The fillet’s lack of heat is really noticeable with the Spicy Cluck Sandwich. The regular Good Good Sauce dampens the breading’s spiciness enough that you might think you’re eating an original Cluck Sandwich.
Jack in the Box’s Spicy Cluck Sandwich features a crispy-fried spicy chicken filet, Jack’s Good Good Sauce, and pickle chips on a toasted brioche bun. I went and bought one for $5.79.
The new Cluck Sandwich is available on its own or as part of a new Cluck Sandwich Combo, served with a side of fries and drink. It’s notable that the Deluxe Cluck doesn’t come with mystery sauce.
So I’m probably not going to solve what the Mystery Sauce is in Jack in the Box’s new Cluck Sandwich. It features Jack’s new thicker and crispier 100% all-white meat fried chicken fillet, pickles, and the chain’s Mystery Sauce on a toasted brioche-style bun.
