Absolutely! When it comes to fajita chicken, cutting it before cooking can be a fantastic idea. Slicing the chicken into thin strips allows it to cook more rapidly and evenly. Plus, when the chicken is in smaller pieces, it tends to absorb the flavors of the marinade or seasoning more effectively. So, if you're aiming for maximum flavor infusion, cutting the chicken before cooking is a great approach. However, if you're seeking a different culinary experience, you can also choose to cook the chicken whole or in larger pieces. This method has its perks too! By keeping the chicken intact during cooking, you can preserve its natural juiciness and tenderness. You can then slice it afterward to the desired thickness. This approach allows you to have more control over the level of doneness and retain the succulence of the chicken. Ultimately, it all depends on your preferences and the specific outcome you're looking to achieve in your fajitas.
