Ingredients

8–10 lb (3.6–4.5 kg) pork shoulder (Boston butt), bone-in or boneless
1–2 tbsp Hawaiian sea salt (alaea salt preferred) or kosher salt, plus extra to taste
2–3 tbsp liquid smoke (kālua flavor) — optional but commonly used for home preparation
4–6 ti leaves or banana leaves (optional, for authentic flavor and wrapping) or large collard leaves
4–6 cups water or chicken broth (960 ml – 1.44 L)
4–6 cloves garlic, smashed (optional)
1–2 tbsp neutral oil (if searing first) — optional
Butcher twine (if trussing)
Heavy-duty aluminum foil (for oven method) or a roasting pan with lid
For traditional imu method only: hot volcanic rocks, dry kindling, shovels, and enough earth to cover the pit

Instructions

Overview: Kalua pig is traditionally cooked in an underground oven (imu) using hot rocks and ti or banana leaves. The following gives a traditional summary and two home-kitchen methods (oven and slow cooker) that reproduce the smoky, tender result.
Prep the pork: Pat the pork shoulder dry. Rub the meat all over with 1–2 tablespoons of Hawaiian sea salt (use more for a stronger salty profile). Optionally rub smashed garlic over the pork.
If using liquid smoke (home method): Brush or rub 2–3 tablespoons of liquid smoke evenly over the pork to introduce smoky, imu-like aroma.
Wrap in leaves (authentic step, optional for home cooks): Lay 2–3 ti or banana leaves flat (lightly wilt over flame or in oven to make pliable). Place the pork on the leaves and wrap tightly. Tie with butcher twine. If leaves are unavailable, proceed with heavy-duty foil.
Traditional imu method (summary / requires community and safety):
  a. Dig a pit about 2–3 feet deep and wide enough to hold the wrapped pork and hot rocks. Line the bottom with stones.
  b. Build a wood fire on the stones until the rocks are very hot and white from heat; burn down to coals. Remove embers but leave hot rocks in place, or carefully move rocks and set meat on top of the rocks.
  c. Place additional banana/ti leaves over the hot rocks, then set the wrapped pork on top. Cover the pork with more leaves, burlap, and then pack the pit with earth to seal heat and steam in. Cook 6–8 hours for a large shoulder (longer for larger pieces) until meat is fall-apart tender.
  d. When done, carefully uncover (steam will be extremely hot), remove meat, shred, and season to taste.
Oven method (recommended for most home cooks):
  a. Preheat oven to 325°F (165°C). Place a rack in a roasting pan or use a deep baking dish.
  b. If you like a browned exterior, sear the pork shoulder in a hot skillet with 1–2 tablespoons oil, browning all sides for 3–4 minutes per side (optional).
  c. Place the wrapped pork (leaf-wrapped) or the pork on a bed of leaves in the roasting pan. Add 1–2 cups water or broth to the bottom of the pan for moisture. If not using leaves, wrap the pork tightly in heavy-duty foil, adding 1–2 tablespoons liquid smoke under the foil if desired.
  d. Cover tightly with lid or additional foil. Roast at 325°F (165°C) for 4–6 hours for 8–10 lb, or until internal temperature is 195–205°F (90–96°C) and the meat shreds easily. Check after 3–4 hours and add more liquid if pan is dry.
  e. Remove from oven, unwrap carefully to avoid steam, and transfer to a cutting board. Let rest 15–20 minutes, then shred the meat with two forks or meat claws. Mix in pan juices and additional salt to taste. If you want a crispier edge, spread shredded pork on a rimmed sheet and bake at 425°F (220°C) for 10–15 minutes, stirring once, to caramelize.
Slow-cooker method (convenient, hands-off):
  a. Season/stuff and optionally sear the pork as above. Place pork in slow cooker, add 1–2 tablespoons liquid smoke (optional), smashed garlic, and 1–2 cups water or broth. If using leaves, wrap the pork in leaves first.
  b. Cook on LOW for 8–10 hours or HIGH for 4–6 hours, until meat is fall-apart tender. Shred and mix with cooking juices. Adjust salt.
Finishing and serving: Shred the pork finely to resemble traditional kalua texture. Taste and add more Hawaiian salt if desired. Serve hot over steamed rice and accompany with lūʻau-style sides such as poi, lomi-lomi salmon, macaroni salad, or steamed cabbage.
Storage and reheating: Cool completely, refrigerate in an airtight container up to 4 days or freeze up to 3 months. Reheat gently in a covered pan with a splash of water or broth, or microwave covered, to restore moisture.
Notes and tips: Authentic kalua pig gets its flavor from the imu—smoky, slightly salty, and steamy. Liquid smoke and banana/ti leaves help approximate that at home. Use alaea (red) salt for the most traditional Hawaiian flavor when available. Always take safety precautions if attempting an imu (community permission, correct ventilation, careful handling of hot rocks and earth).
