In a large bowl, whisk together harissa paste, honey, olive oil, lemon juice, minced garlic, cumin, coriander, smoked paprika, salt, and pepper to create the marinade.
Add the chicken thighs to the bowl and toss to coat evenly with the marinade.
Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or overnight for best results.
Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper or aluminum foil.
Remove the chicken from the marinade and arrange the pieces on the prepared baking sheet.
Bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
For extra caramelization, broil for an additional 2-3 minutes.
Remove from the oven and let the chicken rest for 5 minutes before serving.
Slice the chicken and serve with your choice of sides.
