• Preheat your oven to 225 degrees Fahrenheit.
• Position a 3 to 5 pound boneless pork butt roast in a 5 or 7-quart oven-safe pot with a lid, or alternatively, you can use a roasting pan that you will later cover with aluminum foil.
• Rub 2 tablespoons garlic powder, 1 tablespoon salt, and 1 tablespoon black pepper all over the pork roast to coat it evenly. Drizzle 2 tablespoons hickory liquid smoke over the seasoned pork.
• Cover the pot with its lid or tightly cover the roasting pan with aluminum foil. Roast for 8 to 9 hours, until pork shreds easily with a fork. Shred the cooked pork in the pan and mix it well with the juices.
