Ingredients for Creamy Chicken Spaghetti Casserole

Gathering your ingredients is the first step to this delicious homemade chicken spaghetti bake. You’ll need:

4 cups cooked chicken, shredded or diced – rotisserie chicken is a fantastic shortcut here!
1 pound spaghetti noodles – cooked al dente, as they’ll continue cooking in the oven.
1 (10.5 ounce) can cream of mushroom soup – this is a classic base for that signature creamy texture.
1 (10.5 ounce) can cream of chicken soup – another layer of creamy goodness that makes this a true chicken spaghetti with cream of mushroom soup dish.
1 (10 ounce) can diced tomatoes with green chilies (Rotel) – for a little zip and flavor, but you can omit if you prefer no tomatoes.
2 cups chicken broth – helps create the perfect sauce consistency.
2 cups shredded cheddar cheese, divided – because what’s a casserole without cheese?
1/2 cup chopped onion (optional) – adds a nice savory depth.
1/2 cup diced bell pepper (optional) – for a touch of sweetness and color.
Salt and pepper to taste – essential for bringing out all the flavors.
2 tablespoons butter or oil (optional) – if you’re sautéing the optional veggies.

How to Make Easy Chicken Spaghetti Recipe

This simple recipe turns everyday ingredients into a crowd-pleasing meal. Let’s get this delicious baked chicken spaghetti assembled!

Step 1: First things first, preheat your oven to 350°F (175°C). While the oven heats up, lightly grease a 9×13-inch baking dish. This prevents our wonderful chicken spaghetti casserole from sticking.
Step 2: Get your spaghetti noodles cooking according to the package directions. I like to cook them just until they’re al dente, meaning they still have a slight bite, because they’ll finish cooking in the oven. Drain them well once they’re ready.
Step 3: If you’re adding onion and bell pepper for extra flavor and texture, now’s the time to sauté them. Toss them into a skillet with a little butter or oil over medium heat and cook until they’re nice and tender, about 5-7 minutes. The kitchen will start to smell amazing!
Step 4: In a large mixing bowl, combine the creamy bases: the cream of mushroom soup and cream of chicken soup. Pour in the chicken broth and the diced tomatoes with green chilies (Rotel). Stir it all together until it looks like a smooth, luscious sauce.
Step 5: Now, add the star of the show – your cooked chicken! Stir in the sautéed veggies (if you used them) and 1 cup of the shredded cheddar cheese. Season this mixture with salt and pepper to your liking.
Step 6: Gently fold in the cooked spaghetti noodles. Make sure every strand gets coated in that rich, creamy sauce. This is where the magic starts to happen for our baked chicken spaghetti.
Step 7: Pour the entire chicken spaghetti casserole mixture into your prepared baking dish. Spread it out evenly.
Step 8: Top the casserole generously with the remaining 1 cup of shredded cheddar cheese. This creates that irresistible golden, bubbly cheese crust we all love on a baked chicken spaghetti.
Step 9: Bake for 30-35 minutes. You’re looking for the casserole to be bubbly around the edges and the cheese on top to be beautifully melted and lightly golden brown.
Step 10: Once it’s out of the oven, let this delightful chicken spaghetti casserole rest for about 5 minutes. This allows the flavors to meld and makes it easier to serve. Enjoy your homemade comfort food!

Pro Tips for the Best Homemade Chicken Spaghetti Casserole

Want to elevate your chicken spaghetti bake? Here are a few of my go-to tips for making it absolutely perfect every time:

Don’t overcook the spaghetti! Aim for al dente, as it will continue to soften in the oven, preventing mushy pasta.
Using a rotisserie chicken is a fantastic time-saver for this chicken spaghetti casserole.
For an extra creamy texture, consider adding a splash of milk or heavy cream to the soup mixture.
If you don’t have cream of mushroom or chicken soup, a homemade béchamel sauce can be substituted. For more on making sauces from scratch, check out this guide to sauces.

