Ingredients You Need
Pasta and protein
- 12 ounces spaghetti
- Use regular, thin, or whole wheat spaghetti. Avoid very thick pasta, since it needs more sauce.
- 2 cups cooked chicken, shredded or cubed
- Rotisserie chicken saves time and adds great flavor. Leftover grilled or baked chicken also works.
- 1 tablespoon olive oil
- 1 tablespoon butter
- Butter adds richness and helps the sauce coat the pasta.
Veggies and aromatics
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 1 teaspoon Italian seasoning
- 1 teaspoon smoked paprika or sweet paprika
- Smoked paprika adds a subtle smoky note; sweet paprika keeps it mild.
- 1 teaspoon salt, plus more to taste
- ½ teaspoon black pepper
Creamy sauce base
- 2 tablespoons all-purpose flour
- This thickens the sauce. Gluten-free all-purpose blend works as a swap.
- 2 cups low-sodium chicken broth
- Use a good-quality boxed broth; I like Kitchen Basics or Pacific for consistent flavor.
- 1 cup heavy cream
- For a lighter version, use half-and-half, but the sauce turns slightly thinner.
- ½ cup whole milk
- Milk stretches the cream and keeps the sauce silky.
Cheese and finishing touches
- 1 cup freshly grated Parmesan cheese
- Grate it yourself if possible; pre-shredded cheese often clumps and melts less smoothly.
- ½ cup shredded mozzarella
- This gives a stretchy, creamy texture.
- ¼ teaspoon red pepper flakes, optional
- 2 tablespoons chopped fresh parsley or basil for garnish
Pantry shortcuts and substitutions
- Use garlic powder and onion powder if you run out of fresh aromatics. Start with ½ teaspoon each and adjust.
- Use canned chicken in a pinch. Drain it well and season it generously.
- Swap Parmesan with Pecorino Romano for a sharper, saltier flavor.
- Use lactose-free cream and milk if you need a lower-lactose option, and choose a hard cheese that fits your needs.
Equipment list
- Large pot or Dutch oven
- Colander
- Wooden spoon or silicone spatula
- Measuring cups and spoons
- Chef’s knife and cutting board
- Tongs or pasta fork
Tips & Mistakes
- Salt the pasta water generously so the spaghetti tastes seasoned from the inside.
- Cook the spaghetti to just shy of al dente, since it finishes in the sauce and absorbs more liquid.
- Reserve at least 1 cup of pasta water before draining, so you can adjust sauce thickness.
- Sauté the onion until it turns translucent and slightly golden to build deeper flavor.
- Add garlic after the onion softens so it does not burn and turn bitter.
- Sprinkle flour over the butter and aromatics and stir constantly to avoid lumps.
- Pour broth in slowly while you whisk so the sauce stays smooth and creamy.
- Keep the heat at medium or medium-low once you add dairy so the sauce does not curdle.
- Add cheese off the heat or on very low heat so it melts gently and does not clump.
- Taste and adjust salt and pepper at the end, since Parmesan and broth both contain salt.
- Stir the pasta frequently once it sits in the sauce so it does not stick together.
- Avoid overcooking the chicken; add it near the end so it warms through but stays tender.
How to Make Creamy Spaghetti Chicken
Step 1: Boil the spaghetti
Bring a large pot of salted water to a rolling boil. Add the spaghetti and cook until just shy of al dente, usually 1 minute less than the package suggests. Reserve 1 cup of the starchy pasta water, then drain the spaghetti and set it aside.
Step 2: Sauté veggies and aromatics
Heat olive oil and butter in the same pot over medium heat. Add diced onion and cook until soft and lightly golden, about 5 to 7 minutes. Stir in garlic, Italian seasoning, smoked paprika, salt, and black pepper, and cook 1 to 2 minutes until the mixture smells fragrant.
