pork Belly
Pork Belly
The boneless underside of the pig, between the shoulder and the ham — alternating seams of fat and lean, sold skin-on or skinless in 1–3 lb pieces off a 10–12 lb whole side. The belly does almost no work, so it never toughens, and it carries enough fat to survive hours of low heat that would ruin a lean cut.

Bacon, before anyone did anything to it.
Buy it if
You have three unhurried hours and you're cooking for people who don't flinch at fat.
What curing actually does. Bacon is this slab plus salt, nitrite, and usually smoke. The salt pulls out water and firms the texture, the nitrite fixes the pink color and blocks Clostridium botulinum, and the smoke supplies most of what people identify as "bacon." Fresh belly has none of it and tastes like very rich roast pork. There is no way to cook bacon flavor into it — you either cure it or buy it cured.
Half of what you pay for is fat, and much of it ends up in the pan. Belly runs near 50% fat by weight, and slow cooking drives a good share of that out of the meat. A 2 lb slab is a main course for four, not six. Judge quantity by what comes out, not by what goes in.
Skin is a decision, not a detail. Skin-on can give you crackling, but only with a dry surface and a hard finish; there is no half-measure, and skin that spends its life in liquid comes out closer to rubber. For braising, dicing, or slicing thin, buy it skinless and skip the argument.
Breed shows up here more than anywhere else on the pig. Because the cut is mostly fat, the difference between a heritage animal — Berkshire, Duroc, Mangalitsa — and commodity pork is plain in a way it simply isn't in a lean chop, where most people could not pick one from the other.

What else it’s called
How to cook Pork Belly
| Best methods | Roast Braise Smoke Sous vide Grill Pan sear |
|---|---|
| Cook to | 145°F is safe; 195–203°F is done. Below that the fat hasn't rendered and the meat still eats tough. |
Two stages, in this order, always: long and low until the fat renders and a probe meets no resistance, then a short blast of high heat for the skin. Reverse them and you get a scorched exterior over fat that never gave up.
For crackling, the skin has to be dry before it ever sees heat — leave it uncovered in the fridge overnight, then score through the fat in lines about half an inch apart, stopping short of the meat so it renders without curling.
Sliced thin for a grill or a hot pan, none of that applies. It only needs to be cooked through and browned at the edges.
Common questions
What is samgyeopsal?
The Korean preparation, and the name means "three-layer flesh" — a description of the cut itself. Skinless belly is sliced thick and grilled at the table with no marinade, then wrapped in lettuce with ssamjang. Same slab as a six-hour roast, cooked in four minutes.
Can I cure my own bacon from it?
Yes, and it's mostly waiting. A dry cure of salt, sugar, and curing salt (sodium nitrite, sold as Prague powder #1) needs about a week in the fridge, turning daily, then a rinse and a smoke. Use actual curing salt rather than table salt — plain salt won't protect against botulism at smoking temperatures.
Is side pork the same thing?
Yes — side pork is uncured belly, usually sliced. It looks exactly like raw bacon in the package, which is why it catches people out in the Midwest, where it's sold alongside it. Cook it and you get pork, not bacon.
Does sous vide work on belly?
Well, and it removes the guesswork. Twelve to twenty-four hours around 170°F renders the fat and breaks down connective tissue without any risk of drying, then it needs chilling, pressing, and a hard sear or a hot oven to finish. The finishing step isn't optional; straight out of the bag the skin is inedible.
