_lb × 75 min/lb
first_check = plan_low × 0.85
DONE ⟺ internal_temp ≥ 145°F AND rest ≥ 30 min
(USDA FSIS — the gate, not the clock)

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.

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.
The clock tells you when to start looking. The thermometer tells you when to stop.
