- Pat chicken cutlets dry and season both sides with salt, pepper, and garlic powder. Heat olive oil and 1 tbsp butter in a large oven-safe cast iron skillet over medium-high heat.
- Sear chicken for 3 to 4 minutes per side until golden-brown and cooked to 160°F. Transfer chicken to a clean plate and set aside.
- Reduce heat to medium. Add remaining 1 tbsp butter and sliced onions to the skillet. Cook for 12 to 14 minutes, stirring frequently, until deeply golden and caramelized.
- Add minced garlic and fresh thyme; cook for 1 minute until fragrant. Pour in beef broth and balsamic vinegar, scraping up all browned bits from the pan bottom. Simmer for 3 minutes to reduce.
- Return chicken cutlets to skillet and spoon mounds of caramelized onions over each piece. Top generously with shredded Gruyère and mozzarella cheese.
- Broil under high oven broiler for 3 to 4 minutes until cheese is bubbly and speckled with golden-brown spots. Garnish with fresh thyme and serve hot!
