More Sonic Summer Goodness: Two Returning Slushes + New Snack!
Sonic
Sonic’s bringing back two slush flavors that haven’t been seen for years.
First up is the Watermelon Slush, which was last featured on their menu in 2019. Fans even petitioned with nearly 3,000 signatures urging the chain to bring it back! Watermelon-flavored anything is great for beating the summer heat, so we can’t wait to cool down with this frozen bev! A medium size starts at $2.79 (without tax).
The Lemonberry Slush will also hit Sonic’s summer menu for the first time since 2020. It’s crafted with real strawberries and lemon for a sweet, yet tart sip! A medium size starts at $3.29 (without tax).

As far as food goes, there’s a new savory Sonic treat on the horizon: Cheesy Garlic Pepperoni Bites. These pizza-like bites feature both mozzarella and provolone cheeses, some pepperoni, and pizza sauce wrapped in a crispy shell. They’ll be orderable in a three, five or seven-piece starting at just $2.99 (without tax)!
Sonic’s new refreshing summer lineup will drop on May 27 in the Sonic app, with a wider national rollout scheduled for June 2.
