Cut skinless pork belly into roughly 1½-inch cubes, season them, and smoke them uncovered at 250°F until the outside has a dark, dry bark. Move the cubes into a covered pan with a modest amount of sauce and a little liquid or fat. Cook until a probe slides into several cubes easily. Uncover, toss, and finish just long enough to make the glaze tacky. That is the whole process: smoke, soften, set.

Plan on roughly four to six hours, but the amount of fat, cube size, weather, cooker, and sauce all change the timing. The smoking calculator can give you a planning window. Your actual stop signals are bark and tenderness. Cook to internal temperature, not to the clock. The meat temperature chart explains the difference between a USDA safety minimum and the much higher texture target for slow-cooked pork.

Pork belly burnt ends are rich. Serve them as a small appetizer, alongside something acidic, or as the flavorful part of a larger plate. Four pounds of raw belly can look like a mountain of cubes, but they shrink substantially as fat renders. Plan portions accordingly with the portion calculator if you are feeding a group.

What makes a burnt end

Traditional brisket burnt ends begin with the point of a smoked brisket. Pork belly burnt ends borrow the small, smoky, sauced format but use a different cut. Belly has alternating bands of fat and meat. When treated patiently, the fat softens, the meat becomes tender, and each cube develops its own seasoned surface. It should feel luscious rather than rubbery or like a spoonful of unmelted fat.

Cubing before smoking creates much more exposed surface than smoking the slab whole. That surface takes seasoning and smoke and gives each piece edges for glaze to cling to. The tradeoff is that small pieces can dry out or scorch if the pit runs too hot. Large pieces protect their centers but take longer to render. Roughly 1½ inches is a practical compromise, also used by ThermoWorks in its pork belly burnt ends method.

These are not bacon unless the belly has been cured. Buy fresh, uncured pork belly. If the package says bacon, the salt, cure, and slicing are already different, so it will not behave like this recipe. Look for a fairly even slab with visible lean streaks between fat layers.

Buy the right belly

Ask for a skinless, uncured slab. A thick central section produces more evenly sized cubes than tapered ends. The fat cap is welcome, but a slab that is nearly all white fat will yield fewer balanced bites. The lower surface often has a firm layer of fat. Trim only hard, waxy patches or ragged edges; leave the soft layers that will render during cooking.

If skin is attached, remove it before cubing. The skin will remain tough in this method. Set the slab skin side down, start at one corner, and angle a sharp knife just above the skin while pulling the skin taut. Work slowly so you keep the meat. If that job feels awkward, ask the butcher to remove it. Save any clean trimmings for another cook, but do not put thin scraps on the grate with the main cubes and expect them to finish together.

Fresh belly is usually sold chilled or frozen. Thaw frozen belly in the refrigerator until you can cut it cleanly. Partly firm belly is easier to cube than a warm, floppy slab, but it should be fully thawed before cooking so the pieces heat evenly. Keep raw pork cold while you prepare the smoker and wash hands and tools after handling it.

Equipment and a balanced ingredient list

For about four pounds of pork belly, gather the following. Quantities are a starting point because surface area and sauce sweetness vary.

• Four pounds fresh, skinless pork belly.
• Two to four tablespoons of a pork barbecue rub, depending on salt content.
• A shallow wire cooling rack that fits your smoker, optional but helpful for moving cubes.
• One large disposable aluminum pan and heavy-duty aluminum foil.
• About ¾ cup of barbecue sauce, plus more only if needed after tasting.
• Two tablespoons of honey, optional for a sweeter finish.
• A splash of apple juice or water if the sauce is very thick.
• An instant-read meat thermometer with a narrow probe.

Use less sugar when the rub is already sweet. Many prepared sauces are sweet enough on their own. A small amount of vinegar at the end can brighten a heavy glaze without turning the pan watery. Apple or cherry pellets give a gentle result; oak or hickory give a firmer smoke note. Our wood pairing guide covers how to choose among them.

