The key to making this drink delicious is to be patient. After you brew the Thai tea mix, make sure to allow it to cool completely or have it chilled. That way it doesn’t melt the ice and you get all the flavors.

How to Make Keto Thai Iced Tea: Sugar Free

  • We have some recommended Thai tea mixes that taste just like what you order at restaurants.
  • You can use sugar free or keto friendly sugar substitutes like: monk fruit with erythritol, stevia, Sucralose (Splenda). Make sure you check the your specific package for sugar substitute amounts, as they will all vary, even between the same kinds of sweetener and sometime between a brands own products. This recipe is based off the equivalent to 3/4 cup of sugar.
  • Customize your sweetness. After you brew your first batch, you’ll know if you want it make it less sweet or more sweet.
  • Allow the brewed tea to completely cool so that it doesn’t melt the ice and dilute the flavors. You can even make it overnight or several days ahead and leave chilled in the fridge.
  • Add your favorite unsweetened creamer like: half and half, milk or even coconut milk if you like those flavors.

  • Strain the tea leaves (we love using these reusable cloth filters). Set finished Thai tea aside to cool completely. You can make this ahead of time and have the Thai tea chilling in the fridge. We usually like to make this tea mix one day ahead.

  • Fill glasses with ice and pour in Thai tea leaving enough room to fill in your half and half (or other creamer). For an 12 oz. glass filled with ice cubed, we like to add about 2-3 tablespoons of half and half for a creamier flavor.
