Season the chicken chunks with salt, pepper, cinnamon, and nutmeg, then set aside.
Heat olive oil in a large skillet over medium heat, then add the seasoned chicken. Cook until golden brown on all sides, about 5 minutes, then transfer to the slow cooker.
Add the sliced apples and cubed potatoes to the slow cooker around the chicken.
Pour the chicken broth over the ingredients, ensuring everything is partially submerged.
Cover the slow cooker and set it to low. Let it cook for 6 hours, allowing the flavors to meld and the chicken to become tender.
Once cooking is complete, gently stir the stew to combine the ingredients and check the seasoning, adjusting if needed.
Serve the stew hot, garnished with fresh herbs if desired, and enjoy the hearty, fragrant dish.
