Rinse the basmati rice under cold water until clear, then combine with 0.5 cup of water in a small pot, bring to a boil, cover, and simmer for 15 minutes.
While the rice cooks, dice the chicken breast into 1-inch cubes and season them with the sea salt and black pepper.
Heat the ghee in a large skillet over medium-high heat and add the diced chicken, searing until golden brown on all sides, then remove chicken from the pan and set aside.
In the same skillet, add the finely chopped yellow onion and sauté for 3-4 minutes until translucent.
Stir in the minced garlic and grated fresh ginger, cooking for another minute until fragrant.
Add the garam masala and turmeric to the skillet, stirring constantly for 30 seconds to toast the spices.
Pour in the tomato puree and return the chicken to the pan, stirring to coat.
Reduce the heat to low and simmer the sauce for 8-10 minutes until the chicken is cooked through and the flavors have melded.
Stir in the full-fat coconut milk to create a creamy, orange sauce and heat through for 1 minute.
Fluff the cooked basmati rice with a fork and plate it alongside the chicken tikka masala.
Garnish the dish with fresh chopped cilantro before serving.
