- Melted Butter – Binds the topping and helps it bake up golden and crisp.

Instructions
Here’s how to make this delicious chicken casserole. You can find the full ingredients list along with instructions in the recipe card below.
Preheat the oven to 350°
First, in a 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.
PRO TIP: Be sure to shred the mozzarella yourself and avoid the pre shredded stuff that comes in a bag. It will melt much better that way.

Then, in a separate bowl, combine the crushed Ritz crackers and melted butter until fully coated. Sprinkle the buttery cracker mixture evenly over the casserole.
PRO TIP: Don't crush the crackers up too finely and leave it a little chunky. It will brown up and create a really nice texture that way.

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!
PRO TIP: Let the casserole sit to settle and firm up. That way it wont be too runny when its being served.

Can I Make This Ahead Of Time?
Yes, this can be made ahead of time. Just assemble the casserole it up to 24 hours in advance, cover, refrigerate, and bake when ready.
What Kind Of Cheese Can I Use?
Cheddar, Colby Jack, or Monterey jack all work great. Feel free to use what you have.
Storage
Let the casserole cool completely and place it into an air tight container. It will last in the refrigerator for up to three days.
