Thai iced tea is a sweet, creamy, and refreshing drink that has become a favorite at Thai restaurants across the United States. Its beautiful orange color, strong tea flavor, and creamy finish make it especially satisfying on a hot afternoon.
The good news is that you don’t need to visit a restaurant to enjoy it. With a few simple ingredients and about 15 minutes of active preparation, you can make Thai iced tea at home.
This Thai Iced Tea Recipe creates a balanced drink with bold black tea, warm spices, sweetness, and creamy evaporated milk. You can also adjust the sweetness and creaminess to match your taste.
What Is Thai Iced Tea?
Thai iced tea, often called “cha yen,” is a chilled tea drink traditionally made with strong black tea, sugar, and a creamy dairy component. It is served over plenty of ice and is commonly enjoyed alongside Thai food.
Many American Thai restaurants prepare the drink using a Thai tea blend that may contain black tea and spices such as star anise, tamarind, cardamom, or vanilla flavoring. The exact blend varies, so homemade Thai iced tea can taste slightly different depending on the tea you use.
The classic orange color comes from the tea blend and, in some commercial mixes, added coloring.

Choosing the Right Thai Tea
For the most recognizable restaurant-style flavor, use a packaged Thai tea mix. Thai tea mixes are widely available at Asian grocery stores and online.
If you cannot find Thai tea mix, you can use a strong black tea such as Assam. However, the flavor and color will not be exactly the same because traditional Thai tea blends often contain additional spices and flavorings.
How to Make Thai Iced Tea Step by Step
Step 1: Bring the Water to a Boil
Pour 4 cups of water into a medium saucepan and bring it to a boil over medium-high heat.
Once the water reaches a full boil, reduce the heat slightly. You want the water hot enough to extract the tea but don’t need to maintain an aggressive boil.
Step 2: Add the Thai Tea
Add 4 tablespoons of Thai tea mix to the hot water.
Stir gently to make sure all of the tea is submerged.
Let the tea steep for approximately 5 minutes. If you prefer a stronger tea flavor, you can steep it for up to 7 minutes.
Avoid steeping for too long because very strong black tea can develop a bitter taste.
Step 3: Strain the Tea
Place a fine-mesh strainer over a large heatproof pitcher or bowl.
Slowly pour the brewed tea through the strainer to remove the loose tea leaves and spices.
If your Thai tea mix is very fine, you may want to use a coffee filter or tea filter in addition to the strainer.
At this point, the tea should have a strong aroma and a deep orange-brown color.
Step 4: Sweeten While the Tea Is Hot
While the tea is still warm, add 4 tablespoons of granulated sugar.
Stir until the sugar completely dissolves.
Adding the sugar while the tea is hot is important because it allows the sugar to dissolve evenly.
Taste carefully once it has cooled slightly. If you prefer a sweeter Thai iced tea, add another tablespoon of sugar.
Step 5: Let the Tea Cool
Allow the sweetened tea to cool at room temperature for about 15–20 minutes.
For faster cooling, place the pitcher in the refrigerator once it is no longer steaming hot.
You can also prepare the tea several hours ahead and refrigerate it until you’re ready to serve.
Step 6: Prepare Your Glasses
Fill four tall glasses generously with ice.
Use plenty of ice because Thai iced tea is traditionally served very cold.
If you’re making the drink for a party, you can prepare the tea base ahead of time and assemble each glass just before serving.
Step 7: Pour in the Tea
Pour the chilled Thai tea over the ice, leaving some space at the top of each glass for the milk.
The tea should fill approximately three-quarters of the glass.
Step 8: Add the Creamy Milk
Slowly pour about 2 tablespoons of evaporated milk over each glass.
Then add a small splash of half-and-half or heavy cream.
Pouring the milk slowly creates the beautiful layered appearance commonly associated with Thai iced tea.
If you want a sweeter and richer drink, drizzle a little sweetened condensed milk into the glass.
Step 9: Stir and Serve
Give the drink a gentle stir before drinking so the creamy milk blends with the sweet tea.
