Cooking Methods
🔥 Oven
Temperature: 275°F
Rest: 30 minutes
Low and slow until internal temp reaches 195-205°F and a fork twists easily in the meat. The collagen needs to fully break down.

🥘 Slow Cooker
Time: 480–600 minutes
On low for 8-10 hours with 1/2 cup liquid. Shred with two forks when done.
⚡ Instant Pot / Pressure Cooker
Pressure: High
Time: 60–90 minutes
Release: Natural release 15 minutes
Cut shoulder into 3-4 large chunks for faster cooking. Add 1 cup liquid (broth, apple cider, or cola). About 15 minutes per pound. Shred with forks after cooking.
The USDA safe temp for pork is 145°F, but pulled pork needs 195-205°F. That extra heat is what breaks down the collagen into gelatin and makes it shreddable. At 145°F it would be a roast, not pulled pork.
Frequently Asked Questions
Food safety and texture are different goals. 145°F makes pork safe to eat. 195-205°F breaks down the tough connective tissue into tender, shreddable gelatin. Both temperatures are safe; only one makes pulled pork.
The Bottom Line
Pulled Pork is straightforward to cook when you know the time and temperature. The most important number to remember is 145°F internal. An instant-read thermometer is the only reliable way to confirm doneness; color and firmness are not accurate indicators. Use the method that fits your equipment and schedule, and always let the food rest before cutting or serving. Resting allows juices to redistribute and carryover cooking to finish the job.
