How to Make Chicken Noodle Casserole Recipe
Step 1: Preheat and Prep
Start by preheating your oven to 400°F (200°C) and giving a 13×9-inch baking pan a light grease so your casserole slides out easily after baking. This step sets the stage for everything to come, so don’t skip it.
Step 2: Cook the Noodles
Bring salted water to a boil and cook the extra-wide egg noodles until nearly al dente—this ensures they won’t get mushy during baking. Drain and immediately rinse with cold water to stop cooking, then toss with 1 tablespoon of butter to keep them rich and prevent sticking.
Step 3: Sauté the Mushrooms
In a skillet over medium-high heat, warm 1 tablespoon of olive oil and 1 tablespoon of butter. Sauté the sliced mushrooms until they are beautifully browned and have released their delicious juices. Once done, transfer them into the pot with your noodles for easy mixing later.
Step 4: Cook the Carrots and Onions
Using the same skillet, melt another tablespoon of butter, then add the chopped carrots and onions. Sauté until tender and fragrant, adding a lovely sweetness and softness to the texture. Combine them with the noodles and mushrooms to keep everything together.
Step 5: Make the Cheese Sauce
In the skillet, melt 3 tablespoons of butter and whisk in the flour, cooking it for about a minute to eliminate the raw taste. Gradually whisk in the whole milk and chicken broth, bringing the mixture to a boil before reducing the heat to simmer until thickened to a creamy sauce. Stir in the chopped American cheese and shredded sharp cheddar until melted and smooth, then add garlic powder, Dijon mustard, and season with salt and pepper to taste. This sauce is the luscious glue that brings the casserole to life.
Step 6: Combine, Assemble, and Top
Pour the cheese sauce over the noodles, mushrooms, and vegetables, folding gently to coat everything evenly. Add the diced chicken and frozen peas, folding carefully to distribute. Transfer the full mixture to the prepared baking pan. Melt the remaining butter and drizzle this over the broken Ritz crackers, then sprinkle these buttery crumbs on top to create a golden, crunchy topping.
Step 7: Bake to Perfection
Bake the casserole for about 15 minutes until it’s bubbly and the topping is golden brown. To avoid over-browning, place a tent of foil over the casserole halfway through baking. Once out of the oven, allow it to cool for 10 minutes—it helps the casserole set and makes serving easier.

Garnishes

Make Ahead and Storage
Storing Leftovers
Store any leftover Chicken Noodle Casserole Recipe in an airtight container in the refrigerator for up to 3 days. This way, you can reheat it easily for a quick and comforting meal without losing any of its creamy goodness.
Freezing
This casserole freezes wonderfully. Prepare and assemble it as instructed, then cover tightly with foil and freeze for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator before baking as usual.
Reheating
Reheat individual portions in the microwave or warm the entire casserole in a 350°F oven until heated through and bubbly again. Adding a splash of milk or broth before reheating helps maintain the sauce’s creamy texture.
FAQs
Can I use different types of noodles for this casserole?
Absolutely! While extra-wide egg noodles work best because they hold the sauce and texture well, you can substitute with other pasta shapes like penne or rotini. Just keep in mind cooking times may vary slightly.
Is it possible to make this casserole vegetarian?
Yes, simply omit the chicken and increase the vegetables, or add plant-based proteins like tofu or chickpeas. Using vegetable broth instead of chicken broth will keep it fully vegetarian while maintaining rich flavor.
Can I prepare this casserole ahead of time?
Definitely. You can assemble the whole casserole a day before and keep it covered in the fridge. When ready, bake it fresh to enjoy that golden topping and warm, cheesy comfort.
What cheese alternatives can I use?
You can swap the American and cheddar cheese with other melty cheeses like Monterey Jack, mozzarella, or Gruyère for different flavor profiles, but the combination of mild and sharp cheeses here is perfect for balance.
How do I avoid the topping from burning?
To prevent the buttery cracker topping from burning, tent the casserole with foil halfway through baking. This protects the crust while still allowing it to get crisp and golden.
