Ingredients for pork belly slices recipe uk
Pork belly's rich fat and tender meat meet savory British pub flavors in this crisp-skinned recipe.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly (Skin-On) 🥓 | 2 lb | Thick-cut, skin scored in diamond pattern |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred, coarse grain |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | From pepper grinder for maximum flavor |
| Smoked Paprika 🌶️ | 1 tsp | Spanish or Hungarian for authentic smokiness |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For brushing after roasting, fruity variety |
| Apple Cider Vinegar 🍎 | 1 tbsp | For basting, organic preferred |
| Fresh Thyme Leaves 🌿 | ¼ cup | Or 1 tbsp dried thyme if fresh unavailable |
| Garlic Cloves 🧄 | 4 cloves | Minced for dry rub, peeled |
| Brown Sugar 🍚 | 1 tbsp | Lightly packed, for caramelization |
| Pickled Red Onions 🧅 | ½ cup | For serving, store-bought or homemade |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish, stems removed |
The pork belly makes all the difference—look for thick-cut pieces with good marbling. Waitrose or M&S often carry excellent cuts, or ask your butcher for 'pork belly for crackling'. Score the skin in a diamond pattern with a sharp knife before seasoning—this creates those signature crispy shards. I always buy the belly a day ahead and let it sit uncovered in the fridge to dry-brine slightly, which helps the crackling form better. For the smoked paprika, Penzeys or Scharffen Berger brands deliver that authentic British pubhouse smokiness, but any quality smoked variety works. The garlic and thyme should be fresh—dried spices just won't give that same depth of flavor that makes this dish restaurant-quality.
No smoked paprika? Substitute half the amount of regular paprika plus a pinch of liquid smoke. Running short on thyme? Fresh rosemary at half the quantity works beautifully. For the vinegar, balsamic vinegar at double the amount adds sweetness if you're serving with sweet accompaniments. The brown sugar is optional but worth it—it helps create that caramelized crust. If you're making this ahead, the pork belly actually tastes better the next day as the flavors meld. Just reheat under the broiler for 2-3 minutes to restore the crispiness. For serving, I always make a quick apple cider reduction by simmering 1 cup apple cider with 1 tbsp brown sugar until reduced by half—it's the perfect drizzle for these slices.
Store any leftovers in an airtight container in the fridge for up to 3 days, but honestly, they rarely last that long. The crackling loses its crispness over time, so it's best enjoyed fresh. For freezing, wrap each slice individually in parchment paper, then store in a ziplock bag for up to 3 months. To reheat from frozen, bake at 375°F (190°C) for 15-20 minutes until the crackling is crisp again. These slices reheat beautifully, making them perfect for meal prep—just portion them into individual servings before freezing. The pickled onions and parsley can be stored separately in the fridge for up to 1 week, ready to brighten up your slices whenever you're ready to serve.

Step-by-step instructions for crispy-skinned pork belly slices
Transforming pork belly into perfectly crisp-skinned slices takes patience and precision—here's how to nail it every time.
Score and Cure the Pork Belly
Begin by scoring the skin of the 2 lb pork belly in a diamond pattern using a sharp knife. This creates channels that render fat during cooking, resulting in that coveted crackling texture. Work carefully—press just deep enough to cut through the skin but not into the meat below.
Next, create a dry rub by combining the 1.5 tbsp kosher salt, 1 tsp freshly ground black pepper, 1 tsp smoked paprika, and 1 tbsp brown sugar in a small bowl. Pat the scored pork belly dry with paper towels (moisture is the enemy of crispy skin), then generously coat all surfaces with the rub. Press it into the skin and meat so it adheres well. Place the pork belly on a wire rack set over a baking sheet to allow air circulation on all sides.
Cold Cure for Maximum Flavor
Refrigerate the rubbed pork belly uncovered for at least 12 hours, ideally overnight. This dry curing process draws out moisture from the meat, which is crucial for achieving that crispy exterior. The salt and spices will penetrate deeply, ensuring every slice is flavorful from edge to edge.
I know it's tempting to skip this step, but trust me—this is where the magic happens. The longer you cure, the better the texture and flavor. If you're short on time, a minimum of 6 hours will still yield good results, though the skin won't be quite as crispy.
Roast Low and Slow for Perfect Texture
Preheat your oven to 275°F (135°C). Place the cured pork belly fat-side up on the wire rack and roast for 2.5 hours. This low temperature allows the fat to render slowly and evenly without cooking the meat too quickly. Every 30 minutes, spoon the rendered fat back over the pork belly to keep it moist and flavorful.
Here's the thing—you're looking for internal temperature of 160°F (71°C) in the thickest part of the meat. Use a meat thermometer to check; the pork belly should be tender but not falling apart. The skin should be golden brown and starting to crisp in spots. If it's not crispy enough at this stage, don't worry—we'll fix that next.
Achieve the Crispy Skin
Remove the pork belly from the oven and increase the temperature to 425°F (220°C). Brush the skin generously with the 1 tbsp extra-virgin olive oil, then return it to the oven for 15-20 minutes. This high-heat finish is what transforms the skin from tender to gloriously crispy.
Watch closely during these final minutes—the skin should develop deep golden-brown spots and begin to crackle. If it browns too quickly, tent it loosely with foil to prevent burning. The pork belly is ready when the skin is crispy and the internal temperature reaches 165°F (74°C).
