  "textContent": "\n\n\n\n**St. Patrick’s Day** energy has __officially__ hit drive-thrus for 2026. While **McDonald’s** continues its reign with their legendary **Shamrock Shake** , there are a few newcomers (specifically, Sonic’s electrifying new slush and the **all-new sundae at Costco’s food court**) that are shaking up the seasonal menu item game. This year’s lineup of St. Patrick’s Day food has something for everybody, whether you’re more of a **mint-chocolate** lover or a sour apple seeker.\n\n* * *\n\n## We’ve curated the ultimate list of the 7 best St. Patty's fast food items you need to snag before they quickly vanish from menus after the holiday.\n\n###\n\n\n\n\n### Sonic Sour Shamrock Slush\n\nSonic's St. Patrick's Day offering is shaking things up by embracing sour flavors rather than the expected mint-chocolate combo. The **Sour Shamrock Slush** features a tangy green apple slush base loaded with sour popping candy and a whipped cream topping. The top of the drink is covered with even more popping candies and finished with a tart rainbow candy strip for festive vibes.\n\nThe Sour Shamrock Slush is available now for $3.99 (20 ounces) at participating Sonic locations nationwide and through the Sonic app for a limited time through the end of March.\n\n###\n\n\n\n\n### Dairy Queen Mint Crunchin’ Cookie Dipped Cone + Mint Oreo Blizzard\n\nDairy Queen is turning up the minty-ness for St. Patty's this year. First up on their limited-time menu is the **Mint Crunchin' Cookie Dipped Cone** , which features Dairy Queen’s classic vanilla soft serve dipped in a green mint-flavored coating spotted with chocolate cookie crumbles. DQ’s Blizzard of the Month, the **Mint Oreo Blizzard** , boasts a blend of Oreo pieces, crème de menthe, and soft serve. Both are only available for a limited time, so make sure to head to your closest Dairy Queen _quick_.\n\n###\n\n\n\n\n### Costco Double Chocolate Mint Sundae\n\nThough it's not technically a fast food joint, Costco's food court is home to many of our favorite fast food-esque items (looking at you, hot dogs). A new offering _just_ hit the food court ahead of St. Patty’s Day: the Double Chocolate Mint Sundae. This frozen dessert is made with a mint-flavored soft serve ice cream laced with a chocolate fudge sauce and chocolate cookie crumbles. Find it in select Costco food courts for $2.99 for a limited time!\n\n###\n\n\n\n\n### McDonald's Shamrock Shake + Oreo Shamrock McFlurry\n\n _Oh, so classic!_ McDonald's Shamrock menu is a must for anyone celebrating St. Patty's at the drive-thru. Two festive treats, the Shamrock Shake and Oreo Shamrock McFlurry, first hit restaurants on February 17 and will be available for a limited time through St. Patrick’s Day, March 17.\n\nThe classic **Shamrock Shake** is made with vanilla soft serve blended with a minty syrup and topped with whipped light cream, while the **Oreo Shamrock McFlurry** boasts a bit of a thicker texture but is made with a similar soft serve and mint syrup formula, just speckled with Oreo cookie pieces instead.\n\n###\n\n\n\n\n### Shipley Donuts St. Patrick’s Day Donuts\n\nShipley Donuts is serving up St. Patrick’s Day-themed donuts from March 4 to 17 at participating locations, frosted with white, green or chocolate icing and topped with holiday-themed sprinkles. They look _stunning._\n\nThe festive donuts are available for individual purchase, in a half dozen, or in a Lucky Dozen box (pictured above) that comes with four of each donut variety while supplies last. _Run, don't walk!_\n\n**Subscribe toour newsletter for more can't-miss fast food menu updates + deals!**",
