Step-by-Step Instructions

1. 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 (usually 8–10 minutes).

Before draining, reserve about ½ cup (120 ml) of pasta water. Drain the pasta and set aside.

2. Prepare the Chicken

If your chicken is not already cooked, season it with salt, black pepper, and Italian seasoning. Heat olive oil in a skillet over medium heat and cook the chicken for 6–8 minutes until golden and fully cooked.

Remove from the pan and set aside. Slice or shred into bite-sized pieces.

---

3. Sauté the Onions

In the same skillet, melt the butter over medium heat. Add the thinly sliced onions and cook for 8–10 minutes, stirring occasionally.

Allow them to soften and turn golden brown. This step is crucial—it builds the sweet, savory base of the dish.

Add the minced garlic and cook for another minute until fragrant.

---

4. Make the Cream Sauce

Pour in the heavy cream and milk, stirring to combine. Lower the heat slightly and add the softened cream cheese.

Whisk continuously until the cream cheese melts completely and the sauce becomes smooth. Let it simmer gently for 3–4 minutes until slightly thickened.

---

5. Add Parmesan and Seasoning

Stir in the grated parmesan cheese until fully melted into the sauce.

Season with salt and black pepper to taste. At this stage, the sauce should be creamy, rich, and slightly thick.

---

6. Combine Everything

Add the cooked spaghetti and chicken into the skillet. Toss gently to coat everything evenly in the sauce.

If the sauce feels too thick, add a splash of reserved pasta water to loosen it and create a silky texture.

7. Garnish and Serve

Finish with freshly chopped parsley and a sprinkle of red pepper flakes if desired.

Serve warm with extra parmesan on top.

Frequently Asked Questions

1. Can I make this dish ahead of time?

Yes, this recipe works well for meal prep. You can prepare the entire dish ahead and store it in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of milk or water to loosen the sauce, as it tends to thicken when chilled. Reheat gently over low heat or in the microwave, stirring occasionally to maintain a creamy texture.

---

2. Can I substitute the cream cheese?

If you don’t have cream cheese, you can substitute it with mascarpone or a mixture of heavy cream and a bit more parmesan. However, cream cheese provides a unique tangy richness and thick texture that makes this dish stand out. Greek yogurt can also be used for a lighter option, though it will slightly alter the flavor.

---

3. What type of chicken works best?

Boneless, skinless chicken breast is ideal for this recipe because it’s lean and absorbs the sauce well. However, chicken thighs can also be used if you prefer a juicier and more flavorful option. Rotisserie chicken is a great shortcut and adds extra depth to the dish without additional cooking time.

---

4. How do I prevent the sauce from becoming too thick or clumpy?

The key is controlling heat and stirring properly. Always melt cream cheese over low to medium heat and whisk continuously. If the sauce becomes too thick, add reserved pasta water or milk gradually until you reach the desired consistency. Avoid high heat, as it can cause the dairy to separate.
