Here’s how to prepare Garlic Parmesan Chicken and Potatoes with ease:

1. Preheat the Oven: Begin by preheating your oven to 425°F (220°C).
2. Prepare the Baking Pan: Lightly grease a large baking sheet or casserole dish with olive oil.
3. Season the Chicken: In a large bowl, mix together olive oil, minced garlic, Italian seasoning, salt, and pepper. Add the chicken breasts and toss until well coated.
4. Add the Potatoes: Place the halved baby potatoes into the same bowl, mixing them with the seasoned oil until they’re well coated as well.
5. Arrange in Pan: Transfer the chicken and potatoes to the prepared pan, arranging them in a single layer for even cooking.
6. Sprinkle with Parmesan: Generously sprinkle the grated Parmesan cheese over the chicken and potatoes.
7. Bake: Place the pan in the preheated oven and bake for 35-40 minutes, or until the chicken is cooked through and the potatoes are tender.
8. Broil for Extra Crispiness: If desired, switch the oven to broil for an additional 3-5 minutes, watching closely to achieve a golden crust on the cheese without burning.
9. Garnish: Once cooked, remove the pan from the oven and garnish with fresh parsley, if using.
10. Serve: Allow to cool slightly before serving, ensuring it’s perfect for your plates!

Following these straightforward steps will lead you to a delicious and hearty meal that can be enjoyed by everyone at the table.