The rack prevents cubes from slipping through wide grates. It also lets you lift an entire batch without repeatedly opening the lid. Leave room between pieces so smoke can reach the sides. If the rack is crowded, use two racks or cook in batches rather than piling cubes.

Cut and season consistently

Put the cold slab on a stable board. Cut long strips about 1½ inches wide, then cut across the strips to form cubes. They will not be mathematically perfect because belly thickness changes across the slab. Sort the noticeably smaller pieces into one area of the rack so you can check them early. Keep the fattiest pieces together too; they may need more time to soften.

Dust all sides with rub and toss gently. You want a visible coating, not a thick crust of loose powder. Set the cubes on the rack with a little space between them. Let the seasoning hydrate while the smoker preheats, but keep the tray refrigerated if the cooker needs a long setup. Avoid a sugary binder because it can make the surfaces sticky before they have developed bark.

A simple homemade seasoning is salt, black pepper, paprika, and garlic powder. Use a restrained salt hand if your sauce is salty. Rubs differ widely, so taste the seasoning and sauce separately before combining them on four pounds of meat. You can add salt at the table; you cannot pull it out of a reduced glaze.

Meat Church shows the cube-first approach in the video above. Watch how evenly sized cubes gain seasoning on every face. Their specific sauce choices are optional; the three-stage structure matters more than the brand on a bottle.

Set the smoker for clean heat

Preheat to about 250°F with indirect heat. At 225°F the cook usually takes longer, and at 275°F you need to watch sugar and small pieces more carefully. The goal is a steady environment where the outside dries and browns while fat slowly renders. A pellet grill, offset, charcoal smoker, or kettle with a two-zone setup can all do this. If using a kettle, keep the cubes away from direct heat over the coals.

Place a grate-level thermometer near the tray if your built-in display reads air far above the food. Airflow and heat shielding vary across a cooker. Rotate the tray when one side darkens faster, but avoid opening the lid every ten minutes. That slows bark formation and adds little useful information.

Look for thin, clean smoke rather than thick white clouds. Heavy, stale smoke can turn the sweet fat bitter. Do not block vents in an attempt to trap smoke. On a pellet cooker, use the manufacturer's smoke mode only within its specified temperature range and then return to the main cooking setting. The pellet smoke flavor guide explains that adjustment in detail.

Stage one: build bark without burning

Spread the cubes over the grate or rack and leave them uncovered. Start looking at color after about two hours. The exterior should turn deep mahogany and feel set when touched gently with tongs. If seasoning smears off into the tongs, give it longer. If small pieces look dark and stiff before the rest, move them into the pan early rather than sacrificing them to a fixed schedule.

A little rendering is expected. Fat droplets on the rack are a sign that the process is moving. Puddles of grease under the cubes do not improve flavor, so keep the tray open enough to drain and avoid putting the cubes in a solid pan for the entire first stage. They would steam in their own fat instead of building bark.

Do not judge this stage by internal temperature alone. A 1½-inch cube is hard to probe without touching fat or the tray, and a single reading does not describe its exterior. Color and surface feel are the useful checks. If the pit runs hot, reduce heat instead of adding more sauce to hide scorched edges.

Stage two: soften in a covered pan

Transfer the browned cubes into the aluminum pan. Add a modest layer of sauce, optional honey, and only enough apple juice or water to loosen a very thick mixture. Toss gently until coated. You should still see individual cubes, not a deep pool that completely submerges them. Cover the pan tightly with foil and put it back in the smoker at about 250°F.

Begin checking after roughly 45 to 60 minutes. Lift a foil corner away from your face; trapped steam and hot rendered fat can burn. Probe several meat-heavy cubes from different parts of the pan. The probe should slip in easily, and the fat should feel soft rather than springy. If the center still resists, reseal and cook longer. ThermoWorks also uses a covered-pan tenderizing stage, but feel is more reliable across irregular cubes.

