How to Make Million Dollar Chicken Casserole
Let’s walk through creating this Million Dollar Chicken Casserole. Each step is designed to help you succeed in making a delicious and satisfying meal.
1. Preheat oven to 350ºF (175°C). Sauté finely chopped leeks in a little butter until softened, filling your kitchen with a sweet aroma. Add dried thyme for that earthy touch. Lightly spray a 9×9-inch baking dish with cooking spray and set aside. To learn more about the different types of cooking spray, you can visit this article.
2. In a large bowl, combine chicken, softened cream cheese (ensure it’s softened for easy mixing), cottage cheese, sour cream, cream of chicken soup, garlic powder, and onion powder. Gently fold in the sautéed leeks and thyme, distributing the flavor evenly. Spread the mixture evenly into the prepared baking dish.
3. In a separate bowl, combine crushed Ritz crackers and melted butter. Mix until the crackers are evenly coated, creating a crumble that will turn golden brown in the oven. Sprinkle the buttery cracker mixture evenly over the chicken mixture.
4. Bake uncovered for 30 to 40 minutes, or until the casserole is golden brown and bubbly. The aroma will be irresistible! Check that the internal temperature reaches 165°F (74°C) for food safety, ensuring it’s heated through. You can use a food thermometer to ensure proper temperature.
Freezing and Reheating Instructions
You can freeze this Million Dollar Chicken Casserole either before or after baking. To freeze before baking, assemble the casserole as instructed, but don’t bake it. Wrap it tightly in plastic wrap and then in foil. It can be stored in the freezer for up to 2-3 months.
To freeze after baking, let the casserole cool completely. Wrap it tightly in plastic wrap and then in foil.
For thawing, place the frozen casserole in the refrigerator overnight. Bake the thawed casserole at 350°F (175°C) for 20-30 minutes, or until heated through.
Detailed guidance on thawing and reheating frozen casserole: If the cracker topping starts to brown too quickly, cover the casserole with foil. For the best texture, I recommend broiling the casserole for the last few minutes to crisp up the topping, being careful not to burn it.
Preventing a Soggy Cracker Topping
A soggy cracker topping can ruin a perfectly good casserole. Here are a few tricks to prevent it:
Broil: For the last few minutes of baking (or after reheating), broil the casserole to crisp up the topping. Watch it carefully to prevent burning.
Toast the Crackers: Toast the crushed crackers with the melted butter in a skillet before sprinkling them over the chicken mixture. This will help them stay crispier.
Reduce Soup: Use a little less cream of chicken soup. The excess moisture can lead to a soggy topping.
