How to Make Cheesy Chicken and Spinach Casserole with Mushrooms
Prep Your Oven and Dish: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish with cooking spray to prevent sticking.
Cook the Chicken: In a skillet over medium heat, cook diced chicken until golden brown, about 7-10 minutes. You want it cooked thoroughly but still juicy.
Sauté the Veggies: Add chopped mushrooms and spinach to the skillet with the chicken. Cook until mushrooms are tender and spinach wilts down nicely, about 5 minutes.
Create the Creamy Mixture: In a large bowl, combine cooked chicken mixture with softened cream cheese, garlic powder, onion powder, salt, and pepper. Stir until well blended.
Add to Baking Dish: Transfer the creamy chicken mixture into your prepared baking dish evenly spreading it out so every bite gets love.
Topping Time!: Sprinkle shredded cheese evenly over the top followed by panko breadcrumbs for that irresistible crunch. Bake in preheated oven for 30-35 minutes until bubbly and golden brown.
