Thoroughly pat chicken cutlets completely dry with paper towels on both sides. A dry surface ensures an ultra-crisp golden sear.
In a shallow dish, whisk together the flour, garlic powder, onion powder, oregano, thyme, sea salt, and black pepper. Lightly dredge each cutlet, tapping off excess so only a sheer dusting remains.
Heat olive oil and 1 tablespoon of butter in a large skillet over medium-high heat until shimmering hot.
Add the chicken cutlets in a single layer. Sear undisturbed for 3 to 4 minutes until golden-brown and crispy on the bottom.
Flip cutlets, reduce heat to medium, and sear for 3 minutes on the second side until cooked through (165°F / 74°C). Transfer to a warm plate and set aside.
Add remaining 2 tablespoons of butter and minced garlic to skillet, cooking for 30 seconds until fragrant. Pour in chicken broth and lemon juice, scraping up caramelized browned bits from the pan floor.
Simmer sauce for 2 minutes until glossy and reduced. Return cutlets and lemon wheels to pan, turn once to coat in sauce, garnish with parsley, and serve hot!
