01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper or foil for easy cleanup.
02 - In a large bowl, whisk together olive oil, oregano, thyme, smoked paprika, garlic, salt, and pepper until well combined.
03 - Add chicken thighs to the bowl and toss to coat thoroughly with the marinade, ensuring even coverage.
04 - Place the chicken thighs on the prepared sheet pan, skin side up, leaving space for vegetables around the edges.
05 - Scatter red onion, bell pepper, artichoke hearts, olives, and lemon slices around and underneath the chicken pieces.
06 - Drizzle any remaining marinade from the bowl over the vegetables for additional flavor.
07 - Roast in the preheated oven for 35 minutes, or until the chicken skin is golden and crispy and the internal temperature reaches 165°F.
08 - Remove from the oven, sprinkle with fresh chopped parsley, and serve hot directly from the pan.
