Preheat your oven to 375°F (190°C).
Thinly slice the chicken breasts if you haven’t done so already.
In a mixing bowl, combine the softened cream cheese, shredded cheddar cheese, shredded Monterey Jack cheese, mayonnaise, pressed garlic, salt, and pepper. Mix until well combined and creamy.
In your baking dish, lay the thinly sliced chicken breasts in a single layer.
Spread the cheesy mixture generously over the chicken breasts.
Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until cooked through and cheese is bubbly.
Garnish with chopped green onions and parsley before serving.
