Getting Your Ingredients Ready
- Strawberries: hull and halve 1 cup (about 8 to 10 medium berries). If frozen, measure straight from the bag, no thawing needed.
- Blueberries: rinse and measure 1/2 cup. Frozen go straight in.
- Banana (optional): peel and slice 1/2 a banana if you want a creamier, sweeter result.
- Base liquid measured and ready: 1 cup of unsweetened almond milk works well; oat milk makes it richer; water keeps it lightest.
- Optional add-ins portioned out: 170g of Greek yogurt or 1 scoop of protein powder if you want a high-protein version.
Equipment Setup
- Blender is clean and assembled, with the lid within reach before you start pouring.
- Pour the liquid in first, starting with about 3/4 cup and topping up after the first blend.
- Add fruit in order: banana (if using) on the bottom near the blades, then strawberries, then blueberries.
- Dense add-ins go in last. Greek yogurt, protein powder, or chia seeds sit on top of the fruit.
Blending
- Secure the lid firmly before switching the blender on.
- Start on low for 10 seconds, then move to high.
- Blend for 45 to 60 seconds, until the sound smooths out into a steady hum.
- Tilt the jar to check for unblended chunks, and run it another 10 seconds if you spot any.
Taste & Adjust
- Taste before adding anything. Ripe fruit is often sweet enough on its own.
- Too thick? Add liquid 30ml at a time and pulse briefly.
- Too thin? Add a few more frozen berries or 1 tablespoon of rolled oats.
- Too tart? The blueberries can bring an edge, so add 1/2 a banana or a pitted date and blend again.
- Not sweet enough? Taste first, then add a pitted Medjool date rather than sugar.
Serve & Store
- Pour into a glass right away for the best texture.
- Top with a few fresh berries or a sprinkle of chia seeds if you're serving guests.
- Drinking later? Seal it in a jar and refrigerate, then drink within 24 hours.
- A squeeze of lemon juice helps keep the color bright if it's stored.
- Rinse the blender straight away, since berry residue stains if it dries on.
Before You Start: What You Need to Know
1. Ingredients
Core Ingredients
This recipe keeps the list short on purpose. The strawberries bring sweetness and vitamin C, the blueberries add a deeper, slightly tart flavor and antioxidants, and the liquid controls how thick or thin the smoothie turns out.
All quantities below are for 1 serving. Scale up proportionally for more.
Optional Add-Ins
The base recipe is complete on its own, but add-ins are where a blueberry strawberry smoothie shifts from a simple fruit drink to something that fits a goal. For breakfast, protein and fat keep you full; for recovery, protein does the heavy lifting.
Start with one add-in at a time so you can taste what each one changes before layering more.
- Banana (1/2 to 1 medium): adds creaminess, natural sweetness, and potassium. Blend it in early near the blades.
- Greek yogurt (170g): adds about 17g of protein and a tangy, thick finish. Stir-friendly and blends smooth.
- Protein powder (1 scoop): adds 20 to 25g of protein. Vanilla or unflavored keeps the berry flavor clean.
- Chia seeds (1 tablespoon): adds 4g of fiber and omega-3s. Blend rather than stir for the best texture.
- Spinach (1 handful, ~30g): disappears behind the berries in flavor while adding iron and folate. A good first green.
- Nut butter (1 tablespoon): adds healthy fat and staying power, plus a subtle nutty note that suits blueberries.
Best Ingredient Substitutions
Swaps matter most when something is out of season, unavailable, or doesn't fit your diet. None of these break the recipe; each one shifts the result a little.
The most useful swap is also the least obvious, since trading fresh berries for frozen usually improves the smoothie, giving you a thicker, colder, more concentrated drink.
2. Nutrition Facts
Most people make a strawberry and blueberry smoothie for one of two reasons. Some want the vitamin C and fiber for everyday health, while others track calories and protein for a goal like weight or recovery. The numbers below cover both.
Per serving (~400 ml), based on 1 cup frozen strawberries, 1/2 cup frozen blueberries, and 1 cup unsweetened almond milk, with no yogurt.
Estimates based on USDA FoodData Central values for the quantities listed, with fortified almond milk. Figures vary with brands, exact amounts, and any add-ins.
