Using a kitchen mallet, pound each chicken breast to an even thickness.
In a small bowl, combine sriracha, garlic, salt, and black pepper.
Coat both sides of the chicken with this mixture, cover, and set aside for 15 minutes.
In a large skillet, heat 1-2 tablespoons oil over medium-high heat.
Add the chicken and cook for 4 minutes, flip the chicken and cook for an additional 4 minutes. If needed, add a bit of chicken broth or a small amount of water to the pan.
Turn off the stove, cover the chicken, and allow it to rest for 5 minutes. Ensure that the internal temperature of the chicken is 165 degrees Fahrenheit before serving.
