Ingredients You’ll Need
- Rotini pasta or medium egg noodles: These provide the hearty base of the casserole. Both shapes hold the creamy sauce beautifully. Cook until just al dente so they don’t become mushy in the oven.
- Unsalted butter: Creates a rich base for sautéing the vegetables and preparing the cheese sauce.
- Baby portabella mushrooms: Add earthy flavor and a meaty texture that pairs wonderfully with chicken.
- Small onion: Brings natural sweetness and savory depth to the sauce.
- Garlic: Freshly minced garlic adds aromatic flavor and makes the creamy sauce even more delicious.
- All-purpose flour: Helps thicken the broth and cream into a smooth, rich sauce.
- Low-sodium chicken broth: Adds savory flavor and balances the richness of the heavy cream.
- Heavy cream: Gives the sauce its smooth, velvety texture.
- Seasoned salt: Adds a balanced blend of seasoning to the chicken and creamy sauce.
- Black pepper: Provides a gentle warmth that complements the cheese and mushrooms.
- Onion powder: Enhances the savory flavor of the sauce.
- Dried Italian seasoning: Adds a fragrant blend of herbs that works beautifully with chicken and pasta.
- Shredded cheese: Monterey Jack, Gouda, or Swiss cheese melts into the sauce and creates a deliciously cheesy casserole. Keep some extra for the topping.
- Chopped rotisserie chicken: Makes this recipe convenient while adding tender, flavorful protein. Leftover cooked chicken works just as well.
- Petite peas: Add a touch of sweetness, color, and texture to every bite.
- Grated Parmesan cheese: Sprinkled over the top, Parmesan adds a savory finish and helps create a golden, flavorful crust.
How to Make Chicken Pasta Bake
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 350°F (175°C).
Lightly coat a 13 × 9-inch baking dish with cooking spray and set it aside. Preparing the dish now makes assembling the casserole much easier.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil. Add the rotini or egg noodles and cook according to the package directions until just al dente.
Drain the pasta thoroughly and set it aside.
Helpful tip: Avoid overcooking the pasta. It will continue cooking in the oven, so keeping it slightly firm helps prevent a mushy casserole.
Step 3: Sauté the Mushrooms and Onion
Melt the butter in a large pot over medium heat.
Add the sliced or chopped baby portabella mushrooms and finely diced onion. Cook for approximately 5–7 minutes, stirring occasionally, until the mushrooms are tender and the onion has softened.
Stir in the minced garlic and cook for another minute until fragrant.
Step 4: Make the Creamy Sauce
Sprinkle the flour over the cooked vegetables. Reduce the heat to low and stir until the flour is absorbed into the butter and vegetables.
Gradually add the chicken broth and heavy cream, stirring continuously to prevent lumps from forming.
Increase the heat to medium-high and bring the mixture to a gentle boil. Once it begins bubbling, immediately reduce the heat to low.
Simmer for approximately 5 minutes, stirring occasionally, until the sauce thickens.
Step 5: Season and Add the Cheese
Stir in the seasoned salt, black pepper, onion powder, and dried Italian seasoning.
Turn off the heat and add 2 cups of shredded cheese. Stir until the cheese melts completely into the sauce, creating a smooth and creamy mixture.
Taste the sauce and adjust the seasoning if needed.
Step 6: Assemble the Casserole
Spread half of the cooked pasta evenly across the bottom of your prepared baking dish.
Add half of the chopped chicken and half of the thawed peas. Spoon half of the creamy cheese sauce over the top.
Repeat the layers with the remaining pasta, chicken, peas, and sauce.
Finish by sprinkling the remaining 1 cup of shredded cheese evenly over the casserole, followed by the grated Parmesan.
Step 7: Bake Until Golden and Bubbly
Place the baking dish in the preheated oven and bake for 25–30 minutes, or until the casserole is hot throughout, bubbling around the edges, and lightly golden on top.
If you’d like a more golden cheese topping, you can briefly place the casserole under the broiler, watching carefully to prevent burning.
Step 8: Rest and Serve
Remove the Chicken Pasta Bake from the oven and let it rest for approximately 5 minutes before serving.
This short resting time allows the sauce to settle slightly, making it easier to scoop and serve.
Enjoy warm, cheesy portions with your favorite salad or vegetable side!

Tips for Making the Best Chicken Pasta Bake
- Cook pasta al dente: Slightly firm pasta holds its shape better after baking.
