In a small saucepan, bring the chicken bone broth to a gentle simmer and keep it warm over low heat.
Season the cubed chicken breast with a pinch of sea salt and black pepper.
Heat the olive oil in a wide skillet over medium-high heat and sear the chicken until golden and cooked through, then remove and set aside.
In the same skillet, add the minced shallot, garlic, and sliced mushrooms, sautéing until the mushrooms have released their moisture and turned brown.
Add the arborio rice to the skillet and toast for 2 minutes, stirring constantly until the edges are translucent.
Begin adding the warm broth one ladle at a time, stirring frequently and allowing the liquid to be fully absorbed before adding the next ladle.
When the rice is nearly tender, stir in the trimmed asparagus pieces and the cooked chicken.
Continue adding the remaining broth until the rice is al dente and the mixture is creamy.
Remove from heat and fold in the grated parmesan cheese, fresh thyme, and remaining sea salt and pepper before serving.