Step 3: Build the creamy base
Sprinkle flour over the onion mixture and stir constantly for 1 minute to cook off the raw flour taste. Slowly pour in the chicken broth while you whisk, breaking up any small lumps. Add heavy cream and milk, then keep stirring until the sauce thickens slightly and coats the back of a spoon.
Step 4: Add cheese and chicken
Lower the heat to medium-low. Stir in Parmesan and mozzarella a handful at a time until they melt into the sauce. Add the shredded chicken and red pepper flakes if you use them, and cook 3 to 4 minutes until the chicken heats through.
Step 5: Combine with spaghetti
Add the cooked spaghetti to the pot with the sauce. Toss gently with tongs until every strand looks coated and glossy. If the sauce feels too thick, splash in a little reserved pasta water until you reach your favorite consistency.
Step 6: Taste and finish
Taste the pasta and adjust salt and pepper as needed. Sprinkle chopped parsley or basil over the top for freshness and color. Let the pasta sit off the heat for 2 to 3 minutes so the sauce thickens slightly and clings to the spaghetti.
Variations I’ve Tried
I swap the chicken with cooked Italian sausage sometimes and add a pinch of fennel seed for a heartier, slightly spicy version. I also stir in a handful of baby spinach or chopped kale at the end, which wilts into the hot sauce and adds a little green to balance the richness. For a veggie-forward twist, I add sautéed mushrooms and peas with the chicken, which gives more texture and sweetness.
I tried a lighter version with half the cream and extra chicken broth, and it still tasted creamy, just less heavy. I also tested a spicy version with extra red pepper flakes and a spoonful of chili crisp, which worked great for heat lovers. If you need a gluten-free option, I use gluten-free spaghetti and a gluten-free flour blend, and it turns out very close to the original.
How to Serve Creamy Spaghetti Chicken
Serve this Creamy Spaghetti Chicken Recipe straight from the pot while it still looks glossy and silky. I like to top each bowl with extra grated Parmesan, a sprinkle of parsley, and a pinch of red pepper flakes for color and a little kick. Pair it with a simple green salad, garlic bread, or steamed broccoli to balance the richness. A cold sparkling water with lemon or iced tea rounds out the meal without feeling heavy.
How to store
- Cool leftovers to room temperature within 1 hour, then transfer them to airtight containers.
- Store in the fridge for up to 3 to 4 days; stir in a splash of milk or broth when you reheat to loosen the sauce.
- Freeze portions in freezer-safe containers for up to 2 months; label with the date so you track freshness.
- Reheat gently on the stove over low heat or in the microwave at 50–70 percent power, adding a bit of milk or broth and stirring often so the sauce turns smooth again.

Ingredients
Instructions
- Cook the spaghetti in a large pot of salted boiling water according to package directions until al dente. Drain and set aside.
- While the pasta cooks, heat the olive oil in a large skillet over medium-high heat. Season the chicken with half of the salt and pepper, then add to the skillet and cook, stirring occasionally, until browned and cooked through, 6 to 8 minutes. Transfer the chicken to a plate and set aside.
- Reduce the heat to medium, add the butter to the same skillet, and let it melt. Add the minced garlic and cook, stirring frequently, until fragrant, about 30 seconds.
- Sprinkle in the flour and cook, whisking constantly, for 1 minute to form a paste.
- Slowly whisk in the chicken broth until smooth, followed by the heavy cream. Bring the mixture to a gentle simmer and cook, whisking often, until slightly thickened, 3 to 5 minutes.
- Stir in the Parmesan cheese, Italian seasoning, remaining salt and pepper, and red pepper flakes if using. Simmer for another 1 to 2 minutes until the sauce is smooth and creamy.
- Return the cooked chicken and any accumulated juices to the skillet, stirring to coat in the sauce. Add the cooked spaghetti and toss until the pasta is well coated and heated through.
- Remove from heat, sprinkle with fresh parsley if desired, and serve the creamy spaghetti chicken immediately.
