In a bowl, I whisk together harissa paste, olive oil, lemon zest, lemon juice, garlic, cumin, salt, and pepper. I coat the chicken thighs completely in this mixture, working it under the skin too. If I have time, I let it sit for 30 minutes, but even a quick 10-minute marinate still packs plenty of flavor.
I heat my skillet over medium-high and place the chicken skin-side down first. This gets the skin crackling crisp in about 6 minutes. I flip it over, lower the heat slightly, and let it cook through until it hits 165°F internally, which takes another 10 to 12 minutes.
While the chicken rests, I toss the zucchini slices in a little olive oil, salt, and pepper. I lay them on a hot, dry grill pan or skillet and let them sit untouched for a few minutes per side. This is what gives them those deep, smoky char marks without turning mushy.
I bring the chicken broth to a boil in a saucepan, then stir in the couscous, cover it, and take it off the heat completely. After 5 minutes of resting, I fluff it with a fork so every grain separates nicely instead of clumping together.
I fold the toasted almonds and chopped parsley into the warm couscous, then plate it as the base. I top it with the charred zucchini and rest the harissa chicken thighs right on top. A final drizzle of yogurt and a squeeze of lemon finishes the whole plate.
