How long does pork shoulder take to slow roast?

Pork shoulder (also called pork butt or Boston butt — confusingly, both come from the shoulder, not the butt) is a tough cut requiring long, low cooking to break down collagen into gelatin.

Internal temperature is the truth, not time. Pork shoulder is done not by time but by internal temp: - 145°F = safe to eat but tough (sliceable, not shreddable) - 165°F = passes USDA but still chewy - 185°F = collagen starting to break down - 195–205°F = "probe-tender" — meat slides off bone, shreds with forks (target for pulled pork) - 205°F+ = fully rendered, fall-apart tender (don't exceed 210°F or dries out)

Time estimates by temperature (5 lb shoulder):

• 225°F (low and slow, classic BBQ): 8–10 hours
• 250°F (smoker standard): 6–8 hours
• 275°F (faster but still tender): 5–6 hours
• 325°F (Dutch oven oven roast): 4–5 hours
• Higher than 350°F: 2.5–3.5 hours but tougher result

The "stall": Around 165°F, pork shoulder may sit at the same temperature for 1–3 hours (called "the stall" — moisture evaporating from surface absorbs heat). This is normal. Wrap in foil ("the Texas crutch") to push through faster if needed.

Method options: - Smoker: classic BBQ method, 6–10 hours, wood smoke flavor - Dutch oven (oven 300°F): 4–5 hours, indoor-friendly, excellent results - Slow cooker on low: 8–10 hours - Instant Pot pressure cook: 90 min + 30 min natural release (different texture but very tender) - Sous vide 165°F for 24 hours, then sear: best texture, most consistent

Rest the meat 30–60 minutes after cooking (gelatin redistributes). Then shred with two forks. Save the drippings — incorporate back into the meat for moisture.
