How to Make Creamy Chicken Noodle Casserole Recipe
Step 1: Get Oven and Noodles Ready
Begin by preheating your oven to 350°F (175°C) so it’s perfectly hot when your casserole is ready to bake. Cook the extra-wide egg noodles according to the package, ensuring they’re just tender but not mushy. Drain well and season lightly with salt and pepper, then set them aside to await their cheesy destiny.
Step 2: Sauté the Vegetables
In a large skillet, warm olive oil together with half the butter over medium heat. Toss in the mushrooms, carrots, and onion, sautéing until tender and fragrant — about 7 to 8 minutes. This creates a flavorful, aromatic foundation packed with texture and color that will spread throughout your casserole.
Step 3: Build the Creamy Sauce
Sprinkle the flour over the cooked vegetables and stir constantly for a couple of minutes to cook out the raw taste and form a roux. Gradually whisk in the whole milk and chicken broth, allowing the mixture to thicken and bubble gently for five minutes. This luscious sauce is the heart of your casserole, so stir patiently to develop that creamy magic.
Step 4: Add Cheese and Seasoning
Once your sauce is thick and creamy, fold in the chopped American cheese and shredded sharp cheddar. Stir until everything melts into a velvety smooth sauce with a perfect balance of mild and tangy notes. Then season with garlic powder and Dijon mustard for an exciting depth that ties every ingredient together beautifully.
Step 5: Combine Chicken and Peas
Toss in your cooked chicken and frozen peas, stirring just enough to marry them into the cheesy sauce without breaking the peas’ fresh snap. This combination turns the sauce into a hearty, protein-rich filling that feels indulgent but wholesome.
Step 6: Mix in Egg Noodles and Prepare to Bake
Gently fold the cooked egg noodles into the sauce until every strand is enveloped in creamy deliciousness. Pour the entire mixture into a buttered 9×13-inch casserole dish, smoothing it out so the topping can be evenly distributed later.
Step 7: Add the Cracker Topping and Bake
In a small bowl, melt the remaining butter and toss it with the broken Ritz crackers until each crumb is glossy with butter. Sprinkle this buttery, crispy topping evenly over the casserole for that irresistible golden crunch. Bake in the preheated oven for 25 to 30 minutes, until bubbly and beautifully browned on top.
Step 8: Cool Slightly and Serve
Let the casserole rest for a few minutes once out of the oven so it sets up a bit. This makes serving cleaner and allows the flavors to marry perfectly. Then dig in and enjoy every creamy, comforting spoonful!
How to Serve Creamy Chicken Noodle Casserole Recipe

Garnishes
Adding simple garnishes like freshly chopped parsley or a sprinkle of cracked black pepper can lift the casserole visually and add subtle bursts of fresh flavor. A little color and aroma on top make the dish feel even more inviting.
Side Dishes
This casserole shines boldly on its own but pairs wonderfully with a crisp green salad or steamed vegetables to balance the richness. Roasted broccoli, green beans, or a refreshing cucumber salad add textural contrast and lighten the meal beautifully.
Creative Ways to Present
For a fun twist, try serving individual portions in small ramekins or hollow out a bread bowl for rustic flair. You could even layer the casserole in a clear glass casserole dish to show off its colorful layers, turning every serving into a feast for the eyes as well as the palate.
Make Ahead and Storage
Storing Leftovers
This Creamy Chicken Noodle Casserole Recipe keeps beautifully in the refrigerator for up to 3 days when covered tightly with plastic wrap or stored in an airtight container. The flavors deepen overnight, making leftovers just as satisfying—maybe even better!
Freezing
You can freeze this casserole either before baking or after it has cooled post-baking. Wrap securely with foil and plastic wrap to prevent freezer burn, then store for up to 2 months. Thaw overnight in the fridge for best results before reheating.
Reheating
Reheat leftover casserole in the oven at 350°F (175°C) until warmed through, which retains the crispy topping better than a microwave. If microwaving, cover loosely and reheat in 1-2 minute bursts to avoid drying out the creamy sauce.
FAQs
Can I use different types of noodles for this casserole?
Yes! While extra-wide egg noodles are traditional for the Creamy Chicken Noodle Casserole Recipe, you can substitute other short pasta shapes like rotini or penne. Just be sure to adjust cooking times so they remain al dente and don’t become mushy after baking.
Is it possible to make this vegetarian?
Absolutely. Simply omit the chicken and substitute with hearty vegetables like extra mushrooms, roasted cauliflower, or cooked lentils to keep the creamy texture and satisfy your cravings without meat.
Can I use shredded cheese instead of chopped American cheese?
You can, but American cheese melts uniquely smoothly, which helps create that signature creamy texture. Use processed cheese slices torn into pieces or a similar melty cheese if you can’t find deli-style American cheese for the closest flavor and mouthfeel.
How do I ensure the topping stays crunchy after baking?
Make sure the butter coats the Ritz cracker crumbs thoroughly before sprinkling on top. Baking uncovered allows moisture to escape, keeping the topping golden and crisp. Letting the casserole rest briefly before serving also helps preserve that satisfying crunch.
Can I prepare this casserole entirely ahead of time?
Yes! You can assemble the casserole (except the cracker topping) a day ahead, cover it tightly, and refrigerate. Add the buttered cracker topping just before baking to ensure it stays crisp and golden. This makes it perfect for busy days or entertaining guests.
