Pat chicken thighs dry. Season both sides with salt, pepper, and garlic powder.
Heat a large skillet over medium-high heat. Add vegetable oil and butter; let the butter melt.
Add chicken thighs in a single layer. Sear 3–5 minutes per side until browned.
Add fresh garlic to the pan, then carefully pour in the water.
Cover, reduce heat to medium, and cook 8–12 minutes or until chicken reaches 165°F (74°C).
Uncover and simmer 1–3 minutes to reduce into a glossy sauce, spooning sauce over chicken.
Serve hot with pan sauce.
