Prepare the Chermoula Marinade: Lightly toast the cumin seeds until fragrant. Grind them in a food processor, before adding the garlic, onion, coriander, parsley, lemon zest and juice, black pepper, and smoked paprika. Blend until smooth.
Marinate the Chicken: Spoon the chermoula marinade over the chicken legs and massage it in. Leave to marinate for as long as you can – preferably overnight, but a couple of hours will do.
Preheat the Oven: When you’re ready to cook, heat the oven to 180C / 375F.
Roast the Chicken: Transfer the marinated chicken to a foil-lined roasting dish, and cook for 45 to 50 minutes, basting once or twice.
Prepare the Vegetables: Meanwhile, combine the beets and onion in a roasting dish. Toss in the olive oil and lemon juice, and sprinkle over the cumin seeds, salt, and pepper. Roast for 40 minutes.
Add the Tomatoes: After 40 minutes, add the cherry tomatoes to the roasting dish with the beets and cook for an additional 10 minutes.
Serve: Serve the roasted chicken legs alongside the cumin roasted beets and tomatoes. Enjoy the aromatic and earthy flavours of this North African-inspired dish.
