How Long to Smoke Pork Belly
Crispy, smoky, melt-in-your-mouth perfection.
Smoked pork belly is the secret weapon of BBQ — the same cut as bacon, but smoked whole and sliced or cubed into burnt ends. A 5–8 lb pork belly slab takes 4–5 hours at 250°F to reach 165°F for slicing, or 6–7 hours total if making burnt ends. The fat renders into something extraordinary. Use our calculator for a precise schedule.
Step-by-Step Cook Schedule
Score the fat cap in a 1-inch crosshatch pattern (don't cut into the meat). Apply a sweet rub generously on all sides — brown sugar, paprika, garlic powder, salt, pepper. Refrigerate overnight uncovered.
Smoke fat-side up at 250°F. The fat will slowly render and baste the meat. No spritzing needed — the fat does the work.
For burnt ends: cube into 1.5-inch pieces, toss in BBQ sauce and honey, return to smoker uncovered for 1.5–2 hours until caramelized and sticky. For sliced pork belly: skip this step and rest after reaching 165°F.
Rest 15 minutes. Serve burnt ends as an appetizer or main. Sliced pork belly is excellent in tacos, ramen, or as a BBQ plate centerpiece.
Pitmaster Tips
Scoring the fat cap is essential — it allows the rub to penetrate and the fat to render evenly.
Apple and cherry wood give a sweet smoke that pairs perfectly with the pork belly's richness.
For burnt ends, use a sweeter BBQ sauce — the caramelized sugar creates that sticky, lacquered exterior.
Pork belly is very forgiving — the high fat content prevents it from drying out even if slightly overcooked.
Skin-on pork belly can be used for crackling — score the skin, rub with salt, and smoke at 275°F for the last hour.

Frequently Asked Questions
How long does it take to smoke pork belly?
A 5–8 lb pork belly slab takes 4–5 hours at 250°F to reach 165°F for slicing. For pork belly burnt ends, add another 1.5–2 hours after cubing and saucing, for a total of 6–7 hours. Thinner slabs (under 3 inches) cook faster.
What temperature should smoked pork belly be?
For sliced pork belly: 165°F internal temperature. For burnt ends (cubed and sauced): the final internal temp is less critical — you're looking for caramelization and a sticky exterior, which happens after 1.5–2 hours back on the smoker after cubing.
What is the difference between pork belly and bacon?
Pork belly is the raw, uncured cut. Bacon is pork belly that has been cured (with salt and nitrates) and smoked. When you smoke a whole pork belly without curing it first, you get something closer to a rich, smoky roast pork — not bacon, but equally delicious.
What wood is best for smoking pork belly?
Apple and cherry are the top choices — they give a sweet, mild smoke that complements the richness of pork belly without overpowering it. Maple is also excellent for a slightly sweeter profile. Avoid heavy woods like hickory or mesquite which can make pork belly taste bitter.
