In a medium saucepan, bring the chicken bone broth to a gentle simmer over low heat and keep it warm.
Heat the extra virgin olive oil in a large skillet over medium heat; add the diced chicken breast and sliced cremini mushrooms, sautéing until the chicken is cooked through and mushrooms are golden brown.
Remove the chicken and mushrooms from the skillet and set them aside on a plate.
In the same skillet, add the minced shallot and garlic, cooking for about 1 minute until fragrant and translucent.
Add the Arborio rice to the skillet, stirring for 2 minutes to lightly toast the grains until the edges become slightly translucent.
Begin adding the warm bone broth one ladle at a time, stirring frequently and allowing the liquid to be almost fully absorbed before adding the next ladle.
Continue this process for approximately 18 to 20 minutes until the rice is tender and the consistency is creamy.
Stir the cooked chicken, sautéed mushrooms, sea salt, black pepper, and fresh thyme back into the risotto skillet.
Remove the skillet from the heat and fold in the grated parmesan cheese until melted and incorporated.
Serve immediately while the risotto is warm and velvety.
