A high-protein smoothie is one of the easiest ways to add a premium, made-to-order item to a breakfast, café or grab-and-go menu. This guide gives foodservice operators a 24-serving batch formula for a strawberry, blueberry and banana protein smoothie, plus a freezer-pack prep system, blending technique, protein options and menu variations, all built around IQF fruit.

Why build smoothies on IQF fruit

Fresh berries and bananas are hard to manage in a smoothie program. Strawberries bruise, blueberries vary from case to case, and bananas go from green to brown in a few days. IQF strawberries, IQF blueberries and IQF banana slices are frozen individually at peak ripeness, so they stay loose in the bag, portion by weight and go straight into the blender. Frozen fruit also chills the drink as it blends, so you need little or no ice, and the smoothie comes out thicker and more flavorful instead of watered down.

Batch ingredients for 24 smoothies

Fruit and add-ins (freezer packs)

Protein and liquid (added at the blender)

*Protein estimate is for nonfat Greek yogurt, dairy milk and a typical 25 g scoop of protein powder. The actual number depends on your brands, so confirm it with your own nutrition analysis before you print it on a menu or label.

Prep freezer packs before service

The fastest smoothie programs never weigh fruit during the rush. Instead, they pre-portion every dry and frozen ingredient into a single pack that goes straight into the blender.

1. Keep everything frozen. Work in small batches so the IQF fruit stays frozen and free-flowing while you portion. Fruit that thaws and refreezes clumps into a block.
2. Weigh each pack. Add 3 oz strawberries, 2 oz blueberries, 2.5 oz banana, plus the chia and oats if you use them, to a labeled freezer bag or lidded cup.
3. Label and date. Mark the flavor, date and any allergens on each pack, and store at 0°F (-18°C) or colder.
4. Stage the protein. Pre-scoop protein powder into small cups, or keep it in a bin with a fixed-size scoop at the blender station.
5. Pre-measure the liquid. Use a marked pitcher or measured pour spout so every smoothie gets the same 6 fl oz.

How to blend a thick, smooth protein smoothie

1. Add the liquid to the blender container first, then the Greek yogurt and protein powder. Putting powder near the liquid keeps it from sticking to the walls.
2. Add one freezer pack on top.
3. Start on low for 5 to 10 seconds to pull the frozen fruit into the blades, then blend on high for 30 to 45 seconds until completely smooth. Use the tamper if the fruit stalls.
4. Pour into a 16 oz cup and serve right away. Blend one or two smoothies per container for the most consistent texture.

Texture target: thick enough to coat a spoon but still easy to drink through a standard straw. If the smoothie is too thick, add milk 1 fl oz at a time. If it’s too thin, add a few pieces of frozen banana and pulse.

Choosing a protein source

• Greek yogurt adds protein, tang and a creamy body, and it is the simplest base for a clean-label menu.
• Whey protein mixes smoothly and has a neutral flavor, but it contains dairy.
• Pea protein is a dairy-free option for plant-based menus. Pair it with oat or soy milk and a dairy-free yogurt. Pea protein is slightly earthy, and the berries and banana cover it well.
• Silken tofu or nut butter can replace part of the protein powder for a smoother texture. Nut butter adds a tree nut or peanut allergen to the drink.

Holding and food safety

• Use purée that has been pasteurized or given an equivalent kill step. In the US, fruit purée used in drinks is regulated as juice and must get one. IQF fruit pieces are not juice, so they are not covered by that rule.
• Keep IQF fruit and freezer packs at 0°F (-18°C) or colder until use, and never refreeze fruit that has thawed.
• Hold Greek yogurt and milk at 41°F (5°C) or below.
• Blend to order. A blended smoothie starts to separate within about 15 minutes.
• Post allergen information for dairy, soy, nuts and gluten. Oats can carry gluten unless they are certified gluten-free.

Five menu variations from the same station

• Tropical protein: swap the berries for IQF mango and pineapple chunks, and use coconut milk.
• Açaí berry power: replace the blueberries with 3.5 oz frozen açaí purée for a deep purple color. Serve the thick version as a bowl with our açaí bowl batch method.
• Pink pitaya: add a pitaya smoothie pack in place of the blueberries for a bright pink drink.
• Peanut butter banana: drop the berries, double the banana and add 1 Tbsp peanut butter.
• Extra creamy: add 1.5 oz IQF avocado chunks for a silky texture with no avocado flavor.

Frequently asked questions

Do you need ice in a smoothie made with frozen fruit?

Usually not. IQF fruit chills and thickens the drink on its own, so adding ice only dilutes flavor. If your liquid is warm or your fruit has started to soften, add a small handful of ice.

Can smoothie packs be made ahead?

Yes. Pre-portioned freezer packs of IQF fruit, chia and oats hold well at 0°F (-18°C). Add yogurt, protein powder and liquid at the blender, not in the pack.

How much protein is in this smoothie?

With nonfat Greek yogurt, dairy milk and a 25 g scoop of protein powder, expect roughly 35 g per 16 oz serving. Confirm the number with your own ingredients before putting it on a menu.

Can I make it dairy-free?

Yes. Use pea protein, oat or soy milk and a dairy-free yogurt. The fruit formula stays the same.
