Smoothie King adds protein flatbreads to expand beyond drinks

Smoothie King is moving past the cup and into the meal with protein-packed flatbreads in Chicken Chipotle, Chicken Ranch and Chicken Pesto. The new items are set to begin rolling out across stores June 23 as a permanent menu category, signaling that the chain sees protein as the easiest way to turn a smoothie visit into a fuller lunch or snack purchase.

The timing fits a broader strategy. The flatbread announcement landed alongside free Hydration Watermelon Smoothies for National Smoothie Day, but the food expansion is the more telling move. Smoothie King has been building toward this for years, first adding smoothie bowls in 2023 and later launching its nationwide Power Eats menu on August 26, 2025. That rollout started with three loaded toasts and two protein boxes, with additional items planned for early 2026. Taken together, the moves show a brand trying to own more of the daypart, not just the beverage moment.

Protein sits at the center of that shift. By bringing savory chicken flatbreads into a chain known for fruit, yogurt and blended drinks, Smoothie King is stretching into lunch and early-dinner occasions without abandoning its wellness positioning. The company said in April that flatbreads and other high-protein items were part of a larger brand-evolution plan that also includes store redesigns, national advertising and broader growth efforts. Smoothie King also said it will add ovens across its system at no cost to existing franchisees, a practical step that makes the menu expansion possible at scale.

The business case is clear in the numbers. Smoothie King’s average unit sales were $662,015 in 2025, up from $659,567 in 2024, while system sales rose 4.4% to more than $760 million. The chain ended 2025 with 1,242 units, up from 1,103 at the start of 2023, and it has more than 200 new store commitments plus over 1,500 available trade areas in its development pipeline. Compared with Tropical Smoothie Cafe, which has long used food to broaden its daypart reach and posts roughly $1 million in average unit volume, Smoothie King is still catching up, but the flatbreads narrow the gap in a category that matters.

The watermelon comeback reinforces the same logic from the drink side. Smoothie King brought back its watermelon smoothies for Summer 2026 on May 12, positioning the limited-time line around real fruit, no artificial flavors and hydration. The company said watermelon is one of its most beloved seasonal flavors, and the menu can be customized with protein, energy or immune-support add-ons. That kind of cross-pollination is the point: protein is becoming the bridge that lets Smoothie King sell a more complete, more profitable visit without losing the identity that made the brand work in the first place.
