Chicken Spaghetti Creamy Cheese
There's something deeply comforting about a dish that tastes like a warm hug on a plate-this Chicken Spaghetti Creamy Cheese does exactly that. Home cooks adore it for its creamy, cheesy indulgence paired with tender chicken and a subtle kick from diced tomatoes and green chilies. It's the kind of meal that feels special but comes together effortlessly, making it perfect for weeknight dinners, potlucks, or even a cozy Sunday supper. The golden, bubbly top and silky cheese sauce make it irresistible to both kids and adults alike.
What Makes This Recipe Special
- The sauce combines roux-based creaminess with melted cream cheese and cheddar, creating a luxuriously smooth texture that clings beautifully to spaghetti.
- Diced tomatoes and green chilies add a bright, tangy contrast to the rich cheese sauce, balancing the dish without overpowering it.
- The recipe uses a two-pan method-sautéing chicken first, then building the sauce in the same skillet-to maximize flavor by incorporating fond from the browned chicken.
- Baking the dish with a layer of mozzarella on top ensures a perfectly melted, slightly gooey finish that's impossible to resist.
Ingredients
2 smallboneless skinless chicken breasts
2 teaspoonsItalian seasoning
Salt, to taste
Pepper, to taste
2 tablespoonsolive oil
4 tablespoonsbutter
1 smallyellow onion, diced
3 clovesgarlic, minced
4 tablespoonsflour
1 ½ cupschicken broth
¾ cupmilk
4 ozcream cheese, softened
1 cupcheddar cheese, shredded
10 ozdiced tomatoes and green chilies (drained or with juice for thinning)
8 ozthin spaghetti
1 cupmozzarella cheese, shredded
Red pepper flakes, for garnish
Chopped parsley, for garnish
Instructions
1
Preheat oven to 400 degrees Fahrenheit.
2
Slice the chicken breasts in half lengthwise to create thinner slices. Pat dry and season with salt, pepper, and Italian seasoning. Heat olive oil in a pan over medium-high heat. Sear chicken for 5-6 minutes on each side. Remove from the pan, let cool, and dice into bite-sized pieces.
3
Reduce heat to medium-low. Melt butter in the same pan, scraping up any browned bits from the chicken. Add onions and cook until softened, about 4 minutes. Stir in garlic and cook for an additional minute.
4
Sprinkle flour over the onions and stir to coat. Cook for 2 minutes until the raw flour smell subsides.
5
Gradually add chicken broth in small splashes, stirring between each addition to maintain a smooth consistency. Add milk in the same manner, whisking continuously until smooth.
6
While the sauce simmers, bring a pot of water to a boil. Cook spaghetti according to package instructions, then drain.
7
Add softened cream cheese to the sauce and stir until fully melted and smooth. Sprinkle in shredded cheddar cheese and stir to combine. Add the diced tomatoes along with the cooked chicken. Stir to combine.
8
Add cooked spaghetti to the sauce and mix well. If the pan is not oven-safe, transfer the mixture to a greased 9x13-inch casserole dish.
9
Top with mozzarella cheese. Bake uncovered for 15 minutes. For a browned top, broil at 475 degrees Fahrenheit for 1-2 minutes, keeping a close watch.
10
Remove from the oven and garnish with red pepper flakes and chopped parsley. Serve with garlic bread if desired.
Essential Tips
Don't skip the fond
When you remove the chicken from the pan, don't wipe it out! The browned bits (fond) add deep, savory flavor to the sauce. Deglaze with butter to scrape them up before adding onions.
Sauce consistency is key
The sauce should coat the back of a spoon but still be pourable. If it thickens too much after adding spaghetti, stir in a splash of warm milk to loosen it before baking.
Use room-temperature cream cheese
Cold cream cheese can seize up and create lumps in the sauce. Let it sit out for 15-20 minutes before using, or soften it in 10-second bursts in the microwave.
Undercook the spaghetti slightly
Since the pasta will bake further in the oven, cook it 1-2 minutes less than package instructions suggest. This prevents a mushy texture after baking.
