01 - Preheat the oven to 425°F for roasting the potatoes.
02 - In a bowl, toss halved potatoes with olive oil, salt, pepper, rosemary, and minced garlic. Spread evenly on a baking sheet, cut side down.
03 - Roast potatoes for 35–40 minutes, flipping halfway through, until golden and crispy.
04 - Combine olive oil, paprika, garlic powder, oregano, salt, pepper, and lemon juice in a bowl. Add chicken breasts and coat thoroughly. Let marinate for at least 10 minutes.
05 - Preheat a grill or grill pan over medium-high heat. Grill chicken breasts for 5–6 minutes per side, or until internal temperature reaches 165°F.
06 - Remove chicken from heat and let rest for 5 minutes before slicing to retain juices.
07 - Serve grilled chicken alongside crispy roasted potatoes. Garnish with chopped fresh parsley and lemon wedges.
