In a medium mixing bowl, whisk together 2 tablespoons of olive oil, minced garlic, lemon zest, lemon juice, dried oregano, dried thyme, ground cumin, and a generous pinch of salt and pepper. Add the chicken breasts to the bowl, ensuring they are thoroughly coated in the marinade. Cover the bowl with plastic wrap and let it marinate in the refrigerator for at least 30 minutes, or for up to 2 hours to enhance the flavor.
In a medium saucepan, bring the chicken broth to a rolling boil over medium-high heat. Once boiling, remove the pan from the heat and stir in the couscous. Cover the saucepan with a lid and let it sit for approximately 5 minutes, allowing the couscous to absorb the liquid. After the time is up, fluff the couscous with a fork to separate the grains and set it aside.
In a large skillet, heat the remaining tablespoon of olive oil over medium heat. Once the oil shimmers, add the marinated chicken breasts to the skillet. Cook the chicken for about 5-7 minutes on each side, or until it reaches a golden brown color and an internal temperature of 165°F (75°C). Once cooked, transfer the chicken to a cutting board and let it rest for a few minutes before slicing into strips.
In a large mixing bowl, combine the fluffed couscous with any remaining marinade that was drizzled off the chicken. Taste and adjust the seasoning with additional salt and freshly ground pepper if needed. Fold in the chopped parsley gently to enhance the fresh flavor.
Layer the sliced chicken on top of a generous bed of lemon herb couscous. Garnish with extra chopped parsley and lemon wedges for a burst of freshness and color. Serve immediately for a delightful, bright presentation.
Notes
Let the chicken marinate for up to 2 hours for enhanced flavor.
