Season the chicken breasts with salt, pepper, and dried thyme.
Heat olive oil in a large skillet over medium-high heat. Add the chicken and cook for 5-7 minutes per side until golden brown and cooked through. Remove chicken from the skillet and set aside.
In the same skillet, add the garlic and cook for 1 minute until fragrant. Add the sliced mushrooms and cook for about 5 minutes, stirring occasionally.
Pour in the chicken broth and scrape any browned bits from the bottom of the skillet. Let the broth simmer for 3 minutes, allowing the flavors to combine.
Return the chicken to the skillet, spooning the mushroom mixture over the top. Cover and simmer for another 5 minutes to reheat the chicken.
Garnish with fresh parsley before serving.
Notes
For an extra creamy version, add a splash of cream or a dollop of sour cream at the end of cooking. Pair with steamed vegetables or quinoa for a complete meal.
