Dry-Aged Barnsley Chops with Lemon & Anchovy Butter, New-Season Asparagus & Crushed Peas
Britain’s most generous chop — a double saddle cut burnished in a cast-iron pan and finished with a deeply savoury, citrus-flecked anchovy butter — a complete midweek supper in under 30 minutes.
The Barnsley chop is a proudly British cut — a double saddle chop, cross-cut through the loin so you receive both the tender eye of loin and the sweet fillet in one magnificent piece. It is thick, generous, and completely self-sufficient as a plate: sear it hard in a cast-iron pan, rest it while you finish the peas, and the anchovy butter does all the sauce work as it melts slowly across the surface. In late May, with the first British asparagus at its sweet, fleeting best and good garden peas just arriving, this is one of the most time-efficient, most delicious things you can put on the table on a weeknight.
The Barnsley chop is taken as a transverse cross-section through the whole saddle of the lamb, giving you both loin muscles in one piece: the larger, mild eye of loin on one side of the central vertebra, and the smaller, sweeter fillet on the other. Because it comes from the loin — the least-worked muscle running along the back of the animal — the meat is naturally tender and fine-grained, requiring no marinating, no slow cooking, and no special technique beyond a screaming-hot pan and a watchful eye.
At Thomas Joseph Butchery, our Barnsley chops are cut from grass-fed, dry-aged lamb. The dry-ageing tenderises further and concentrates the lamb’s characteristic sweetness into something more defined and mineral. When buying, look for chops of at least 3cm thickness — anything thinner will overcook before the exterior has developed a proper crust. The fat should be creamy-white and close-grained; the meat a deep, clear pink.
- 2 dry-aged Barnsley chops (approx. 350–400g each, at least 3cm thick)
- 1½ tbsp ghee or light olive oil
- Fine sea salt and freshly cracked black pepper
- 60g unsalted butter, softened to room temperature
- 4 good-quality anchovy fillets in olive oil, finely chopped
- 1 small clove of garlic, finely grated
- Finely grated zest of 1 unwaxed lemon
- 1½ tbsp finely chopped flat-leaf parsley
- Pinch of dried chilli flakes
- 1 bunch new-season British asparagus (approx. 200g), woody ends snapped off
- 200g fresh podded peas (or good-quality frozen petits pois, defrosted)
- 25g unsalted butter
- 2 tbsp full-fat crème fraîche
- Small handful of fresh mint leaves, roughly torn
- Juice of ½ lemon
- Fine sea salt and white pepper
- Make the anchovy butter. Beat the softened butter until smooth. Add the anchovies, garlic, lemon zest, parsley and chilli flakes and mix until evenly combined. Roll into a cylinder in cling film and refrigerate. Can be made several days ahead.
- Bring the chops to temperature. Remove the chops from the fridge at least 30 minutes before cooking. Pat both surfaces thoroughly dry with kitchen paper — surface moisture is the enemy of a good crust. Season generously with fine sea salt on both sides.
- Prep the peas. If using fresh peas, blanch in well-salted boiling water for 2 minutes, drain and run under cold water. If using defrosted petits pois, no blanching needed.
- Cook the asparagus. Bring a pan of well-salted water to a rolling boil. Cook the asparagus for 2–3 minutes until tender with some bite remaining. Drain and set aside.
- Sear the chops — first side. Heat a large cast-iron or carbon-steel pan over a high flame until smoking hot. Add the ghee or light olive oil. Lay the chops flat and sear without moving for 3–4 minutes until a deep, mahogany crust has formed and the meat releases cleanly from the pan.
- Second side & fat-cap render. Flip and sear the second side for 3 minutes. Hold each chop upright with tongs to render the fat cap for 1–2 minutes until amber and lightly crisped.
- Check & rest. Aim for 60–63°C internal at the thickest point for a blushing-pink medium. Rest on a warm plate, tented loosely in foil, for a minimum of 5 minutes.
- Finish the peas. Melt 25g butter, warm peas 1–2 minutes, stir in crème fraîche and lemon juice. Season. Roughly crush a quarter of the peas. Fold in torn mint.
- Warm the asparagus. Return to the pan with a knob of butter over medium heat for 60–90 seconds. Season with salt.
