If you want a restaurant-quality dinner in under 20 minutes, this lamb loin chops recipe is the one I keep coming back to. Lamb loin chops are the little “T-bones” of the lamb — tender, quick to cook, and far more forgiving than people expect. The best way to cook lamb loin chops is a hard sear in a hot pan, a knob of butter to baste, and a short rest. That’s it. No marinade required, though I’ll give you a 10-minute one that lifts them even higher.
I’ve cooked these for years for quick midweek suppers and for guests, and the method below gives you a deep brown crust with a blushing pink centre every single time. Below you’ll find the full ingredients list, a numbered method, timings, my own kitchen tips, and a short FAQ for the questions people always ask me.
Why lamb loin chops are the best cut for a quick dinner
Lamb loin chops are cut from the saddle (the loin), so each chop has a small fillet on one side of the bone and a piece of loin on the other — like a miniature beef T-bone. They’re naturally tender, which means they suit fast, high-heat cooking rather than the long, slow braising you’d give tougher cuts like shoulder or shanks. A loin chop is roughly 2.5–3 cm thick, cooks in about 6 minutes total, and is at its best served pink (medium-rare to medium). That combination of speed and tenderness is exactly why they make such a reliable weeknight dinner.
Ingredients
Serves 2 (scale up easily for more).
- 4 lamb loin chops (about 500–600 g total), roughly 2.5–3 cm thick
- 1 tbsp olive oil
- 1 large knob of butter (about 25 g)
- 2 garlic cloves, lightly crushed (skin on)
- 2 sprigs fresh rosemary (or thyme)
- Sea salt and freshly ground black pepper
Optional 10-minute marinade: 1 tbsp olive oil, 1 crushed garlic clove, 1 tsp chopped rosemary, zest of half a lemon, a pinch of salt. Rub over the chops and leave at room temperature while the pan heats.
How to cook lamb loin chops
- Take the chops out of the fridge early. Let them sit at room temperature for 20–30 minutes before cooking. Cold meat straight from the fridge sears unevenly and overcooks at the edges.
- Dry and season. Pat the chops dry with kitchen paper — a dry surface is what gives you a proper crust. Season generously with salt and pepper on both sides just before cooking.
- Get the pan really hot. Heat the olive oil in a heavy frying pan or cast-iron skillet over medium-high heat until it shimmers. A hot pan is non-negotiable for a good sear.
- Sear the flat sides. Lay the chops in the pan and don’t move them. Sear for about 3 minutes until deeply browned, then flip and sear the other side for 2–3 minutes.
- Render the fat strip. Using tongs, stand the chops on their fatty edge for about 1 minute so the fat renders and crisps. This step is where a lot of the flavour lives.
- Add butter, garlic and herbs, then baste. Drop in the butter, crushed garlic and rosemary. As the butter foams, tilt the pan and spoon the aromatic butter over the chops for about 1 minute.
- Check the temperature and rest. For medium-rare, pull the chops at an internal temperature of 57–60°C (they’ll rise a few degrees while resting). Rest on a warm plate for 5 minutes before serving — this lets the juices redistribute so they don’t run out when you cut in.
Timings and doneness
- Prep time: 10 minutes (plus 20–30 minutes to come to room temperature)
- Cook time: 8 minutes
- Rest time: 5 minutes
- Total: about 25 minutes active
A meat thermometer takes the guesswork out of it. Pull the chops a few degrees below your target because they keep cooking as they rest:
- Rare: 52–54°C
- Medium-rare (recommended): 57–60°C
- Medium: 63–65°C
- Well done: 70°C and above (lamb loin loses tenderness here, so I don’t recommend it)
My kitchen tips
- Dry chops, hot pan, no fiddling. The three things that make or break the crust. If you move the chops around, they steam instead of sear.
- Don’t crowd the pan. Cook in two batches if your pan is small. Too many chops at once drops the temperature and you lose the sear.
- Save the resting juices. Whatever collects on the plate while the chops rest, spoon it back over at the end. It’s pure flavour.
- Deglaze for an instant sauce. After resting, add a splash of red wine or stock to the hot pan, scrape up the brown bits, and let it bubble for a minute for a quick pan sauce.
What to serve with lamb loin chops
Lamb loin chops are rich, so they like something fresh or starchy alongside. My go-to pairings are crushed new potatoes with mint, buttered green beans, a simple rocket salad, or a spoonful of minted yoghurt. For a slower-cooked lamb option on another night, my slow roasted lamb chops use the oven instead of the pan, and the pot roasted lamb shank is the one for cold evenings when you want something falling off the bone.
Frequently asked questions
What is the best way to cook lamb loin chops?
The best way to cook lamb loin chops is a quick, high-heat pan-sear: get a heavy pan very hot, sear each flat side for 2–3 minutes, render the fatty edge, then baste with butter, garlic and rosemary. Pull them at 57–60°C for medium-rare and rest for 5 minutes. The whole cook takes under 10 minutes.
How long do you cook lamb loin chops?
For chops about 2.5–3 cm thick, cook for roughly 3 minutes on the first side, 2–3 minutes on the second, plus about 1 minute on the fatty edge and 1 minute basting — around 8 minutes total. Always rest for 5 minutes afterwards.
Should lamb loin chops be pink in the middle?
Yes. Lamb loin is a tender cut and is at its best served medium-rare to medium, with a warm pink centre. Cooking it well done dries it out and makes it tougher. Aim for an internal temperature of 57–60°C for medium-rare.
Do you need to marinate lamb loin chops?
No — lamb loin chops are flavourful enough to cook with just salt, pepper and butter. A short 10-minute marinade of olive oil, garlic, rosemary and lemon zest is a nice optional upgrade, but anything longer isn’t necessary for such a tender cut.
Can you cook lamb loin chops from frozen?
It’s best to thaw them fully first. Searing from frozen gives you an overcooked grey band around the edge before the centre is done. Defrost overnight in the fridge, then bring to room temperature for 20–30 minutes before cooking.
Once you’ve got the sear-baste-rest rhythm down, lamb loin chops become one of the fastest impressive dinners in your repertoire. Cook them once with a thermometer and you’ll know exactly where your pan and your timing land — after that, you’ll be doing it by feel.
