Why You’ll Love This Recipe

We’ve been talking about comfort food, and this casserole delivers it in the best possible way. It’s creamy underneath, crisp on top, and filled with chicken and tender egg noodles.

Here are a few more reasons to love it:

• It’s wonderfully creamy. Cream of chicken soup, mayonnaise, milk, and cheddar cheese create the rich filling that coats the noodles.
• The topping is the best part. Panko breadcrumbs and melted butter become crisp and golden in the oven.
• It uses simple ingredients. Canned chicken, frozen vegetables, egg noodles, and a few pantry staples make up most of the casserole.
• It feeds the family. One 9×13-inch dish makes 6 satisfying servings.
• It’s easy to customize. Rotisserie chicken, another creamy soup, or a different breadcrumb topping can all work here.
• Leftovers are worth saving. Store them in the refrigerator and you have an easy meal ready for another day.

Chicken Noodle Casserole Ingredients

Here’s what each ingredient brings to this cozy casserole:

• Chicken – The hearty protein at the center of the casserole. Canned chunk chicken keeps things especially convenient, but the recipe also allows diced rotisserie chicken.
• Cream of Chicken Soup – This creates the creamy base of the casserole and helps bring the chicken, noodles, and vegetables together.
• Mayonnaise – Adds extra richness and gives the filling its smooth, creamy consistency.
• Milk – Loosens the creamy mixture so it coats the chicken and egg noodles evenly without becoming too thick.
• Onion – Adds a savory layer of flavor throughout the casserole. It’s optional, and dried onion flakes can be used when you don’t have a fresh onion on hand.
• Cheddar Cheese – Melts into the filling, giving the casserole plenty of cheesy flavor and an extra touch of richness.
• Frozen Peas and Carrots – An easy way to add vegetables, a little sweetness, and pops of color to every serving.
• Egg Noodles – Soft, tender egg noodles make up the comforting base of the dish and soak up all that creamy, cheesy filling.
• Panko Bread Crumbs – Sprinkled over the casserole to create a light, crisp topping that contrasts with the creamy noodles underneath.
• Salted Butter – Melted butter is poured over the panko before baking, helping the breadcrumbs turn crisp and beautifully golden in the oven.

Step-by-Step Instructions

Let’s make Chicken Noodle Casserole!

First, prepare your baking dish.

• Preheat oven to 350F degrees. Spray 9×13-inch baking dish with non-stick cooking spray.

Next, make the creamy filling.

• In a large bowl, combine 2 (12.5 ounce) cans chunk chicken breast, drained, 2 (10.5 ounce) cans cream of chicken soup, 1 cup mayonnaise, 1 cup milk, 1/2 onion, finely diced (optional), 2 cups shredded cheddar cheese and 1 1/2 cups frozen peas and carrots.
• At this point, you’ll have the creamy, cheesy base that brings the whole casserole together.

Add the noodles.

• Stir until combined. Gently stir in 12 ounce package egg noodles, cooked and drained.
• Be gentle here—you want to coat those noodles in the creamy filling without breaking them up too much.

Assemble the casserole.

• Pour mixture into prepared baking dish. Sprinkle top evenly with 1 cup panko bread crumbs.

Add the butter.

• Pour 1 stick salted butter (1/2 cup), melted evenly over top of bread crumbs.
• That combination of butter and panko is what gives the finished casserole its irresistible golden topping.

Finally, bake.

• Bake uncovered for about 30-35 minutes until bubbly and top is golden brown.
• Dig in and enjoy!

Expert Tips

This recipe is simple, but a few little details will help your casserole come out especially well.

Drain the chicken well. You want the creamy filling to come from the soup, mayonnaise, milk, and cheese—not extra liquid from the canned chicken.

Cook and drain the noodles before assembling the casserole. The egg noodles should be ready to go before you fold them into the filling.

Stir the noodles gently. Once the egg noodles go into the bowl, fold them into the mixture rather than stirring aggressively. This helps them stay intact.

Don’t thaw the vegetables unless you want them especially soft. The small frozen peas and carrots can cook right along with the casserole in the oven.

Give the breadcrumbs an even coating of butter. Pouring the melted butter across the entire surface helps the panko become golden and crisp instead of leaving dry patches.

Look for bubbling edges and a golden top. Those are your signs that it’s time to take the casserole out of the oven.

Want softer onions? Sauté them first. If you add them raw, they can still have a slight bite after baking.

Recipe Variations

One of the nice things about this Chicken Noodle Casserole is that there are several easy ways to adapt it using ingredients you already have.

Try a different chicken. The canned chicken keeps things convenient, but about 3 cups of diced store-bought rotisserie chicken works too. Leftover cooked or grilled chicken is another great option.

Switch the soup. No cream of chicken soup? Cream of mushroom or cream of celery can take its place.

Change up the topping. Panko gives the casserole a lovely crisp finish, but regular breadcrumbs or crushed Ritz crackers can also be used.

Use dried onion. If there’s no fresh onion in the kitchen, about 1 Tablespoon of dried onion flakes works instead.

These are simply options—the original ingredients and quantities can be followed exactly as written for the classic version.

Storage & Reheating

Have leftovers? You’re in luck. This is the sort of cozy casserole that makes an easy lunch or dinner the next day.

Transfer leftovers to an airtight container and refrigerate them for up to 3 days. Reheat individual portions until warmed all the way through.

If you’re reheating a larger amount in the oven, covering it for most of the reheating time can help keep the noodles from drying out. Uncover it toward the end if you’d like the breadcrumb topping to crisp back up.

You can freeze the casserole, too. Prepare it according to the recipe, but don’t bake it. Cover it very well and freeze for up to 3 months.

When you’re ready to bake, let the casserole partially defrost first. Because you’ll be starting with a colder casserole, plan on giving it about 10 extra minutes in the oven.

Serving Suggestions

This Chicken Noodle Casserole has chicken, vegetables, noodles, and cheese all tucked into one dish, so it can absolutely stand on its own for dinner. Still, I love pairing a rich, creamy casserole with something fresh and simple on the side.

A crisp green salad is an easy choice. You could also serve it with roasted broccoli, steamed green beans, asparagus, or another green vegetable. The freshness of the vegetables is a nice contrast to those creamy, cheesy noodles.

Want to lean all the way into comfort food? Add warm dinner rolls, biscuits, or garlic bread.

However you serve it, bring the casserole to the table while the filling is still bubbling and the buttery panko topping is crisp and golden. That first spoonful—with creamy noodles underneath and crunchy breadcrumbs on top—is the one you want.

Recipe FAQs

1. Can I use rotisserie chicken instead of canned chicken?

Yes! You can use about 3 cups of diced rotisserie chicken instead. Leftover cooked or grilled chicken works great here too, so this is a nice recipe for using up chicken you already have.

2. Do I need to cook the egg noodles first?

Yes, you’ll want to cook and drain the egg noodles before adding them to the casserole. Just be careful not to overcook them since they’ll continue to cook a little while the casserole is baking.

3. Do I need to thaw the frozen peas and carrots?

No, you can add the peas and carrots straight from the freezer. They’re small enough to cook right along with the casserole. If you like your vegetables extra soft, you can thaw them first.

4. What can I use instead of panko breadcrumbs?

Regular breadcrumbs work just fine! You can also use crushed Ritz crackers for a buttery, crunchy topping. Just spread them evenly over the casserole before adding the melted butter.

5. Can I make Chicken Noodle Casserole ahead of time?

Yes! You can assemble the casserole ahead of time and keep it covered in the refrigerator until you’re ready to bake. If baking it straight from the fridge, it may need a little extra time in the oven since the casserole will be cold.