- Plate & serve. Spoon peas onto warm plates. Arrange asparagus alongside. Set rested chops on top, bone-side up. Lay a 1cm disc of anchovy butter on each chop. Scatter parsley, grind over black pepper, and serve immediately.
The backbone of this recipe is the screaming-hot dry sear. Ensuring the meat surface is completely dry before it hits the pan creates the conditions for rapid Maillard browning — the cascade of reactions between amino acids and sugars that generates the deep, complex crust flavour of a properly cooked chop. Any moisture on the surface means the pan must first evaporate that liquid before browning can begin; by then, the interior is already overcooking.
The anchovy butter works on two levels. Anchovies are extraordinarily rich in glutamates — the molecules responsible for umami depth — amplifying the savoury character of the lamb without tasting fishy. The fat in the butter carries aromatics (garlic, lemon, parsley) across the entire surface of the meat as it melts, doing the work of a sauce with none of the technique. The crème fraîche in the crushed peas adds a slight acidity that lifts the whole plate, preventing the richness of the chop and butter from tipping into heaviness.
Thick-cut loin chops or lamb leg steaks work well; reduce searing time by about a minute per side. For pork, a dry-aged free-range pork T-bone chop is treated identically. No anchovies? Add extra lemon zest, a few drops of Worcestershire sauce, or a teaspoon of finely chopped capers. Asparagus past its best? Tenderstem broccoli, fine green beans, or later in summer, podded broad beans with mint make excellent substitutes.
The anchovy butter keeps up to five days in the fridge or three months frozen. Peas can be blanched hours ahead. Cooked chops are best eaten immediately; refrigerate leftovers within two hours and consume within a day — cold Barnsley chop is excellent sliced thinly over a salad.
- A wet pan surface before searing. Pat the chops completely dry and ensure your pan is properly smoking before they go in. Steam is the enemy of a good crust.
- Moving the chops too early. Leave them untouched for the full 3–4 minutes on the first side. They will release naturally when the crust has set. Premature movement tears the crust and causes sticking.
- Skipping the rest. Even 5 minutes of resting redistributes the juices. Cut into a lamb chop immediately and you’ll see them flood the board. Rest it and they stay in the meat where they belong.
Ask your butcher to French-trim the rib bone — it gives a clean, restaurant finish and makes the chops considerably easier to hold at the table. It takes two minutes and makes a visible difference to the presentation.
Wine: A young, unoaked Côtes du Rhône (Grenache-dominant): bright red fruit, garrigue herbs and a peppery edge that matches lamb instinctively.
Beer: A light, hoppy pale ale — the bitterness complements the richness of the anchovy butter without competing with the lamb.
Non-alcoholic: Elderflower cordial, sparkling water, squeeze of lemon — the floral sweetness mirrors the citrus-herb notes of the butter.
The asparagus and crushed peas make this a self-contained plate. If extending the meal: Jersey Royals simmered with butter and salt, or a crisp green salad dressed with lemon and olive oil. A small pot of good Dijon or mint sauce alongside for those who want it.
What is a Barnsley chop?
A Barnsley chop is a double loin chop of lamb cut transversely through the whole saddle. In a single thick slice you get both sides of the loin — the larger eye of loin and the smaller, sweeter fillet in the centre, connected by the vertebra. Like the difference between a T-bone and a regular sirloin steak.
How do I know when Barnsley chops are done?
An instant-read thermometer into the thickest part of the loin, away from the bone: 60–63°C for medium (blushing pink); 65–68°C for medium-well. Beyond 70°C the meat tightens significantly. The chops will carry over 2–3°C during the rest.
Can I cook Barnsley chops in the oven instead?
Yes. Sear in a heavy oven-safe pan, then transfer to 180°C fan for 5–7 minutes for medium. Ideal for four or more, as you can sear in batches and finish all chops simultaneously.
Can I use frozen peas for the crushed peas?
Absolutely. Good-quality frozen petits pois are an excellent substitute — picked and frozen at peak sweetness, often sweeter than fresh peas that have been sitting around. Defrost in cold water and drain well before using.
Do the anchovies in the butter make it taste fishy?
No. The anchovies dissolve entirely on contact with the warm butter, contributing quiet savoury depth rather than identifiable fishiness. Glutamates in the anchovy amplify the lamb’s natural savouriness without announcing themselves. If you’re still hesitant, substitute extra lemon zest and a few drops of Worcestershire sauce.
