Season chicken breasts with salt, pepper, and any other preferred seasonings.
Sear the chicken in a large skillet over medium-high heat, cooking each side for about 2-3 minutes until golden brown.
Remove the chicken from the skillet and set aside.
Add mushrooms, onion, thyme, garlic, and chicken broth to the pan. Bring the mixture to a boil.
Return the chicken to the skillet and cover, letting it simmer for about 5-10 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Roast the asparagus: While the chicken is cooking, preheat your oven to 375°F (190°C). Toss asparagus with olive oil, salt, and pepper, then roast for 12-15 minutes until tender.
Serve the chicken and mushroom mixture with the roasted asparagus.
