Preheat your oven to 400°F (200°C).
Prepare the chicken by seasoning it with salt and pepper.
In a shallow dish, combine Parmesan cheese and breadcrumbs.
Dip each chicken breast in olive oil, then coat with the Parmesan-breadcrumb mixture.
Place the coated chicken breasts on a baking sheet lined with parchment paper.
Bake the chicken in the preheated oven for 25-30 minutes or until golden and cooked through.
While the chicken is baking, prepare the creamy garlic sauce.
In a saucepan over medium heat, sauté garlic in olive oil until fragrant.
Add heavy cream to the garlic sauté, whisking to combine.
Let the sauce simmer for a few minutes, then stir in the chopped parsley.
Once the chicken is done, remove it from the oven and let it rest for a few minutes.
Serve the chicken with the creamy garlic sauce drizzled on top.
