Pork Belly Slices Recipe UK: Crispy Bark, Juicy Core in One Pan

This pork belly slices recipe delivers crispy bark and juicy core in one pan—no fancy equipment needed. I've perfected this technique after years of testing, balancing high heat for that coveted crackle with slow cooking to keep the meat tender.

The secret lies in precise timing and temperature control, ensuring every slice has that restaurant-quality texture we all crave.

What sets this recipe apart is the simplicity of the method: just a single pan, minimal prep, and about 45 minutes of active cooking time. You'll start with thick-cut pork belly slices, seasoned with a blend of salt, pepper, and a touch of brown sugar for that caramelized edge.

The key is cooking them skin-side down first, then flipping only once to render all that delicious fat while keeping the inside moist.

By the time you're done, you'll have slices with shatteringly crispy skin that gives way to tender, melt-in-your-mouth pork. The rendered fat creates a glossy sheen and adds rich flavor to every bite.

This is the kind of dish that transforms a simple weeknight dinner into something special—perfect for serving with roasted vegetables or a crisp green salad.

Don't worry if you've never cooked pork belly before—I'll walk you through every step, including how to check for doneness and when to rest the meat for the best results. The technique is foolproof once you understand the science behind it, and the reward is worth every minute of effort.

Ingredients for pork belly slices recipe uk

Thick-cut pork belly and simple pantry staples for restaurant-style slices at home.

The pork belly is non-negotiable—thick-cut slices with the skin on are key for that crispy bark. Tesco Finest or Waitrose usually stock excellent quality, or ask your butcher for a well-marbled cut. Look for slices about 1/2-inch thick—thinner ones won't render enough fat for that juicy core. I always buy a bit extra since the fat trimmings make amazing crackling. For the brown sugar, Demerara works best—it's coarser and caramelizes beautifully. Fresh herbs? M&S or Ocado have great pre-chopped mixes if you're short on time.

No fresh rosemary? Dried works at half the amount, but fresh gives that proper aroma. Swapping the olive oil for vegetable oil is fine—just use a high smoke point variety. For the lemon juice, bottled is okay in a pinch, but fresh makes all the difference. If you're worried about the pork belly being too fatty, pat it dry with paper towels before seasoning—this helps the crust form better. The garlic and thyme can be swapped for 1 tsp garlic powder and 1 tsp dried thyme if needed, though fresh is always superior.

Pork belly keeps best in the fridge for 2-3 days before cooking, but it's fine to prep ahead. The rendered fat? Gold dust—save it in a jar for future roasts or stir-fries. Leftovers reheat beautifully—10 minutes at 350°F (175°C) in the oven with a splash of water to revive the crisp. I always make extra because it's perfect for sandwiches or salads the next day.

Step-by-step instructions for crispy pork belly slices

Here's how to achieve that perfect balance of crackling skin and tender meat in one pan.

Start by patting the 1.5 lb pork belly slices completely dry with paper towels—this is non-negotiable for crispy skin. I like to press down firmly, especially on the thickest parts, to remove any moisture that would prevent browning. Place the slices on a wire rack set over a baking sheet and refrigerate uncovered for at least 1 hour (or up to 4 hours). This cold exposure helps render fat more evenly and creates that prized crackling texture.

While the pork chills, combine 1.5 tbsp kosher salt, 1 tsp freshly ground black pepper, and 1 tbsp light brown sugar in a small bowl. Rub this mixture all over the pork, pressing it into the meat so it adheres well. The sugar will caramelize during cooking, adding depth to that crispy bark. Let the seasoned pork rest at room temperature for 30 minutes before cooking—this ensures even cooking from edge to center.

Heat 0.5 cup vegetable oil in a large, heavy skillet over medium-low heat until it shimmers but doesn't smoke—you want 275°F (about 135°C). Add the pork belly slices fat-side down and cook undisturbed for 8-10 minutes, letting the fat render slowly. This gentle heat prevents burning while allowing the skin to develop a golden crust. You'll see the fat bubbling and turning golden—this is your signal to flip.

Flip the slices and cook for another 8-10 minutes on the second side. The pork should be deep golden brown with crispy skin on both sides. If the fat in the pan starts to smoke excessively, reduce the heat slightly—you want it to render slowly, not burn. Once the skin is crispy and the internal temperature reaches 145°F (measured with an instant-read thermometer), remove the pork to a plate and tent loosely with foil to keep warm.

In the same skillet (don't wipe it clean—those browned bits are flavor gold), reduce the heat to low and add 1 tbsp extra-virgin olive oil. Toss in 3 minced garlic cloves and cook for 30 seconds until fragrant—don't let them brown or they'll turn bitter. Add 0.25 cup chopped fresh rosemary, 0.25 cup chopped fresh thyme leaves, and 0.25 cup chopped fresh parsley, stirring for 1 minute to release their aromas.

Return the pork belly slices to the skillet, spooning the herb oil mixture over the top. Cook for 1-2 minutes to heat through and absorb the flavors. Finish with 1 tbsp freshly squeezed lemon juice, tossing gently to coat. The acidity brightens the rich pork and balances the sweetness from the brown sugar. Let the pork rest for 5 minutes before serving—this ensures the juices redistribute, keeping every slice succulent.

Slice the pork belly into ½-inch thick pieces and arrange on a serving platter. The skin should be deep golden brown and crackly, while the meat inside remains tender and juicy. Garnish with additional fresh parsley if desired and serve with your favorite sides—think roasted vegetables, a simple green salad, or steamed rice to soak up those delicious juices.

Here's the thing—this dish tastes best served immediately while the skin is still crispy. If you need to reheat, do so in a 350°F (175°C) oven for 5-10 minutes to restore the crispiness. The contrast of that shatteringly crisp exterior with the melt-in-your-mouth interior is what makes this recipe truly special. Enjoy every bite!

UK-Inspired Sides

For a proper British spread, serve your pork belly slices with Yorkshire puddings—their airy, crispy texture contrasts beautifully with the rich pork.

I like to make mini versions in a muffin tin, using 1 cup all-purpose flour, 1 cup whole milk, and 1 egg, baked at 425°F (220°C) for 20 minutes.

A classic apple and cabbage braise (sautéed with onions, apples, and a splash of cider) adds sweet-tart balance. 🍏

Fresh Green Pairings

Brighten the richness with a watercress salad—toss 4 cups watercress with 1 tbsp crème fraîche, 1 tsp Dijon mustard, and a drizzle of honey and walnut dressing (whisk 2 tbsp honey, 1 tbsp walnut oil, and 1 tbsp apple cider vinegar).

The peppery greens cut through the fat while the nutty dressing adds depth. For extra crunch, add ¼ cup toasted walnuts.

Starchy Complements

Buttery mashed potatoes with roasted garlic elevate the dish—use 2 lbs Yukon Gold potatoes, boiled until tender, then mashed with ½ cup unsalted butter, ½ cup warm milk, and 2 roasted garlic cloves. For a twist, fold in ¼ cup crumbled Stilton cheese to add a sharp, creamy note. Serve in a warm dish to keep the texture smooth.
