Bring a large pot of salted water to a boil and cook the pasta until al dente. Drain and set aside.
In a large skillet over medium heat, cook the bacon until crispy. Remove, crumble, and set aside. Leave about 1 tablespoon of bacon grease in the pan.
Add butter to the skillet. Once melted, add garlic and sauté for 20–30 seconds until fragrant.
Pour in the heavy cream and reduce heat to low. Let the cream warm gently without boiling.
Slowly stir in the grated Parmesan cheese until the sauce becomes smooth and creamy.
Add the cooked chicken to the sauce and stir until evenly coated.
Add the cooked pasta and crumbled bacon, tossing gently until everything is well combined.
Season with salt and black pepper to taste. Serve immediately.
