Choose a fresh, quality cut of lamb. Look for good marbling and a pinkish-red color. Rinse and pat dry. Season with salt, pepper, rosemary, garlic, or other preferred herbs and spices.
Preheat a skillet, grill, or oven (if roasting a leg) over medium-high heat. Add oil, or if using an oven, prepare a roasting pan with a rack. Ensure a good, even heat.
For chops: Sear on both sides for 2-3 minutes, then cook to desired doneness, 4-6 minutes for medium-rare.For leg: Roast in a preheated oven at 325°F (163°C) until it reaches an internal temperature of 145°F (63°C) for medium-rare, approximately 20 minutes per pound.
Remove the lamb from heat and let it rest for at least 5-10 minutes, allowing juices to redistribute. Carve against the grain, if applicable, and serve with desired accompaniments.
Lamb pairs wonderfully with roasted potatoes, sautéed greens, or a mint sauce. Consider a robust red wine like Cabernet Sauvignon or a refreshing white like Sauvignon Blanc.
