WHY IT WORKS

Why This Recipe Works

01

Berry Flavor Without Banana

A modest portion of frozen mixed berries gives the smoothie a bright berry flavor and thick texture without relying on banana or fruit juice.

02

Creamy, Not Watery

Plain Greek yogurt adds body and creaminess, while unsweetened almond milk keeps the smoothie easy to blend and drink.

03

Chia Adds Body

Chia seeds help thicken the smoothie slightly while adding fiber without competing with the berry flavor.

Recipe Notes

Ingredient Notes

Use frozen mixed berries with no added sugar or syrup. A blend containing raspberries, blueberries and blackberries gives a deep berry color and balanced tart-sweet flavor. Choose plain Greek yogurt and unsweetened almond milk so added sugars do not raise the carbohydrate content unnecessarily.

Useful Substitutions

Fresh mixed berries can replace frozen berries, although the smoothie will be thinner; add a little ice if desired. Plain skyr can replace Greek yogurt for a similarly thick texture. Unsweetened soy milk can replace almond milk if you prefer a different plant milk.

INGREDIENT QUALITY

Quality Note

Use unsweetened frozen berries that are loose rather than heavily frosted into one solid block. They blend more evenly and make it easier to control the final texture.

SPEND LESS

Cost-Saving Tip

A larger bag of frozen mixed berries can reduce waste because you can measure only what you need and keep the rest frozen for later smoothies.

COOKING TIPS

Tips

Add the Liquid First

Putting the almond milk and yogurt in the blender before the frozen berries helps the blades catch and circulate the mixture more easily.

Use Unsweetened Ingredients

Check the berry, yogurt and almond-milk labels for added sugars if keeping the smoothie lower in carbohydrates is important to you.

Adjust the Thickness

If the smoothie is thicker than you like, blend in a small splash of unsweetened almond milk. If it is too thin, add a few more frozen berries or let the chia stand briefly before drinking.

Blend Until Completely Smooth

Chia seeds and berry seeds can leave a coarse texture if the smoothie is under-blended, so keep blending until the drink looks even and creamy.

MAKE IT LAST

Storing, Freezing & Reheating

Storing

For the best texture, drink the smoothie immediately. If needed, refrigerate it in a tightly covered container for up to 24 hours and stir or shake well before drinking.

Freezing

You can freeze leftover smoothie in an ice-cube tray for up to 1 month. Reblend the frozen cubes with a small splash of unsweetened almond milk when ready to use.

QUESTIONS

Low-Carb Antioxidant Berry Smoothie FAQs

Can I make this berry smoothie with fresh berries?

Yes. Fresh berries work, but the smoothie will be less thick and cold than one made with frozen berries. Add a little ice if you want a frostier texture.

Which berries work best in an antioxidant berry smoothie?

A mix of raspberries, blueberries and blackberries gives a deep color and balanced berry flavor. Strawberries can also be included in the mix.

What keeps this berry smoothie lower in carbohydrates?

This version uses a modest amount of berries, plain Greek yogurt and unsweetened almond milk, with no banana, fruit juice or added sugar. Exact carbohydrate content varies with the products you use.

Can I make this smoothie dairy-free or vegan?

Yes. Replace the Greek yogurt with an unsweetened plant-based Greek-style yogurt. The remaining ingredients in the base recipe are already dairy-free and plant-based.

Can I make the smoothie ahead of time?

It is best immediately after blending, but you can refrigerate it for up to 24 hours. The chia will continue to thicken the smoothie, so stir or shake it well before drinking.
