• 1 dash hot pepper sauce
• 10 3/4 ounces condensed cream of chicken soup

• 2 eggs, separated
• 1 cup flour
• 1 1/2 teaspoons baking powder
• 3/4 cup milk
• 1/4 cup melted butter
• Paprika for sprinkling

Equipment Needed

• 2-quart casserole dish
• Large bowl
• Small bowl
• Mixer (hand or stand)
• Whisk
• Measuring cups and spoons

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 2-quart casserole dish. This helps prevent sticking and ensures easy cleanup.

2. In a large bowl, prepare the creamy spinach base. Combine 1 cup of sour cream, 1/3 cup of milk, 1/4 cup of chopped onion, 1/2 teaspoon of garlic salt, 1/4 teaspoon of cumin, and a dash of hot pepper sauce. Blend these ingredients well for an even flavor distribution.

3. Add the remaining vegetables and soup to the creamy base. Incorporate the 10 3/4 ounces of condensed cream of chicken soup, the 9 ounces of thawed and drained frozen chopped spinach, the 4 ounces of drained chopped green chilies, and the 2 ounces of drained chopped pimiento. Mix thoroughly until everything is well combined. Be sure the spinach is thoroughly drained, or your casserole could be watery.

4. In a separate bowl, combine the cubed cooked chicken and the shredded cheeses. Gently toss 3 cups of cubed cooked chicken, 4 ounces of shredded Monterey Jack cheese, and 2 ounces of shredded cheddar cheese together. This ensures the chicken and cheese are evenly distributed throughout the casserole.

5. Layer the casserole. Begin by spooning half of the spinach mixture into the prepared casserole dish. Sprinkle half of the chicken mixture over the spinach layer. Repeat these layers, using the remaining spinach mixture and chicken mixture, ensuring an even distribution.

6. Prepare the topping. First, separate the eggs. In a clean bowl, beat the egg whites until they form soft peaks. This step is crucial for a light and airy topping. Set the beaten egg whites aside.

7. In another bowl, combine the dry and wet ingredients for the topping base. Mix together 1 cup of flour, 1 1/2 teaspoons of baking powder, 3/4 cup of milk, 1/4 cup of melted butter, and the egg yolks from the separated eggs. Beat at low speed until just moistened, then increase the speed to high and beat for 4 minutes. This develops the gluten in the flour and creates a smooth batter.

8. Gently fold the egg whites into the batter. Using a spatula, carefully fold the beaten egg whites into the batter until just combined. Be gentle to avoid deflating the whites, which will ensure a light and fluffy topping.

9. Pour the topping over the casserole. Pour the topping evenly over the chicken and spinach layers in the casserole dish.

10. Sprinkle with paprika. Sprinkle paprika generously over the top of the casserole. This adds a touch of color and a subtle smoky flavor.

11. Bake the casserole. Bake in the preheated oven for 40 to 45 minutes, or until the topping is golden brown and the casserole is bubbly. A toothpick inserted into the center should come out clean.

Expert Tips & Tricks

• Make-Ahead Magic: Prepare the casserole a day in advance, up to the point of adding the topping. Cover and refrigerate. Add the topping just before baking. You may need to add 10-15 minutes to the baking time if baking from cold.
• Spice It Up: Adjust the amount of hot pepper sauce to your liking. A pinch of cayenne pepper to the chicken mixture also adds a nice kick.
• Cheese Please: Feel free to experiment with different cheeses. Pepper jack cheese adds a bit of heat, while a blend of cheddar and mozzarella offers a classic flavor.
• Draining is Key: Ensure the spinach and green chilies are thoroughly drained. Excess moisture will result in a soggy casserole. Press the spinach between paper towels to remove as much water as possible.
• Check for Doneness: The casserole is done when the topping is golden brown and a toothpick inserted into the center comes out clean. If the topping is browning too quickly, tent the casserole with foil.

Serving & Storage Suggestions

Serve the Fiesta Chicken Casserole warm, straight from the oven. It pairs well with a simple side salad or a scoop of sour cream or guacamole.

• Room Temperature: Do not leave the casserole at room temperature for more than 2 hours.
• Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Freezing: For longer storage, freeze the casserole in individual portions or in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
• Reheating: Reheat in the oven at 350°F (175°C) until heated through, or microwave individual portions.
