Spray the bottom of a crock pot with non-stick cooking spray. Place 2 pounds boneless skinless chicken breasts inside the crock pot.
In a medium bowl, whisk together 1 (8-ounce) container sour cream, 1 (10.5-ounce) can cream of chicken soup, and ½ cup shredded parmesan cheese.
Pour the sour cream mixture over the chicken in the crock pot.
Place the lid on the crockpot and cook on LOW for 5-6 hours, or HIGH for 3-4 hours.
Remove the lid and shred the chicken with two forks. Stir in 2 teaspoons poppy seeds.
In a large skillet, add ½ cup butter and melt over medium heat. Once the butter is melted, add 1 sleeve crushed Ritz Crackers and toss to coat in the butter. Toast the cracker mixture for 2-3 minutes until golden brown.
Sprinkle the cracker mixture on top of the chicken mixture. Season with salt and pepper, if needed, and serve over potatoes or rice!
