Preheat your oven to 400°F (200°C).
Pat the chicken thighs dry with paper towels to ensure crispiness. Season both sides with salt, pepper, garlic powder, and smoked paprika.
Heat olive oil in a large oven-safe skillet over medium-high heat. Once hot, add the chicken thighs skin-side down and sear for 5-7 minutes, or until the skin is golden and crispy.
Flip the chicken thighs and cook for an additional 3-4 minutes.
Transfer the skillet to the preheated oven and roast for 25-30 minutes, or until the internal temperature reaches 165°F (75°C).
While the chicken is roasting, prepare the lemon butter sauce. In a saucepan over medium heat, melt the butter.
Add the minced garlic to the melted butter and sauté for 1 minute until fragrant.
Stir in the chicken broth, lemon juice, and lemon zest, then bring to a simmer.
Reduce the heat to low and continue to simmer the sauce for 3-4 minutes, allowing the flavors to meld.
Remove the sauce from heat and stir in the chopped parsley. Season with salt and pepper to taste.
Once the chicken is done, let it rest for a few minutes before serving.
Drizzle the lemon butter sauce over the chicken thighs just before serving.
