  • 4 cups rotisserie chicken, chopped
  • 12 – 16 oz package of frozen vegetables
  • 2 (10.5 oz) cans of cream of soup (celery, mushroom, or chicken)
  • 1/2 cup of milk
  • 8 oz sour cream
  • 1/4 tsp salt
  • 1/4 tsp ground black pepper
  • 1/4 tsp garlic powder
  • 1/4 tsp onion powder
  • 1/4 tsp smoked paprika
  • 1 sleeve of Ritz crackers, crushed
  • 4 tbsp melted butter
  • 1 cup shredded cheddar cheese
  • sliced green onions, for garnish


Step 1

Preheat your oven to 350 degrees F and grease your casserole dish with a nonstick cooking spray. Set it aside. Chop your rotisserie chicken into bite-size pieces, transfer it to the prepared casserole dish, then layer the frozen vegetables (of your choice) on top of the chicken. Set aside. Next, add two cans of cream of soup (of your choice) in a large mixing bowl along with 1/2 cup of milk, 8 oz of sour cream, 1/4 tsp salt, 1/4 tsp ground black pepper, 1/4 tsp garlic powder, 1/4 tsp onion powder, and 1/4 tsp smoked paprika. Whisk everything together to combine.

Step 2

Pour it over the vegetables, spreading it nicely and evenly. Crush one sleeve of Ritz crackers and add 4 tbsp melted butter, then sprinkle it over the top of the casserole together with 1 cup shredded cheddar cheese. Place it in the preheated oven and bake for 40 minutes until all the cheese melts. Serve and enjoy!
