Start by marinating the chicken breasts in buttermilk for at least 30 minutes.
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a shallow bowl, combine breadcrumbs, grated Parmesan cheese, garlic powder, onion powder, smoked paprika, salt, and pepper.
Remove chicken from the buttermilk, allowing excess to drip off. Dredge each piece into the flour, shaking off the excess, then dip into the breadcrumb mixture, pressing firmly to adhere.
Heat the olive oil in a large oven-safe skillet over medium-high heat. When hot, add the coated chicken breasts and cook for 3-4 minutes on each side until golden brown.
Transfer the skillet to the preheated oven and bake for an additional 15-20 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and is crispy.
In a small saucepan on medium heat, add a bit more olive oil and sauté minced garlic until fragrant, about 1-2 minutes. Remove from heat and stir in lemon juice.
Drizzle the garlic sauce over crispy Parmesan chicken and garnish with chopped fresh parsley.
Notes
Serve the chicken on a large platter with an extra drizzle of garlic sauce, and garnish with lemon wedges and fresh parsley for a pop of color.
