McDonald’s fans in Hong Kong have reason to celebrate: the fast-food giant has unveiled a revamped version of its popular Spicy Chicken Fillet Burger, complete with a larger chicken patty, crisp romaine lettuce, and a lightly sweetened sesame bun. To mark the launch, the chain is offering a three-day introductory price of HK$39 for the set meal from September 14 to 16, 2026, and will surprise 1,000 loyal app users with a complimentary upgrade combo. The promotion aims to reward frequent customers while providing affordable dining options amid rising living costs.
What’s New in the “Upgraded” Spicy Chicken Burger?
The so-called “upgrade” goes beyond a name change. According to McDonald’s Hong Kong, every component has been refined to deliver a more satisfying bite:
- Heartier chicken fillet – A larger, whole-cut chicken thigh fillet is now used, breaded and fried to a golden, crispy crust while retaining juicy, tender meat inside.
- Crisper lettuce – Traditional lettuce has been replaced with fresh romaine lettuce, adding a snappy texture that helps cut through the richness of the fried chicken.
- Slightly sweet sesame bun – The soft bun is topped with sesame seeds, providing a gentle sweetness that balances the spicy kick of the patty.
The upgraded burger is paired with a specially formulated salad dressing, designed to complement the heat and enhance the overall flavour profile.
Three-Day Trial Offer: HK$39 for a Full Set
From September 14 to September 16, 2026, McDonald’s is offering the Upgraded Spicy Chicken Fillet Burger Set Meal for just HK$39. This represents a significant discount compared to the regular menu price, and the company positions the deal as a practical way for budget-conscious consumers to enjoy a filling meal without overspending.
The limited-time offer is available at all participating McDonald’s outlets across Hong Kong, while stocks last. The chain urges customers to order via the McDonald’s App or in-store to secure the promotion.
1,000 Free Meals for the Most Devoted Fans
In a move to thank its most loyal customers, McDonald’s is using its app data to identify the top 1,000 fans of the original Spicy Chicken Fillet Burger over the past 12 months. These selected individuals will automatically receive a coupon for a free Upgraded Spicy Chicken Fillet Burger Set Meal in their McDonald’s App account.
- Selection criteria: The system evaluates purchase history of the original burger via the app from September 2025 to August 2026.
- Coupon distribution: The free meal voucher will be deposited into eligible accounts on September 14 at 11:00 AM.
- Redemption period: Winners can redeem their complimentary set from September 14 to September 16, 2026.
No action is required from customers—the coupon will appear automatically. The promotion is non-transferable and cannot be exchanged for cash.
Why This Matters for Hong Kong Diners
The launch comes at a time when many local consumers are feeling the pinch of inflation and seeking value-for-money meal options. By offering a substantial upgrade—larger portions, better ingredients, and a lower price point—McDonald’s is directly addressing the demand for affordable yet satisfying fast food.
Industry observers note that such limited-time offers also drive app engagement and reward loyalty, a strategy increasingly common among global QSR brands. For the average diner, this is a rare chance to try a significantly improved product at a fraction of the usual cost.
How to Make the Most of the Promotion
To take advantage of the HK$39 offer, simply visit any McDonald’s outlet or order through the app between September 14 and 16. For those hoping to snag a free meal, check your app account on the morning of September 14—if you are among the top 1,000 fans, the voucher will be waiting.
While the upgraded burger is a temporary promotion, its popularity may influence McDonald’s long-term menu decisions. For now, Hong Kong’s fast-food lovers have a narrow window to enjoy a bigger, better Spicy Chicken Burger without breaking the bank.