- Use rotisserie chicken: It’s a convenient shortcut that saves cooking time and adds plenty of flavor.
- Thaw the peas first: Excess moisture from frozen peas can make the sauce watery. Thaw and drain them before assembling.
- Add broth gradually: Slowly incorporating the broth and cream helps create a smooth sauce without lumps.
- Melt the cheese off the heat: Adding shredded cheese after turning off the heat helps prevent the sauce from becoming grainy.
- Choose a good melting cheese: Monterey Jack, Gouda, and Swiss all work beautifully. Freshly shredded cheese often melts more smoothly than pre-shredded varieties.
- Let it rest before serving: Five minutes of resting makes the casserole easier to portion.
- Check the center: Make sure the casserole is heated through before serving, especially if the ingredients were prepared ahead of time.
Equipment Needed
- 13 × 9-inch baking dish: Provides plenty of room for layering the pasta, chicken, vegetables, and sauce.
- Large pot: Useful for cooking the pasta and preparing the creamy cheese sauce.
- Colander: Helps drain the pasta thoroughly.
- Wooden spoon or silicone spatula: Perfect for stirring the sauce and combining ingredients.
- Whisk: Helps incorporate the broth and cream smoothly.
- Cutting board and sharp knife: Make chopping the onion, mushrooms, and garlic easier.
- Measuring cups and spoons: Help keep the ingredient quantities accurate.
Delicious Chicken Pasta Bake Variations
- Chicken and Bacon Pasta Bake: Add cooked, crispy bacon pieces to the chicken and pasta layers for a smoky, savory flavor. Bacon also adds a delicious texture to the creamy casserole.
- Chicken and Broccoli Pasta Bake: Replace the peas with steamed broccoli florets or use a combination of both. Broccoli pairs wonderfully with chicken and melted cheese.
- Cheesy Cheddar Chicken Pasta Bake: Swap the Monterey Jack, Gouda, or Swiss for sharp cheddar cheese. It creates a stronger cheese flavor and a delicious golden topping.
- Turkey Pasta Bake: Use leftover cooked turkey instead of chicken. This is a great way to turn holiday leftovers into a comforting family dinner.
- Extra Creamy Chicken Pasta Bake: For an even richer sauce, use 2 cups of chicken broth and 2 cups of heavy cream instead of the original liquid quantities.
- Chicken Pasta Bake with Spinach: Stir fresh baby spinach into the sauce just before assembling the casserole. It wilts quickly and adds color and extra vegetables.
What to Serve with Chicken Pasta Bake
This creamy casserole is filling on its own, but a fresh side dish helps balance its rich, cheesy flavor.
- Fresh green salad: A crisp salad with lettuce, cucumber, tomatoes, and a light vinaigrette adds freshness to the meal.
- Garlic bread: Warm, buttery garlic bread is perfect for scooping up any extra cheese sauce.
- Roasted green beans: Their slightly crisp texture makes a delicious contrast to the creamy pasta.
- Steamed broccoli: A simple vegetable side that complements the chicken and cheese.
- Roasted carrots: Their natural sweetness pairs beautifully with the savory sauce.
- Caesar salad: Crisp romaine, Parmesan, and creamy dressing make a classic pairing.
- Dinner rolls: Soft, fluffy rolls are ideal for a comforting family-style dinner.
Frequently Asked Questions
Can I use rotisserie chicken for Chicken Pasta Bake?
Absolutely! Rotisserie chicken is one of the easiest options for this recipe. Simply remove the skin and bones, chop or shred the cooked meat, and add it to the casserole layers. You can also use cooked chicken breasts, thighs, or leftover roasted chicken.
Can I use a different type of pasta?
Yes! Rotini and medium egg noodles both work well, but you can also use penne, fusilli, or other short pasta shapes. Choose a shape that holds the creamy sauce nicely, and cook it just until al dente.
Can I make Chicken Pasta Bake ahead of time?
Yes. You can assemble the casserole, cover it tightly, and refrigerate it before baking. For the best texture, bake within 24 hours.

How do I reheat Chicken Pasta Bake without drying it out?
For individual portions, microwave until hot, adding a small splash of chicken broth or cream to restore moisture if needed. To reheat a larger portion, cover the baking dish with foil and warm it in a 325°F (165°C) oven until heated through.
