I’ve been all about the cold and refreshing keto drinks lately. In the past month alone, I’ve shared recipes for keto frappuccinos and sugar free Brazilian lemonade. And now I’m offering up this delicious keto sweet tea.

What gives? Well it’s summer and it’s hot out. Really, really, REALLY hot out. Much of the North American continent is experiencing record-breaking heat waves.

And not all of us are fortunate enough to have central AC. So when you need a little relief from the heat, ice cold drinks are a necessity.

Keto Sweet Peach Tea to the rescue!

What is sweet tea?

I was not at all familiar with this southern favorite until a few years ago. I’m not a huge ice tea drinker so it simply wasn’t on my radar.

But once I tried it, I quickly saw the appeal. It’s just as it sounds: very sweet iced tea, and it’s usually made in large batches. It’s meant to be ready in the fridge, to offer any visitors who might drop by on a hot day. Southern hospitality at its finest!

Sometimes it’s plain tea, but it can also contain mint, lemons, or other flavors. After spotting a recipe for sweet peach tea on Diary of a Real Housewife, I knew I wanted to create a keto version.

But peaches aren’t keto!

Admittedly, peaches are not the lowest carb fruit out there. But they also aren’t as high carb as you might think. I wrote more extensively about that in my keto peach ice cream, so check that out if you want to dig into the nutrition facts.

For this keto sweet tea recipe, you create a syrup by boiling and steeping a small amount of peaches to release their flavor. You also discard the majority of the peach pulp (I actually turned mine into popsicles for my kids), which lowers the carb count further.

However, it is hard get an exact carb count for this recipe because there’s no way to measure exactly how many of the carbs transfer to the syrup. So I took a conservative estimate that about two thirds of the calories and carbs make their way into the sweet tea.

I also estimated that none of the fiber ends up in the tea, since the pulp is discarded. The final carb count ends up at 3.6g total carbs per serving.

On a blazing hot summer day, I’d say that’s keto enough for me!

How to make peach keto sweet tea


  • Fresh peaches
  • Water
  • Sweetener (I recommend using some allulose or BochaSweet to avoid re-crystallization)
  • Black tea bags


  1. Make the peach simple syrup. Bring to a simmer with water and the sweeteners and cook until the peaches are soft. Let them steep and continue to infuse the syrup for another 10 minutes.
  2. Mash the peaches. You want them to release as much juice as possible. I used a small avocado masher for this but a wooden spoon would also work.
  3. Strain the syrup to remove all the pulp.
  4. Steep the tea. Boil the remaining water and add the tea bags. I don’t recommend steeping for more than 5 minutes, as it can become bitter if left longer.
  5. Combine the syrup and tea.
  6. Pour over ice and enjoy!

Frequently Asked Questions

How can this be keto when it contains peaches?

Please see the above section labeled “But peaches aren’t keto!”. At only 3.6g of carbs per glass, I stand by my statement that this is a lovely and refreshing keto beverage.

What if I just want plain sweet tea?

No problem. Don’t make any syrup, simply stir the sweetener into the tea when it’s still warm, until dissolved.

Can I use a different fruit?

Certainly. I suggest raspberries for a delicious twist. You could also simply add lemons to some sugar-free sweet tea, without making a simple syrup.

What sweeteners work best for keto sweet tea?

I like a combination of Swerve and allulose, as it makes the peach mixture more syrupy. I don’t recommend using erythritol based sweeteners alone, as they tend to settle out of the liquids. However, you can use allulose or BochaSweet on their own.

What if I want it less sweet/more sweet?

If it’s too sweet for your taste, add a little more water or steep another tea bag and add the cooled tea. Adding more sweetener is easy, just stir it into the finished sweet tea.

Can I use peach extract or flavor in place of the peach syrup?

Sure! In that case, I recommend making plain sweet tea and simply adding the extract or flavoring to taste.
