Cut the chicken breast into bite-sized cubes and season with sea salt and black pepper.
Heat the ghee in a large skillet over medium-high heat until melted.
Add the chicken cubes to the skillet and sear until golden brown on all sides, about 5-6 minutes.
Stir in the diced onion, minced garlic, and grated ginger, sautéing for 3 minutes until the onion is translucent.
Add the garam masala, turmeric, and cumin to the pan, stirring constantly for 1 minute to toast the spices.
Pour in the tomato puree and full-fat coconut milk, stirring well to combine with the chicken and aromatics.
Reduce the heat to low and simmer the sauce for 10-12 minutes until it thickens and the chicken is cooked through.
In a separate small pan, lightly sauté the cauliflower rice for 4-5 minutes until tender.
Plate the cauliflower rice and top with the creamy chicken tikka masala.
Garnish with chopped fresh cilantro before serving.
