01 - In a large mixing bowl, whisk together 2 tablespoons olive oil, fresh lemon juice, minced garlic, smoked paprika, ground cumin, dried oregano, kosher salt, and black pepper until well combined.
02 - Add the boneless chicken thighs to the marinade, tossing to coat each piece evenly. Cover and refrigerate for at least 15 minutes to allow the flavors to penetrate.
03 - Heat a large skillet over medium-high heat. Remove the chicken from the marinade and place in the hot skillet. Cook for 6 to 7 minutes per side until deeply golden brown and the internal temperature reaches 165°F. Transfer to a plate and let rest for 5 minutes.
04 - In the same skillet, add 1 tablespoon olive oil. Sauté the minced garlic for 30 seconds until fragrant. Add the sliced zucchini and cook for 3 to 4 minutes, stirring frequently, until just tender but still bright green.
05 - Stir in the lemon zest, fresh lemon juice, chopped parsley, and season with salt and pepper. Sauté for 1 additional minute, then remove from heat.
06 - Arrange the lemon zucchini sauté on a serving platter. Slice or place the rested asado chicken thighs on top. Garnish with additional fresh parsley and lemon wedges if desired.
