Creating your own Crispy Rosemary Chicken and Fries can be both fun and fulfilling. Simply follow these steps to achieve delicious results:

1. Preheat the Oven: Preheat your oven to 425°F (220°C). This high temperature is key for achieving the desired crispiness.
2. Prepare the Chicken: In a large bowl, combine olive oil, chopped rosemary, minced garlic, salt, black pepper, paprika, and onion powder. Add the chicken thighs and coat them well with the marinade. Let them sit for at least 15 minutes to absorb the flavors.
3. Cut the Potatoes: While the chicken marinates, cut the russet potatoes into even-sized fries. This will ensure they cook evenly.
4. Season the Fries: In a separate bowl, toss the potato fries in olive oil, salt, and pepper until nicely coated.
5. Arrange on Baking Sheet: Place the marinated chicken and seasoned fries on a large baking sheet, ensuring they are not overcrowded. This helps in achieving crispiness.
6. Bake: Place the baking sheet in the preheated oven and bake for 30-40 minutes, or until the chicken skin is crispy and the internal temperature reaches 165°F (75°C).
7. Flip Halfway: After about 20 minutes, turn the fries and chicken to promote even cooking.
8. Cool Slightly: Once done, remove from the oven and let rest for 5-10 minutes. This helps the juices in the chicken redistribute and keep the meat tender.
9. Garnish: For an extra pop of flavor, sprinkle freshly chopped rosemary over the chicken and fries before serving.

With these simple steps, you will have successfully crafted a delicious meal that highlights the wonderful flavors of the ingredients used.
