Pound chicken breasts to uniform thickness (about ¾ inch) before cooking to ensure even cooking and prevent dry edges while the center finishes cooking.

Bloom the taco seasoning in a bit of oil for 30 seconds before adding chicken to unlock deeper spice flavors and create a more complex taste profile.

Use a chunky or medium salsa rather than smooth to add texture and prevent the sauce from becoming too thin, and consider draining excess liquid to maintain proper consistency.

Add shredded cheddar cheese in the final 2-3 minutes of cooking and cover to allow it to melt evenly without separating or becoming oily.

Let the cooked salsa chicken rest for 5 minutes under loose foil before serving to allow juices to redistribute, keeping the meat tender and flavorful throughout.
