Before you start
Before you start, take the pork shoulder out of the refrigerator and let it sit at room temperature for up to 30 minutes—this helps it cook more evenly. Meanwhile, smash the garlic cloves by pressing them with the flat side of a knife; this releases their flavor without mincing.
Rinse the rosemary and thyme sprigs and pat them dry. Measure the butter and have it ready. Place the slow cooker on the counter and plug it in, so it's preheating while you assemble the ingredients.

Instructions
Assemble and Start
- Layer the Roast and AromaticsPlace the pork shoulder roast in the center of the slow cooker. Scatter the smashed garlic cloves over the top, then lay the fresh rosemary and thyme sprigs over the roast. The herbs will perfume the meat as it cooks.Look for The roast sits snugly in the slow cooker with garlic and herbs scattered across the top.Tip Tuck the herb sprigs under any strings or netting if present, so they stay in contact with the meat.
- Add the ButterPlace the whole stick of salted butter on top of the seasoned roast. It will melt as the slow cooker heats, basting the meat and blending with the juices to create a rich sauce.Look for The butter sits proudly on the roast, ready to melt into the meat.Tip Cut the butter into a few pieces if you prefer it to melt faster, though a whole stick works perfectly.
At this point, the slow cooker contains a raw pork roast topped with garlic, herbs, and butter. The aromatics are fresh and fragrant, and the butter is cold. The scene looks simple but promising. Before moving on, ensure the roast is centered and the herbs are well distributed, so they flavor the meat evenly as it cooks.
Slow Cook
- Cook Low and SlowCover the slow cooker and cook on low for 8 hours, or on high for 5-6 hours, until the pork is fork-tender and easily shreds. The internal temperature should reach at least 145°F (63°C) for food safety, but the meat will be most tender at 195-205°F (91-96°C). Let it rest for 3 minutes before slicing.Look for The pork is deeply browned and the juices are bubbling around the edges.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Resist the urge to lift the lid; each peek adds 20 minutes of cooking time.
After several hours, the slow cooker is filled with bubbling juices. The butter has melted, creating a golden emulsion with the pork's natural drippings. The room smells of garlic and herbs.
The meat is visibly shrinking and pulling away from the bone (if bone-in). A gentle poke with a fork shows it's becoming tender. The liquid is savory and rich—resist the urge to taste too much!
Shred and Finish
- Shred and ServeRemove the herb sprigs and any large garlic cloves (they will be soft and can be mashed into the sauce). Transfer the pork to a cutting board and shred with two forks. Return the shredded meat to the slow cooker and toss with the pan juices. Serve hot, spooning extra jus over the top.Look for The pork pulls apart easily and is coated in glossy, buttery juices.Tip For extra flavor, let the shredded pork sit in the juices for 10 minutes before serving.
The pork is fully cooked and shreds with ease. The meat is coated in a glossy, buttery sauce, and the garlic cloves have become soft and sweet. The herbs have infused the liquid. The final dish looks rustic and inviting, with tender ribbons of pork glistening in the golden jus. Serve immediately, spooning extra sauce over each portion.
Common mistakes
One common mistake is lifting the lid too often to check on the roast. Each time you open the slow cooker, heat escapes, adding significant time to the cooking process. Trust the recipe and keep the lid on.
Another pitfall is using a lean cut like pork loin, which will dry out during long cooking. Stick with pork shoulder or butt. Finally, don't skip the resting step after shredding—letting the meat sit in the juices allows it to reabsorb moisture and flavor.
How to tell it’s done
The pork is done when it is fork-tender and shreds easily with little resistance. The internal temperature should read at least 145°F (63°C) for safety, but for the most tender, pull-apart texture, aim for 195-205°F (91-96°C).
At this temperature, the collagen has fully broken down into gelatin, leaving the meat succulent and easy to shred. If the meat still feels tough, continue cooking and check again after 30 minutes.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