USDA FSIS lists 145°F with a three-minute rest as the safe minimum for whole-muscle pork. Burnt ends continue far beyond that because fat and connective tissue need time to soften. A cube can be safely cooked yet unpleasantly chewy. The site's meat temperature chart keeps safety and preferred barbecue texture separate.

If sauce starts sticking on the bottom, stir carefully and add a tablespoon or two of liquid. If the pan is soupy, leave it uncovered longer in the final stage. More sugar will not solve excess water; evaporation will.

Stage three: set the glaze

Remove the foil and gently turn the pieces in the pan liquid. Cook uncovered until the liquid reduces to a glossy coating that clings to the cubes. This may take 15 to 30 minutes. Stir once or twice, especially around the edges where sugar concentrates. Stop when the glaze is tacky and the pieces are tender. Letting the pan sit in the cooker indefinitely will make the sauce dark and bitter.

Taste one cube after it cools enough to handle. If it needs brightness, add a small splash of cider vinegar and toss. If it needs heat, add a little hot sauce at the table or in the final glaze. If it is too sweet, balance it with acid and salt rather than adding another layer of syrup. A crisp slaw or pickled onion served beside the pork helps the whole plate feel balanced.

Rest the pan briefly, then transfer the cubes to a platter. Spoon over only the sauce that still tastes clean and balanced. Leave any thick layer of rendered grease behind. Burnt ends should be glossy, not swimming.

Timing for a party

Build the schedule backward from serving time. Allow time to trim, cube, preheat, smoke, cover, glaze, and rest, plus a buffer for a stubborn slab. For a typical four-pound batch, reserve most of the day rather than promising an exact dinner minute. If the cubes finish early, keep them hot in a covered pan for a short hold, then refresh the glaze just before serving.

Do not leave cooked pork on a picnic table for the afternoon. USDA FSIS advises refrigerating perishable food within two hours, or one hour above 90°F. Divide leftovers into shallow containers so they cool quickly. When reheating leftovers, USDA FSIS lists 165°F. Warm them covered with a spoonful of water, then uncover briefly to reset the glaze.

If the pork is sharing a smoker with ribs or a shoulder, give each cut space and finish it independently. The St. Louis ribs guide describes a different bark and tenderness test. The pork butt guide is useful when you want a less rich main dish for a larger crowd.

Common mistakes and fixes

Using cured bacon. Bacon has a different salt level and cooking behavior. Start with uncured belly for this guide.

Cutting tiny cubes. Small pieces dry and scorch before the fat in the center softens. Keep pieces close to 1½ inches and sort thin ends separately.

Pan cooking from the beginning. A covered or solid pan traps moisture and prevents exposed bark. Give the cubes time on an open rack first.

Overloading the sauce. A deep bath produces soft, sweet cubes with little smoke character. Coat lightly, then reduce the liquid uncovered.

Following a rigid hour count. Both pit heat and belly composition vary. Check color, probe feel, and glaze consistency. Cook to internal temperature, not to the clock.

Trying to fix bitter smoke with sweetness. A harsh fire leaves a harsh taste. Keep airflow open, use dry fuel, and maintain a clean burn. Sweet sauce can complement smoke, but it cannot erase creosote.

Serving only rich food. Burnt ends are best in small portions with pickles, slaw, beans, or a sharp salad. That contrast makes the pork taste more vivid.

A practical first batch

For a first attempt, choose a skinless slab with even lean streaks, cube it consistently, and run the smoker at 250°F. Use a moderate rub and a sauce you already like. Smoke until the bark is dry, cover only until the cubes are probe tender, and finish uncovered until the glaze sticks. Note the cube size, pit temperature, and stage transitions so your next batch can be tuned to your smoker.

The best result is tender, smoky pork with defined edges and a sauce that supports it. When in doubt, hold back sauce and give the meat time. You can add glaze at the end; you cannot rebuild bark after the cubes have spent hours submerged.
