Pulled pork is perfect for the slow cooker. Cooking the pork low and very slow is the secret to the juiciest and most tender pulled pork. This is a base recipe and while it is delicious as-is, you should feel free to stir in your favorite barbecue or other sauces at the end of cooking.
1 (4 1/2 to 5 pound) boneless or bone-in pork shoulder (also known as pork butt), twine or netting removed
2 teaspoons salt, plus more as needed
1 teaspoon fresh ground black pepper
2 tablespoons neutral flavored oil
1 medium onion, peeled and chopped small
4 cloves garlic, peeled and minced
2 tablespoons tomato paste
1 tablespoon ancho or mild chili powder, see our homemade chili powder recipe
2 teaspoons ground cumin
3 tablespoons apple cider vinegar
1 tablespoon fish sauce or 1 tablespoon Worcestershire sauce
1 cup water
Rub the pork with salt and pepper, and then set aside while you prepare the remaining ingredients.
Heat oil in a wide skillet over medium heat. Add the onions and garlic then cook, stirring occasionally, until they are sweet and browned around the edges. Stir in the tomato paste, chili powder, and cumin. Cook, stirring often, until the tomato paste turns from bright red to orange in color; about 3 minutes. Add the water, apple cider vinegar, and fish sauce and cook for about 1 minute, scraping up the browned bits on the bottom of the pan.
Rest the seasoned pork in the bottom of a slow cooker then pour the onion and spice mixture on top. Wiggle the pork around the bottom of the slow cooker so that some of the onion and spice mixture slides underneath. Cover with lid and cook on low for 8 to 10 hours, or until the pork can be easily shredded.
Turn off the slow cooker and transfer the pork to a cutting board. If the pork has a bone in it, remove and discard it. Use two forks to shred the meat, discarding any connective tissue, and large clumps of fat.
Remove the cooking liquid and skim most of the fat from its surface. Discard the fat then set the cooking liquid aside.
If using barbecue sauce, add it to the slow cooker and stir in the shredded pork. If the mixture needs to be thinned out a little, add back some of the reserved cooking liquid. If you’re not using barbecue sauce, add the shredded pork back to the slow cooker and stir in enough cooking liquid so that the pork is moistened. Taste and season with salt, additional vinegar, or hot sauce as needed.
