Pat chicken thighs dry and season both sides with garlic powder, paprika, salt, and pepper.
Coat with taco sauce and let sit 10–15 minutes (optional).
Heat oil in cast iron skillet over medium-high heat.
Cook thighs 5–6 minutes per side until golden brown and internal temp reaches 165°F.
Use a lid slightly ajar to reduce splatter (don’t fully cover).
Let rest for 5 minutes. Slice and serve as desired
