Preheat your grill or a grill pan to medium-high heat. Brush the grill grates with oil to prevent sticking.
Grill the marinated lamb backstraps for about 4-5 minutes per side for medium-rare, or adjust the cooking time to your desired level of doneness. Cooking times may vary depending on the thickness of the backstraps and the heat of your grill. Use a meat thermometer to ensure they reach your preferred internal temperature (about 130-135°F or 54-57°C for medium-rare).
While the lamb is grilling, prepare the sauce. In a separate saucepan, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion and sauté until it becomes soft and translucent.
Stir in the diced tomatoes, chopped cilantro, chopped parsley, dried apricots, and slivered almonds. Season with salt and black pepper to taste. Simmer the sauce for about 10-15 minutes, allowing the flavors to meld together.
Once the lamb backstraps are done grilling, remove them from the heat and let them rest for a few minutes before slicing.
To serve, slice the grilled lamb backstraps into thin slices and arrange them on a serving platter. Spoon the Moroccan-inspired sauce over the top. Garnish with additional chopped fresh cilantro and parsley if desired. Enjoy your Moroccan Lamb Backstrap with its flavorful marinade and delightful sauce! Serve it with couscous, rice, or flatbread for a complete meal.
