Season the chicken breast with half of the sea salt and black pepper, then grill or pan-sear until the internal temperature reaches 165°F.
Slice the cooked chicken into thin strips and set aside while you prepare the rice.
In a wide skillet, heat the olive oil over medium heat and sauté the sliced mushrooms and minced garlic until they are golden and fragrant.
Add the Arborio rice to the skillet, stirring for 2 minutes to ensure each grain is lightly toasted and coated in oil.
Reduce the heat to medium-low and add 0.25 cup of warm bone broth, stirring constantly until the liquid is fully absorbed by the rice.
Continue adding the broth 0.25 cup at a time, stirring frequently for about 20 minutes until the rice is tender and has developed a creamy consistency.
Stir in the remaining sea salt, black pepper, and parmesan cheese until the cheese is completely melted and the sauce is smooth.
Divide the risotto into bowls, top with the sliced chicken strips, and garnish with fresh chopped parsley before serving.
