A pork loin joint is one of the great Sunday roasts. It's leaner than shoulder, quicker to cook than belly, and when you get it right, it delivers tender, flavourful meat and the kind of crackling that makes the whole table go quiet.
The problem is that pork loin is also one of the easiest joints to get wrong. Because it's a leaner cut, it has less fat running through the meat to keep it moist during cooking.
Overcook it by even ten minutes and you'll end up with dry, tight slices that no amount of gravy can fully rescue.
The good news is that with a few straightforward techniques, a pork loin joint is actually very forgiving and genuinely impressive on the table. Here's everything you need to know.
________________________________________
What Is Pork Loin and Why Choose It?
The loin runs along the back of the pig, between the shoulder and the leg. It's a relatively lean muscle that doesn't do a great deal of work, which means it's naturally tender without needing long, slow cooking.
Compared to shoulder, which needs three to five hours in the oven to break down its connective tissue, loin can be on the table in an hour and a half to two hours depending on the size of the joint. That makes it a more practical option for a midweek roast or when you're not planning your Sunday around the oven.
The trade-off is that with less fat comes less margin for error. A shoulder will forgive you if you leave it in twenty minutes too long. A loin won't. But cook it correctly and you'll have beautifully juicy, tender meat with exceptional flavour, particularly when the pork is properly reared to begin with.
Our pork loin is produced from pigs born and reared outdoors at Blakenhall Park Farm in Staffordshire, progressing through large outdoor paddocks before moving to spacious, naturally lit barns. They're allowed to develop at their own pace, which produces pork with a depth of flavour that supermarket loin simply can't match. Our pork loin has been recognised at the Great Taste Awards, including a three-star award in 2023 and a Gold Award at the Great British Food Awards 2024, which judges called outstanding.

Choosing the Right Size
We offer our pork loin joint in two sizes:
Medium, approximately 1.5kg, suitable for up to four people. This is the right choice for a family Sunday lunch with all the trimmings, or a smaller gathering where you want generous portions.
Large, approximately 3kg, suitable for up to eight people. Ideal for a bigger table, a special occasion, or if you want cold pork leftovers through the week, which are frankly one of the great pleasures of a Sunday roast.
As a general guide, allow around 200 to 250g of boneless joint per person before cooking.

Preparing the Joint
- Remove it from the fridge in time. This is one of the most commonly skipped steps in roast cooking and one of the most important. Take the joint out of its packaging at least 30 minutes before it goes in the oven, ideally 45 minutes to an hour for a larger joint.
- Taking the chill off the joint. This can help it cook more evenly from the outside in, reducing the risk of a dry exterior and an undercooked centre.
-
Score and salt the skin for crackling. If your joint has the skin on, this is where your crackling begins. Using a sharp knife, score the skin at roughly 1cm intervals, cutting through the fat but not into the meat below. Then rub a generous amount of fine sea salt into the scored skin, getting it down into the cuts. Some people add a little oil too; others go salt only. Both work. What matters is the salt and the scoring.
-
Dry the skin thoroughly. Moisture is the enemy of crackling. Pat the skin dry with kitchen paper before salting. If you have time the evening before, unwrap the joint and leave it uncovered in the fridge overnight. The cold air will dry out the skin further, giving you a better start.
- Bring your oven to temperature first. Preheat the oven properly before the joint goes in. Don't rush this step.

Cooking the Joint
Temperature: 200°C, fan 180°C, Gas Mark 6.
Timing: 30 minutes per 500g, plus an additional 30 minutes.
So for a 1.5kg joint, that's 90 minutes plus 30 minutes, giving you around two hours total. For a 3kg joint, you're looking at approximately three and a half hours.
The method:
- Place the joint skin side up in a roasting tin. There's no need to add water or stock to the tin for loin; unlike shoulder it doesn't need the steam, and the moisture will work against your crackling.
- Put the joint in the oven at the temperature above and leave it. Resist the urge to open the door repeatedly; every time you open the oven you lose heat and extend the cooking time.
- For the final 20 to 30 minutes, if the crackling isn't yet blistered and crisp, turn the oven up to 220°C, fan 200°C, or switch to the grill function with the joint on a high shelf. Keep a close eye on it at this point as it can go from golden to burnt quickly.
- Check it's cooked. Insert a skewer or meat thermometer into the thickest part of the joint, avoiding any bone. The juices should run clear, not pink. If you have a meat thermometer, you're looking for an internal temperature of 70°C held for two minutes, or 75°C if you prefer to be conservative. Don't aim higher than this or you'll be heading into dry territory.

