Grilled garlic and herb lamb loin chops start with 2 pounds of lamb loin chops marinated in olive oil, garlic paste, rosemary, thyme, lemon zest, lemon juice, and Pappy’s Prime Rib Seasoning for at least 1 hour (overnight for the deepest flavor), then seared fat-side down first in a cast iron skillet to render the fat cap crispy before searing all remaining sides for a deep crust. After the sear, the chops finish in a 375°F oven or on the smoker until they hit 135°F internal for medium-rare. A fresh chimichurri sauce made from parsley, garlic, oregano, red pepper flakes, red wine vinegar, and olive oil goes on during the rest and on the side for serving. Serves 4.

Why Lamb Loin Chops Are Worth Cooking at Home
A T-Bone Steak in Miniature
Lamb loin chops are cut from the saddle of the lamb and have a small T-bone running through the center, with the loin on one side and a small piece of tenderloin on the other. They are essentially the lamb equivalent of a T-bone steak, with two different textures of meat in every chop. The loin side is lean and firm, while the tenderloin side is softer and more delicate. Both sides benefit from the high-heat sear and gentle finish that this recipe uses.
Available at Most Grocery Stores
Unlike rack of lamb, which can be expensive and harder to find, lamb loin chops are available in the butcher case of most grocery stores at a more accessible price point. They cook quickly (under 10 minutes of active cooking time), they are forgiving if you slightly overcook them, and they look impressive on the plate despite being one of the simplest proteins to prepare. Eight chops from a 2-pound pack feeds four people generously.
Building the Garlic and Herb Marinade
Olive Oil, Garlic Paste, and Fresh Herbs
The marinade combines 1/2 cup olive oil, 4 garlic cloves minced into a paste, 1 teaspoon rosemary, 1 teaspoon thyme, the zest and juice of 1 lemon, and your seasoning of choice. The olive oil carries the garlic and herb flavors into the surface of the lamb during the marinating time, while the lemon juice adds acidity that tenderizes the outer layer of the meat and brightens the overall flavor. Using garlic paste (or mincing the garlic very finely) ensures even distribution across every chop.
Marinate at Least 1 Hour, Overnight for Best Results
Coat the lamb loin chops evenly with the marinade, making sure all sides are covered. Cover and refrigerate for at least 1 hour so the garlic, herbs, and lemon have time to penetrate the surface. Overnight marinating produces a deeper flavor and a more pronounced herb aroma when the chops hit the hot pan. The lemon juice also helps break down the surface proteins slightly, which means the sear develops faster and more evenly during cooking.
Searing Fat-Side Down First
Render the Fat Cap Before Searing the Faces
Lamb loin chops have a strip of fat along one edge that needs to be rendered and crisped before you sear the flat faces of the chop. Place each chop fat-side down in a hot cast iron skillet or grill pan and hold it in position for 1 to 2 minutes until the fat turns golden brown and crispy. Rendering the fat first accomplishes two things simultaneously. It crisps the fat cap into a flavorful, crunchy edge instead of leaving it soft and chewy, and it releases rendered lamb fat into the pan that you can use to sear the remaining sides.
Sear All Sides for a Deep Crust
After the fat cap is rendered, lay the chops flat and sear each side for 2 to 3 minutes until a deep, golden-brown crust forms. The garlic and herbs in the marinade caramelize during the sear and create a fragrant, flavorful exterior. Do not move the chops during each sear, as lifting them too early breaks the crust before it has time to form and release from the pan surface.
Finishing in the Oven or on the Smoker
375°F to Medium-Rare at 135°F
After searing, transfer the lamb chops to a 375°F oven or smoker to finish cooking gently until the internal temperature reaches 135°F for medium-rare. The sear built the crust, and the lower, indirect heat of the oven or smoker brings the interior up to temperature without overcooking the exterior. Lamb loin chops are best at medium-rare because the fat stays soft and rich at this temperature. Cooking beyond medium (140°F+) causes the intramuscular fat to firm up and turn waxy, which makes the chop taste dry and gamey instead of tender and rich.
Rest 5 to 10 Minutes Before Serving
Pull the chops at 135°F and let them rest for 5 to 10 minutes. Carryover heat will bring the internal temperature up another 3 to 5 degrees during the rest. While they rest, brush them lightly with the chimichurri sauce so the herbs and olive oil adhere to the warm surface. The rest also allows the juices to redistribute through the meat, which means the first bite is juicy and tender instead of dry from the juices running out onto the plate.
Fresh Chimichurri as the Finishing Sauce
Bright, Herbaceous, and Acidic
The chimichurri combines 1 cup fresh parsley, 3 minced garlic cloves, 2 tablespoons fresh oregano, 1/2 teaspoon red pepper flakes, 2 tablespoons red wine vinegar, 1/2 cup olive oil, and salt and pepper. Mix everything together and let it sit while the lamb cooks so the olive oil absorbs the garlic and herb flavors. The bright acidity from the red wine vinegar cuts through the richness of the lamb fat, and the fresh parsley and oregano add a clean, herbaceous finish that lightens every bite.
