Crispy slow roasted pork belly is a rich, tender centerpiece with deeply golden crackling. This recipe uses pork belly with skin on, a little olive oil, fennel powder, salt, and black pepper, then combines gentle roasting with a brief high-heat finish. The result is juicy meat beneath a crisp crust that is ideal for a relaxed dinner or special occasion.
These little bites work well for a snack table, a casual dinner, or a party where guests can pick them up easily. The filling is mild and creamy, while the wrapper supplies the crisp contrast. Because the pork belly cook in a single layer, they are also easy to make in batches and serve warm.
Crispy Slow Roasted Pork Belly
Start by letting the olive oil soften so it blends smoothly with the seasonings. Stir it with fennel powder, black pepper, and salt until the mixture is evenly seasoned. Keep the wrappers covered while you work so they do not dry out, and set a small bowl of water beside the work surface for sealing.

Prepare the filling and wrappers
Place several wrappers on parchment and moisten their outside edges. A small amount of filling is enough; about one teaspoon lets the wrapper close securely without squeezing the olive oil out during cooking. Fold each wrapper diagonally over the filling, press away trapped air, and pinch the edges closed.
Fold each wonton securely
Bring the two opposite corners toward the center and use a touch of water to hold them in place. The finished shape should be compact and sealed, with no visible gaps. Repeat until all of the filling and wrappers are ready. If a wrapper feels stiff, give it a moment under the cover before folding.

Cook until crisp and golden
Arrange the pork belly in the oven with the folded points facedown, leaving space around each one for air to circulate. Spray both sides lightly with olive oil. Cook at 285°F for four minutes, then spray again, turn the pork belly, and cook for another four to six minutes. They are ready when the wrappers are crisp and golden.
Serve the pork belly warm
Let the pork belly cool briefly before serving because the olive oil center will be hot. Their best texture is fresh from the oven, when the wrapper is crisp and the filling is creamy. Arrange them on a platter and serve them as an appetizer or alongside other small bites.

Helpful cooking tips
Do not overfill the wrappers, and press out air before sealing so the seams stay closed. Work in batches if the basket is crowded; overlapping pork belly will steam instead of crisping evenly. A light oil spray is sufficient, and the final cooking minutes should be watched closely because thin wrappers can brown quickly.
Storage and reheating
These pork belly are best served immediately, but leftovers can be refrigerated in a covered container. Reheat them in the oven until warmed and crisp again. Avoid microwaving when possible, since it softens the wrapper. Cooked pork belly may also be reheated in a single layer so their edges regain some crunch.
Easy variations
For a slightly different flavor, keep the primary filling the same and offer optional dipping sauces at the table. A mild sweet chili sauce or a simple soy-based dip can complement the savory olive oil. Make any sauce separately so the pork belly remain crisp until serving.
Why this appetizer works

The filling comes together in one bowl, folding requires only water for sealing, and the oven provides even heat with very little oil. That makes this recipe approachable for a first batch and convenient enough to repeat whenever a quick appetizer is needed.
What is crispy slow roasted pork belly?
Crispy slow roasted pork belly is a rich cut cooked gently until the meat is tender, then finished at high heat so the skin becomes crackling. The method is simple: keep the flesh protected while it roasts, keep the skin dry, and finish the pork on a level rack.
Why this method works
Slow heat renders the fat gradually and protects the meat from drying out. The short, hotter finish transforms the dry skin into crisp crackling. A few minutes of resting lets the juices settle before slicing.
How to make it
Pat the pork skin dry and leave it uncovered in the refrigerator overnight when possible. Heat the oven to 285°F (140°C), or 250°F (120°C) fan. Rub the flesh with 1 teaspoon oil, fennel, half the salt, and the pepper. Wrap the pork snugly in foil with the skin exposed in an open box. Pat the skin dry, rub it with the remaining oil, and season it with the remaining salt. Roast for 2 1/2 hours, tightening the foil after 1 1/2 hours if the pork has shrunk. Increase the oven to 465°F (240°C). Set the pork on a rack, level the skin with foil balls, and roast for 30 minutes until the crackling is deep golden and crisp. Rest for 10 minutes, then slice and serve.
Optional variation
For an optional variation, add a pinch of fennel powder to the flesh seasoning or serve the sliced pork with apple sauce. Keep the primary cooking temperatures and timing unchanged so the crackling develops properly.
Serving and storage tips
Serve thick slices with a sharp knife and a simple vegetable side. Refrigerate leftovers in a covered container and reheat them in a hot oven so the crackling can regain some texture.
FAQ: frequently asked questions
Should I score the skin?
No. Keeping the skin unscored helps it dry and puff into an even crackling.
Can I skip overnight drying?
Yes, pat the skin as dry as possible, although overnight drying gives the crispest result.
How long should pork belly rest?
Rest it for 10 minutes before slicing so the juices settle while the crust stays crisp.