Broil for a crispy top
Watch the broiler closely! Skim milk solids can burn quickly. Keep the oven door slightly ajar and broil for just 1-2 minutes to avoid a bitter taste.
Smart Swaps & Variations
Spicy Kick
Swap the diced tomatoes and green chilies for 1 cup of roasted poblano peppers and ½ cup diced jalapeños to turn up the heat without overpowering the creamy sauce.
Vegetarian
Replace the chicken with 2 cups of sautéed mushrooms and 1 cup of spinach added to the sauce before baking for a hearty, meat-free version.
Lighter Cheese
Use a mix of ½ cup reduced-fat cheddar and ½ cup grated parmesan for a lower-fat option that still delivers bold flavor.
Extra Creamy
Stir ½ cup of sour cream into the sauce after adding the cheddar to create an even richer, velvety texture.
What to Serve With This
- Crusty garlic bread or garlic knots to soak up the cheesy sauce
- A crisp arugula salad with lemon vinaigrette to cut through the richness
- Roasted broccoli or garlic green beans for a balanced, veggie-packed meal
- A cold glass of sparkling apple cider or a dry white wine like Pinot Grigio
Storage & Reheating
Storage
Store leftovers in an airtight container in the fridge for up to 3 days. The dish will thicken as it cools, so add a splash of milk when reheating to restore its creamy texture.
Reheating
Cover the dish with foil and reheat in a 350°F oven for 15-20 minutes, stirring halfway through. For a quick fix, microwave individual portions in 1-minute intervals, stirring between each burst to prevent hot spots.
Expert Chef Tips
- Toast the flour in the butter for an extra 2-3 minutes at the beginning to remove its raw taste and deepen the sauce's flavor.
- For a more even melt, shred the cheddar cheese yourself instead of using pre-shredded varieties, which often contain anti-caking agents that prevent smooth blending.
- If the sauce separates while simmering, whisk in a small ice cube-it will dissolve quickly and help emulsify the mixture without thinning the sauce excessively.
Equipment You’ll Need
- Large oven-safe skillet or Dutch oven (12-inch)
- Medium pot for boiling spaghetti
- Whisk for smoothing the sauce
- 9x13-inch casserole dish (if not using an oven-safe skillet)
Nutritional Benefits
- High in protein from chicken and calcium from cheese, providing sustained energy and bone support.

Frequently Asked Questions
Can I use pre-cooked chicken to save time?
Absolutely! Use 2 cups of shredded rotisserie chicken and add it to the sauce in step 7, just before mixing in the spaghetti. This reduces the total time to about 30 minutes.
What's the best cheese substitute for cheddar?
Gouda or Monterey Jack work well for a milder flavor, while pepper jack adds a subtle kick. Avoid pre-shredded cheeses with anti-caking agents, as they can make the sauce grainy.
Can I make this dish ahead and bake it later?
Yes! Assemble the dish up to step 8, cover it tightly, and refrigerate for up to 24 hours. Add 5-10 minutes to the baking time if starting from cold.
Why are there lumps in my sauce?
Lumps usually form if the flour isn't fully cooked or if the cream cheese wasn't softened. Cook the flour in butter for 2-3 minutes to eliminate raw taste, and soften the cream cheese at room temperature.
Can I freeze this dish?
Freezing is possible but can make the sauce grainy when thawed. For best results, assemble the dish, bake it, let it cool, then freeze individual portions. Thaw overnight in the fridge and reheat in the oven.
How do I adjust the spice level?
For more heat, add ½ teaspoon of cayenne pepper to the chicken seasoning or mix in 1-2 teaspoons of hot sauce with the broth. For less heat, drain the diced tomatoes and green chilies well.
What's the ideal pasta shape?
Spaghetti works best for its ability to cling to the sauce, but you can substitute linguine, fettuccine, or even penne for a different texture.
Can I use evaporated milk instead of regular milk?
Yes! Substitute the ¾ cup milk with ½ cup evaporated milk for a richer, creamier sauce. Add a splash of water if the sauce becomes too thick.