Serve immediately while it is cold and refreshing.
For a restaurant-style presentation, leave a little of the creamy layer visible near the top instead of mixing it completely.

Tips for the Best Thai Iced Tea
Use Strong Tea
Thai iced tea is served over ice, so the tea needs to be strong enough to maintain its flavor after the ice begins melting.
A weak tea can taste watery and bland.
Don’t Over-Steep
More steeping time doesn’t always mean better tea. Over-steeping black tea can create bitterness.
Start with about 5 minutes and adjust from there based on your preferred strength.
Sweeten Before Chilling
Sugar dissolves much more easily in hot tea than cold tea.
For the smoothest drink, sweeten the tea immediately after brewing.
Chill the Tea Before Serving
Pouring hot tea directly over ice can quickly melt the ice and dilute your drink.
Whenever possible, cool the tea first and then pour it over fresh ice.
Adjust the Creaminess
There is no single required amount of milk for homemade Thai iced tea.
For a lighter drink, use evaporated milk.
For something richer, add half-and-half or heavy cream.
For an extra-sweet dessert-style version, add a small amount of sweetened condensed milk.
Can You Make Thai Iced Tea Ahead of Time?
Yes. Thai iced tea is excellent for making ahead.
Prepare the tea, strain it, sweeten it, and allow it to cool. Store the tea base in a covered container in the refrigerator for up to several days.
Keep the milk separate until you’re ready to serve. This makes it easier to adjust the creaminess of each glass and keeps the tea base fresh and versatile.
When serving, simply fill a glass with ice, pour in the chilled tea, and add your preferred amount of milk.
How to Make Thai Iced Tea Less Sweet
Traditional Thai iced tea is quite sweet, but you can easily reduce the sugar at home.
Start with 2 tablespoons of sugar instead of 4. Taste the tea after it has cooled and add more if needed.
Remember that milk can also contribute sweetness, particularly if you’re using sweetened condensed milk.
For a more balanced everyday drink, using less sugar and unsweetened evaporated milk is a simple option.
How to Make It Dairy-Free
You can make a dairy-free version by replacing the evaporated milk and cream with a plant-based alternative.
Unsweetened coconut milk works especially well because its creamy texture complements the tea’s warm, spiced flavor.
You can also try oat milk or soy milk.
If you’re using a sweetened plant-based milk, reduce the added sugar so the final drink doesn’t become overly sweet.
How to Make Thai Iced Tea Without Thai Tea Mix
If Thai tea mix isn’t available, you can make a simplified version using strong black tea.
Use 4 tablespoons of loose-leaf Assam tea for 4 cups of water. You can add a small amount of ground cardamom, star anise, or vanilla for a more complex flavor.
Steep the tea for about 4–5 minutes, strain it thoroughly, and sweeten while warm.
Keep in mind that this version will not taste exactly like Thai restaurant tea, but it can still make a delicious iced tea.
Common Mistakes to Avoid
Using Too Little Tea
Because the drink is served over ice and combined with milk, weak tea can disappear beneath the other flavors.
Use a generous amount of tea to create a strong base.
Adding Cold Sugar
Sugar doesn’t dissolve efficiently in cold tea. Always sweeten the tea while it is warm.
Skipping the Straining Step
Tiny tea leaves and spices can make the drink unpleasantly gritty. Strain the tea carefully before chilling.
Using Too Much Milk
Milk should complement the tea rather than completely hide its flavor.
Start with a small amount and add more until you reach your preferred balance.
Serving With Too Little Ice
Thai iced tea is meant to be cold and refreshing. Fill your glass generously with ice for the best experience.
What to Serve With Thai Iced Tea
Thai iced tea is especially good with spicy and savory dishes.
Try serving it with:
- Pad Thai
- Thai green curry
- Thai red curry
- Chicken satay
- Thai basil chicken
- Fresh spring rolls
- Crispy egg rolls
- Drunken noodles
- Thai fried rice
The sweetness and creaminess of the tea can help balance spicy dishes, making it a natural companion to a Thai-inspired meal.
