Pork Belly Roast — Low-and-Slow Oven with Crackling Finish

Pork belly dry-brined 24 hours, roasted at 150 °C for three hours until the meat is pull-apart tender, then finished at 240 °C for twenty minutes until the skin blisters into the most satisfying crackling in any kitchen. The oven's answer to kamado secreto — different register, equal drama.

The Crackling Question

Pork belly is two dishes in one: the meat underneath, which wants slow, gentle heat for the fat to render and the collagen to dissolve into gelatin, and the skin on top, which wants a blast of high heat at the end to blister into proper chicharrón-style crackling. The classical Spanish approach cooks them together on the kamado with careful temperature management. The Umami oven approach separates the phases cleanly: three hours at 150 °C renders and tenderizes without touching the skin, then twenty minutes at 240 °C blisters the skin without overcooking the meat. This is the chuletón technique (UMAMI-7 #4) applied to pork belly: decouple the two problems, optimize each separately, bring them together at service.

The non-negotiable prep is the dry brine. 24 hours uncovered in the fridge with 1 percent salt by weight does three things: seasons the meat throughout, dries the skin so it can crackle properly (wet skin steams instead of blistering), and begins gentle enzymatic tenderization. Skip this step and the pork is under-seasoned and the crackling is uneven. It is the difference between a great pork belly and an ordinary one.

Serving is family-style: the whole roast comes to the table on a wooden board, the skin cracking audibly under the knife, the meat pulling apart with a fork. Pair with a simple salad of escarole and apple, crusty bread for the rendered fat, and a bottle of aged Rioja or a Tempranillo-based Spanish red. It is the Sunday meal Spanish families serve when they want to flex without needing to go to a restaurant.

Ingredients

for 6 (generous portions)

0 of 16 pulled

Everyday

The Pork

1 × 1.5–2 kg pork belly, skin-on, bone-out — from a good butcher; ask for one from the rib end (more meat, less pure fat) OR from the flank end (more fat, more dramatic crackling)

The Dry Brine (T-24 h)

15–20 g kosher salt (1% of meat weight)
1 tsp black pepper, freshly cracked

The Rub (Phase 1)

2 tbsp EVOO
1 tsp pimentón de la Vera dulce
1 tsp fennel seeds, toasted and lightly crushed
2 cloves garlic, microplaned
Pinch of cumin (optional)

Substitution Notes

No skin-on pork belly? Skin-off works but loses the crackling finish — still a great braise but a different dish.
Fennel seed unavailable? Coriander seed is a functional substitute; flavor shifts slightly.

No Limits

The Pork — Ibérico

1 × 1.5–2 kg Ibérico pork belly from Meat N' Bone (Miami, Pablo ✓) or Despaña Brand Foods — acorn-fed Spanish black pig, markedly different profile from standard US pork

The Brine + Rub — Spanish DO

Maldon salt at 1% weight
Pimentón de la Vera dulce DO (Pablo priority per MEMORY.md)
Whole fennel seeds from a good spice shop
Las Pedroñeras purple garlic
Arbequina EVOO

Mise en Place

0 of 4 prepped

T-24 h: Pat pork belly dry. Score skin in diamond pattern (2 cm squares, 5 mm deep — through fat only, not into meat). Salt rub across all surfaces. Place on wire rack over sheet pan, uncovered in fridge 24 h.
T-30 min: Remove pork from fridge. Let temper at room temperature. Pat skin dry one more time.
T-20 min: Preheat oven to 150 °C convection. Mix rub: EVOO + pimentón + fennel + garlic.
T-5 min: Brush rub onto meat side ONLY — avoid skin. Place pork on roasting rack, skin-side UP.

Score + Dry Brine (24 h Before)

Pat the pork belly dry thoroughly with paper towels. Both sides, especially the skin.

Score the skin: using a sharp boning knife or a dedicated scoring blade, cut a diamond pattern across the skin. Diamonds should be roughly 2 cm on a side. Cut 5 mm deep — through the skin and fat layer but NOT into the meat. If you cut into the meat, juices will release during roasting and prevent proper crackling.

