Cut the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
Heat the ghee in a large skillet over medium-high heat until melted and shimmering.
Add the chicken pieces to the skillet and sear until golden brown on all sides, then remove the chicken and set aside on a plate.
In the same skillet, add the finely chopped yellow onion and sauté for 3-4 minutes until translucent and soft.
Stir in the minced garlic, grated fresh ginger, garam masala, turmeric, and cumin, cooking for 1 minute until highly fragrant.
Pour in the tomato puree and stir to combine, allowing the sauce to simmer for 5 minutes on medium-low heat until it thickens.
Whisk in the full-fat coconut milk to create a creamy orange sauce, then return the seared chicken and any juices to the pan.
Simmer for an additional 3-5 minutes until the chicken is fully cooked through and the sauce is glossy.
Garnish with freshly chopped cilantro and serve warm.
