Does Costco publish nutrition facts for its strawberry banana smoothie?

No. Costco does not post food court nutrition on its website, and the frozen smoothie fruit sold in warehouses is not listed in the online catalog with a panel you can check. Any exact figure you find attached to the Costco name online came from a third-party database or a photograph of in-store packaging.

Is the Costco food court smoothie the same as the frozen packs?

No, and treating them as one thing is where most of the confusion starts. The food court drink is a prepared base blended to order behind the counter. The frozen packs in the aisle are bags of fruit you take home and blend yourself. They share a flavor name and very little else.

What liquid should I use with a Costco strawberry banana pack?

Water if you want the fruit to be the whole drink. Unsweetened almond milk if you want a little body for almost nothing. Whole milk or juice if you want it richer or sweeter and you have decided that is worth it. The table above shows what each choice does.

Is a strawberry banana smoothie high in sugar?

The sugar in a fruit-only build comes from the fruit, and banana brings more of it than strawberry does. That is a floor you cannot get under without changing the drink. What you can control is everything added on top: juice, honey, sorbet, sweetened yogurt. Those are choices, not requirements.

How do I add protein to a strawberry banana smoothie?

Plain greek yogurt, cottage cheese or a scoop of whey or pea protein all sit well with this flavor. Yogurt and cottage cheese have the advantage of also giving you the thickness people usually chase with whole milk or ice cream, so they do two jobs at once.

Can I make a Costco-style strawberry banana smoothie lighter without it tasting thin?

Yes. Frozen cauliflower is the usual trick. It blends invisibly into strawberry and banana and gives you volume and thickness without flavor. Greek yogurt over unsweetened almond milk does the same for creaminess. Keep the banana, though. It is what makes the drink taste like the drink.

Costco copycat

Costco Strawberry Banana Smoothie Nutrition

Costco publishes nothing for it. Here is what the drink is actually made of, and what it costs you to build at home.

Short answer

Costco does not publish nutrition figures for its strawberry banana smoothie, so there is no official number to quote. Rebuilt at home, the same drink runs from 180 to 393 calories, and the gap is almost entirely down to what you pour over the fruit.

Independent analysis. Smoothie Calculator is not affiliated with, endorsed by, or sponsored by Costco.

Costco does not publish nutrition figures for a strawberry banana smoothie. Not for the food court cup, not for the frozen fruit packs people buy by the bagful. Search results that quote a precise calorie count for it are pulling from user-submitted databases and photos of in-warehouse labels, not from Costco. So this page does the only honest thing available: it rebuilds the drink and shows you what the parts cost.

That matters more here than for most copycat pages, because the thing most people are actually asking about is a bag of frozen fruit. A strawberry banana pack is strawberries and banana. It has no liquid in it. Whatever you pour over it, whether that is water, juice, whole milk or oat milk, is a decision you make at the blender, and it is the single biggest lever on where the drink ends up.

So the useful question is not what Costco puts in its version. It is what you put in yours, and that one is answerable. The table below rebuilds the drink five ways. Every build starts with frozen strawberries and banana; what changes is the liquid and the base. Run your own pack and pour through the smoothie calorie calculator if your proportions differ.

Every build starts with frozen strawberries and frozen banana. The water build and the orange juice build use identical fruit, so the only thing separating them is the pour. Totals are summed from per-100 g values in the Smoothie Calculator ingredient database, one serving each.

What actually sets the number

The pack is fruit; the liquid is a separate decision

A frozen strawberry banana pack is exactly what it says: fruit, frozen, in a bag. It contains no liquid, no dairy, no sweetener. That means the bag's own panel tells you almost nothing about the drink you end up holding. The number you care about is set after you open it.

Banana is the heavier half of the pair

Strawberries are mostly water. Banana is not. It is the dense, starchy-sweet part of the blend and it carries most of what the fruit contributes. Packs that lean banana-forward for texture land higher than packs that lean strawberry, even when the bag weight is identical.

Juice bases are the cheapest way to add a lot

Blended drinks sold ready-made usually start from a juice or fruit puree base rather than water, because it is sweeter, cheaper and pours consistently. Do the same at home, orange juice over the fruit instead of water, and the total moves before a single spoonful of anything else goes in.

Cup size, not recipe, is what makes a counter-bought drink big

Food court cups are sized for a warehouse, not a snack. A blend that is unremarkable per cup becomes a lot of drink once it is poured into something you carry with two hands. When you compare a home build to a counter-bought one, check the serving before you compare anything else.

Added sweetener does exactly one job

Honey, agave, turbinado and fruit-juice concentrate all do the same thing to the total: they add sugar and nothing else. On an already-sweet strawberry banana base they are the easiest line to remove, and the one most likely to be there in a version you did not build yourself.

How to build it lighter without losing the drink

Pour the liquid, do not glug it

Measure the liquid the first few times. A cup of juice looks like nothing going into a full blender jug, and it is the easiest thing in the whole build to overpour without noticing you have done it.

Buy the fruit, not the smoothie

Bulk frozen strawberries and a bag of frozen banana slices give you the same drink as a pre-mixed pack, with the ratio under your control. Freeze ripe bananas yourself in portions and you get consistency without paying for the packaging.

Swap the sweetness source, not the sweetness

If the drink tastes flat on water, reach for a riper banana or more strawberry before you reach for honey. Fruit sugar arrives with fiber attached. A spoon of syrup arrives on its own.

Use greek yogurt for the body you think milk gives you

Whole milk makes a smoothie creamy by adding fat. Plain greek yogurt over unsweetened almond milk does the same job on texture and brings protein along with it. Same taste, different build.

Price your own strawberry banana build

Change the liquid, the banana or the base and watch the total move.
