Season the chicken breast with half of the sea salt and black pepper.
Heat the olive oil in a non-stick skillet over medium-high heat and sear the chicken until golden and cooked through, then remove from the pan and let it rest.
In the same skillet, add the minced shallots, garlic, and sliced mushrooms, sautéing until the mushrooms are tender and browned.
Add the arborio rice to the skillet and toast for one minute while stirring constantly until the edges appear translucent.
Begin adding the chicken bone broth 0.25 cup at a time, stirring frequently and allowing the liquid to be fully absorbed before adding the next portion.
Continue the process until the rice is tender and has created a natural, creamy sauce.
Fold in the parmesan cheese, fresh thyme, and the remaining salt and pepper.
Slice the rested chicken breast and serve it immediately over the warm risotto.
