1. Prepare the Potatoes

Begin by preparing the potatoes. If using baby potatoes, halve them or leave them whole if they’re small. If using larger potatoes, cut them into cubes. The key is to ensure the potato pieces are roughly the same size so they cook evenly.

Place the potatoes in a bowl and drizzle them with olive oil. Toss them well to coat evenly. Season with salt, black pepper, and garlic powder to taste. Set the potatoes aside while you prepare the chicken.

2. Season the Chicken

Season the chicken thighs with salt and pepper on both sides. If you’re using chicken breasts, you can use the same method. For extra flavor, feel free to rub the chicken with garlic powder, onion powder, or your favorite seasoning mix.

This seasoning will create a flavorful crust as the chicken roasts, enhancing the overall flavor of the dish.

3. Prepare the Garlic Parmesan Sauce

In a separate bowl, combine the melted butter, Parmesan cheese, garlic powder, onion powder, Italian seasoning, and crushed red pepper flakes (if using). Whisk everything together until the sauce is smooth and well combined. Taste the sauce and adjust the seasoning with salt and pepper to your liking. This sauce is what will give the chicken and potatoes their delicious, savory coating.

4. Roast the Potatoes

Preheat your oven to 400°F (200°C). In a large oven-safe skillet or baking dish, arrange the seasoned potatoes in a single layer. Roast the potatoes in the preheated oven for 20-25 minutes, or until they begin to soften and turn golden brown on the edges. You can stir the potatoes halfway through to ensure they cook evenly.

While the potatoes are roasting, the garlic Parmesan sauce can be set aside, ready to coat the chicken and potatoes later.

5. Sear the Chicken

While the potatoes are roasting, heat a tablespoon of olive oil in a large skillet over medium-high heat. Once the oil is hot, add the chicken thighs (skin side down) to the skillet. Sear the chicken for about 5-6 minutes on each side, until the skin is crispy and golden brown. This step is optional, but it helps to lock in the juices and adds extra flavor to the chicken.

Once the chicken is seared, remove it from the skillet and set it aside.

6. Combine the Chicken and Potatoes

Once the potatoes are partially roasted, take the skillet out of the oven and add the seared chicken thighs on top of the potatoes. Spoon some of the garlic Parmesan sauce over each piece of chicken, making sure to coat it generously. If there is extra sauce, you can drizzle it over the potatoes as well.

Return the skillet to the oven and continue roasting for another 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the potatoes are crispy and tender. The sauce will bubble and create a golden crust on both the chicken and the potatoes.

7. Garnish and Serve

Once the chicken and potatoes are fully cooked, remove the skillet from the oven. Garnish with freshly chopped parsley and a squeeze of lemon juice, if desired. This adds a fresh, zesty note that balances the richness of the garlic Parmesan sauce.

Serve the Garlic Parmesan Chicken and Potatoes immediately, and enjoy the perfect combination of crispy potatoes, juicy chicken, and savory sauce.
