This easy chicken and noodle casserole is my go-to when the week has gotten away from me. You know those nights. The ones where you need something warm, filling, and on the table without a fuss. Last Tuesday, my pickiest eater asked for seconds. That’s the magic of this dish.
Here’s why this recipe works: it builds flavor in layers. You start by cooking the chicken right in the pot, which leaves those tasty browned bits behind. Then you make a simple, creamy sauce right there. No extra pans. The egg noodles cook directly in that sauce, soaking up all that goodness. It’s a one-pot wonder that feels like a hug.

Why You’ll Love This Easy Chicken and Noodle Casserole
It’s a true one-pot meal. Everything happens in a single Dutch oven or deep skillet. Less washing up means more time for you.
The texture is perfect. The noodles stay tender but never mushy, and the top gets a lovely golden crust. You get that creamy interior with just a bit of crunch.
It’s endlessly adaptable. I’ll share some fun twists later, but the base recipe is a blank canvas. Got some veggies to use up? Toss them in.
Leftovers are arguably better. The flavors meld overnight. Lunch the next day is something to look forward to.
Ingredients for Your Easy Chicken and Noodle Casserole
- 1 tablespoon olive oil
- 1.5 pounds boneless, skinless chicken breasts, cut into 1-inch pieces
- 1 teaspoon salt, divided
- 1/2 teaspoon black pepper
- 1 medium yellow onion, diced
- 3 cloves garlic, minced
- 8 ounces cremini mushrooms, sliced
- 2 tablespoons all-purpose flour
- 2 cups chicken broth
- 1 cup whole milk
- 1/2 cup sour cream
- 1 teaspoon dried thyme
- 8 ounces wide egg noodles (the classic kind for this easy chicken and noodle casserole)
- 1 cup frozen peas
- 1.5 cups shredded sharp cheddar cheese, divided
- 1/4 cup grated Parmesan cheese
- 2 tablespoons chopped fresh parsley, for garnish
Note on the noodles: Don’t use the “no-boil” kind. Standard dried egg noodles are perfect—they hold their shape and cook evenly in the sauce.
Quick swap: No sour cream? Full-fat plain Greek yogurt works beautifully. It adds the same tang and creaminess.
How to Make This Easy Chicken and Noodle Casserole
- Brown the chicken. Heat the olive oil in a large Dutch oven or deep oven-safe skillet over medium-high heat. Pat the chicken pieces dry and season with 1/2 teaspoon of the salt and all the pepper. Add to the hot pot in a single layer. Let it sear without moving for 3-4 minutes, until you get a deep golden-brown crust. Flip and cook another 2-3 minutes. It doesn’t need to be cooked through yet. Remove to a plate. You should see those beautiful browned bits stuck to the bottom of the pot. That’s flavor.
- Build the base. In the same pot, add the onion, garlic, and mushrooms. Cook, stirring occasionally, for about 5 minutes. The mushrooms will release their liquid and start to turn golden. The kitchen will smell incredible. Sprinkle the flour over the veggies and cook, stirring constantly, for 1 full minute. This cooks out the raw flour taste and is the secret to a smooth, thick sauce for your easy chicken and noodle casserole.
- Create the creamy sauce. Slowly pour in the chicken broth while scraping the bottom of the pot with a wooden spoon. All those browned bits will loosen and dissolve into the sauce. Stir in the milk, sour cream, dried thyme, and remaining 1/2 teaspoon of salt. Bring to a gentle simmer. The sauce will thicken slightly.
- Cook the noodles. Stir in the uncooked egg noodles and the frozen peas. Make sure the noodles are mostly submerged. Return the browned chicken (and any juices) to the pot. Reduce heat to medium-low, cover, and let it bubble gently for 10-12 minutes. Stir once halfway through to prevent sticking. The noodles should be tender and have absorbed much of the liquid.
- Add the cheese and bake. Preheat your broiler. Remove the pot from the heat. Stir in 1 cup of the cheddar cheese and all the Parmesan until melted and creamy. Taste and adjust seasoning. Sprinkle the remaining 1/2 cup cheddar evenly over the top. This final step for your easy chicken and noodle casserole creates that irresistible, bubbly, golden top.
- Broil to perfection. Place the pot under the broiler for 2-4 minutes. Watch it closely! You want the cheese melted and spotted with deep golden brown, not burned. It happens fast. You’ll hear it sizzle. Pull it out when the top is gloriously blistered. Let it sit for 5 minutes—this helps it set. Garnish with fresh parsley.

Tips & Variations for Your Casserole
Make it ahead: Assemble the casserole completely through step 5 (before broiling). Cover and refrigerate for up to 24 hours. Let it sit at room temp for 30 minutes before broiling. You may need to add 2-3 minutes under the broiler since it’s cold.
Storage & Reheating: Leftovers keep for 3-4 days in the fridge. Reheat individual portions in the microwave with a splash of broth to keep it creamy. For a larger amount, reheat covered in a 350°F oven until warmed through.
Add more veggies: Stir in a cup of chopped broccoli florets or diced carrots with the mushrooms. For a different twist, check out this Easy Cheesy Cajun Chicken Rotini Skillet for another veggie-packed idea.
Switch up the protein: Use leftover shredded rotisserie chicken or cooked turkey. Add it in step 5 with the cheese, since it’s already cooked. For more inspiration on simple, satisfying dinners, I always find great ideas over at Lilly’s Bites.
Creamier version: For an even richer dish, substitute one can of condensed cream of mushroom soup for 1 cup of the broth. It’s a classic shortcut that works.
Remember, the best part of this easy chicken and noodle casserole is how forgiving it is. Don’t stress about perfection.
