What is the Chicken Sunday at Shake Shack
The Chicken Sunday is a signature sandwich at Shake Shack, featuring a butter-steamed brioche bun, double chicken breast filets, lettuce, tomato, and Shack Sauce. It is designed as a milder, butter-rich alternative to the ShackBurger and is positioned as a shareable, premium chicken sandwich rather than a spicy or Korean-inspired item.
Key ingredients and flavor profile
The Chicken Sunday highlights tender chicken breast, juicy tomato, crisp lettuce, and a savory-sweet Shack Sauce, all held together by a soft brioche bun toasted in rendered beef tallow. The dish is intentionally less spicy than Korean fried chicken offerings and focuses on richness, texture contrast, and a balanced, approachable flavor profile.
Core components
- Double chicken breast filets
- Butter-steamed brioche bun
- Shack Sauce (sweet, tangy, mayo-based)
- Lettuce and tomato
- Beef tallow for toasting
How it compares to the ShackBurger
While the ShackBurger is the brand’s classic beef-centric sandwich, the Chicken Sunday offers a poultry-focused option with a richer, buttery bun. Both share Shack Sauce and fresh produce, but the Chicken Sunday uses chicken instead of beef and a brioche bun instead of a potato roll, creating a different texture and flavor balance.
Quick comparison
| Attribute | Chicken Sunday | ShackBurger |
|---|---|---|
| Primary protein | Chicken breast | Beef patty |
| Bun style | Butter-stepped brioche | Potato roll |
| Flavor focus | Rich, buttery, sweet | Savory, charred, beef-forward |
| Typical price range | Higher than a single ShackBurger | Baseline for comparison |
Price, sizes, and availability
Prices vary by location and market conditions, and the Chicken Sunday is usually priced above a single ShackBurger due to higher protein and bun costs. It is available in most North American and select international locations year-round, though limited-time sides or bundle offers may vary by market.
Pairing recommendations and customization
The Chicken Sunday pairs well with crinkle-cut fries, a side salad, or a frozen custard dessert. Customers can request modifications such as extra sauce, grilled onions, or a different bun style where feasible, though the butter-steamed brioche is a core part of the sandwich’s identity and changing it may alter the intended texture and richness.
