Expert Tips for Perfect Chicken Parmesan
Chicken Preparation: Pound chicken breasts to even thickness for consistent cooking. This ensures every bite is perfectly tender.
Cheese Selection: Use a combination of low-moisture mozzarella for perfect melting and quality parmesan for authentic flavor.
Sauce Matters: Choose a high-quality marinara sauce with simple ingredients for the best results. You can make your own or use a trusted brand.
Don’t Skip the Sear: Searing the chicken first adds incredible flavor and texture that baking alone can’t achieve.
