The Cheese Whiz is non-negotiable here—only the original 16oz jar gives that signature velvety texture. I grab mine at Walmart or any major grocery chain (it’s usually near the deli meats). For the chicken, breast meat stays tender when cut into even, bite-sized pieces. Don’t overcrowd the pan or it’ll steam instead of brown. The pasta? Any spaghetti works, but I prefer De Cecco or Barilla for that perfect al dente bite.
No whole milk? 2% works in a pinch but the sauce won’t be as rich. Swap the Italian seasoning for equal parts dried oregano and basil. Fresh garlic is ideal, but jarred minced garlic saves time (use 1 tsp per clove). Want extra veggies? Diced mushrooms or spinach blend right in. The red bell pepper adds color and crunch—skip it if you’re short on time (or sub frozen peas).
Leftovers keep 4-5 days in the fridge, and honestly taste better the next day. Freeze portions for up to 3 months—just thaw in the fridge overnight before reheating. The sauce thickens as it cools, so add a splash of milk when warming it up.

Step-by-Step Instructions for Chicken Spaghetti With Cheese Whiz
Here’s how to nail that creamy, comforting texture this dish is famous for.
Step 1: Cook and Season the Chicken
Cut the 1.5 lb boneless skinless chicken breasts into bite-sized pieces. Heat a large skillet over medium-high heat and add 2 tablespoons of the 0.25 cup unsalted butter. When the butter melts and foams, add the chicken in a single layer.
Season with 1 tsp salt and 0.5 tsp ground black pepper, then 1 tsp dried Italian seasoning. Cook for 6-8 minutes, stirring occasionally, until the chicken is no longer pink inside and lightly browned. Transfer to a plate and set aside.
Step 2: Sauté the Vegetables and Build the Roux
In the same skillet, melt the remaining butter over medium heat. Add the finely diced yellow onion and diced red bell pepper, cooking for 4-5 minutes until they soften and start to turn translucent.
Stir in the 3 minced garlic cloves and cook for 30 seconds until fragrant. Sprinkle in the 2 tbsp all-purpose flour and whisk constantly for 1-2 minutes to form a light golden roux—this thickens the sauce and removes the raw flour taste.
Step 3: Create the Creamy Cheese Sauce
Slowly pour in the 1 cup chicken broth and 1.5 cups whole milk, whisking continuously to prevent lumps. Bring the mixture to a gentle simmer over medium heat and cook for 3-4 minutes until it thickens slightly.
Reduce heat to low and add the entire 16 oz Cheese Whiz jar. Stir until fully melted and smooth. The sauce should coat the back of a spoon and have a velvety, glossy appearance—this is the heart of the dish’s comfort factor.
Step 4: Combine and Finish
Add the cooked chicken back into the skillet along with the 12 oz spaghetti (cooked al dente according to package instructions). Stir everything together until the pasta is fully coated in the sauce.
Let it all warm through for 2-3 minutes** over low heat. Taste and adjust seasoning if needed. The sauce should cling to the spaghetti, and every bite should deliver that rich, cheesy comfort you’re after.
Step 5: Serve with Parmesan
Transfer to serving plates and top each portion with a generous sprinkle of 0.5 cup grated Parmesan cheese. The residual heat will slightly melt the Parmesan, adding another layer of cheesy goodness.
Serve immediately while hot. The dish should have a creamy, cohesive sauce that’s neither too thick nor runny, with the chicken and bell peppers providing pops of color and texture throughout.
Pro Tips For Making Chicken Spaghetti Recipe With Cheese Whiz
- Shred Chicken Hot: Poach or boil the chicken breasts in the broth until just done (165°F), then shred while still warm—it absorbs the cheese sauce better than cold chicken.
- Thin the Cheese: Warm the Cheese Whiz with milk in a saucepan over low heat, adding milk a tablespoon at a time until it reaches a pourable consistency, but not so thin it slides off the noodles.
- Skip Overcooked Noodles: Cook the spaghetti 1-2 minutes less than package instructions—it’ll finish softening in the hot cheese sauce without turning mushy.
- Use Broth for Flavor: Reserve a cup of the chicken poaching broth to stir into the cheese sauce—it thins it slightly and adds depth without watering it down.
Best Sauces and Condiments for This chicken spaghetti recipe with cheese whiz
Classic Bread Dippers
Warm garlic bread or breadsticks are perfect for soaking up the creamy sauce. I love using a baguette toasted with garlic butter—it adds a crispy contrast. Even my daughter Lily can’t resist dipping her bread into this velvety sauce. 🥖
Fresh Herb Garnishes
Fresh parsley or chives add a bright, fresh note that cuts through the richness. Finely chop about 2 tbsp and sprinkle on top just before serving. It’s a small touch that makes the dish look and taste gourmet.
Hot Sauce Kick
For a little heat, I keep Tabasco or Frank’s RedHot on the table. Just a few drops—about ½ tsp per serving—adds a tangy spice that balances the creaminess beautifully. Tom always adds extra to his plate.
Parmesan Booster
Extra grated Parmesan on the side lets everyone customize their plate. I use a Microplane to freshly grate about ¼ cup for the table. The sharp, salty flavor enhances the Cheese Whiz sauce without overpowering it.
Pickled Veggies
Tangy pickled jalapeños or banana peppers add a zesty crunch. I add about 2 tbsp per serving for a pop of color and acidity. It’s a trick I learned from my Cincinnati days—Mrs. Henderson always served pickles with rich dishes. ✨
Crushed Red Pepper
A pinch of crushed red pepper flakes—about ¼ tsp—adds subtle heat. Sprinkle it on top or serve on the side for those who like a little spice. It’s an easy way to elevate the dish without extra effort.

Frequently Asked Questions
Can I use a different type of cheese?
Cheese Whiz gives the signature velvety texture, but Velveeta works too. Avoid hard cheeses like cheddar as they won’t melt as smoothly.
How do I prevent the sauce from clumping?
Whisk constantly while adding milk and broth, and keep heat at medium. If lumps form, use a wire whisk to break them up immediately.
Can I make this ahead of time?
Yes! Assemble everything except Parmesan, refrigerate for up to 2 days. Reheat on low with a splash of milk to restore creaminess.
What if my sauce is too thick?
Thin it with warm milk, 1-2 tablespoons at a time, until it coats the pasta smoothly. Avoid water as it dilutes the flavor.
