Marinate the chicken with salt, turmeric, cumin, and coriander powder for at least 30 minutes.
Heat a skillet, melt the butter, and cook the marinated chicken until browned.
Sauté minced garlic in the same skillet, then add pureed tomatoes and simmer.
Return the chicken to the skillet, add heavy cream, and simmer for an additional 10 minutes.
Preheat the oven and bake the frozen fries until golden brown and crispy.
Serve the butter chicken alongside the crispy fries, garnished with cilantro.
