The ingredients for this Thai Iced Tea (Cha Yen) Recipe are straightforward but essential — each contributes to the authentic flavor, rich texture, and vibrant color that make this drink so irresistible.

¾ cup Thai tea leaves: The heart of the recipe, these loose tea leaves provide the signature deep amber color and unique aroma.
4 cups hot off-the-boil water: Perfect temperature to steep the tea leaves and extract all the flavor.
¼ cup sugar: Adds balanced sweetness that complements the tea’s spice.
⅛ teaspoon salt: A pinch enhances and rounds out the flavors beautifully.
1 ½ tablespoons sweetened condensed milk: Gives the tea its creamy, luscious mouthfeel and signature sweetness.
A pint glass packed full of ice: Keeps your drink chilled and refreshing.
2-3 tablespoons evaporated milk: Adds a velvety finish when drizzled on top.
Additional sugar (1 tablespoon) and half and half (3-4 tablespoons) for variation: For making an American style Thai iced tea if you prefer a richer, creamier option.

Directions

Step 1: Start by making the Thai tea base. Steep ¾ cup of Thai tea leaves in 4 cups of hot off-the-boil water for 5 minutes. I find that using a French press makes straining the tea super easy and less messy.

Step 2: After steeping, strain the tea leaves through a fine mesh strainer to get a clear, bright amber tea. Then stir in ¼ cup sugar and ⅛ teaspoon salt until fully dissolved. Let the tea base cool to room temperature before proceeding so it doesn’t melt your ice too quickly.

Step 3: You can store this tea base in your fridge for up to two weeks, which I love because it means I can whip up a glass of tea any time without starting from scratch.

Step 4: For the classic Thai style tea, pour ¾ cup of the tea base into a mixing glass. Stir in 1 ½ tablespoons of sweetened condensed milk until the mixture is smooth and creamy. If the tea base is cold, I usually microwave it briefly to bring it to room temperature to help the condensed milk dissolve.

Step 5: Fill a pint glass with plenty of ice. Pour the tea and condensed milk mixture over the ice, then finish by drizzling 2-3 tablespoons of evaporated milk on top. The layers make it visually stunning and taste heavenly.

Step 6: If you want to try the American style, pour the tea base into a glass, stir in an extra tablespoon of sugar if you like it sweeter, then pour over ice and drizzle with 3-4 tablespoons of half and half for a richer, creamier texture.

Servings and Timing

This recipe makes 4 servings of Thai Iced Tea, perfect to share or save for a few days. Prep time is about 10 minutes, mostly to steep the tea leaves thoroughly. The cook time is minimal since steeping is the main step—about 5 minutes. Total time from start to finish, including cooling, is around 15 minutes. Keep in mind you’ll want to let the tea base cool fully before making individual drinks to keep your iced tea crisp and refreshing.

When serving this Thai Iced Tea (Cha Yen) Recipe, I like to pair it with some light, flavorful Thai snacks or desserts. Think crispy spring rolls, fresh mango sticky rice, or savory satay skewers. The creamy, sweet tea perfectly balances salty and spicy flavors and adds a refreshing finish to the meal.

Presentation-wise, I love using clear glasses to showcase the beautiful gradient of the tea with the milk swirling on top. For a little extra flair, garnish with a sprig of mint or a small edible flower. This drink is best served chilled, packed with ice to keep it crisp and cold — it’s a total treat on a warm day or even as a cool contrast during a cozy evening indoors.

This recipe works beautifully for family dinners, casual get-togethers, or festive celebrations like Thai New Year or summer parties. The portion size is just right at about 12 ounces per glass, leaving everyone feeling refreshed and satisfied without being too heavy.

Variations

I like to switch things up sometimes with this Thai Iced Tea (Cha Yen) Recipe. If you prefer it vegan, simply swap the sweetened condensed milk and evaporated milk with coconut milk or your favorite dairy-free creamers—this adds a lovely tropical twist that pairs wonderfully with the tea spices. For those watching sugar intake, I recommend using coconut sugar or monk fruit sweetener instead of white sugar; it changes the flavor subtly but still keeps the drink delicious.

Some days I add a pinch of star anise or cardamom while steeping the tea leaves to deepen the spice profile. Others, I make the American style with half and half instead of evaporated milk for a richer, creamier experience — it almost feels like a dessert in a glass! I’ve also experimented with brewing the tea in a cold brew method overnight for a much smoother and less bitter base, perfect if you want to prepare everything ahead for a party.

Storage and Reheating

Storing Leftovers

I store any leftover Thai tea base in an airtight container, like a glass jar or bottle, in the fridge. It keeps nicely for up to two weeks, which is super convenient if you want to enjoy multiple servings throughout the week. Just give it a good stir or gentle shake before using again since some ingredients may settle.

Freezing

Freezing this tea base isn’t something I usually do because the texture of the milk components can change once thawed, sometimes becoming grainy. If you want to freeze it, I recommend freezing only the plain brewed tea without sugar or milk. That way, you can thaw and sweeten fresh each time. Keep frozen tea for up to one month and thaw overnight in the fridge.

Reheating

If you want to enjoy the tea warm, I suggest gently warming just the tea base in a saucepan over low heat—avoid boiling it again as it can become bitter. Add the condensed milk or evaporated milk after warming and stir well. Heating the tea when already mixed with ice is not recommended, as it can affect texture and flavor balance.

FAQs

What kind of tea leaves should I use for authentic Thai iced tea?

For an authentic Thai Iced Tea (Cha Yen) Recipe, you want to use specific Thai tea leaves, which are usually strong black teas blended with spices and sometimes orange blossom for aroma. You can find these online or at Asian grocery stores. Don’t substitute with regular black tea as it won’t provide the same distinctive flavor and color.

Can I make this drink vegan?

Absolutely! Just swap the sweetened condensed milk and evaporated milk with coconut condensed milk or coconut cream, and use a plant-based milk like oat or almond milk for the drizzle on top. It’s delicious and keeps that creamy texture you love.

How sweet is this drink? Can I adjust the sugar?

This recipe strikes a nice balance of sweetness but you can definitely adjust it to your personal taste. If you want it less sweet, start by cutting the sugar by half, then add more as needed. Remember the condensed milk adds sweetness too, so taste as you go!

What’s the difference between Thai style and American style Thai iced tea?

In the Thai style, the tea is sweetened with sweetened condensed milk and topped with evaporated milk, giving it a slightly lighter creaminess and smokiness. The American style uses granulated sugar and half and half or cream, resulting in a richer, thicker drink that’s a bit sweeter and less traditional but very tasty.

Can I prepare the tea base in advance?

Yes! Making the tea base ahead saves a lot of time and is one of my favorite tips. Just store the prepared base in an airtight container in the fridge, and it will keep for up to two weeks. This way, you can quickly mix individual drinks anytime you want.

Conclusion

I can’t recommend this Thai Iced Tea (Cha Yen) Recipe enough—it’s such a comforting, flavorful drink that brings a touch of Thai culture right to your home. The beautiful color, the delicate balance of sweetness and spice, and the creamy finish make it an absolute favorite of mine. I hope you enjoy making and sipping it as much as I do. Cheers to adding a little exotic delight to your day!
