Place the chicken into a large resealable bag or container.
Whisk together the lemon juice, Worcestershire, steak sauce and butter.
Pour the marinade over the chicken.
Cover and refrigerate for 2-4 hours, turning the chicken every 30 minutes.
When ready to cook, fire up your Big Easy.
Remove the chicken from the marinade and shake off any excess.
Season the chicken liberally with salt and pepper and transfer to the Big Easy basket.
Cook until the chicken measures 165 F as measured in several places, generally 20 minutes per pound.
Let rest for 10 minutes before serving.
