Imagine twirling tender spaghetti coated in a luxuriously creamy sauce, speckled with juicy chicken and tender veggies, and perfumed with garlic and herbs. Each bite feels warm, satisfying, and totally comforting.
This is the kind of dish you make when the day has been hectic and you still want something that feels special. It comes together quickly, uses simple pantry staples, and makes lovely leftovers for an easy lunch tomorrow.
SaveI first started making this years ago on chaotic school nights, and it quickly became a family favorite. It is also great for potlucks or meal prep because it travels well and keeps well in the fridge.
Chicken Spaghetti Recipe
Ingredients
Main ingredients
Creamy sauce
Optional additions and garnish
Instructions
- Cook the spaghetti
Bring a large pot of salted water to a boil, add the spaghetti, and cook according to package instructions until al dente. Reserve about half a cup of pasta water, then drain and set the pasta aside.
- Brown the chicken
In a large skillet, heat the olive oil or butter over medium heat. Add the chicken pieces, season with salt and pepper, and cook until browned and cooked through, about 5 to 7 minutes. Remove the chicken from the skillet and set aside.
- Sauté aromatics and vegetables
In the same skillet, add the chopped onion and cook until soft and translucent, about 3 minutes. Stir in the minced garlic and broccoli, if using, and cook for another 2 to 3 minutes until fragrant and tender crisp.
- Whisk the sauce base
Sprinkle the flour over the vegetables and stir to coat everything for 1 minute. Slowly pour in the chicken broth while whisking, followed by the heavy cream, dried basil, dried oregano, salt, and pepper. Continue whisking until the mixture is smooth.
- Simmer and thicken
Bring the sauce to a gentle simmer, stirring frequently, and let it bubble until it thickens and lightly coats the back of a spoon, about 3 to 5 minutes. If it seems too thick, whisk in a splash of the reserved pasta water.
- Combine with pasta and chicken
Return the cooked chicken to the skillet, add the drained spaghetti, and toss gently to coat every strand. Adjust the heat to low and add a little more pasta water if you prefer a looser, creamier texture.
- Add the cheeses
Reduce the heat to low, sprinkle the cheddar and mozzarella over the top, and stir until the cheeses are melted and the sauce is smooth and creamy.
- Taste and finish
Season with a pinch more salt and pepper if needed, and brighten the flavors with a squeeze of lemon juice or a sprinkle of chopped parsley. Remove from heat.
- Serve warm and enjoy
Spoon the chicken spaghetti into bowls, top with extra cheese or parsley if desired, and serve immediately while creamy and bubbling.
- Store or reheat leftovers
Cool to room temperature, then refrigerate in an airtight container for up to 3 to 4 days. Reheat gently on the stovetop or in the microwave, adding a splash of milk or broth to restore creaminess.
Substitutions and variations
- Use gluten free spaghetti or zucchini noodles for a gluten free version.
- Swap chicken for cooked rotisserie chicken or canned chicken to save time.
- Use vegetable broth and skip the meat for a vegetarian option.
- Substitute cheddar with Monterey Jack or your favorite melty cheese.
- If you do not have fresh garlic, use 1 teaspoon garlic powder.
Chloe's tips
- Add the broccoli near the end so it stays bright green and tender crisp.
- Reserve pasta water; it helps loosen the sauce and makes reheating smoother.
- Use a good quality cheddar for the best melt and flavor.
- Let the sauce simmer gently so it thickens without scorching.
- Taste and adjust seasoning before serving, especially if using salted broth.
How to store it
- Refrigerate leftovers in an airtight container for up to 3 days.
- Reheat on low in a covered skillet or microwave, adding a splash of milk or chicken broth to refresh the texture.
Serving suggestions
Serve this hearty chicken spaghetti hot, with a little extra cheese and a side salad for a balanced meal.

- Pair with a simple green salad and garlic bread.
