Roast the Lamb
Preheat oven to 200°C (390°F).
Toss lamb chunks with 1 tbsp olive oil, orange zest, salt, and pepper.
Roast for 15–20 minutes until browned.
Sauté Vegetables and Spices
In a large pot or Dutch oven, heat 1 tbsp olive oil.
Sauté onion, garlic, carrots, and red bell pepper until softened.
Stir in cumin, coriander, cinnamon, turmeric, and smoked paprika. Cook 1–2 minutes until fragrant.
Simmer the Stew
Add roasted lamb back to the pot along with chickpeas, chopped tomatoes, and stock.
Cover and simmer for 40–50 minutes until lamb is tender.
Add Zucchini
Stir in zucchini slices 10–15 minutes before the end of cooking. Cook until tender but still firm.
Prepare the Couscous
Boil water or stock with a pinch of salt and olive oil.
Pour over couscous in a bowl, cover, and let steam 5–10 minutes.
Fluff with a fork, then mix in parsley, mint, lemon juice, and toasted nuts.
Serve
Plate the couscous, spoon the lamb and vegetable stew on top.
Garnish with fresh herbs, a dollop of yogurt or labneh, and drizzle with chili oil if desired.
