Pat the chicken thighs dry and season with paprika, Italian seasoning, garlic powder, salt, and black pepper.
Melt 1 tablespoon butter in a large skillet over medium-high heat. Sear the chicken for about 4 minutes per side until golden, then transfer to a plate.
Reduce heat to medium. Add the remaining butter and onion. Cook for 2–3 minutes.
Add the minced garlic and cook for about 30 seconds.
Add the rice and stir for 1 minute to coat it in the garlic butter.
Pour in the chicken broth and bring to a gentle simmer.
Return the chicken to the skillet. Cover and cook over low heat for 18–22 minutes, until the rice is tender and the chicken reaches 165°F (74°C).
Remove from heat and rest covered for 5 minutes.
Fluff the rice, garnish with parsley, and serve with fresh lemon wedges.
