- Bring a large pot of salted water to a boil. Add 12 oz of penne pasta and cook according to package instructions until al dente. Drain the pasta and set aside. Toss the drained pasta with a tablespoon of olive oil to keep it from sticking. 
- Heat a skillet over medium heat and cook the chicken breasts seasoned with salt and pepper until cooked through, about 6-8 minutes per side. Let them rest before shredding with forks. If you prefer, use pre-cooked rotisserie chicken for a shortcut. 
- In the same skillet, cook 1/2 cup of turkey bacon until crispy. Remove and crumble once cooled. This adds a smoky, savory layer to the bake but can be omitted for a lighter version. 
- In a medium bowl, combine 1 cup softened cream cheese, 1 cup sour cream, 1 teaspoon garlic powder, 1 teaspoon onion powder, salt, and pepper. Stir until smooth. Fold in the thawed and drained spinach along with the chopped artichoke hearts. 
- Preheat your oven to 350°F (175°C). In a large mixing bowl, combine the cooked pasta, shredded chicken, creamy spinach-artichoke sauce, and half of the shredded mozzarella and grated parmesan cheeses. Mix gently until everything is evenly coated. 
- Transfer the mixture to a greased 9x13-inch baking dish. Sprinkle the remaining mozzarella and parmesan cheese evenly on top. Add the crumbled turkey bacon if using. Bake uncovered for 25-30 minutes or until the cheese is bubbly and golden brown on top. 
- Once baked, let the pasta cool slightly before serving. This Spinach & Artichoke Chicken Pasta Bake pairs beautifully with a simple green salad or crusty bread for a complete meal.
