Step 1: Preheat the Oven

1. Preheat your oven to 400°F (200°C). Line a baking dish with parchment paper or lightly grease it with cooking spray to prevent sticking.

Step 2: Prepare the Chicken

1. Pat the chicken dry with paper towels to help the seasoning stick better. Place the chicken breasts or thighs in the prepared baking dish in a single layer.

Step 3: Season the Chicken

1. Drizzle olive oil or melted butter over the chicken, ensuring each piece is evenly coated.
2. In a small bowl, combine the ranch seasoning mix, garlic powder, onion powder, paprika (if using), salt, and black pepper. Sprinkle the seasoning mixture evenly over both sides of the chicken.

Step 4: Bake the Chicken

1. Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes.
2. Remove the foil and continue baking for another 10-15 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) in the thickest part.

Step 5: Add Optional Toppings

1. If desired, sprinkle shredded cheddar cheese over the chicken during the last 5 minutes of baking. Let it melt and bubble for a cheesy finish.

Step 6: Rest and Serve

1. Remove the chicken from the oven and let it rest for 5 minutes before serving. Garnish with fresh parsley or chives, if desired, for a pop of color and freshness.