Brush On and Serve Extra on the Side
Brush a light coat of chimichurri over the resting lamb chops so the herbs and oil meld with the warm surface. Serve the remaining chimichurri on the side so each person can add as much as they want. The chimichurri also keeps in the fridge for up to 2 days, though it tastes best when freshly made because the herbs are at their brightest and most vibrant.
Step-by-Step: How to Make Grilled Garlic and Herb Lamb Loin Chops
Step 1: Marinate the Lamb
In a bowl, combine 1/2 cup olive oil, 4 garlic cloves minced into a paste, 1 teaspoon rosemary, 1 teaspoon thyme, the zest and juice of 1 lemon, and 1 tablespoon Pappy’s Prime Rib Seasoning (or 1 teaspoon each of salt, black pepper, and garlic powder). Mix until fully combined, then coat all 8 lamb loin chops evenly on all sides. Cover and refrigerate for at least 1 hour, or overnight for the deepest flavor.
Step 2: Make the Chimichurri
Combine 1 cup chopped fresh parsley, 3 minced garlic cloves, 2 tablespoons fresh oregano, 1/2 teaspoon red pepper flakes, 2 tablespoons red wine vinegar, 1/2 cup olive oil, and salt and pepper to taste. Mix well and set aside so the flavors blend together while the lamb cooks.
Step 3: Sear Fat-Side Down, Then All Sides
Heat a cast iron skillet or grill pan over medium-high heat. Place the lamb chops fat-side down first and hold them in position for 1 to 2 minutes until the fat cap is golden brown and crispy. Then lay each chop flat and sear 2 to 3 minutes per side until a deep, golden-brown crust develops on all surfaces.
Step 4: Finish at 375°F
Transfer the seared chops to the smoker or a 375°F oven and cook until the internal temperature reaches 135°F for medium-rare. This takes roughly 5 to 8 minutes depending on thickness. The indirect heat finishes the interior gently without overcooking the seared exterior.
Step 5: Rest, Brush with Chimichurri, and Serve
Let the lamb chops rest for 5 to 10 minutes. While they rest, brush them lightly with the chimichurri sauce so the herbs and olive oil adhere to the warm surface. Serve with extra chimichurri on the side for dipping.

Common questions about lamb loin chops, marinating, searing technique, and chimichurri.
Your Questions, Answered
Lamb loin chops are cut from the saddle of the lamb and have a small T-bone running through the center with the loin on one side and a small piece of tenderloin on the other. They are essentially the lamb equivalent of a T-bone steak. You can find them in the butcher case of most grocery stores, and they cook quickly since they are relatively thin.
Lamb loin chops have a strip of fat along one edge that needs to be rendered and crisped before searing the flat faces. Starting fat-side down for 1 to 2 minutes crisps the fat cap into a flavorful, crunchy edge instead of leaving it soft and chewy. It also releases rendered lamb fat into the pan, which you then use to sear the remaining sides for a deeper crust.
Yes. Lamb rib chops (sometimes labeled “petite” or “small”) work well with this same marinade and technique. Rib chops are slightly smaller and have a single round eye of meat with a protruding rib bone, while loin chops have the T-bone with two sections of meat. Rib chops cook a few minutes faster, so watch the internal temperature closely and pull at 135°F.
Searing builds the crust, but continuing to cook at high heat in the pan would overcook the exterior before the center reaches medium-rare. Transferring to a 375°F oven or smoker uses lower, indirect heat to bring the interior up to 135°F gently without burning the garlic and herbs in the marinade or drying out the outer layer of the chop.
Doneness and Serving
At medium-rare, the intramuscular fat in lamb stays soft and rich, which keeps the meat tender and flavorful. Cooking beyond medium (140°F+) causes the fat to firm up and turn waxy, which makes the chop taste dry and gamey rather than succulent. Carryover heat during the rest will bring the temperature up another 3 to 5 degrees, so pulling at 135°F finishes around 138 to 140°F after resting.
Yes. The chimichurri keeps in the fridge for up to 2 days in an airtight container, though it tastes best when freshly made because the herbs are at their brightest. If making ahead, bring it to room temperature before serving so the olive oil flows freely and the flavors are more pronounced. The color will darken slightly overnight, but the flavor remains excellent.
Lamb pairs well with roasted potatoes, grilled asparagus, couscous, or a simple arugula salad with lemon vinaigrette. Grilled vegetables like zucchini, bell peppers, and eggplant complement the Mediterranean herb profile of the marinade and chimichurri. Keep the sides relatively neutral so the garlic, herb, and lemon flavors of the lamb remain the focal point.
