Savory Garlic Mushroom Chicken with Spinach

In the same skillet, add the butter and let it melt. Add the sliced mushrooms and cook for 5-6 minutes, stirring occasionally, until the mushrooms are softened and browned.
Add the minced garlic and cook for 1 minute until fragrant.
Make the Sauce:

Pour in the chicken broth, scraping up any bits from the bottom of the skillet. Stir in the dried thyme and bring the mixture to a simmer. Let it cook for 3-4 minutes, reducing the liquid slightly.
Stir in the heavy cream and allow the sauce to simmer for another 2-3 minutes, until it thickens.
Wilt the Spinach:

Add the fresh spinach to the skillet and stir it into the sauce. Cook for 2-3 minutes until the spinach wilts down and incorporates into the sauce.
Finish the Dish:

Return the cooked chicken breasts to the skillet, spooning some of the sauce and mushrooms over the top. Cook for another 2-3 minutes to reheat the chicken and let the flavors combine.