Rub 15 to 20 g kosher salt (1% of the meat's weight) across all surfaces — skin, meat, sides. Use your fingers to work salt into the diamond scores.

Crack black pepper over the meat side (NOT the skin).

Place on a wire rack set over a rimmed sheet pan. Do not cover.

Refrigerate 24 hours. The skin will dry significantly — this is essential for proper crackling.

Phase 1 — Low and Slow (150 °C × 3 h)

Preheat oven to 150 °C convection. Position rack in middle of oven.

Remove pork from fridge. Let temper 30 min at room temp.

Pat skin one more time with paper towels.

Brush the meat side only with the pimentón-fennel rub (2 tbsp EVOO + 1 tsp pimentón + 1 tsp crushed fennel + microplaned garlic). Do not brush the skin — oil on skin interferes with crackling.

Place pork on roasting rack, skin-side UP, in a large roasting pan.

Insert probe thermometer into thickest meat section, avoiding the skin and fat layers.

Roast 3 hours at 150 °C convection. Do not open the oven during this phase.

Target at end of Phase 1: meat internal temperature 88 to 90 °C, pork tender and pullable, skin dry and leathery (NOT yet crackled — that's Phase 2).

Phase 2 — High Blast Crackling (240 °C × 15–20 min)

Remove pork from oven. Crank oven to 240 °C (or maximum setting, convection off or on — either works at this temperature).

While oven ramps up (10 min), let pork rest on counter. Do not tent or cover — skin needs to stay dry.

Once oven is at 240 °C: return pork, skin-side UP. Position as close to the top heating element as the oven allows.

Roast 15 to 20 minutes . Watch closely from 12 min onward.

Crackling cues: skin will blister, puff up in diamond sections, turn deep golden-brown, and become audibly crisp when tapped with tongs.

Pull when: skin is uniformly blistered and deep golden. Burn risk is real — 3 minutes of inattention can turn crackling into charcoal.

If parts of the skin refuse to crackle: a blowtorch across those sections for 30 seconds delivers the final blister.

Rest + Carve + Serve

Transfer to a grooved cutting board.

Tent LOOSELY with foil — not pressed down on the crackling.

Rest 20 minutes . Interior equalizes; crackling stays crispy.

Carving: use a heavy chef's knife. Press straight down through the crackling with the knife's tip first, then through the meat — a smooth pressing motion rather than a sawing motion.

Slice 2 cm thick portions through skin and meat together. Each portion should have a section of intact crackling on top of pull-apart meat.

Serve family-style on the cutting board OR pre-plate each portion. Crusty bread alongside for the rendered pan fat (do not discard — it's flavored pork fat, excellent for future roasted potatoes).

Timeline

T-24 h — Score + salt + dry brine Diamond-score the skin. Salt all surfaces. Uncovered rack in fridge, 24 h.
T-30 min — Temper + preheat Pork to room temp. Oven to 150 °C convection.
T=0 — Phase 1 begin Pork onto rack, skin-side UP. Probe in thickest meat section (avoid skin). Into oven 150 °C.
T+2 h — Check rendering Fat should be rendering visibly. Meat internal ~70 °C. Skin dry and leathery (that's correct — will crackle Phase 2).
T+3 h — End Phase 1 Meat internal 88–90 °C. Pork is tender. Skin is firm, dry, NOT crackled yet. Remove from oven.
T+3:00 — Oven ramp Crank oven to 240 °C (or max). 10 min preheat.
T+3:10 — Phase 2 begin Pork back in at 240 °C. Position near top heating element if possible.
T+3:25–3:30 — Crackling check Skin should be blistered, golden-brown, bubbled into proper crackling. If pale or flat: 3 more minutes.
T+3:30 — Rest Out of oven. Loose foil tent. Rest 20 min. Crackling stays crispy; interior equalizes.
T+3:50 — Carve + serve Score through crackling with heavy knife. Slice 2 cm thick portions through skin and meat together.
