Step 1: Preheat the Oven

1. Preheat your oven to 375°F (190°C). Grease a baking dish with nonstick spray or a light coating of olive oil to prevent sticking.

Step 2: Prepare the Chicken

1. Pat the chicken breasts dry with paper towels to remove excess moisture.
2. Rub each piece of chicken with olive oil, ensuring an even coating on all sides.

Step 3: Season the Chicken

1. In a small bowl, mix the ranch seasoning, garlic powder, smoked paprika, and black pepper.
2. Sprinkle the seasoning mixture evenly over both sides of the chicken, pressing gently to adhere.

Step 4: Arrange and Bake

1. Place the seasoned chicken breasts in the prepared baking dish in a single layer.
2. Bake in the preheated oven for 25-30 minutes, or until the internal temperature of the chicken reaches 165°F (74°C). For even cooking, check the chicken halfway through and rotate the baking dish if necessary.

Step 5: Add Optional Topping

1. If desired, sprinkle shredded cheese over the chicken during the last 5 minutes of baking. Allow it to melt and create a gooey, flavorful topping.

Step 6: Rest and Serve

1. Remove the chicken from the oven and let it rest for 5 minutes to retain its juices.
2. Garnish with fresh parsley and serve immediately with your choice of sides.