Homemade vs. kencko Purples: Nutrition Side by Side
The homemade version uses a full cup of strawberries plus blueberries, so it carries more total fruit, fiber, and vitamin C per glass. The kencko Purples sachet is a concentrated freeze-dried blend, which is why one packet sits lower in calories and sugar while still counting as real fruit.
Homemade figures are USDA FoodData Central estimates for the quantities above. kencko Purples figures come from the product nutrition label (1 sachet, 18g, mixed with water). Neither option contains added sugar.
How Nutrition Changes with Add-Ins
The base recipe is a solid start, and the right add-in tilts it toward a goal, whether that's more protein for recovery, more fiber for fullness, or more fat to slow digestion. The table shows the practical impact of each common addition.
3. Health Benefits of a Strawberry Blueberry Smoothie
Two berries in one glass cover more nutritional ground than most single-fruit smoothies. Here's what the research points to for the main ingredients, framed honestly.
- High in Vitamin C: A cup of strawberries delivers close to a full day's vitamin C, which supports immune function, collagen production, and iron absorption. Blending is gentler than cooking, so most of that vitamin C survives, though blend times over 60 seconds generate heat that can degrade it. Keeping the blender under a minute helps protect the nutrient.
- Rich in Antioxidants: Blueberries are one of the most studied fruits in nutrition, and the anthocyanins behind their deep blue-purple color are linked to antioxidant activity. Pairing them with strawberries gives you two different antioxidant profiles in a single drink rather than one.
- Good for Gut Health and Fullness: Whole berries keep their fiber, unlike juice, and one serving of this smoothie carries around 5g of it, roughly 18% of the daily target. That fiber slows sugar absorption, feeds gut bacteria, and helps the drink keep you full longer than a fruit juice would.
This matters because most of us fall short on produce in the first place. Only 12.3% of US adults eat enough fruit, and 10% eat enough vegetables, according to CDC data. A two-fruit smoothie is one of the easiest ways to close part of that gap.
4. Equipment
A strawberry blueberry smoothie doesn't need special gear; most kitchens already have what's required. The quality of your blender matters most when you use frozen fruit or add fibrous extras like spinach.
Required Equipment
- Blender: a 700W or stronger blender handles frozen berries and greens without leaving chunks. A basic blender works fine for soft, ripe, fresh fruit, and the difference only shows up with frozen loads or greens.
- Measuring cup or kitchen scale: keeps your servings and nutrition tracking consistent. Useful rather than essential.
- Knife and cutting board: for hulling strawberries and slicing an optional banana. Frozen pre-cut fruit makes even these optional.
Optional but Useful
- Freezer-safe bags: portion out the fruit at the start of the week so each morning means adding liquid and blending. This one habit cuts active prep to under 2 minutes.
- Wide-mouth jar (500ml): best for storing a second portion in the fridge, and easier to clean than a narrow glass.
- Shaker bottle: all you need if you reach for a no-blender sachet instead of blending. No blender required at any point.
How to Make a Strawberry Blueberry Smoothie: Step by Step
This strawberry blueberry smoothie recipe is hard to get wrong, but following the steps in order gives you a smoother, better-textured result than throwing everything in at once. The order protects your blender and blends the fruit evenly.
Step 1: Prep Your Fruit
Wash and hull the strawberries, and rinse the blueberries. If you're using frozen fruit, measure it straight from the bag with no thawing. Ripeness matters more than people expect, since ripe strawberries are sweeter and blend smoother, so taste one first and plan to adjust sweetness later if they're flat.
Step 2: Add Ingredients in the Right Order
Liquid goes in first. Pour about 3/4 cup of almond milk in before anything else, since this creates the vortex that pulls fruit into the blades and stops the motor from stalling on frozen fruit. Add the banana (if using), then strawberries, then blueberries. Greek yogurt, protein powder, or chia seeds go in last, on top of the fruit.
Step 3: Blend
Secure the lid, start on low for 10 seconds, then move to high and blend for 45 to 60 seconds. You'll know it's ready when the motor sound smooths out from a loud churn to a steady hum. Tilt the jar to check the sides for unblended pieces, and run it another 10 to 15 seconds if needed.
Step 4: Adjust Consistency and Taste
Too thick? Add liquid 30ml at a time and pulse, since it's easier to thin than to thicken. Too thin? Add a few frozen berries or 1 tablespoon of rolled oats. Taste before sweetening, because ripe fruit often needs nothing extra; if it does, a pitted date beats sugar.
