Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easier cleanup (optional).
In a mixing bowl, combine the grated Parmesan cheese, minced garlic, olive oil, salt, pepper, and Italian seasoning. Whisk together until well blended.
Pat the chicken breasts dry with paper towels and place them on the prepared baking sheet.
Using a spoon or spatula, spread the garlic Parmesan mixture evenly over the top of each chicken breast, ensuring they are well coated.
Bake the chicken in the preheated oven for 20-25 minutes, or until the internal temperature reaches 165°F (75°C) and the chicken is golden and cooked through.
Remove from the oven and let the chicken rest for 5 minutes before serving. Garnish with chopped parsley if desired.
Adjust the garlic and Parmesan quantities according to your taste preferences.
Serve this dish with a side of vegetables or a salad for a complete meal.
Store leftovers in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.
