Ingredients
  

Pasta and Chicken

  • 12 ounces penne pasta Use oil-packed sun-dried tomatoes for richer flavor.
  • 1 pound boneless, skinless chicken breasts, cut into bite-sized pieces Can use pre-cooked rotisserie chicken (torn) to reduce skillet time.

Sauce Ingredients

  • 3 tablespoons unsalted butter Reduce to 2 tbsp for a lighter version.
  • 3 cloves garlic, minced
  • 3 tablespoons all-purpose flour Equal parts fat and flour gives stable thickening.
  • 2 cups chicken broth Reserve a little pasta water to loosen the sauce if needed.
  • 1 cup heavy cream Use half-and-half for a lighter version.
  • 1 cup grated Parmesan cheese, divided Reserve some for topping.
  • 1 teaspoon Italian seasoning
  • 1/2 cup sun-dried tomatoes, drained and chopped Rinse and chop if using oil-packed.
  • 3 cups fresh spinach

Toppings

  • 1 1/2 cups shredded mozzarella cheese For topping.
  • 1/4 cup grated Parmesan cheese For topping.

Instructions
 

Preparation

  • Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
  • Bring a large pot of salted water to a boil. Cook the penne for 1–2 minutes less than package directions so it’s just al dente. Drain and set aside.
  • In a large skillet over medium heat, heat 1 tablespoon olive oil. Season chicken with 1/2 tsp salt, 1/4 tsp pepper, and 1/2 tsp garlic powder. Cook the chicken for 5–6 minutes, stirring occasionally, until golden and cooked through.

Making the Sauce

  • In the same skillet, melt 3 tablespoons of butter over medium heat. Add minced garlic and cook until fragrant.
  • Stir in 3 tablespoons of flour and cook for 1 minute to form a roux.
  • Slowly whisk in 2 cups of chicken broth followed by 1 cup of heavy cream. Bring to a gentle simmer and cook for 3–4 minutes until the sauce thickens.
  • Remove from heat and stir in 1 cup of grated Parmesan, Italian seasoning, chopped sun-dried tomatoes, and fresh spinach. Stir until the spinach wilts.

Assembly and Baking

  • Add the drained pasta and cooked chicken to the sauce. Toss gently to coat.
  • Transfer mixture to the prepared baking dish. Sprinkle with mozzarella and additional Parmesan.
  • Bake uncovered for 20–25 minutes until bubbly and golden. Let rest for 5 minutes before serving.

Notes

Best served with a crisp green salad and crusty bread. A light lemon-arugula salad cuts the dish’s richness nicely.
