Pork Belly Slices Recipe UK: Crispy Layers with British Flair

I first tried pork belly slices at a London gastropub, where the crispy layers and tender meat changed my view of this humble cut. The British approach focuses on slow roasting followed by a high-heat finish for perfect texture.

This method transforms fatty pork belly into golden, crispy slices with melt-in-your-mouth centers. The secret lies in scoring the skin deeply and patting it completely dry before cooking to ensure maximum crispness.

What emerges is a dish with shatteringly crispy tops and unctuous meat beneath, ready to serve with apple sauce or mustard. The contrast between the crackling skin and soft belly makes every bite unforgettable.

Perfect for Sunday roasts or dinner parties. Here’s how to achieve that signature British crispy result at home.

Pork belly is the star here—look for skin-on cuts with even fat marbling at your butcher or the meat counter at Waitrose or M&S. The skin should be thick but not tough. Ask them to score it for you if you’re unsure (saves time and ensures even cooking). I’ve had great results with free-range, outdoor-bred from local farms. Avoid pre-packaged stuff that’s been sitting too long—freshness matters for that perfect crisp.

No fennel seeds? Coriander seeds give a similar earthy note. Fresh rosemary can replace dried at one-third the amount. If apple cider vinegar isn’t handy, white wine vinegar works in a pinch. For the mustard, Dijon is a solid swap if you prefer a sharper kick. The apple sauce can be skipped, but honestly, it’s the ideal partner for cutting through all that richness.

Cooked pork belly keeps in the fridge for up to 4 days—reheat in the oven to revive the crispiness. Freezes beautifully for 3 months if wrapped tightly. Pro tip: save the rendered fat for roasting potatoes (worth the extra effort).

Step-by-Step Instructions for Pork Belly Slices

Here’s how I get that perfect crackling every time—simple, foolproof, and utterly delicious.

Step 1: Cure and Season the Pork Belly

Pat the 2 lb Pork Belly dry with paper towels, focusing on the scored skin. This is non-negotiable for crispiness. Rub the sea salt aggressively into the skin and meat—this draws out moisture and ensures a dry surface that crackles beautifully.

Crack the 2 tsp Black Peppercorns and mix with the 1 tsp Fennel Seeds, 1 tsp Dried Thyme, and 1 tsp Dried Rosemary. Press this mixture evenly over the meat, avoiding the skin. The spices should cling without falling off.

Step 2: Slow-Roast for Tender Meat

Place the pork belly skin-side up on a wire rack set over a baking tray. Add the 6 cloves Garlic Cloves and 2 whole Bay Leaves to the tray beneath the rack. Roast in a preheated 300°F oven for 2 hours. This low and slow start renders the fat and tenderizes the meat.

After 2 hours, increase the oven temperature to 425°F. Brush the skin with the 1 tbsp Olive Oil and return to the oven for 20-25 minutes until the skin puffs up and turns a deep, golden brown. Watch it closely—this is when the magic happens.

Step 3: Rest and Crisp the Skin

Remove the pork belly from the oven and let it rest for 10 minutes. This allows the juices to settle and the skin to firm up slightly. Don’t skip this step, or the juices will spill out when you slice it.

For extra crispiness, return the pork belly to the 425°F oven for another 5-10 minutes. You’re aiming for a skin that shatters when you press it with a knife. The meat beneath should be fork-tender and richly flavored from the slow roast.

Step 4: Slice and Serve with Traditional Accompaniments

Slice the pork belly into thick pieces, ensuring each slice has a portion of the crispy skin and tender meat. Arrange on a serving platter and drizzle with the 2 tbsp Apple Cider Vinegar for a bright, tangy contrast to the richness.

Serve immediately with the 0.25 cup English Mustard and 0.5 cup Apple Sauce on the side. The mustard’s sharpness cuts through the fat, while the apple sauce adds a sweet, fruity balance. Remove the bay leaves before serving—they’ve done their job infusing flavor into the meat.

Storing and Reheating This Recipe

Fridge Storage

Let your pork belly cool completely, then transfer to an airtight container with a paper towel to absorb excess fat. It keeps in the fridge for up to 4 days. The flavors deepen overnight, making leftovers taste even better. ❄️

Freezer Method

Wrap slices tightly in plastic wrap and place in a freezer bag, squeezing out all air. It freezes well for 3 months without losing texture. For best results, freeze in portion sizes you’ll actually use.

Oven Reheating

Preheat oven to 350°F and place pork belly on a wire rack over a baking sheet. Reheat for 10-15 minutes until the skin crisps up again. This method restores that perfect crackling we all love. 🔥

Quick Microwave Fix

For a fast option, microwave slices on medium power for 1-2 minutes, then finish in a hot skillet for 30 seconds per side to revive the crispiness. Cover with a paper towel to prevent splattering.

Make-Ahead Tip

Cook the pork belly a day ahead and refrigerate uncovered overnight. This dries the skin further for even better crackling when reheated. I learned this trick from a pub chef in Cornwall.
