Ingredients

• 12 ounces (340 g) spaghetti
• 2 tablespoons olive oil
• 2 boneless, skinless chicken breasts, cut into bite-sized pieces
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon paprika
• 1 teaspoon Italian seasoning
• 1 small onion, diced
• 3 garlic cloves, minced
• 1 small red bell pepper, diced
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cups chicken broth
• 1 cup whole milk
• 4 ounces (115 g) cream cheese, softened
• 1½ cups shredded sharp cheddar cheese
• ¼ cup grated Parmesan cheese
• 2 tablespoons chopped fresh parsley
• Crushed red pepper flakes (optional)

Instructions

1. Cook the Pasta

Bring a large pot of salted water to a boil. Cook the spaghetti until al dente according to the package directions. Reserve ½ cup of the pasta water, then drain and set aside.

2. Cook the Chicken

Heat the olive oil in a large skillet over medium-high heat. Season the chicken with salt, pepper, paprika, and Italian seasoning. Cook for 6–8 minutes, stirring occasionally, until the chicken is golden and fully cooked. Remove from the skillet and set aside.

3. Sauté the Vegetables

Reduce the heat to medium. Add the onion and bell pepper to the same skillet and cook until softened, about 4 minutes. Stir in the garlic and cook for another minute.

4. Prepare the Cream Sauce

Add the butter to the skillet. Once melted, whisk in the flour and cook for 1 minute. Slowly pour in the chicken broth while whisking continuously, followed by the milk.

Bring the sauce to a gentle simmer. Stir in the cream cheese until smooth, then add the cheddar and Parmesan cheeses. Continue stirring until the cheese melts into a silky sauce.

5. Combine Everything

Return the cooked chicken to the skillet. Add the drained spaghetti and gently toss until every strand is coated in the creamy sauce. If needed, stir in a little reserved pasta water to loosen the sauce.

Cook for another 2–3 minutes until everything is heated through.

6. Serve

Sprinkle with fresh parsley and a pinch of crushed red pepper flakes if desired. Serve immediately with garlic bread or a fresh green salad.

Tips for Success

• Cook the spaghetti just until al dente to prevent it from becoming too soft.
• Freshly shredded cheese melts more smoothly than pre-shredded cheese.
• Rotisserie chicken can be used for an even quicker meal.
• Add mushrooms, spinach, or broccoli for extra vegetables.
• Taste the sauce before serving and adjust the seasoning if needed.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently over low heat or in the microwave, adding a splash of milk to restore the creamy consistency.

The dish can also be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating.
