Ingredients You’ll Need

Before we get started, let’s talk ingredients. This casserole is all about rich, creamy textures and bold flavors, and every ingredient plays its part.

For the Casserole Base:

• 3 cups cooked chicken, shredded (Rotisserie chicken works great!)
• 1 (10.5 oz) can cream of chicken soup
• 1 (10.5 oz) can cream of mushroom soup
• 1 cup sour cream
• 1 cup mayonnaise
• 1 tsp garlic powder
• 1 tsp onion powder
• Salt and pepper, to taste
• 2 cups egg noodles, cooked and drained
• 1 (14.5 oz) can diced tomatoes, drained (optional)
• 1 cup shredded cheddar cheese

For the Crunchy Topping:

• 1 cup crushed cornflakes
• 2 tbsp butter, melted

How to Make Cheesy Chicken Casserole

Let’s get cooking! This recipe is as simple as mix, layer, bake, but I’ll walk you through each step with tips to make it even easier.

Step 1: Preheat Your Oven

Set your oven to 350°F (175°C). Preheating ensures that your casserole bakes evenly, giving you that perfect golden-brown top.

Step 2: Make the Creamy Base

In a large mixing bowl, combine:

• Shredded chicken
• Cream of chicken soup
• Cream of mushroom soup
• Sour cream
• Mayonnaise
• Garlic powder & onion powder
• A little salt & pepper

Give everything a good stir until it’s smooth and creamy. This is what makes the casserole rich, moist, and totally irresistible!

 Pro Tip: If you want a little extra tang, you can substitute Greek yogurt for some of the sour cream.

Step 3: Add the Noodles & Tomatoes

Gently fold in your cooked egg noodles and diced tomatoes (if using). Be careful not to overmix—you want the noodles to stay whole, not break apart.

 Variation Idea: Not a fan of egg noodles? Swap them out for cooked rice or penne pasta for a slightly different texture.

Step 4: Transfer to the Baking Dish

Grease a 9×13-inch baking dish and spread the mixture evenly inside. This ensures your casserole doesn’t stick and makes cleaning up a breeze.

Step 5: Cheese It Up!

Sprinkle 1 cup of shredded cheddar cheese evenly over the top of the casserole. This creates that ooey-gooey, cheesy layer that makes every bite pure bliss.

 Cheese Lovers’ Tip:
Want to mix it up? Try using a blend of cheeses like mozzarella, Monterey Jack, or even Pepper Jack for a little kick!

Step 6: Make the Buttery Crunch Topping

No casserole is complete without a little crunch, and this one gets its golden topping from buttery crushed cornflakes. Here’s how to make it:

How to Make the Perfect Crunchy Topping:

•  In a small bowl, mix 1 cup of crushed cornflakes with 2 tablespoons of melted butter.
• Stir until all the cornflakes are coated in buttery goodness.
•  Evenly sprinkle the mixture over the cheese layer.

 Pro Tip:
No cornflakes? No problem! Try using crushed Ritz crackers, Panko breadcrumbs, or even French fried onions for a different kind of crunch.

Step 7: Bake to Golden Perfection

Place the baking dish into your preheated oven (350°F/175°C) and bake for 30-35 minutes. Here’s what to look for:

• The cheese should be melted and bubbly
• The topping should be golden brown and crispy

 Want an extra-crispy topping?
For the last 5 minutes of baking, switch your oven to BROIL and let the top get extra golden and crunchy—just keep an eye on it so it doesn’t burn!

Step 8: Let It Rest & Serve

Once your casserole is out of the oven, let it sit for about 5 minutes before digging in. I know, I know—it’s hard to wait! But this step helps the casserole set, making it easier to serve.

Now, grab a big spoon and scoop up that creamy, cheesy, crispy goodness!

FAQ: Your Casserole Questions Answered!

Here are the most common questions people have about this cheesy, delicious casserole:

1️⃣ Can I Make This Casserole Ahead of Time?

Absolutely! This casserole is a great make-ahead meal. Simply assemble everything up to the baking step, cover it with foil, and store it in the fridge for up to 24 hours before baking. When you’re ready to cook, just pop it in the oven and bake as directed.

 Pro Tip: If baking straight from the fridge, add an extra 5-10 minutes to the cook time to ensure it heats through.

2️⃣ Can I Freeze This Casserole?

Yes! This is a great freezer meal. Here’s how to do it:

• Before Baking: Assemble everything, wrap it tightly in plastic wrap, then cover with foil. Freeze for up to 3 months. When ready to bake, thaw overnight in the fridge, then bake as directed.
• After Baking: Let the casserole cool completely, then store in an airtight container or wrap individual portions in plastic wrap. Freeze for up to 3 months. Reheat in the oven at 350°F for 20 minutes, or microwave individual servings.

3️⃣ What Can I Use Instead of Mayonnaise?

Not a fan of mayo? No problem! Here are some great substitutes:

• Greek Yogurt – A healthier swap that adds a tangy flavor.
• More Sour Cream – Keeps it creamy and delicious.
• Cream Cheese – For an even richer texture (soften before mixing).
• Heavy Cream – Adds creaminess without altering the flavor too much.

4️⃣ Can I Use Different Types of Cheese?

Definitely! While cheddar is a classic, here are some fun cheese swaps to try:

• Mozzarella – Melts beautifully and adds a gooey texture.
• Colby Jack – A mild, creamy cheese that blends well.
• Parmesan – Adds a salty, nutty bite to the topping.
• Pepper Jack – For a little spicy kick!

5️⃣ How Do I Keep the Topping from Getting Soggy?

If you want to keep the crispy topping crunchy, here’s what to do:

• Don’t add the topping until just before baking. If making ahead, store it separately and sprinkle on just before putting it in the oven.
• Broil for the last 2-3 minutes to get extra crispiness.
• Let it rest for 5 minutes before serving. This helps the moisture redistribute so the top stays crisp!

6️⃣ Can I Make This Recipe Without Noodles?

Yes! If you’re looking for a low-carb version, try these alternatives:

• Cauliflower Rice – A great swap that still absorbs all the flavors.
• Zucchini Slices – Layer thin slices for a casserole-style dish.
• Chopped Broccoli – Adds extra nutrition while keeping the creamy texture.
• Quinoa or Brown Rice – For a heartier, protein-packed alternative.

7️⃣ Can I Make This in a Slow Cooker?

Yes! If you want a Crockpot version, follow these steps:

1. Mix everything together except the cheese and topping.
2. Cook on LOW for 4-5 hours or HIGH for 2-3 hours.
3. Sprinkle cheese on top in the last 30 minutes so it melts.
4. Just before serving, add the topping and broil for 3-5 minutes in the oven for crispiness.
