Preheat the oven: Start by preheating your oven to 400°F (200°C) to ensure it’s ready when you're done preparing the chicken.
Mix the marinade: In a medium-sized bowl, whisk together 1/4 cup olive oil, 2 tbsp harissa paste, 2 tbsp honey, 2 cloves garlic, minced, 1 tsp ground cumin, 1 tsp ground coriander, 1/2 tsp smoked paprika, and 1/2 tsp salt until well combined. The mixture should be smooth and fragrant.
Coat the chicken: Place the 4 boneless, skinless chicken breasts in a large baking dish. Pour the harissa mixture over the chicken, ensuring each piece is generously coated on all sides. Let it marinate for at least 10 minutes to let the flavors mingle, allowing the chicken to absorb the marinade.
Bake the chicken: Transfer the baking dish to the preheated oven. Bake for 20-25 minutes or until the chicken is cooked through. To check for doneness, the juices should run clear, and the internal temperature should reach 165°F (75°C). During baking, you can spoon the flavored juices from the bottom of the dish over the chicken to help keep it moist.
Serve: Once cooked, remove the chicken from the oven and let it rest for a few minutes before slicing. This lets the juices redistribute, ensuring maximum flavor and moisture. Serve hot with your favorite sides!
