Strawberry Banana Smoothie Recipe (Thick and Creamy)
The difference between a strawberry banana smoothie that stands up in the glass and one that separates into pink water in ten minutes comes down to a single decision: frozen fruit instead of ice.
Ice is frozen water and nothing else. As it melts it takes everything with it, so the last third of the glass tastes like nothing. Frozen fruit chills the drink exactly the same way while carrying flavour and body along with it. That one swap, plus the blending order below, is the whole recipe.
Why You'll Love This Recipe
- Thick enough to eat with a spoon, and it stays that way for the twenty minutes it takes to actually drink it.
- Five minutes, one blender, four core ingredients.
- No strawberry grit, because of a two-stage blending method that most recipes skip.
- The ratio is given as a ratio, so you can scale it to one glass or five without guessing.
Blend in two stages, not one. Put the liquid, yogurt and frozen strawberries in first and run the blender a full 45 seconds, until it is completely smooth. Then add the frozen banana and blend only 20 seconds more. The reason is that the two fruits need opposite things. Strawberry seeds and skins take real time to disappear, and a short blend leaves that faint sandy texture people assume is just what strawberries do. Frozen banana is the opposite: it goes thick and creamy fast, and every extra second of blade friction generates heat that thins it back out. Blend them together for one long spin and you are always compromising one of them. Split it, and you get a smoothie that is both smooth and thick.
Read Before You Start
No ice. None. If your smoothie needs to be colder, freeze more fruit. Every ice cube you add is a small amount of flavourless water waiting to dilute the glass. This is the single biggest quality difference between a homemade strawberry banana smoothie and one that tastes like a shop-bought slushie.
Load the blender liquid first, frozen last. Milk and yogurt at the bottom, around the blades, then the frozen fruit piled on top. Do it the other way round and the frozen chunks bridge over the blades, the blades spin in an air pocket, and you end up stopping every ten seconds to poke at it with a spoon. The liquid at the bottom is what starts the vortex that pulls everything else down.
Ingredient Deep Dive & Notes
Frozen strawberries. Two cups, about 280 g. Frozen beats fresh here for texture and usually for flavour too, since fruit destined for freezing is picked riper. If you are freezing your own, hull and halve them first so they blend faster.
Frozen banana. One large, sliced into coins and frozen at least 2 hours ahead. This is the only ingredient that needs planning, and it is worth the planning. A fresh banana in this recipe gives you a thin, sweet drink rather than a smoothie. Freeze a tray of coins whenever bananas get spotty and keep them bagged.
Ripeness matters for the banana. Spotted and sweet, but not black. Black bananas are noticeably stronger in flavour, and in a drink that is meant to taste of strawberry as much as banana, they take over.
Milk. One cup. Whole milk gives the richest result. Unsweetened almond, oat or soy all work and change the flavour more than the texture. Oat milk is the closest substitute for body.
Greek yogurt. Half a cup, full-fat and plain. It adds thickness and a slight tang that stops the drink tasting flat and one-note sweet. It is optional, and the FAQ covers what to do without it.
A pinch of salt. Not optional, and it does not make the smoothie taste salty. Salt suppresses bitterness and makes the fruit read as sweeter, which usually means you need less honey or none at all.
Honey or maple syrup. One to two teaspoons, and taste before adding any. Ripe fruit is often sweet enough on its own. Add it at the end, never at the start.
Vanilla extract. Half a teaspoon, alcohol-free, in keeping with the other recipes on this site. It rounds the dairy and fruit together.
Do not substitute the frozen fruit with fresh fruit plus ice. Everything else here is flexible. That one swap changes the drink into something else, and no amount of blending fixes it.
Equipment Needed
- Any blender works, but the motor matters more than the brand. A high-speed blender handles this in about a minute. A standard blender needs the frozen strawberries broken up a little first and may need an extra splash of milk.
- Tamper, if your blender came with one. It is the correct tool for pushing frozen fruit into the blades, and a spoon is not, for obvious reasons.
- A rimmed tray and parchment for freezing banana coins in a single layer.
- Measuring cup. Smoothies are a ratio recipe and eyeballing the liquid is where thin smoothies come from.

