In a medium bowl, combine whiskey, soy sauce, Dijon mustard, chopped green onion, chopped basil, ground mustard seed, chicken seasoning, granulated garlic, granulated onion, black pepper, and salt.

Mix all the ingredients together until well combined.

Place steaks in a shallow dish or resealable plastic bag.

Pour the marinade over the steaks, ensuring they are evenly coated.

Cover the dish or seal the bag, and refrigerate for at least 4 hours, or overnight for best flavor.

When ready to cook, remove the steaks from the marinade and discard any excess marinade.

Grill the steaks to your desired level of doneness.