Step 5: Serve and Store
Pour right away for the best texture. A thick smoothie starts to separate within 10 to 15 minutes at room temperature, which is normal, so stir or shake before drinking. To store, seal it in a jar, refrigerate, and drink within 24 hours.
Top Tips for a Better Strawberry Blueberry Smoothie
1. Use Frozen Berries, Not Ice
Ice waters down the flavor as it melts. Frozen strawberries and blueberries keep the drink cold and thick while concentrating the berry taste, so freeze fresh berries the night before or keep a bag on hand.
2. Put Liquid in First, Every Time
Liquid creates the vortex that pulls everything into the blades. Starting with frozen fruit on the bottom risks stalling the blades and straining the motor on cheaper blenders. This applies to every smoothie, not only this one.
3. Balance the Tartness
Blueberries can bring a tart edge that strawberries don't. If your batch tastes sharp, half a ripe banana or a pitted Medjool date rounds it out far better than sugar, adding fiber alongside the sweetness.
4. Don't Over-Blend
45 to 60 seconds is enough for most blenders. Over-blending generates heat that can degrade vitamin C and turns the texture thin and airy. When the motor sound shifts to a steady hum, it's done.
5. Hit Your Protein Target the Smart Way
For a strawberry blueberry smoothie that actually keeps you full, 170g of Greek yogurt adds about 17g of protein with no flavor cost. Add a scoop of unflavored protein powder on top and you're at 30 to 40g per glass, more than most protein bars.
6. Add Greens Without Changing the Flavor
A 30g handful of baby spinach disappears behind the berries, shifting the color slightly toward deep purple while the flavor stays fruity. Baby spinach blends more completely than mature leaves or kale, so start there.
7. Prep Ahead to Save Time
Portion the fruit into labeled freezer bags at the start of the week. Each morning, tip a bag into the blender, add liquid, and blend, dropping active prep to under 2 minutes. If even that feels like too much on a weekday, a no-blender sachet skips the step entirely.
Variations Worth Trying
High-Protein Version
This is the easiest way to turn a strawberry and blueberry smoothie into a recovery drink. Add 170g of Greek yogurt for about 17g of protein, then a scoop of vanilla or unflavored protein powder to reach 30 to 40g per serving. Blend the yogurt in first so it emulsifies before the frozen fruit thickens everything up.
Dairy-Free and Vegan Version
Swap Greek yogurt for coconut or almond yogurt, and use oat milk for creaminess or almond milk to keep it light. This version is naturally vegan and gluten-free, and the flavor difference is small when the berries are ripe. For protein without dairy, 30g of hemp seeds adds around 10g, or 100g of silken tofu blends in smooth.
Kids' Version
Skip the greens on the first try and build up to them gradually. A few drops of pure vanilla extract soften the flavor better than added sugar. In summer, pour the mix into popsicle molds; kids who won't drink a smoothie will often eat it frozen.
Antioxidant Boost Version
Add a second deep-colored berry like blackberries or a tablespoon of pomegranate seeds for a darker, more layered antioxidant profile. A handful of spinach folds in iron and folate without changing the berry flavor. This is the version to reach for when you want the most produce per glass.
The Fastest Way: Skip the Blender
If prep time is the real barrier, a kencko Purples sachet contains freeze-dried banana, strawberry, blackberry, blueberry, raspberry, cranberry, dates, and apple fiber, with nothing else added. Mix it with ~300ml of water or milk in a shaker bottle, shake for 30 seconds, and one sachet covers 30% of your recommended daily fruit and vegetables. No cutting, no cleanup, no waste.
How to Store and Meal Prep This Recipe
- Refrigerating: store in a sealed jar for up to 24 hours. Separation is normal, so shake or stir before drinking, and a squeeze of lemon juice helps keep the color from dulling. A wide-mouth mason jar seals well and cleans easily.
- Freezing: the finished smoothie freezes for up to 3 months. Portion it into ice cube trays or freezer-safe containers, thaw overnight in the fridge, and re-blend for 10 seconds to bring back the texture. It holds flavor well, though it loses a little smoothness.
