Heat the olive oil in a large skillet over medium-high heat.
Add the diced chicken breast and sauté until golden brown and cooked through, then remove from the pan and set aside.
In the same skillet, add the minced shallot, garlic, and sliced mushrooms, cooking until the mushrooms release their moisture and turn tender.
Stir in the arborio rice, toasting the grains for about one minute until the edges become translucent.
Reduce heat to medium and add the bone broth 1/4 cup at a time, stirring frequently and waiting for the liquid to be fully absorbed before adding more.
Once the rice is tender and creamy, stir the cooked chicken and parmesan cheese back into the skillet until well combined.
Season with sea salt and black pepper, then garnish with chopped fresh parsley before serving.
