In a large pot, or a Le Creuset cocotte as pictured, add rice, water, broccoli, carrots, chicken bouillon, olive oil, salt, and water. Sprinkle half of dried spices.
Place chicken thighs on top, sprinkle remaining half of dried spices over the chicken. Cook on medium heat, covered with lid, until chicken thighs are cooked through.
Remove chicken thighs and place on a chopping board. Slice into chunks.
Stir the ingredients in the pot. Place chicken thigh chunks back into the pot.
Cook until rice is fully cooked through. Stir in milk and mozzarella cheese. The dish should be creamy and ready to be served hot.