Rest and Slice for Serving
Transfer the pork belly to a cutting board and let it rest for 15 minutes before slicing. This resting period allows the juices to redistribute, ensuring each slice is moist and flavorful. While it rests, prepare the pickled red onions by draining them and patting dry with paper towels.
Slice the pork belly against the grain into ½-inch thick slices. Garnish each serving with the 0.25 cup chopped fresh parsley and a generous spoonful of the pickled red onions. The contrast of the crispy, savory pork belly with the tangy onions is pure perfection. Serve immediately with your favorite sides to enjoy the best texture and temperature.
Pro Tips For Making Pork Belly Slices Recipe Uk
- CRACK THE SKIN FIRST: Score the pork belly skin in a crosshatch pattern with a sharp knife—don’t go too deep, just break the surface. This lets fat render properly and prevents a chewy mess when searing. I learned this the hard way after serving slices where the skin stayed rubbery.
- SALT IN LAYERS: Don’t just salt once. Generously season the pork belly with kosher salt before searing, then again after resting—about 1 teaspoon per 100g. The first layer preps the meat, the second locks in flavor. My grandmother swore by this, and she was right: dry salt > wet rubs for crispy skin.
- LOW-AND-SLOW REST: After searing, transfer the pork belly to a 120°C (250°F) oven for 2–2.5 hours, covered loosely with foil. This cooks the meat evenly without drying it out. I used to rush this, and the slices turned out greasy or tough—patience here guarantees tender slices.
- SMOKED PAPRIKA TRICK: Mix the smoked paprika with a pinch of black pepper before applying—it sticks better to the skin and won’t clump. A little olive oil on your fingers helps spread it evenly. Sounds weird, but it works: the spices adhere like glue, not dust.
Storing and reheating this recipe
Fridge Storage
Store your crispy pork belly slices in an airtight container lined with paper towels to absorb any excess moisture—this keeps the crackling crisp for up to 3 days. I like using glass containers because they let me see the beautiful golden skin.
Place them in the fridge uncovered for 10 minutes before storing to help the fat set properly. The slices actually taste better the next day as the flavors meld together. 🥓
Freezer Prep
For long-term storage, wrap each slice individually in parchment paper before placing them in a ziplock freezer bag. This prevents freezer burn and keeps the crackling from sticking together.
Label the bag with the date—these slices freeze beautifully for up to 3 months. I always portion them into individual servings before freezing for quick meals.
Reheating Secrets
To restore that crispy texture, reheat frozen slices in a 425°F (220°C) oven for 15-20 minutes until the skin is golden and crackling again. For fridge-stored slices, I prefer the broiler method: place them on a baking sheet and broil for 2-3 minutes on high, watching closely to avoid burning.
A quick brush with olive oil before reheating helps restore crispiness.
Leftovers Hack
Turn leftover pork belly slices into a delicious pork belly hash the next day. Dice the slices and pan-fry with potatoes, onions, and a fried egg for a hearty breakfast.
I also love adding them to stir-fries or salads for extra protein and flavor. The crispy skin adds a satisfying crunch to any dish. 💡
Garnish Storage
Store the pickled red onions and fresh parsley separately in small airtight containers in the fridge for up to 1 week. The onions will keep their tangy flavor, and the parsley stays fresh for garnishing.
I always keep a small jar of pickled onions in my fridge for quick meals—they brighten up any dish in seconds.
Make-Ahead Tips
Plan ahead by prepping the entire pork belly 2 days in advance—this gives you more time to enjoy the meal without last-minute stress. The flavors develop beautifully during this time, and you can reheat just before serving.
I often make a big batch on Sunday to enjoy throughout the week. Just

Frequently asked questions
Can I use pork belly with the skin off for this recipe?
The skin is essential for that signature crispy crackling texture! While you could use skinless pork belly, you'd miss the star of this dish—the shatteringly crisp fat. If you're set on skinless, try a different cut like pork shoulder and focus on achieving tender, flavorful slices instead.
How do I know when the pork belly is fully cooked?
Use a meat thermometer to check the internal temperature—it should reach 165°F (74°C) in the thickest part of the meat. The skin should be deep golden brown and crispy in spots. If it's not crispy enough after the high-heat finish, broil for an extra 2-3 minutes to restore the texture.
What's the best way to reheat these slices if I made them ahead?
For fridge-stored slices, broil for 2-3 minutes on high until the skin is crispy again. For frozen slices, bake at 425°F (220°C) for 15-20 minutes. A quick brush with olive oil before reheating helps restore that perfect crackling texture.
Can I substitute the smoked paprika with something else?
Yes! If you don't have smoked paprika, mix ½ tsp regular paprika with ¼ tsp liquid smoke for a similar smoky flavor. For a sweeter touch, add ½ tsp brown sugar to the rub. The key is balancing the spices to enhance the pork's natural richness.
What are the best UK supermarket options for pork belly?
For the best quality in the UK, try Waitrose, M&S, or Tesco Finest—they often carry excellent cuts. Ask your butcher for "pork belly for crackling" if you want the thickest, most marbled pieces. Avoid pre-sliced bacon-style cuts, as they won't render fat as beautifully.
