Season the Pork. Start by seasoning your pork shoulder with the paprika, cumin, onion powder, garlic powder, salt, pepper, and thyme. Rub the spices into the meat to ensure it's evenly coated.
Sear the Pork. Heat olive oil in a large skillet over medium-high heat. Once the oil is hot, sear the pork on all sides for about 3-4 minutes per side until it’s golden brown. This step will add extra flavor to the pork.
Slow Cook the Pork. Transfer the seared pork shoulder to a crockpot. Add the sliced onions, minced garlic, and chicken broth. Cover and cook on low for 6-8 hours, or on high for 4-5 hours, until the pork is tender and easily pulls apart with a fork.
Make the BBQ Sauce. While the pork is cooking, combine all of the BBQ sauce ingredients in a small saucepan over medium heat. Stir occasionally until the sauce is heated through and the sugar has dissolved, about 5 minutes. Taste and adjust the seasoning if necessary.
Shred the Pork. Once the pork is tender, remove it from the crockpot and place it on a cutting board. Use two forks to shred the meat, discarding any large pieces of fat. Return the shredded pork to the crockpot and mix it with the juices and onions.
Assemble the Sliders. Split the slider buns and lightly toast them if desired. Spoon the pulled pork onto the bottom half of each bun. Top with a spoonful of the homemade BBQ sauce, and add any additional toppings you like, such as pickles or coleslaw. Place the top half of the bun on and serve immediately.
