When Does the Shamrock Shake Return to McDonald’s in 2025?
Mark your calendars: Starting February 10, 2025, the Shamrock Shake is officially back in participating McDonald’s restaurants nationwide, just in time to help you usher in the spring season and get into the St. Patrick’s Day spirit. The classic shake—and its fan-favorite companion, the Oreo Shamrock McFlurry—are available through March 23, 2025, or while supplies last.
- Release date: February 10, 2025
- End date: March 23, 2025 (St. Patrick’s Day weekend)
- Availability: At participating U.S. locations, while supplies last
This season, McDonald’s is also running a charity campaign: For every Shamrock Shake purchased between February 10 and March 23, a donation of $0.25 will be made to Ronald McDonald House Charities (RMHC), aiming to support families in need during their most challenging times.
What Flavors Are Available for 2025?
McDonald’s sticks to its enduring formula of seasonal success with two returning Shamrock-inspired desserts:
- The Classic Shamrock Shake: A creamy blend of vanilla soft serve and minty Shamrock syrup, finished with a wave of whipped topping—this is the iconic green treat that started it all.
- Oreo Shamrock McFlurry: A twist introduced in recent years, this treat combines the same vanilla soft serve and mint Shamrock syrup with crunchy OREO cookie pieces swirled throughout for a rich, refreshing bite.
Both desserts are exclusively available for a limited time and are a must-try for mint lovers or anyone looking to join in on the St. Patrick’s Day festivities. Make sure you ask about both—the shake and the McFlurry—at your local restaurant, as some locations may have limited stock of one or the other.

Why Do Fans Love the Shamrock Shake?
The Shamrock Shake is much more than a beverage—it’s a cherished seasonal ritual associated with the excitement of welcoming spring and celebrating St. Patrick’s Day. Fans eagerly await the shake’s limited appearance, prompting a nationwide shake-hunt as green-tinged drinks start popping up each February. Here’s what makes the Shamrock Shake a perennial favorite among McDonald’s fans:
- Nostalgia: Many adults have fond childhood memories of seeking out Shamrock Shakes when they first appeared decades ago, passing on the tradition to future generations.
- Status as a St. Patrick’s Day symbol: With its minty flavor and signature green hue, the shake has become an edible icon of the holiday.
- Limited-time exclusivity: Its brief, once-a-year run makes its return a special event worthy of celebration.
- Flavor profile: Cool mint combined with rich, creamy vanilla soft serve creates a distinctively refreshing taste.
The Original Shamrock Shake: How Did This Tradition Start?
The Shamrock Shake has an interesting origin story. It was created in 1967 by Hal Rosen, a McDonald’s Owner-Operator in Connecticut, who developed the dessert specifically to honor St. Patrick’s Day. The shake made its national debut in 1970, and quickly achieved cult status.
Over the past fifty years, the Shamrock Shake has grown from a regional novelty to a beloved national treat, drawing crowds every year and sparking new variations—like the Oreo Shamrock McFlurry. Today, it endures as America’s most famous green milkshake and a central part of McDonald’s spring menu.
Meet Uncle O’Grimacey: McDonald’s St. Patrick’s Day Mascot
A quirky and lesser-known chapter in the Shamrock Shake lore involves Uncle O’Grimacey, a special character introduced in 1975 to promote the shake. With his all-green look, shamrock-adorned vest, jaunty hat, and cane, Uncle O’Grimacey hailed as Grimace’s Irish relative and embodied the festive spirit of the shake.
Uncle O’Grimacey hasn’t been a regular mascot in recent years, but fans still recall his whimsical television appearances and green-themed adventures, which helped solidify the Shamrock Shake’s reputation as the fun centerpiece of McDonald’s seasonal marketing during the 1970s and 1980s.
What’s in a Shamrock Shake?
If you’re curious about the secret to the Shamrock Shake’s unique taste, here’s what you’ll find in every cup:
- Vanilla soft serve – The creamy base delivers the shake’s thick, rich texture.
- Mint-flavored Shamrock syrup – This is what gives both the color and the signature fresh, minty flavor.
- Whipped topping – Swirled high, providing a classic ice cream shop finish.
- Optional cherry – Some locations top it all off with a bright red cherry for extra visual flair.
The Oreo Shamrock McFlurry adds one extra delight: crunchy Oreo cookie pieces, making it a favorite for those who like a bit more texture and chocolatey contrast with their mint.
