Chicken and Rice Casserole with Mushrooms and Spinach is a creamy, wholesome one-pan meal featuring tender chicken, earthy mushrooms, and fresh spinach baked with rice in a comforting, cheesy sauce. It’s a nourishing, crowd-pleasing dish perfect for weeknight dinners or meal prep.

Ingredients

  • 4 boneless, skinless chicken breasts or thighs
  • 1 cup long-grain white rice (uncooked)
  • 2 1/4 cups chicken broth
  • 8 oz fresh mushrooms (button, cremini, or baby bella), sliced
  • 4 cups fresh spinach
  • 1 small onion, chopped
  • 3 cloves garlic, minced
  • 1 tbsp olive oil or butter
  • 4 oz cream cheese or 1/2 cup sour cream
  • 1 cup shredded mozzarella or Swiss cheese
  • 1/2 tsp dried thyme or Italian seasoning
  • Salt, to taste
  • Black pepper, to taste
  • 1/4 cup grated Parmesan cheese (optional, for topping)

Instructions

  1. Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
  2. In a skillet, heat olive oil or butter over medium heat. Sauté onion and garlic until softened, about 2–3 minutes. Add mushrooms and cook until browned. Stir in spinach and cook until wilted. Remove from heat and set aside.
  3. In a large bowl, mix chicken broth, cream cheese or sour cream, dried herbs, uncooked rice, salt, and pepper until combined.
  4. Spread the rice mixture evenly into the prepared baking dish. Stir in the sautéed mushrooms and spinach mixture.
  5. Season chicken with salt and pepper and place on top of the rice mixture.
  6. Cover tightly with foil and bake for 45 minutes.
  7. Remove foil, sprinkle mozzarella cheese on top, and bake uncovered for 15–20 minutes until the chicken is cooked through and rice is tender.
  8. Let rest for 5 minutes before serving. Sprinkle with Parmesan cheese if desired.

Notes

  • Use cooked chicken to reduce baking time by about 15 minutes.
  • Substitute cream cheese with cream of mushroom soup for a shortcut.
  • Frozen spinach can be used—just thaw and drain well before adding.
  • Add extra vegetables like bell peppers, zucchini, or shredded carrots for more nutrition.
  • Brown rice can be used, but increase broth to 2 3/4 cups and extend bake time by 15–20 minutes.