Getting the Texture Right
Either ice went in, or the fruit was not frozen, or there was too much liquid. The working ratio is roughly 1 part liquid to 2 1/2 parts frozen fruit by volume for a thick smoothie, and 1 to 2 for something you can drink through a straw easily.
The strawberries were not blended long enough before the banana went in. That first 45-second stage is what breaks down the seeds and skins.
The banana was too ripe, too warm, or the smoothie sat before drinking. Cut banana browns on contact with air, and freezing it slows that reaction down considerably. Use frozen coins and drink it fresh.
There is nothing holding the mixture together. Yogurt helps, and so does a tablespoon of rolled oats or half a teaspoon of chia blended in, which adds body without changing the taste much.
Frozen fruit bridged over the blades. Liquid goes in first, always, and a tamper solves the rest.
How to Use This Base
How to Serve, Store & Reheat
Straight away, in a chilled glass if you have one. Thickness fades as it warms, so this is a drink that rewards being made last rather than first.
It is at its best within ten minutes. If you need to hold it, fill a jar to the very top so there is minimal air, seal it and refrigerate up to 24 hours. Expect separation and some colour dulling, and shake or stir hard before drinking.
Not applicable. This is a cold drink and warming it does nothing good.
The finished smoothie freezes solid and thaws unevenly, so it is not worth it as a drink. Freeze it in popsicle moulds instead, or freeze the fruit in portioned packs and blend fresh, which gives a much better result for the same amount of planning.
Dietary Variations & Adaptations
Oat milk plus a coconut yogurt is the closest match for texture. Alternatively drop the yogurt entirely and use a quarter of an avocado, which sounds odd and works well: it adds body and fat without any detectable flavour against the strawberry.
Add a scoop of vanilla or unflavoured protein powder with the liquid at stage one, and an extra 2 tablespoons of milk, since powder absorbs liquid and thickens the drink. Adding it at the end leaves streaks.
Halve everything and skip the honey entirely. Blended with less liquid and frozen into moulds, this is a better use of the recipe for small children than a full glass.
“The creaminess in a good strawberry banana smoothie does not come from the dairy. It comes from what freezing does to a banana. As a banana freezes, water inside its cells turns to ice crystals that expand and puncture the cell walls from the inside. Nothing much happens while it stays frozen. The moment you blend it, all that ruptured tissue releases its pectin and starch at once into the liquid, and what forms is a thick colloidal suspension rather than a fruit purée sitting in milk. That is the exact same mechanism behind one-ingredient banana ice cream, which contains no cream at all and still eats like soft serve. It is also why a fresh banana cannot produce the same result no matter how long you run the blender: the cell walls are still intact and the pectin stays locked inside them. Freeze the banana and the texture is chemistry. Skip it and you are just drinking cold fruit milk.

That is ingredient preparation, in the same way a cake recipe expects softened butter, and it is not counted in the total. <a id="recipe-card"></a>”
Allergen Notice: This recipe contains milk. Substitutions: oat, almond or soy milk and a plant-based yogurt in place of the dairy, or avocado in place of the yogurt entirely. There is no wheat, egg, or nut in the base recipe, though almond milk and protein powders introduce them. Brand formulations vary and change over time, so read labels yourself when making this for someone with an allergy. Nothing here should be treated as safe for a specific allergy on my word.

Step-by-Step Instructions
Follow along and mark each step complete as you cook
Peel and slice the banana into 1/2 inch coins, spread on a parchment lined tray and freeze at least 2 hours, then bag. Skip this step if using fruit frozen earlier.
Add the milk, yogurt, vanilla and salt to the blender first, then the frozen strawberries. Hold the banana back.
Blend from low to high for 45 seconds, until a vortex forms and the mixture is completely smooth with no seed grit when rubbed between your fingers.
Add the frozen banana coins and blend on high for 20 seconds only, until thick and pale pink. Do not blend longer.
Check the thickness by pulling a spatula through. It should hold a soft ribbon briefly. Add milk a tablespoon at a time to loosen, or more frozen strawberries to thicken.
Taste, add honey only if needed, and serve within 10 minutes.
