Burger King Sourdough King Returns: Inside the 2021 Fast Food Revival
Burger King's iconic Sourdough King is back for a limited time, blending classic flavors with a quirky new promo for fans and newcomers alike.
Burger King’s Sourdough King Makes a Limited-Time Comeback in 2021
Burger King made headlines when it announced the much-anticipated return of the Sourdough King for a limited run in early 2021. A long-time fan favorite praised for its delicious combination of savory ingredients, the Sourdough King stands out in a world of ordinary burgers by sporting rich, toasted sourdough slices as its bun. This move reflects the ongoing popularity of sourdough bread in the food world, giving fast food fans one more way to enjoy the trend.
What Is the Sourdough King?
The Sourdough King is more than just a burger; it’s a celebration of textures and flavors. The base model features:
- A quarter-pound savory burger patty
- Thick-cut smoked bacon
- Melted American cheese
- Ketchup
- Mayonnaise
- All nestled between two crispy, toasted sourdough bread slices
The result is a sandwich that balances the smokiness of bacon, the creamy sharpness of American cheese, and a buttery crunch from the sourdough, all while classic condiments add a familiar fast food flair. For those with a hearty appetite, Burger King even offers a double version, featuring two burger patties for extra protein and indulgence.
Why Sourdough?
2020 and 2021 saw a boom in sourdough’s popularity, both in homes and restaurants. While home bakers might be fatigued from tending to sourdough starters, the craving for the unique tang and crunch of sourdough bread remains. Fast food brands, Burger King included, have tapped into this trend by integrating sourdough into their menus.
The Return for 2021: What’s New?
Burger King isn’t just bringing back the classic Sourdough King—the chain is spicing things up with a limited-time promotion that puts a whimsical twist on customer engagement. From launch through April 19, 2021, fans have the opportunity to enjoy this fan favorite with some exciting extras.
