Slice the chicken breast into bite-sized pieces and season with half of the sea salt and black pepper.
Heat the olive oil in a large skillet over medium-high heat and sear the chicken until golden and cooked through, then remove and set aside.
In the same skillet, sauté the minced shallot, garlic, and sliced mushrooms until the mushrooms are browned and tender.
Add the arborio rice to the pan and toast for one minute, stirring constantly to coat the grains.
Lower the heat to medium and add the bone broth 0.25 cup at a time, stirring frequently until the liquid is absorbed before adding more.
With the final addition of broth, stir in the chopped asparagus and cook until the rice is tender and the asparagus is bright green.
Fold the cooked chicken, lemon juice, parmesan cheese, and the remaining salt and pepper into the risotto until the texture is creamy.
