Bring a large pot of salted water to a boil. Add the 8 oz penne pasta and cook according to package instructions until al dente, about 10-11 minutes. Drain and set aside.
Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Cook diced chicken breast until no longer pink and starting to brown, about 6-7 minutes. Remove and set aside.
In the same skillet, cook chopped turkey bacon until crispy, about 4 minutes. Remove and set aside with chicken.
Reduce heat to medium. Add chopped onion and sauté until soft and translucent, about 3-4 minutes. Add minced garlic and cook 1 minute until fragrant.
Lower heat and pour in 1 cup heavy cream. Stir in grated Parmesan cheese, black pepper, salt, and dried Italian herbs. Stir continuously until cheese melts and sauce thickens slightly, about 3-4 minutes. Adjust seasoning to taste.
Return chicken and turkey bacon to skillet. Add drained penne pasta and gently toss to coat with creamy sauce.
Preheat oven to 375°F (190°C). Pour pasta mixture into greased 9x13 inch baking dish. Sprinkle shredded mozzarella cheese evenly over the top.
Bake uncovered for 20-25 minutes, until cheese is melted, bubbly, and golden on top.
Remove from oven and let rest for 5 minutes. Garnish with freshly chopped parsley. Serve warm and enjoy.
