Costco Frozen Strawberry Lemonade Recipe – Easy 5-Minute Copycat

If you’ve ever strolled through Costco’s frozen food section during summer, you might’ve noticed their refreshing Frozen Strawberry Lemonade. 

It’s not just a cold drink; it’s a flavor-packed, icy lemonade blended with sweet strawberries.

I recently made this Costco Frozen Strawberry Lemonade recipe, and I liked its slushy texture.

 

How to Make Costco Frozen Strawberry Lemonade

Costco Frozen Strawberry Lemonade is a sweet and tangy frozen beverage made with frozen strawberries, lemonade base, ice, and honey. It’s bright, citrusy, and fruity.

Ingredients:

• 1 ½ cups fresh strawberries: You can use hulled or frozen strawberries, too.
• 1 cup lemonade concentrate: You can use store-bought, but homemade is better.
• 2 cups ice cubes
• 1 tablespoon honey or sugar: adjust it based on your taste.
• 1 tablespoon lemon juice: For extra tang.
• ½ cup cold water: Sparkling water is also good if you want fizz.
• Lemon slices & strawberry halves (for garnish, optional)

Tip: If you love layering flavor, you can drizzle a little Torani Blue Raspberry Syrup inside the glass. It will give a colorful twist; do it before pouring in your lemonade slush.

Instructions:

1. Prepare Strawberries: Wash and hull strawberries. If you’re using frozen strawberries, keep them at room temperature for 5 minutes so they can blend easily.
2. Blend the Base: In a blender, add all ingredients that I mentioned above, such as strawberries, lemonade concentrate, ice cubes, honey, lemon juice, and cold water. Blend it on a high speed for up to 30 seconds. Or until you see all ingredients are blended completely.
3. Taste and Adjust: Taste the mixture. If it is too tart, add a little more honey. If it’s too sweet, squeeze more lemon juice.
4. Serve Immediately: Pour that slushy mixture into chilled glasses. Garnish it with a lemon slice and a strawberry half. Serve with a straw (because it’s thick and icy!).

Ingredient Substitutes:

• Strawberries: You can use frozen strawberries, but fresh ones taste more vibrant. If strawberries aren’t in season, you can swap them with raspberries or even mango chunks.
• Lemonade Concentrate: If you don’t have it. You can make an alternative. You’ve to use 1 cup of fresh lemon juice and mix it with ½ cup sugar and 1 ½ cups water.
• Honey/Sugar: You can use maple syrup or agave if you want a lighter sweetness.
• Water: For a fruity touch, you can try sparkling coconut water (like I did in my Sparkling Coconut Water Recipe).

 

Tips for Perfect Frozen Strawberry Lemonade

• Use Crushed Ice Instead of Whole Cubes: It will blend too fast and give a smoother texture to your drink.
• Balance Sweet and Tart: Costco’s version isn’t overly sweet. Instead, it’s citrusy zing that makes it stand out. So, always taste-test before serving.
• Chill Your Glasses: You have to keep your serving glasses in the freezer for at least 10 minutes. By doing so, your Frozen Strawberry Lemonade drink will remain cold for a longer time.
• Add Layers: Simply pour some strawberry puree at the bottom. And, at the top, add some frozen lemonade. It’s a fun presentation.
• Upgrade with Fresh Mint: Muddle 2 to 3 mint leaves if you want a cooling summer vibe.

 

What to Serve With Frozen Strawberry Lemonade

Summer Snacks

• Fresh Fruit Skewers: I personally like watermelon, pineapple, and berries.
• Mini Cheese Boards: You can pair this citrus drink with soft cheeses like brie or Havarti, which is amazing.
• Homemade Soft Pretzels: You will like the saltiness that will cut through the sweetness.

Sweet Treats

• Luxury Chocolate Covered Strawberries: it’s a perfect fruity-chocolate combo with this chilled lemonade.
• Crumbl Semi-Sweet Chocolate Chip Cookies: They are soft, rich cookies, and they pair really well with tart lemonade.
• Lemon Bars or Shortbread: The buttery base and citrus topping taste good.

Savory Bites

• Chicken Salad Wraps: It’s light and protein-packed.
• Shrimp Tacos: Add a drizzle of citrus crema. The tang will complement this lemonade very well. 
• Caprese Skewers: Tomato, mozzarella, basil, and a drizzle of balsamic go well with the drink’s acidity.

For Brunch Vibes

• Mini Waffles or Pancakes: You can try my Tropical Smoothie Mango Monsoon Recipe, and with this lemonade drink. You will have a fruity brunch spread.
• Berry Yogurt Parfaits: You have to layer strawberries, granola, and Greek yogurt. It’s simple but filling.

 

Variations to Try

1. Iced Strawberry Lemonade (Non-Frozen Version)

If you don’t want it icy, skip the blender and simply stir together 1 cup lemonade + ½ cup strawberry puree over ice. Easy and equally refreshing.

2. Costco Copycat “Strawberry Lemonade Slush Float”

Layer the frozen strawberry lemonade with a scoop of vanilla ice cream or lemon sorbet. 

It turns it into a dessert drink — kids absolutely love this one.

3. Sugar-Free or Keto-Friendly Version

You have to replace sugar or honey here with monk fruit sweetener. 

And don’t use lemonade concentrate; instead, mix lemon juice with sparkling water.

4. Strawberry Coconut Lemonade

Blend in ¼ cup of coconut milk for a creamy tropical taste.

How to Store Leftover Strawberry Lemonade

You can store any leftovers in an airtight mason jar in the freezer for up to 2 days. 

When ready to drink, leave it out for 10–15 minutes to soften, then stir or re-blend quickly to restore the slushy consistency.

If you’ve added alcohol, it’ll stay slushy longer because alcohol lowers the freezing point — fun fact!

 

Pro Serving Ideas

• For Parties: Serve in mason jars or clear Costco-style tumblers with a sugar rim and lemon slice.
• For Kids: You have to add paper umbrellas to make your lemonade feel like a mocktail, but kid-friendly.
• For Adults: Top your drink with a little sparkling wine.

 

Conclusion

That’s it, your Costco Frozen Strawberry Lemonade — thick, icy, tangy, and just sweet enough to make every sip feel like summer. It’s one of those drinks that look fancy but takes literally 5 minutes to make. 

I love how flexible it is, too; you can make it sweeter, more tart, or even turn it boozy for parties. If you’re hosting, just double the batch and keep it in the freezer; it’ll stay slushy and perfect. 

Homemade always tastes fresher than the store version, and once you make this, you won’t want to buy the Costco one again.

 

FAQs

Can I use fresh strawberries instead of frozen?

Yes, you can use fresh strawberries. However, make sure to freeze them for a few hours first. 

Fresh strawberries without freezing will make your drink too thin and watery. 

Frozen strawberries will give a thick, icy texture like Costco’s version.

How do I make it less sweet like the real Costco one?

Start with less honey or sugar, blend, taste, and adjust. 

The key is keeping the lemon flavor strong — that’s what gives it that signature Costco tang instead of a sugary drink.

Can I store leftover strawberry lemonade for later?

You can. Pour it into a mason jar or airtight container, freeze for up to 2 days, and thaw for 10–15 minutes before serving. 

Re-blend or stir it to bring back that slushy texture.
