Preheat oven to 350ºF (177ºC). Spray a 9x13 baking dish with nonstick cooking spray; set aside.
Drain thawed broccoli (20 ounces) in a colander then spread out on a double layer of paper towels to remove all excess moisture.
In a large mixing bowl, stir together the soup (2 cans), mayonnaise (1 cup), sour cream (1 cup), Cheddar (1 cup), lemon juice (1 tablespoon), curry powder (1 teaspoon), salt (1/4 teaspoon), pepper (1/2 teaspoon), to taste, wine (1/2 cup), and milk (1/2 cup) until combined.
Add the broccoli and chicken (6 cups) to the sauce and gently toss until evenly coated.
Pour mixture into prepared baking dish. Pat the top to even out with a rubber spatula.
In a small bowl mix together the topping ingredients. Sprinkle evenly over the casserole.
Bake the casserole in the preheated oven for 40-45 minutes or until the casserole is heated through the center.
Notes
Internal temperature: Since the meat is already cooked, you don’t really need to reach a particular temperature for food safety reasons. Aim for 165 degrees for thorough warming.
