Preheat your oven to 400°F (200°C).
In a large oven-safe skillet, heat the olive oil over medium-high heat. Season the chicken thighs with salt, pepper, paprika, and thyme.
Once the oil is hot, add the chicken thighs skin-side down to the skillet. Sear for about 5-7 minutes until the skin is golden brown and crispy. Flip the chicken and cook for an additional 5 minutes.
Remove the chicken from the skillet and set aside. In the same skillet, add the butter and minced garlic. Sauté for about 1 minute until fragrant.
Add the green beans to the skillet and toss them in the garlic butter. Squeeze in the lemon juice and add the lemon zest. Stir to combine.
Nestle the chicken thighs back into the skillet on top of the green beans.
Transfer the skillet to the preheated oven and roast for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the green beans are tender.
Remove from the oven and let rest for a few minutes. Garnish with chopped parsley before serving.