What’s the secret to perfect Chicken Spaghetti Casserole?

The real secret to a perfect, cheesy chicken spaghetti casserole is in the balance of creamy sauces and the quality of your cheese. Using both cream of mushroom and cream of chicken soup creates a luscious base, and don’t skimp on the cheddar!

Can I make Chicken Spaghetti Casserole ahead of time?

Absolutely! You can assemble this entire chicken spaghetti casserole up to 24 hours in advance. Just cover it tightly with plastic wrap and refrigerate. You’ll likely need to add an extra 5-10 minutes to the baking time since it will be cold.

How do I avoid common mistakes with Baked Chicken Spaghetti?

The biggest pitfall is overcooking the pasta, which leads to a mushy texture. Also, be sure to season generously; under-seasoning can make the casserole taste bland. Finally, don’t skip the resting time after baking; it helps everything set up beautifully. For more on food safety and storage, consult these guidelines.

Frequently Asked Questions About Chicken Spaghetti Casserole

What if I don’t have cream of mushroom or cream of chicken soup?

No worries if you’re missing those classic canned soups! You can easily make your own creamy base. Start by making a roux with 4 tablespoons of butter and 4 tablespoons of all-purpose flour. Whisk until smooth, then gradually add 3 cups of milk and 1 cup of chicken broth, stirring constantly until thickened. This homemade sauce is a fantastic substitute for the canned soups and is key to understanding how to make chicken spaghetti casserole from scratch without the traditional ingredients. For more on making a roux, see this basic roux guide.

Can I make this chicken spaghetti casserole vegetarian?

Yes, you absolutely can! To make a vegetarian chicken spaghetti casserole, simply omit the chicken and use vegetable broth instead of chicken broth. You can add extra vegetables like mushrooms, peas, corn, or spinach for more texture and flavor. Some shredded or cubed firm tofu or even chickpeas can also add a nice protein boost to your vegetarian version.

How do I make a spicier Chicken Spaghetti Casserole?

For those who love a little heat, making this casserole spicier is simple! The Rotel already adds a nice kick, but you can amp it up by using the “hot” variety of Rotel, adding a pinch of cayenne pepper to the sauce mixture, or stirring in a tablespoon or two of your favorite hot sauce. A little finely diced jalapeño sautéed with the optional onions and peppers also works wonders for an extra spicy bite!

Can I use different pasta shapes for this recipe?

Definitely! While spaghetti is traditional, feel free to get creative with your pasta shapes. Penne, rotini, elbow macaroni, or even medium shells work wonderfully in this chicken spaghetti casserole. Just make sure to cook them al dente, as they will continue to cook in the oven, just like the spaghetti would. For pasta cooking tips, check out this pasta guide.

Variations of Chicken Spaghetti Casserole You Can Try

This classic dish is incredibly versatile, and I love experimenting with different twists! Here are a few of my favorite ways to change up this chicken spaghetti casserole:

Spicy Southwest Twist: Swap the Rotel for a can of diced green chilies and add a pinch of cumin and chili powder to the sauce. You can also use pepper jack cheese for an extra kick.
Chicken Spaghetti Casserole No Tomatoes: If you’re not a fan of tomatoes or Rotel, you can easily omit them. Just add an extra cup of chicken broth and perhaps some sautéed mushrooms or peas for added flavor and texture. This creates a wonderfully creamy, tomato-free version.
Creamy Broccoli Cheddar Bake: Add a cup or two of steamed broccoli florets to the noodle mixture. Swap the cheddar cheese for a blend of cheddar and Monterey Jack for a delicious broccoli cheddar variation.
Slow Cooker Chicken Spaghetti: For an even easier prep, combine all ingredients (except the top cheese layer) in your slow cooker. Cook on low for 3-4 hours or high for 2-3 hours. Stir in the cheese during the last 30 minutes of cooking.
