Pan-Seared Lamb Loin Chops with Rosemary-Garlic Ghee and Lemon-Thyme Pan Reduction

Pat the lamb loin chops thoroughly dry with paper towels; this is crucial for achieving a superior sear. Season generously with flaky sea salt and freshly cracked black pepper.

Heat a heavy-bottomed skillet (preferably cast iron) over high heat until it just begins to smoke lightly. Add 30g of the ghee, the rosemary sprigs, and the smashed garlic cloves. Allow the garlic to gently roast in the ghee, infusing the fat with its aromatic essence, taking care not to burn it.

Carefully place the lamb chops into the hot skillet. Sear undisturbed for 3-4 minutes per side, depending on thickness, to develop a deep, burnished Maillard crust. The fat should render and crisp beautifully. For a medium-rare finish, the internal temperature should reach 54-57°C (130-135°F).

Once seared to your preferred doneness, remove the lamb chops from the skillet and transfer them to a warm plate. Tent loosely with foil and allow them to rest for at least 5-7 minutes. This allows the juices to redistribute, ensuring a tender and succulent chop.

While the lamb rests, prepare the pan reduction. Pour off any excess fat from the skillet, leaving just the flavorful fond. Add the bone broth, red wine vinegar, and fresh thyme sprigs to the hot pan. Bring to a rapid simmer, scraping up all the browned bits from the bottom of the pan with a wooden spoon. This is where immense umami lies.

Reduce the liquid by half or more, until it coats the back of a spoon. The reduction should be intensely flavored and slightly viscous. Remove the thyme sprigs. Stir in the remaining 15g of ghee and the juice and zest of half a lemon. Season with a tiny pinch of salt and pepper if needed, tasting carefully as the broth is already concentrated.

Carve the rested lamb loin chops against the grain into thick slices, or serve whole. Spoon the aromatic lemon-thyme pan reduction generously over the chops. Garnish with a fresh sprig of thyme or a whisper of lemon zest for an added layer of freshness.
