Prep the pork: Pat the pork shoulder dry.
In a small bowl, combine salt, pepper, smoked paprika, garlic powder, onion powder, chili powder, and cumin. Rub the spice mix all over the pork, pressing to help it stick.
Optional sear: Heat avocado oil in a large skillet over medium-high. Sear the pork 2–3 minutes per side until browned.
This adds flavor, but you can skip this step if you’re short on time.
Mix the sauce: In a bowl, whisk together apple cider vinegar, broth, tomato paste, sugar-free ketchup, Worcestershire sauce (or coconut aminos), keto sweetener, and liquid smoke. Taste and adjust sweetness and tang as needed.
Load the slow cooker: Place the pork in the slow cooker. Pour the sauce over the top, coating the meat evenly.
Cook low and slow: Cover and cook on Low for 8–10 hours or on High for 4–5 hours, until the pork is fork-tender and shreds easily.
Shred and reduce: Transfer the pork to a large bowl and shred with two forks.
Skim excess fat from the cooking liquid. If you prefer a thicker sauce, pour the liquid into a saucepan and simmer 5–10 minutes to reduce slightly.
Toss with sauce: Return the shredded pork to the slow cooker or a large pot. Add enough sauce to coat generously.
Taste and adjust salt, pepper, or sweetness.
Serve: Enjoy on low-carb buns, chaffles, lettuce cups, or over cauliflower rice. Garnish with sliced pickles, red onion, or a dollop of no-sugar-added coleslaw.
