Method
- Heat the olive oil or butter in a large pot or Dutch oven over medium heat. Add the diced onion and celery and cook until they are soft and translucent, about $5text{ minutes}$.
- Add the sliced mushrooms to the pot and cook until they turn golden brown, approximately $10text{ minutes}$. Sautéing them well is essential for developing a deep, rich umami flavor.
- Stir in the fresh thyme and crushed garlic, cooking until fragrant, about $1text{ minute}$.
- Pour in the $6text{ cups}$ of stock and the $1text{ cup}$ of cream. Bring the mixture to a gentle simmer.
- Cook the base for $5text{ minutes}$, then add the shredded rotisserie chicken and chopped spinach. Simmer for an additional $5text{ minutes}$ until the spinach wilts completely.
- Season the soup generously with salt, pepper, and a pinch of chili flakes. Adjust flavors as needed (a squeeze of lemon juice can brighten the overall taste). Serve hot.
Notes
For the deepest flavor, ensure the mushrooms are cooked until they develop a golden-brown crust. If you plan to freeze, do not add the cream before freezing; add it after the soup has thawed and is being reheated. For a thicker soup, mix $1text{ tbsp}$ cornstarch with $2text{ tbsp}$ cold water (a slurry) and stir it into the simmering stock before adding the cream.
