Heat olive oil in a large skillet over medium heat.
Season chicken with half the thyme, salt, and pepper.
Cook chicken for 6–7 minutes per side until golden and fully cooked (internal temperature 165°F / 74°C).
Transfer chicken to a plate, leaving drippings in the skillet.
Add green beans, garlic, remaining thyme, and salt to the skillet.
Add water and stir to deglaze the pan.
Cover and cook for 4–5 minutes until beans are crisp-tender.
Meanwhile, prepare brown rice according to package instructions.
Divide rice among plates, top with chicken and green beans.
This Garlic Thyme Chicken with Rice is best served warm for maximum flavor.
