Olive oil, lemon juice, lemon zest, parsley, mint, onions, garlic, and salt should all be mixed together in a medium-sized bowl. Put it in the fridge until you're ready to serve.
Add the salt, pepper, garlic, and paprika to a big bowl and toss the leg of lamb around in it. If you want, you can let the lamb sit at room temperature for 30 minutes before cooking them.
Build a small fire with grate for skillet and allow to burn to glowing embers. Warm up the olive oil in the big cast iron dutch oven over medium-high heat. When the pan is hot, add about leg of lamb. Sear for two to four minutes, based on how done you want it.
When the outside of the lamb is a deep brown color, flip it over.
Turn the leg over so that the fat side is facing up (see picture above) and render the fat for about one minute.
For about 5 minutes, let the lamb chops rest. Put the sauce on top.
