Lamb chops are one of the fastest routes to a restaurant-style dinner at home: a hard sear for a golden crust, a garlic and rosemary butter baste, and a short rest so they stay juicy. The caramelized pearl onions alongside are sweet and savory at once, and they soak up the herb butter beautifully. It is an elegant plate that cooks in under half an hour.
Ingredients
For the rosemary lamb chops: 4–6 lamb rib chops (about 700 g); 3 tbsp unsalted butter; 2 tbsp olive oil; 4 garlic cloves, minced; 2 sprigs fresh rosemary; 3 sprigs fresh thyme; 1 tsp salt; ½ tsp freshly ground black pepper; ½ tsp smoked paprika; ½ tsp garlic powder; 1 tbsp fresh lemon juice; 1 tsp Dijon mustard (optional).
For the caramelized pearl onions: 250 g pearl onions, peeled; 2 tbsp unsalted butter; 1 tbsp olive oil; 1 tsp honey; ¼ cup chicken or beef broth; ½ tsp salt; ¼ tsp black pepper; 1 tsp fresh thyme leaves.
For the garlic herb butter sauce: 2 tbsp unsalted butter; 2 garlic cloves, finely minced; 1 tsp fresh rosemary, chopped; 1 tsp fresh thyme, chopped; 1 tbsp lemon juice; 2 tbsp beef broth; a pinch of black pepper.
For garnishing: 1 tbsp fresh parsley, finely chopped; fresh rosemary sprigs; a pinch of flaky sea salt.
Method
Start the onions: melt the butter with the olive oil in a pan over medium heat, add the pearl onions and salt, and cook for 10–12 minutes, stirring, until golden. Stir in the honey and broth, cover, and cook for 8–10 minutes more until tender and glazed. Stir in the thyme leaves and pepper.
Pat the lamb chops dry and season with salt, pepper, smoked paprika and garlic powder. Rub with the Dijon mustard if using.
Heat the olive oil in a heavy pan over high heat. Sear the chops for 3–4 minutes per side until deeply browned.
Lower the heat, add the butter, garlic, rosemary and thyme sprigs, and baste the chops with the foaming butter for 1–2 minutes. Splash in the lemon juice.
Cook until the chops reach 145°F (63°C), then rest for 5 minutes.
For the sauce, melt the butter in a small pan, soften the garlic for 30 seconds, then stir in the rosemary, thyme, lemon juice, beef broth and pepper, and simmer for 1 minute.
Serve the chops with the caramelized pearl onions, spoon over the herb butter sauce, and garnish with parsley, rosemary sprigs and flaky sea salt.
Cooking Tips
Dry chops and a very hot pan are what build the golden crust — wet meat steams instead of searing.
Resting for 5 minutes keeps the chops juicy; cutting straight from the pan loses the juices to the board.
Basting with the herb butter in the last minutes flavors the chops far more than marinating them briefly would.
Frequently asked questions
How do I peel pearl onions easily?
Blanch them in boiling water for 1 minute, then cool — the skins slip right off.
Can I use lamb loin chops instead of rib chops?
Yes — loin chops are meatier and cook the same way; just watch the temperature, as thicker chops need a minute or two longer.
