Preheat your oven to 400°F for the roasted vegetables.
Season the lamb with salt, pepper, ground cumin, and ground coriander.
In a heavy skillet or Dutch oven, sear the lamb on medium-high heat until browned on all sides, about 2-3 minutes per side.
Add a splash of water or broth to the pan, reduce the heat, cover, and let the lamb braise for about 45 minutes until tender.
Meanwhile, peel and cut the carrot into bite-sized pieces, slice the zucchini into rounds, and cut the red onion into wedges.
Toss the vegetables in olive oil, salt, and pepper. Spread them on a baking sheet.
Roast the vegetables in the preheated oven for 20-25 minutes, until they are tender and slightly caramelized.
Plate the braised lamb alongside the roasted vegetables, garnish with fresh parsley, and serve warm.