- Meal Prep: the real time saver is portioning the fruit, not the finished drink. Pack 5 to 7 freezer bags with strawberries, blueberries, and any add-ins, label each with the date, and each morning is only liquid, then blend. For a version with no portioning, fridge, or blender at all, a smoothie subscription box keeps shelf-stable sachets on hand for up to 18 months.
Skip the Blender: Try kencko Purple
Making a strawberry blueberry smoothie from scratch takes real time, between washing fruit, slicing, measuring, blending, and then cleaning the jar. On a busy weekday, that's the part that gets skipped, and the produce in the fridge goes to waste. It's also why most of us fall short on fruit and vegetables in the first place.
kencko's Purples sachet is freeze-dried banana, strawberry, blackberry, blueberry, raspberry, cranberry, dates, and apple fiber, nothing added, ready in 30 seconds with 300ml of water or milk in a shaker bottle. One sachet covers 30% of your recommended daily fruit and vegetables, with no preservatives, no added sugar, no freezer, and no cleanup. It costs less than a coffee run and counts toward your produce for the day: Try kencko Purples.
FAQs About Strawberry Blueberry Smoothies
Is a strawberry blueberry smoothie healthy?
A strawberry blueberry smoothie is healthy when it's made from whole fruit with no added sugar. One serving with frozen berries and unsweetened almond milk delivers over 100% of your daily vitamin C, about 5g of fiber, and only around 130 calories. What changes the health profile most is what you add, since Greek yogurt and chia seeds raise the protein and fiber, while flavored yogurt, juice, or ice cream push it toward dessert. Keep the base whole fruit and it stays a genuinely nutritious drink.
How many calories are in a strawberry blueberry smoothie?
A strawberry blueberry smoothie made with 1 cup of strawberries, 1/2 cup of blueberries, and 1 cup of unsweetened almond milk has about 130 calories. Adding 170g of Greek yogurt brings it to roughly 220 calories with 17g more protein. A scoop of protein powder adds another 120 calories and 25g of protein, enough to make it a full meal. Calories shift with fruit size, liquid choice, and any add-ins.
How do I make a strawberry blueberry smoothie without banana?
A strawberry blueberry smoothie without banana is easy, since the banana mainly adds creaminess and sweetness rather than structure. Use frozen berries to keep it thick, and add 170g of Greek yogurt or 2 tablespoons of rolled oats for body. If it tastes too tart without the banana's sweetness, a pitted Medjool date balances it without refined sugar. Silken tofu is another option that adds creaminess and protein.
How do I make a healthy strawberry blueberry smoothie?
A healthy strawberry blueberry smoothie starts with whole fruit, an unsweetened liquid like almond milk or water, and no added syrups. Use ripe or frozen strawberries and blueberries, blend for under a minute to protect the vitamin C, and taste before sweetening. For extra nutrition without changing the flavor, add a handful of spinach and a tablespoon of chia seeds. Skip the fruit juice and flavored yogurt, since those are what turn a nutritious smoothie into a sugary one.
Can I make a strawberry blueberry smoothie without a blender?
You can make a rough strawberry and blueberry smoothie without a blender by mashing fully ripe berries with a fork and whisking in milk, though the texture stays chunky. For a smooth, blender-free result, a kencko Purples sachet dissolves completely in a shaker bottle with water or milk in about 30 seconds. The freeze-dried fruit needs no chopping, no freezer, and no cleanup. It's the most reliable way to skip the blender entirely.
How do I make a strawberry blueberry smoothie thicker?
The most effective way to thicken a strawberry blueberry smoothie is to use frozen fruit instead of fresh. If it's still thin after blending, add 2 tablespoons of rolled oats or 170g of Greek yogurt and blend again for body. A tablespoon of chia seeds also thickens it, though it takes a few minutes to gel. Avoid adding more frozen fruit without more liquid, or you'll stall the blender.
Can I make a strawberry blueberry smoothie ahead of time?
You can make a strawberry blueberry smoothie ahead of time and keep it in a sealed jar in the fridge for up to 24 hours. Some separation is normal by morning, so a quick shake or stir brings it back, and a squeeze of lemon juice keeps the color bright. For longer storage, freeze it in portions for up to 3 months and thaw overnight. If you prep often, portioning the fruit into freezer bags is more practical than storing the finished drink.
