Chicken Broth – Helps thin out the sauce while adding depth of flavor. You can swap it with:
- Vegetable broth for a lighter, slightly different taste
- Milk for a creamier, richer sauce

How to Make Creamy Chicken Spaghetti Casserole

Making this creamy, cheesy, and slightly spicy chicken spaghetti casserole is easy and straightforward. Follow these step-by-step instructions to create a rich, flavorful dish that’s perfect for any occasion.

Preparing the Ingredients

Before you start cooking, gather all your ingredients and prep them properly. This will make the process smoother and more efficient.

Cook the spaghetti – Follow the package instructions and cook it al dente (firm to the bite). Since the pasta will continue to cook in the oven, avoid overcooking it. Drain and set aside.
Shred the chicken – If you’re using rotisserie chicken or leftover grilled chicken, shred it into bite-sized pieces. If cooking fresh chicken, boil or bake it until fully cooked, then shred with two forks.
Dice the vegetables – Finely chop the onion, bell pepper, and garlic to ensure they blend well into the sauce.

Cooking the Base Sauce

The creamy, spicy sauce is the heart of this chicken spaghetti casserole.

Sauté the vegetables – Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add diced onion and bell pepper and cook until soft, about 5 minutes. Stir in the minced garlic and sauté for another 30 seconds until fragrant.
Combine the soups and broth – Stir in cream of chicken soup, cream of mushroom soup, and chicken broth until smooth.
Add the seasonings – Mix in chili powder, paprika, cayenne pepper, salt, and black pepper to enhance the flavor. Adjust the spice level to your taste.
Melt the cheese – Stir in 1 ½ cups of cheddar cheese and all of the Monterey Jack cheese until melted and combined.
Incorporate the sour cream – This adds extra richness and a tangy depth to the sauce.

Assembling the Casserole

Now that the sauce is ready, it’s time to bring everything together.

Mix the spaghetti and sauce – Add the cooked spaghetti to the skillet and toss until evenly coated. Make sure every strand is covered in the creamy, spicy sauce.
Transfer to a baking dish – Lightly grease a 9×13-inch baking dish and spread the pasta mixture evenly.
Prepare the crunchy topping – In a small bowl, mix crushed tortilla chips or breadcrumbs with the remaining ¼ cup of cheddar cheese and a pinch of chili powder.
Sprinkle the topping over the casserole – This will create a crispy, golden crust that contrasts beautifully with the creamy interior.

Baking to Perfection

Bake at 375°F (190°C) for 25-30 minutes – The casserole should be bubbly and golden brown on top.
Check for doneness – The cheese should be fully melted, and the top should have a slight crisp.
Let it cool for 5 minutes – This allows the casserole to set, making it easier to serve.

Tips for the Best Chicken Spaghetti Casserole

Making the perfect creamy chicken spaghetti casserole requires a few simple tricks. Follow these expert tips to ensure your dish is extra creamy, flavorful, and perfectly baked every time.

How to Prevent a Dry Casserole

One of the most common mistakes when making baked pasta dishes is ending up with a dry, overcooked casserole. Here’s how to keep it creamy and moist:

Don’t overcook the pasta – Since the spaghetti will continue to cook in the oven, make sure to boil it al dente to prevent mushiness.
Use enough sauce – The mixture may seem extra creamy before baking, but pasta absorbs liquid as it bakes. Make sure to coat the spaghetti thoroughly in sauce.
Cover with foil (optional) – If your casserole starts browning too quickly, cover it with foil for the first 15 minutes of baking, then remove it to crisp up the topping.

Ways to Adjust the Spice Level

This recipe has a perfect balance of spice and creaminess, but you can tweak it to your taste:

For a milder version – Reduce or omit the cayenne pepper, and use mild diced tomatoes instead of ones with green chilies.
For extra heat – Add chopped jalapeños, extra chili powder, or a dash of hot sauce to the sauce before baking.
For a smoky flavor – Swap regular paprika with smoked paprika to add a deeper, richer taste.

Best Pasta Shapes to Use

While spaghetti is traditional in this dish, you can experiment with other pasta types to change the texture:

Linguine or fettuccine – Great for a silky, smooth bite
Penne or rigatoni – Holds onto the sauce well and adds a heartier texture
Rotini or fusilli – Twisted pasta shapes that trap the creamy sauce perfectly

How to Enhance the Cheesy Flavor

If you’re a cheese lover, take your casserole to the next level with these tips:

Use a mix of cheeses – Try adding Colby Jack, mozzarella, or Pepper Jack for extra richness.
Add a creamy cheese layer – Stir in cream cheese or an extra scoop of sour cream for added creaminess.
Broil for extra crispiness – After baking, set your oven to broil for 2-3 minutes to create a golden, bubbly cheese topping.

Now that you have these expert tips, let’s explore how to customize this casserole to fit different dietary needs!

Variations & Customizations

One of the best things about this creamy chicken spaghetti casserole is its versatility. Whether you’re looking for a low-carb alternative, a vegetarian twist, or an extra protein boost, this recipe can be easily adapted to suit your needs.

Keto/Low-Carb Option

If you’re following a low-carb or keto diet, you can still enjoy the flavors of this dish with a few simple swaps:

- Spaghetti squash – A great natural alternative that mimics the texture of pasta.

Choose gluten-free toppings – Use gluten-free breadcrumbs or crushed gluten-free crackers for a crispy finish.

Vegetarian Alternative

Want to make this dish meat-free? Swap the chicken for plant-based protein:

Mushrooms – Sautéed mushrooms add a meaty texture and enhance the umami flavor.
Black beans or chickpeas – A great source of plant-based protein.
Tofu or tempeh – Crumbled and seasoned, they absorb flavors well.
