Overnight Chicken Casserole: A Feast for Fifty

The aroma still lingers in my memory – a comforting blend of creamy soup, savory chicken, and the satisfying crunch of cornflakes. It takes me back to countless church suppers, school fundraisers, and family reunions where this very dish, or a close cousin of it, reigned supreme. There was always a joyful anticipation as the foil was peeled back, revealing the golden, bubbling surface, promising a hearty and delicious meal shared among friends and loved ones. Those shared experiences are the true essence of home cooking.

Recipe Overview

Prep Time: 45 minutes
Cook Time: 60-65 minutes
Total Time: Overnight + 1 hour 45 minutes
Servings: 45-50
Yield: 4 large casseroles
Dietary Type: Not Gluten-Free (can be adapted)

Ingredients

20 cups chicken, cooked and cubed
2 lbs macaroni, cooked and drained
36 ounces canned sliced mushrooms, drained
8 ounces diced pimentos, drained
2 large green peppers, chopped
2 large onions, chopped
4 (10 3/4 ounce) cans cream of celery soup
4 (10 3/4 ounce) cans cream of mushroom soup
2 lbs American cheese, cubed
1 1⁄3 cups milk
4 teaspoons dried basil
2 teaspoons lemon pepper seasoning
2 cups corn flakes, crushed
1⁄4 cup butter, melted

Equipment Needed

4 (9×13 inch) baking pans
Large mixing bowls
Measuring cups and spoons
Large spoon or spatula for mixing
Aluminum foil

Instructions

In a very large bowl (or split amongst several if necessary), combine the cooked chicken, cooked and drained macaroni, drained mushrooms, drained pimentos, chopped green peppers, and chopped onions. Ensure all ingredients are evenly distributed.
In a separate, equally large bowl, combine the cream of celery soup, cream of mushroom soup, cubed American cheese, milk, dried basil, and lemon pepper seasoning. Mix thoroughly until the cheese is mostly melted and the mixture is smooth.
Pour the soup and cheese mixture over the chicken and macaroni mixture. Stir gently but thoroughly to ensure all ingredients are well coated.
Divide the mixture evenly among four greased 9 x 13 inch baking pans. Each pan should receive approximately 12 cups of the casserole mixture.
Cover each pan tightly with plastic wrap or a lid if your pans have them, and refrigerate overnight. This allows the flavors to meld and the casserole to set. This step is crucial for the best flavor.
Remove the casseroles from the refrigerator 30 minutes before baking. This allows them to come to room temperature slightly, which will help them bake more evenly.
In a small bowl, combine the crushed corn flakes and melted butter. Mix well until the corn flakes are evenly coated.
Sprinkle the buttered corn flakes evenly over the top of each casserole.
Cover each casserole dish tightly with aluminum foil.
Bake in a preheated oven at 350 degrees Fahrenheit for 45 minutes. Covering with foil prevents the cornflakes from burning and helps the casserole heat through evenly.
Remove the foil and bake for an additional 15 to 20 minutes, or until the casserole is bubbly and the cornflake topping is golden brown. The exact baking time may vary depending on your oven.
Let stand for 10 minutes before serving to allow the casserole to set slightly.

Expert Tips & Tricks

Cheese Considerations: While the recipe calls for American cheese, you can substitute with shredded cheddar, Colby Jack, or a blend of your favorite cheeses. Pre-shredded cheese melts more quickly and evenly.
Soup Alternatives: If you don’t have cream of celery or cream of mushroom soup on hand, cream of chicken or cream of cheddar soup can be used as substitutes. You can even use a combination to create a unique flavor profile.
Make-Ahead Magic: This casserole is an excellent make-ahead dish. You can assemble it up to 2 days in advance and store it in the refrigerator. Just add the cornflake topping before baking.
Preventing Dryness: To prevent the casserole from drying out, ensure it is well covered with foil during the initial baking period. If you notice the topping is browning too quickly, you can loosely tent the foil over the casserole.
Chicken Tip: Rotisserie chicken is a great shortcut for the cooked chicken! It adds a ton of flavor, and saves time. Just shred or cube the chicken and it’s ready to use.
Macaroni Math: Ensure you cook the macaroni al dente; it will continue to cook in the casserole. Overcooked macaroni will result in a mushy texture.

Serving & Storage Suggestions

Serve the Overnight Chicken Casserole hot, directly from the baking dish. Garnish with a sprinkle of fresh parsley or a dash of paprika for added visual appeal. This casserole pairs well with a simple green salad, steamed vegetables, or a side of garlic bread.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions or bake the entire casserole covered with foil in a preheated oven at 350 degrees Fahrenheit until heated through.

For longer storage, the casserole can be frozen. Allow the casserole to cool completely before wrapping it tightly in plastic wrap and then aluminum foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Variations & Substitutions

Gluten-Free: Substitute gluten-free macaroni and crush gluten-free cornflakes or use crushed gluten-free crackers for the topping.
Dairy-Free: Use dairy-free cream soups, dairy-free cheese (such as a cashew-based cheese), and dairy-free milk alternative (almond, soy, or oat milk) to make a dairy-free version. The flavor will be slightly different, but still delicious.
Vegetarian Option: Replace the chicken with a can (or more, to taste) of drained and rinsed white beans or chickpeas for a vegetarian option. You could also add extra chopped vegetables like carrots, celery, or zucchini.
Spicy Kick: Add a pinch of cayenne pepper or a dash of hot sauce to the soup mixture for a spicy kick.
Herb Infusion: Experiment with different herbs such as thyme, rosemary, or oregano to add unique flavor notes to the casserole.

FAQs (Frequently Asked Questions)

Q: Can I use pre-cooked chicken from the grocery store?
A: Absolutely! Rotisserie chicken or pre-cooked chicken strips are a great time-saver. Just make sure to shred or cube the chicken before adding it to the casserole.

Q: Can I assemble this casserole in advance and freeze it?
A: Yes, you can assemble the casserole (without the cornflake topping) and freeze it for up to 2 months. Thaw it overnight in the refrigerator before baking, and then add the cornflake topping.

Q: What if I don’t have American cheese?
A: You can substitute with shredded cheddar, Colby Jack, or a blend of your favorite cheeses. Just ensure the cheese melts well.

Q: How do I prevent the cornflake topping from burning?
A: To prevent burning, cover the casserole with foil during the initial baking period and remove it only during the last 15-20 minutes to allow the topping to brown.

Q: Can I use fresh mushrooms instead of canned?
A: Yes, you can use fresh mushrooms. Sauté them with the onions and green peppers until softened before adding them to the casserole.
