Back in 1995, Wendy’s introduced a spicy chicken sandwich to the menu, way before the latest wave hit menus over the last few years.
“There was a lot of fandom out there for this sandwich so giving it an update was a bit of a challenge,” said Becky Davis, VP of global culinary innovation for the Dublin, Ohio-based fast-food chain. “But we’re always listening to consumers, and we started hearing that they were looking for a boost in flavor and quality. So we took that to heart and started a robust testing process to make sure we were delivering on those expectations.”
Davis and her team started “tinkering in the kitchen,” and it took over a year and a dozen iterations to fully develop and test the sandwich to meet today’s tastes. The new Spicy Chicken Sandwich made its official debut at the at the end of March. Here’s the story behind its glow-up.
Starting from the top down
The bun was the first component to get an upgrade.
“We heard guests were looking for a bun with more of a premium flavor and texture, so we gave it a full overhaul,” said Davis. “We now source a new potato bun that has a little bit of sweetness to it. It's a soft, indulgent, craveable, premium bun but still has the structural integrity to hold up to all our crispy chicken sandwiches and hot and juicy hamburgers.” The goal was to use the bun across all Wendy’s premium sandwiches, and the team realized that goal.
The potato bun was a big change for the more than 5,500 Wendy’s locations in the U.S., said Davis. It replaced a sturdier brioche-style bun.
The mayo was the next ingredient to be swapped out. “We went for a richer, Southern-style mayonnaise that gives you a creamy mouthfeel that’s very indulgent,” she added. The lettuce and tomato in the previous build stayed the same, and pickles were added on top. But the star of the sandwich—the crispy, spicy chicken filet—was treated to a flavor and texture makeover.
Davis recalled, “when we started innovating this, we asked ourselves, ‘How much does it have to change? Do we give it a complete overhaul and start from scratch to build something new?’”
Ultimately, consumers revealed that they liked the OG spicy chicken sandwich, but they wanted more of it—more flavor, more heat, more crunch and more juiciness. “We were able to start in a great spot and build upon it,” said Davis.
The culinary team brought in some new peppers and started playing with the spice level. Chipotles, she explained, provide smokiness along with heat, and anchos have sweet notes. Both were used in the chicken marinade and the breading to drive up flavor as well as heat. “Being able to apply heat and flavor at different points in the marinade and breading system is really important,” she said.
The size of the boneless, skinless chicken breast filet is roughly the same as before, and the marinade imparts more flavor and juiciness.
But the breading system has been completely updated. Instead of fine breadcrumbs, Wendy’s now uses a panko-style breading that is fluffier and delivers more height and crunch when fried.
Texture got as much attention as flavor from the R&D team. “It's almost like you want to be able to bite into the chicken sandwich and hear it from the other side of the room, and have someone go ‘Oh my gosh, what are you eating? That sounds delicious, and I want one of those,’” said Davis. “I think this sandwich really hits that mark.”
Although Wendy’s couldn’t get into the proprietary cooking technology, Davis did share that it was key to balance the temperature of the oil and the frying time to achieve optimum crispiness and juiciness. Sometimes those two characteristics almost go against each other, she said.
Testing and more testing
When Wendy’s heard from consumers that they should make the Spicy Chicken Sandwich spicier, the team accepted the challenge. But when some of the spicy versions were tasted internally, they might have been a bit over the top. “I can't say exactly how far we pushed it, but I can say that I definitely know how spicy is too spicy for consumers,” said Davis.
Wendy’s recently launched a line of sauces in dip cups. Guests can tailor the sandwich’s spice to their taste buds, taming it by layering on a new buttermilk ranch or dialing it up with Scorchin’ Hot sauce. The brand’s regular Crispy Chicken Sandwich was treated to the same breading, bun and mayo upgrades and is a available for guests who prefer a milder version.
All the product development was done side by side with Wendy’s suppliers and testing with consumers every step of the way. Groups were brought into the Dublin headquarters to taste test and provide feedback, sharing what they liked and what they would change with every tweak that was made.
Once the sandwich was finalized, “we wanted to make sure that it worked in a real-world scenario, in our restaurants, with fans that were actually buying the menu item,” said Davis. “So a full year in [Fall, 2025] we took this down to locations in West Palm Beach, Las Vegas and Orlando, tested it with consumers, got their feedback in the restaurants and that ultimately led to where we are today.”
The new and improved Spicy Chicken Sandwich is now a permanent menu item systemwide. Franchisees set prices, but it’s selling for about $5.89-$6.79, depending on location.
What’s next
Wendy's releases its Spring menu Monday, once again turning up the heat with some spicy limited-time additions. There's a Jalapeño Ranch Cheeseburger with creamy jalapeño ranch, jalapeño slices and American cheese, Jalapeño Bacon Breakfast Potatoes with Swiss cheese sauce, and Jalapeño Breakfast Biscuit sandwiches.
Spring's Frosty Fusion is swirled with cookie dough pieces and brownie batter.
On the sweet side, a Cookie Dough Frosty Fusion is making its debut, along with three watermelon drinks: lemonade, sparkling energy and watermelon-infused Sprite.
Although she won’t give away any secrets for summer and fall launches, Davis is always innovating on Wendy’s signature menu items: burgers, chicken, fries, the Frosty and Frosty Fusions.
“We’re not going to be the brand that is trying to chase a trend overnight to win over a consumer for a day,” she said. “It’s important for brands to understand who they are and continue to honor their legacy.”
