Easy Cheesy Chicken Spaghetti

This comforting chicken spaghetti combines the heartiness of pasta with the bold flavors of Tex-Mex cuisine, creating a crowd-pleasing casserole that will quickly become a family favorite. With its creamy, cheesy sauce and perfectly seasoned chicken, this dish transforms everyday ingredients into something truly special.

I stumbled upon this recipe while looking for ways to jazz up traditional chicken spaghetti. After a few disappointing batches that lacked flavor, the simple swap of salsa for Rotel and the addition of taco seasoning completely transformed this dish. My pickiest eater, who typically pushes pasta around his plate, asked for seconds - the ultimate seal of approval in our household.

Ingredients

• Angel hair pasta – The delicate strands create the perfect base, absorbing the creamy sauce without becoming heavy. Its lighter texture balances the rich toppings beautifully.
• Cooked chicken – Using pre-cooked grilled chicken adds a wonderful smoky flavor that elevates the entire dish. The slight char from grilling adds depth that boiled or plain chicken simply can't match.
• Cream of chicken soup – This pantry staple creates a rich, velvety sauce base without any fuss. Its mild flavor allows the other ingredients to shine while providing that comforting creaminess.
• Salsa – The game-changing ingredient that brings freshness, acidity, and complex flavor. Unlike Rotel, a good salsa already contains seasonings and flavor development that infuse the entire dish.
• Sour cream – Adds luxurious creaminess and a subtle tang that balances the richness of the cheese and soup. It creates that irresistible velvety texture that makes you come back for more.
• Mexican cheese blend – Melts beautifully, creating those coveted cheese pulls while adding savory depth. The combination of cheeses provides more complex flavor than a single variety would.
• Taco seasoning – This simple addition ties everything together with its blend of cumin, chili powder, and other spices that complement the salsa perfectly.

Step-by-Step Instructions

Prep your oven and baking dish –

Preheat your oven to 350°F and spray a 9×13 baking dish with nonstick cooking spray. This preparation ensures even cooking and easy serving later on.

Cook the pasta –

Bring a large pot of salted water to a boil and cook half a box of angel hair pasta according to package directions, usually about 4-5 minutes. For the best texture, aim for al dente since the pasta will continue cooking in the oven.

Drain thoroughly –

Once cooked, drain the pasta well to prevent excess water from diluting your creamy sauce. Return the pasta to the hot pot with the heat turned off – the residual warmth will help the ingredients combine more easily.

Add protein and soup base –

Add your diced cooked chicken and cream of chicken soup to the warm pasta. The heat from the pasta will help the soup melt and coat each strand evenly.

Incorporate creamy elements –

Stir in the salsa and sour cream, which add moisture and flavor while creating that irresistible creamy texture. The cold ingredients will cool the mixture slightly, making it easier to handle.

Add cheese and seasoning –

Mix in 1 cup of the Mexican cheese blend and the taco seasoning. Stir well for a couple of minutes to ensure even distribution of flavors throughout the pasta mixture.

Transfer to baking dish –

Pour the combined mixture into your prepared baking dish, spreading it evenly to ensure consistent cooking throughout.

Top with remaining cheese –

Sprinkle the remaining cheese over the top to create that beautiful golden, bubbly crust everyone loves. A light sprinkle of dried parsley adds a touch of color and freshness.

Cover and bake –

Cover the dish with nonstick aluminum foil (or regular foil sprayed with cooking spray) to prevent the cheese from sticking and bake for about 25 minutes until hot and bubbly throughout.

Rest briefly before serving –

Allow the casserole to rest for about 5 minutes after removing from the oven. This brief rest allows the sauce to set slightly, making for neater servings.

Pin it

The transformation that happens in the oven is magical – the individual components meld into a cohesive, flavor-packed dish where each bite delivers creamy, cheesy comfort with hints of Tex-Mex spice. The top develops a beautiful golden crust while the interior remains creamy and rich.

My grandmother always said that the best recipes are ones that evolve over time, and this chicken spaghetti is proof of that wisdom. What began as a bland, forgettable casserole transformed into our family's most requested meal with just a few thoughtful swaps. The first time I served this version at a neighborhood potluck, three different people asked for the recipe before the evening was over.

Perfect Pairings

This hearty casserole pairs beautifully with lighter sides that balance its richness. A simple green salad with tangy vinaigrette provides refreshing contrast, while garlic bread is perfect for sopping up every last bit of the creamy sauce. For a complete Tex-Mex themed dinner, serve with a side of black beans or Mexican street corn.

Make-Ahead Magic

This recipe shines as a make-ahead option for busy weeks. You can assemble the entire casserole up to two days before baking - simply cover tightly and refrigerate. When ready to bake, allow it to sit at room temperature for about 30 minutes, then bake as directed, adding about 10-15 minutes to the cooking time if it's still cold from the refrigerator.

Freezer-Friendly Features

For even longer storage, this casserole freezes beautifully before or after baking. For best results, cool completely if baked, then wrap tightly with plastic wrap and foil. Freeze for up to three months. Thaw overnight in the refrigerator before reheating, covered, in a 325°F oven until hot throughout.

After preparing this dish countless times, I've found it's one of those rare recipes that pleases everyone from picky children to discerning adults. There's something about the combination of familiar pasta with unexpected Tex-Mex flavors that makes it both comforting and exciting. It's become my go-to for new neighbors, family gatherings, and those nights when only a cheesy, creamy casserole will satisfy. The best part? It comes together so easily that it never feels like a chore to prepare, even on busy weeknights when cooking is the last thing you want to do.