The Rest Is Everything
This step is non-negotiable and frequently ignored. When meat comes out of a hot oven, the juices are being pushed towards the centre of the joint under pressure from the heat. If you carve immediately, those juices will run straight out onto the board and the meat will be noticeably drier.
Resting allows the fibres to relax and the juices to redistribute through the meat. For a pork loin, rest it for a minimum of 20 minutes, covered loosely with foil. For a larger joint, 30 minutes is better.
The crackling will stay crisp during this time. If it softens slightly, a quick blast under the grill for two or three minutes before serving will bring it back.
________________________________________
Carving
Carve against the grain, which on a loin joint means slicing across the width of the meat rather than along its length. This cuts across the muscle fibres and produces more tender slices.
Use a long, sharp carving knife. A blunt knife drags through the meat and tears it. If you don't have a carving knife, a long bread knife can work in its place.
For the crackling, a separate, heavy knife or kitchen scissors will do a better job than trying to carve through it with the same blade.

What to Serve With It
Pork loin is a versatile roast that suits a range of accompaniments. Here are our favourites:
Apple sauce. The natural pairing with pork and for good reason. The sharpness of the apple cuts through the richness of the meat. Make your own if you can; peel, core and roughly chop three or four Bramley apples, cook gently with a splash of water and a little sugar until soft, then mash or blitz to your preferred texture.
Roast potatoes. Non-negotiable. Use the fat from the roasting tin to roast your potatoes; pork fat produces excellent results.
Roasted root vegetables. Parsnips, carrots and fennel all work particularly well with pork.
Mustard. English or wholegrain, on the side. Pork and mustard is a combination that needs no improvement.
Gravy. Use the resting juices from the joint as your base. Add a little stock, a splash of white wine or cider if you have it, and thicken with a small amount of cornflour mixed with cold water. Season and you're done.

A Note on Quality and Flavour
A pork loin from a properly reared, slow-grown pig will behave differently in the oven to a supermarket joint. The fat is distributed more evenly, the muscle fibres are well developed and full of flavour, and the joint often produces richer roasting juices with less excess liquid during cooking.
You'll notice it in the roasting tin: a well-reared joint produces golden, flavourful juices that make an excellent base for gravy. Better-quality pork often browns more effectively and produces rich roasting juices, although some moisture release is natural and can also be influenced by processing, storage and cooking temperature.
This is why starting with good pork matters. The cooking technique is the same; what you're cooking makes a significant difference to what ends up on the plate.

Common Mistakes and How to Avoid Them
Cooking straight from the fridge. The outside overcooks before the centre reaches temperature. Always rest the meat at room temperature first.
Wet skin. Moisture prevents crackling. Dry the skin thoroughly and salt it generously.
Opening the oven repeatedly. Every degree of lost heat extends your cooking time unevenly. Trust the timing and leave it alone.
Skipping the rest. Carving too early produces dry meat. Cover it and wait; it's worth it.
Overcooking. Loin has little fat to protect it from drying out. Use a meat thermometer if you have one and don't cook beyond 75°C internal temperature.

Leftovers
Cool leftovers promptly and store them in the fridge.
Cold pork loin slices beautifully and is excellent the next day in sandwiches, particularly with good bread, apple sauce and a little rocket. It also works well in stir fries, fried rice, or sliced thinly over a green salad with a mustard dressing.
The bones, if your joint is bone-in, make a good stock base. Cover with cold water, add a halved onion, a few peppercorns and a bay leaf, bring to a gentle simmer and cook for two to three hours. Strain and use as the base for a pea and ham soup or a simple broth.
Leftover pork loin can be used in:
- pork and apple sandwiches;
- pork, stuffing and gravy rolls;
- fried rice;
- noodle dishes;
- salads;
- pork and vegetable pie;
- wraps;
- bubble and squeak;
- pasta dishes.
Because pork loin is lean, reheat it gently with a little gravy, stock or sauce to prevent it from drying out.
Only reheat the amount you intend to eat and ensure it is thoroughly hot before serving.

Frequently Asked Questions
How do I stop roast pork loin drying out?
Avoid overcooking, check the temperature before the estimated finish time and rest the joint for at least 15–20 minutes before carving.
How do you get crispy crackling?
Dry the rind thoroughly, score it evenly, rub salt into the cuts and begin cooking in a hot oven. Keep stock, water and steam away from the skin.
Should I put oil on pork crackling?
A very small amount can be used, but the most important factors are dry skin, salt and an initial burst of high heat. Too much oil can sometimes prevent the surface from drying properly.
Do you cover pork loin when roasting?
No, leave it uncovered while roasting so the skin can crisp. After cooking, loosely cover the meat while it rests, keeping the crackling exposed.
Can I prepare pork loin the night before?
Yes. Pat the joint dry, place it uncovered in the fridge overnight and season it shortly before cooking. This can help dry the rind for better crackling.
Can roast pork loin be frozen?
Raw pork loin can usually be frozen if it has not previously been frozen. Cooked leftovers can also be frozen once cooled. Follow the storage instructions supplied with the product and use suitable airtight packaging.
