Pat the chicken dry with paper towels, season with salt, black pepper, paprika, and garlic powder. Dredge lightly in flour.
In a large skillet over medium heat, melt butter. Sear chicken thighs skin-side down for 4–5 minutes on each side until golden. Remove and set aside.
In the same skillet, sauté chopped onions until translucent, about 3–4 minutes. Add minced garlic and cook for an additional 30 seconds.
Sprinkle in two tablespoons of flour over the onion and garlic mixture. Cook for one minute while stirring to form the roux.
Gradually whisk in chicken broth, ensuring no lumps. Add heavy cream and simmer until slightly thickened.
Return seared chicken to the pan with gravy. Cover and simmer on low heat for 25–30 minutes.
Cook white rice according to package directions while chicken simmers.
Serve chicken thighs drenched in gravy over cooked rice, garnished with fresh parsley.
