Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius). Lightly grease a baking dish or line it with parchment paper.
Pat the chicken breasts dry with paper towels. This helps the topping adhere better.
In a small bowl, mix the Caesar dressing and mayonnaise (or Greek yogurt) together until combined. This mixture acts as a binder to keep the chicken moist.
In a separate shallow dish, combine the grated Parmesan cheese, panko breadcrumbs, Caesar seasoning mix, salt, and pepper. Mix well.
Dip each chicken breast first into the dressing mixture, coating both sides lightly.
Press the coated chicken firmly into the Parmesan breadcrumb mixture, ensuring the top surface is completely covered with the topping.
Place the coated chicken breasts in the prepared baking dish.
Bake for 20 to 25 minutes, or until the internal temperature reaches 165 degrees Fahrenheit (74 degrees Celsius) and the topping is golden brown and crispy.
Let the chicken rest for 5 minutes before serving.
Notes
For extra moisture, you can lightly pound the thickest part of the chicken breasts to an even thickness before coating.
If the topping starts browning too quickly before the chicken is done, loosely tent the dish with aluminum foil for the last 5-7 minutes of baking.
Serve this chicken with a simple green salad tossed with extra Caesar dressing or alongside cooked pasta tossed with butter and garlic.
