Prepare and marinate the chicken: Pat the chicken thigh pieces dry and place in a bowl. In a separate small bowl whisk together the harissa paste, lemon zest, lemon juice, minced garlic and 2 tablespoons of olive oil, plus a good pinch of sea salt and several grinds of black pepper. Toss the chicken in the marinade to coat thoroughly. Why: Patting dry helps the marinade stick and promotes better browning; the acid in the lemon brightens the chicken while harissa and garlic build depth. Marinating 30–60 minutes allows the flavors to infuse without 'cooking' the meat with acid.

Soak and prep skewers & carrots: If using wooden skewers, submerge them in water for 30 minutes to prevent burning. Meanwhile, using a vegetable peeler, shave the carrots into long ribbons (stop when you reach the core). Toss ribbons with a small pinch of salt, 1 teaspoon olive oil and a little cracked black pepper. Why: Soaked skewers resist flare-ups; thin carrot ribbons char quickly and develop a sweet, slightly smoky flavor without becoming mushy.

Thread the chicken onto skewers: Thread 4–5 pieces of marinated chicken onto each skewer, leaving a little space between pieces so heat circulates. Reserve the remaining marinade. Why: Crowding prevents even cooking and inhibits browning; leaving gaps ensures the hot air or flames can create a caramelized exterior.

Preheat your grill or grill pan: Heat a grill to medium-high (around 400°F / 200°C) or place a heavy grill pan over medium-high heat. Brush the grate or pan with the remaining 1 tablespoon of olive oil to prevent sticking. Why: A properly hot surface sears the exterior quickly, creating Maillard browning that adds flavor and locks in juices.

Start the couscous: Bring the stock to a simmer (hot) in a small saucepan. Place the dry couscous in a heatproof bowl, stir in 1/2 tsp salt, then pour the hot stock over it, cover tightly and let sit for 5 minutes. Why: Rehydrating couscous with hot, seasoned stock infuses flavor and produces light, separated grains quickly without stirring or boiling.

Grill the chicken skewers: Place the skewers on the hot grill or pan and cook 3–4 minutes per side, turning to get even char and a deep red-brown crust. During the last minute of cooking, baste with a spoonful of any reserved marinade (do not re-use raw marinade unless you bring it to a boil first) or a little extra olive oil. Chicken thighs should reach 74°C / 165°F internal temperature. Why: Short, hot cooking gives a crisp exterior; checking temperature ensures safe, juicy meat—thighs tolerate slightly longer cooking without drying out.

Char the carrot ribbons: While the chicken cooks, lay carrot ribbons on the grill or in a second hot pan in a single layer and let them blister and char 1–2 minutes per side until slightly softened and caramelized. Remove quickly to avoid overcooking. Why: Quick char concentrates the carrot's natural sugars and adds a smoky note that complements the harissa.

Finish the couscous: After the couscous has rested 5 minutes, remove the lid and fluff gently with a fork to separate the grains. Stir in the butter (if using) and chopped parsley, plus 1 teaspoon lemon zest and a squeeze of lemon juice to taste; season with salt and pepper. Why: Fluffing prevents clumping; butter or olive oil adds silkiness, and fresh herbs and lemon lift the neutral couscous to complement the bold chicken.

Plate and finish: Spoon a mound of herb couscous on each plate, top with 2 skewers of the grilled harissa-lemon chicken and a nest of charred carrot ribbons. Finish with a light dusting of sumac or a wedge of lemon and an extra drizzle of olive oil if desired. Taste and adjust salt and pepper. Why: Sumac or lemon provides a bright, slightly tart counterpoint to the smoky-spicy chicken, rounding the flavors and adding visual contrast.

Rest and serve: Let chicken rest 3–5 minutes off the heat before serving so juices redistribute. Serve with extra harissa on the side for heat lovers. Why: Resting yields juicier bites and prevents the juices from spilling out immediately when cut or bitten into.
