Do I need to sear the pork shoulder first?
No. The slow cooker will still give you tender, flavorful meat. That said, searing can add extra depth. If you want that, do a quick 3 to 4 minute sear per side in a hot skillet before it goes into the crock pot. Most nights, I skip it and use the broiler crisp step at the end instead.
How long should I cook pork shoulder in the crock pot?
For a 4 to 5 pound pork shoulder: 8 to 10 hours on LOW or 5 to 7 hours on HIGH. It is done when it shreds easily with a fork and the thickest part is around 195°F to 205°F (for that melt-in-your-mouth texture). Slow cookers vary, so start checking on the early side if your unit runs hot, the roast is thinner/flattened, or it is boneless.
Quick clarity note: pork is considered safe at 145°F, but it will not shred well there. The higher 195°F to 205°F range is the magic zone for texture.
Is pork shoulder the same as pork butt?
They are close cousins and both work here. Pork butt (Boston butt) actually comes from the shoulder area and is usually a bit more marbled. Either one will shred great.
Should the pork be covered in liquid?
Nope. You want some liquid in the bottom for steam and flavor, but you are going for a gentle moist-cook (think braise-meets-steam), not a boil. Aim for roughly 1/2 to 1 inch of liquid in the bottom. The pork will release a lot of juices as it cooks.
Why is my pork shoulder tough?
It usually needs more time. Tough means the connective tissue has not fully melted yet. Keep cooking on LOW and check again in 30 to 60 minutes.
Can I cook it overnight?
Yes, on LOW. If your slow cooker runs hot, consider a slightly smaller shoulder or start checking closer to the 8 hour mark. Bone-in roasts can take a touch longer; boneless can finish a little sooner depending on thickness.
