Jack in the Box Just Launched New Sliders: Here’s Everything You Need to Know
Jack in the Box is officially turning 75 in 2026, and the San Diego-based chain is celebrating with a major menu overhaul that blends high-tech innovation with heavy nostalgia. While much of the year's focus has been on the return of “legacy” items, the real breakout star of the spring season is a brand-new platform: the Smashed Jack Sliders.
This move signals a strategic shift for the brand as it attempts to bounce back from a challenging 2025 by “getting back to the basics” while still appealing to the younger, trend-focused Gen Z and Millennial demographics.
The Debut of Smashed Jack Sliders
The headline for late March 2026 is the nationwide rollout of Smashed Jack Sliders. These aren't your typical fast-food sliders; they feature a “smashed” beef patty technique that creates crispy, caramelized edges while maintaining a juicy center.
This “craft-style” approach mimics the popular smashburger trend seen in high-end casual dining. By shrinking this premium format into a slider, Jack in the Box is targeting the “snackable” market, offering a high-quality protein option that feels more elevated than a standard value-menu cheeseburger.
75th Anniversary “Legacy” Returns
To complement the new sliders, Jack in the Box is bringing back a rotating cast of fan favorites throughout 2026. This March saw the return of the Chicken Supreme, a fried chicken patty topped with a signature mayo-onion sauce and melted Swiss-style cheese on a cracked-wheat bun.
Also rejoining the lineup are Frings the legendary side that combines french fries and onion rings in a single container. These returns are designed to evoke nostalgia among long-time fans while the newer items, like the sliders, draw in a fresh audience.
The Oreo Matcha Shake Pairing
Innovation in the beverage department is keeping pace with the new food releases, specifically through the launch of the Oreo Matcha Shake. This limited-time 2026 offering combines a creamy vanilla shake base with earthy matcha powder and crunchy Oreo cookie pieces.
While matcha can be polarizing, early customer reviews suggest the sweetness of the Oreo helps balance the green tea's bitterness, making it an accessible “entry-level” matcha drink. It is being marketed as the perfect “cool-down” pairing for the salty, savory Smashed Jack Sliders.
Availability and Pricing
The Smashed Jack Sliders and the 75th-anniversary items are currently available at participating locations across the 25 states where Jack in the Box operates. To drive engagement, the brand is offering many of these new items via the Jack Pack loyalty app first, often with “2 for $5” slider deals or discounted “Munchie Meal” upgrades.
As part of the 75-year celebration, keep an eye out for special “Throwback Thursday” pricing throughout April, where legacy items may be offered at a significant discount to reward loyal app users.
