Batching

A double batch marinates in a larger container and fits most grills; grill in two rounds if the chops do not fit in one layer. Times and the 145°F (63°C) endpoint do not change with the amount.

Original recipe: 6 servings.

Extra salt at serving is left out of the base nutrition scenario. The marinade is thrown away, so its eaten share is not counted.

Before you start

  • Read through the recipe before you start; the chops marinate for about two hours. Gather the covered container, grill, tongs, a clean plate, the thermometer and the measured ingredients.

Directions

Six raw lamb loin chops sit on a tray beside sliced onion and an empty container.
1

Read and gather

For the whole recipe

Read through the recipe and gather the equipment. Use the ingredient lines to prepare and measure everything, and wash your hands after handling the raw lamb. Everything is measured and the container is ready.

2

Stir the marinade and marinate the chops

For the whole recipe

Stir the onion, 1/4 cup distilled white vinegar, 2 tbsp olive oil, 1 tbsp garlic, 2 tsp fine salt and 1/2 tsp black pepper together in the container. Turn 6 whole lamb loin chops in the mixture until the chops are well coated. Cover and refrigerate them, about 2 hours.

3

Heat the grill and drain the chops

For the whole recipe

Heat the grill to medium-high heat. Lift the chops out of the marinade, letting any onion slices that cling stay on, and throw the used marinade away; it is never reused raw. The grill is hot and the chops are drained.

4

Grill the chops to temperature

For the whole recipe

Grill the chops over medium-high heat, turning them once, until they are well marked and browned on both sides, about 6 minutes in all. Check the meat away from the bone with an instant-read thermometer: it reads 145°F (63°C).

Move the chops to a clean plate and let them rest

For the whole recipe

Move the chops to the clean plate and let them rest for at least three minutes, the USDA rest for whole cuts of lamb. The chops have rested for at least three minutes.

Taste and serve

For the whole recipe

Taste a bite. Aim for savory lamb with a light tang from the marinade. If it tastes flat, sprinkle fine salt to taste over the chops. Serve them to make 6 servings, and refrigerate leftovers within two hours. The chops are seasoned and ready to serve.

About this recipe

Why it works

A short marinade of vinegar, salt, onion and garlic seasons the chops and adds tang; hot, direct grilling browns the outside quickly, and resting after 145 °F lets the juices settle.

Serving and keeping

Best served: Right after the 3-minute rest With any onion slices that cling to the chops

Make ahead: Grill the chops when you plan to eat them.

Storage: Refrigerate cooked chops within 2 hours (1 hour above 90 °F / 32 °C), covered. They freeze for about 2 to 3 months for best quality.

Leftovers: Slice leftover lamb thinly and serve it cold, or reheat gently.

Food safety

  • Marinate the chops covered in the refrigerator, not on the counter.
  • Throw away the used marinade; it held raw meat, so it is not used as a sauce.
  • Put the cooked chops on a clean plate, not the one that held them raw.
  • Check the meat away from the bone with a food thermometer: 145 °F (63 °C), then a 3-minute rest.

We make no statement about cross-contact in your kitchen or in packaged ingredients. Check the vinegar label.

Nutrition notes

Most of the salt stays in the discarded marinade, but some is absorbed. Using half the salt lowers it.
