Cook the Pasta: Bring a large pot of salted water to a rolling boil. Carefully add the penne pasta and cook according to package directions until al dente, usually about 9-11 minutes. Once cooked, drain the pasta in a colander and set it aside.

Sauté Chicken: In a spacious skillet, heat 2 tablespoons of olive oil over medium heat. Add diced chicken breast to the pan, cooking for about 5-7 minutes until browned and no longer pink inside.

Add Garlic and Spinach: Stir in 2 minced garlic cloves, allowing them to sauté for about 30 seconds until fragrant. Then, add 4 cups of fresh spinach, cooking for an additional 2-3 minutes until it's wilted.

Make the Sauce: Pour in 1 cup of heavy cream into the skillet, stirring to combine everything smoothly. Let the mixture simmer over low heat for about 2-3 minutes until the sauce thickens slightly.

Combine Ingredients: Add the cooked penne pasta to the skillet, using tongs to gently toss everything together.

Finish with Cheese: Stir in ½ cup of grated Parmesan cheese, mixing until it's melted and creamy throughout the dish.

Serve Hot: Plate the creamy Chicken Spinach Penne in generous servings and serve immediately while hot.
