Poppy seed chicken casserole is the ultimate easy comfort food made with rotisserie chicken, a rich cheese sauce, and a buttery cracker topping that everyone goes back for.
In a medium sized bowl, mix together the cream of chicken soup, sour cream, shredded mozzarella, poppy seeds, salt, and pepper until smooth. Stir in the shredded chicken and cheese. Spread the mixture to the bottom of a greased 9 x 13" baking dish.
In a separate bowl, combine the crushed Ritz Crackers and melted butter until fully coated. Sprinkle the buttery cracker mixture evenly over the casserole.
Next, place it into the center rack of the oven uncovered for 30–35 minutes, or until hot, bubbly, and golden on top. Let rest for 5–10 minutes. Garnish with parsley (optional) and enjoy!
