Popeyes’ Spicy Chicken Sandwich
Popeyes shook up the fast food world in 2019 with this sandwich, causing lines around the block and fiery arguments online. Their buttermilk-battered chicken, marinated in Louisiana spices, rests on a brioche bun with crispy pickles and spicy mayo.

McDonald’s Spicy McCrispy
McDonald’s was quick to respond with the Spicy McCrispy, a crispy chicken breast spiced up with pepper sauce and crinkle-cut pickles on a potato roll.

Others enjoy its fresh chicken and budget-friendly price. It’s a polarizing choice, but it’s doing enough for anyone seeking a straightforward, value-priced spicy option.

KFC brings its fried chicken know-how with a double-breaded, crispy breast seasoned with a Kentucky-style spice mix. Spicy mayo and thick pickles on a brioche bun add to the hefty package.

Jack in the Box attempted to cause a splash in 2020 with this one: a hearty chicken filet coated with spicy breading, pickles, and a mustard-flavored mystery sauce on a brioche bun.
