Pork Crackling (Crispy Pork Skin)
By Felix Kowalski · Eastern European Cuts Specialist · Updated 2026-05-08
1 lb pork skin scored, salted, slow-roasted at 300°F for 2 hours then crisped at 450°F. Salt only. The savory zero-carb chip alternative.
Carnivore pork crackling is 1 pound of pork skin (with a thin layer of attached fat) scored in a diamond pattern, salted with 1 tablespoon of coarse salt, slow-roasted at 300°F for 2 hours to render the fat, then blasted at 450°F for 15 to 20 minutes to crisp the skin into shattering crackling. Salt is the only seasoning. The two-temperature method is essential — skipping the slow phase leaves the fat unrendered (chewy crackling); skipping the high finish leaves the skin tough (leathery instead of glassy). A 2-ounce serving delivers 12g protein, 18g fat, and 220 calories. Pork skin costs $2 to $5 per pound at butchers and Asian markets; most Western grocery stores don't stock it but will special-order. Yields about 8 ounces of finished crackling per pound of raw skin (heavy weight loss as fat renders out). Eat as a chip-style snack, or crumble over cooked beef as a salty crunch topping.

Instructions
- 1
Pat the pork skin completely dry. Trim any large fat pieces still attached, leaving a ⅛-inch layer of fat on the underside.
- 2
Score the skin in a diamond pattern with a sharp knife or razor — cuts should go through the skin into the fat layer but not all the way through.
- 3
Apply 1 tbsp coarse salt evenly across all surfaces, working into the score marks.
- 4
Place skin-side up on a wire rack inside a sheet pan. Refrigerate uncovered for 12 to 24 hours to dry the skin (essential for the final crisp).
- 5
Preheat oven to 300°F. Roast the skin for 2 hours — the fat renders out and pools in the sheet pan.
- 6
Crank oven to 450°F. Continue roasting for 15 to 20 minutes until the skin puffs up, blisters, and turns golden-brown.
- 7
Pull when the skin shatters when poked with a knife tip. Some pieces puff dramatically; others stay flatter — both crisp.
- 8
Transfer to a plate lined with paper towels. Cool 5 minutes — the crackle texture sets as it cools.

Frequently Asked Questions
Why does my crackling come out chewy?
Two common causes. First, the skin wasn't dried enough before roasting — the 12-to-24-hour refrigerator dry is non-negotiable for crisp results. Wet skin steams instead of crisping. Second, the high-temperature finish was too short or too low — needs at least 15 minutes at 450°F for the skin to puff and shatter. Ovens that don't go above 425°F produce inferior crackling no matter the technique. A pizza stone in the oven boosts performance by improving heat retention.
Pork crackling vs pork rinds?
Different starting points. Pork crackling (this recipe) uses fresh pork skin with attached fat, slow-rendered then crisped. Pork rinds (the bagged snack) start with already-rendered skin pre-dried into pellets, then puffed in hot fat at 425°F+ for the bagged crispy texture. Crackling is denser, fattier, and saltier; pork rinds are airier and crunchier. Both qualify as carnivore-aligned. See the related pork-rinds-homemade recipe for the bagged-style version.
Can I save the rendered fat?
Yes — that's lard. Strain the fat that pools in the sheet pan through cheesecloth into a glass mason jar. Refrigerate for 6 months or use immediately as a cooking fat. Lard from pork-skin rendering is harder and whiter than lard from leaf-fat rendering; both are equally good for cooking. Two birds one stone — rendering crackling produces both the crispy snack and the cooking fat. See lard-rendered-from-pork for the dedicated lard recipe.
