Make Chicken and Mushroom Soup: a cozy, easy bowl of shredded chicken, mushrooms, and rice in golden broth.
Melt the butter in a large soup pot over medium-high heat and add the diced onion, peeled diced carrots, celery, and sliced mushrooms. Cook, stirring occasionally, until the onion just begins to soften and the mushroom edges release moisture and start to brown slightly — about five minutes. Keep the vegetables visibly glossy from butter with clear edges and softened centers, a warm fragrant base for the soup.
Stir in the minced garlic, salt, dried parsley, thyme, poultry seasoning (or ground sage), and black pepper; cook just until the garlic becomes fragrant and the dried herbs bloom, coating the softened vegetables in a speckled, savory paste. This brief step deepens the aroma and tucks the flavors into the softened veg without overcooking the garlic.
Pour in the reduced-sodium chicken broth, nestle the two boneless skinless chicken breasts into the liquid, and add the uncooked long-grain white rice. Stir gently to distribute ingredients, then bring the pot to a lively boil so the rice begins to swell and the raw chicken is fully submerged and sealed by the golden broth.
Reduce heat to a steady medium-low simmer, cover, and cook for 20–25 minutes total, stirring once around the ten-minute mark so rice doesn’t cling. The broth should look clear and golden with rice expanding to pearly grains; the chicken will turn opaque and firm as it cooks through.

After about 15 minutes of simmering, lift the cooked chicken breasts from the pot and place them briefly on a plate to rest, then shred them into tender ribbons using two forks. The meat should be juicy and easily pull apart into irregular, rustic shreds.
Return the shredded chicken to the pot and stir until evenly distributed; once the rice is tender and the vegetables are soft but hold shape, ladle into a wide white serving bowl. Sprinkle a little extra dried parsley (or fresh chopped parsley if you prefer) over the surface for a bright, herb-flecked finish.
