Pork Belly Smoking Time Calculator

Smoked pork belly burnt ends with sticky glaze

Pork belly is one of the richest, most indulgent cuts you can put on a smoker. Whether you smoke it as a whole slab for slicing or cube it into burnt ends, the result is deeply savory, melt-in-your-mouth meat with crackling edges. A 5-pound slab takes about 5 hours at 225F. Pork belly burnt ends, cubed and sauced, require a two-stage cook: smoke the cubes for 2 hours, then toss in sauce and smoke for another hour until the glaze sets and the edges caramelize. Our calculator handles both styles. The whole slab method produces slices that work beautifully in sandwiches, ramen, or as a standalone entree. The burnt ends method creates bite-sized, candy-like pieces that disappear from the plate within minutes. Both versions benefit from a dry rub with brown sugar and a moderate smoker temperature.

Calculator

How It Works

Enter the weight of your pork belly slab. For whole slab smoking, the rate is approximately 60 minutes per pound at 225F. The target internal temperature is 200F, where the fat has fully rendered and the connective tissue has broken down. For burnt ends, cube the raw belly into 1.5-inch pieces, smoke for 2 hours, toss in sauce and butter in a foil pan, then smoke covered for 1 hour, then uncovered for 30 minutes to set the glaze. The calculator outputs timing for both methods.

Frequently Asked Questions

What temperature for pork belly?
Smoke pork belly at 225-250F for the best texture. The target internal temperature is 195-200F for a whole slab, at which point the fat is fully rendered and the meat is tender. For burnt ends, the two-stage process handles temperature differently: the initial smoke brings cubes to about 165F, then the braised and glazed phase pushes them to 200F+.
How do I make pork belly burnt ends?
Cut the raw belly into 1.5-inch cubes. Season with your rub and smoke at 250F for 2 hours on a wire rack. Transfer the cubes to a foil pan, toss with BBQ sauce, honey, and a tablespoon of butter. Cover the pan with foil and return to the smoker for 1 hour. Remove the foil and smoke for 30 more minutes until the glaze is sticky and caramelized.
How long does pork belly take at 225?
A whole pork belly slab takes approximately 60 minutes per pound at 225F. A 5-pound slab cooks in about 5 hours plus 20 minutes of rest. Burnt ends take approximately 3.5 hours total regardless of quantity: 2 hours initial smoke, 1 hour covered, 30 minutes uncovered.
What rub for pork belly?
A rub with brown sugar as the base works well with pork belly. The sugar caramelizes during the cook and creates a sweet-savory bark. Add kosher salt, black pepper, garlic powder, paprika, and a touch of cayenne. For burnt ends, the sauce glaze in the second phase adds another layer of flavor, so keep the initial rub relatively simple.
Can I slice smoked pork belly thin?
Yes. After smoking and resting, refrigerate the whole slab for several hours until firm. Use a sharp knife or meat slicer to cut thin slices. These can be crisped in a hot pan for a few seconds per side, similar to thick-cut bacon. Smoked and sliced pork belly is excellent in sandwiches, on ramen, or as a topping for rice bowls.
