1. Prepare the Oven and Baking Sheet: Setting the Stage for Roasting

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Line Baking Sheet: Line a large baking sheet with parchment paper for easy cleanup. Alternatively, you can lightly grease the baking sheet.

2. Prepare the Chicken: Seasoning for Flavor

1. Pat Dry: Pat the chicken breasts dry with paper towels. This helps the seasonings adhere better.
2. Combine Seasonings: In a small bowl, whisk together the Italian seasoning, smoked paprika, salt, and black pepper.
3. Coat Chicken: Drizzle the chicken breasts with 1 tablespoon of olive oil, then rub the seasoning mixture evenly over both sides of each chicken breast.

3. Prepare the Potatoes: Coating for Crispiness and Flavor

1. Halve Potatoes: Wash and halve the baby Yukon Gold or red potatoes.
2. Toss with Oil and Seasonings: In a large bowl, toss the halved potatoes with 3 tablespoons of olive oil, minced garlic, grated Parmesan cheese, salt, and pepper. Ensure the potatoes are evenly coated.

4. Assemble on the Pan: Creating a One-Pan Meal

1. Arrange Chicken: Place the seasoned chicken breasts on one side of the prepared baking sheet.
2. Spread Potatoes: Spread the seasoned potatoes evenly on the other side of the baking sheet, making sure they are in a single layer for even cooking.

5. Bake to Perfection: Achieving Golden-Brown and Tender Results

1. Roast: Place the baking sheet in the preheated oven. Roast for 25-30 minutes.
2. Flip Potatoes: Flip the potatoes halfway through the cooking time to ensure they brown evenly on all sides.
3. Check for Doneness:
   • Chicken: The chicken is done when it reaches an internal temperature of 165°F (74°C) when tested with a meat thermometer. The juices should run clear, and the meat should no longer be pink.
   • Potatoes: The potatoes should be golden brown and crispy on the outside and tender on the inside. You can test them by piercing them with a fork – it should slide in easily.

6. Optional Finishing Touch: Adding Extra Flavor and Texture

1. Add Parmesan (Optional): In the last 5 minutes of cooking, sprinkle some extra grated Parmesan cheese over the chicken and potatoes.
2. Broil (Optional): If desired, turn on the broiler for the last 2-3 minutes of cooking to create a golden-brown crust on the cheese and chicken. Watch it closely to prevent burning.

7. Garnish and Serve: The Final Touches

1. Garnish: Remove the baking sheet from the oven and garnish the dish with freshly chopped parsley, if desired.
2. Serve Hot: Serve the Garlic Parmesan Chicken and Potatoes hot, directly from the baking sheet or portioned onto plates.
