In a large bowl, combine the minced garlic, lemon zest, lemon juice, olive oil, dried oregano, paprika, salt, and pepper. Add the chicken thighs and rub the marinade all over them. Let them marinate for at least 30 minutes (or up to overnight in the fridge for maximum flavor).
Preheat your oven to 425°F (220°C).
Place a wire rack on a baking sheet. This will allow heat to circulate around the chicken.
Once marinated, place the chicken thighs skin-side up on the wire rack. Roast in the preheated oven for about 30-35 minutes, or until the skin is crispy and the internal temperature reaches 165°F (75°C).
While the chicken is roasting, bring a pot of salted water to a boil. Add the green beans and cook for 3-4 minutes until bright green and tender-crisp. Drain and transfer to a large bowl of ice water to stop the cooking process. Once cooled, drain again and set aside.
In a skillet, melt the butter over medium heat. Add the green beans and sauté for about 3-4 minutes, stirring occasionally. Season with salt and pepper.
Once the chicken is done, remove it from the oven and let it rest for a few minutes. Serve the chicken thighs on a plate with a side of sautéed green beans. Garnish with chopped parsley for a pop of color.
Notes
For maximum flavor, marinate the chicken overnight.
