Preheat your oven to 400 degrees. Next, make your yogurt sauce by blending your cilantro and dill first until chopped. Add your yogurt, lime juice, garlic, oil and salt and pepper. Blend and set aside.
To make your lamb, mix za’atar, sumac, paprika, pepper, salt, garlic powder and oil in a bowl. Spread the mixture all over the lamb and let marinate for 30mins-overnight.Heat a skillet with a drizzle of oil and let it get really hot. Sear your lamb for 5-6 minutes on each side until charred on medium-high heat.
After, place in the oven for 15-20 minutes. Let rest for 10-15 minutes and slice to make into chops. Serve with your herb yogurt sauce.
