Ready to beat the heat? This keto-friendly Cucumber Cooler recipe is your new go-to summer drink. It’s super easy to whip up, requires just a few ingredients, and gives you a perfectly refreshing sip in no time. Light, hydrating, and oh-so-tasty, it’s just what you need to cool down and chill out!

Two glasses of iced cucumber cooler drinks garnished with lime wedges and mint leaves on a white cloth, with sliced limes and mint leaves scattered around.

This Cucumber Mint Cooler recipe is designed for simplicity and flavor. Blending fresh cucumbers with mint and lime creates a refreshing base, which is then lightly sweetened and topped with soda water for a fizzy lift. My personal experiments led to using powdered erythritol as a sugar-free sweetener, balancing health with just the right touch of sweetness, making this cucumber drink not only refreshing but guilt-free too!

🗝️ Key ingredients & substitutions

Ingredients for a refreshing cucumber cooler on a wooden board: a cucumber, a bowl of lime juice, a small bowl of powdered sweetener or sugar, and a bunch of mint leaves. Club soda not pictured.
  • Cucumber: Adds a fresh, clean taste. English cucumber is preferred for its fewer seeds and smoother flavor, but any type will do.
  • Lime: Provides a tangy kick that balances the sweetness. Lemon juice can be a good substitute if limes are not available.
  • Fresh mint: Brings a burst of coolness. If mint is too strong for you, try basil for a milder but still aromatic alternative.
  • Club soda: Adds the fizz that lifts the drink. Tonic water can be used for a slightly sweeter taste.
  • Sugar or sweetener: I used powdered erythritol to keep it healthier, but you can use regular sugar, honey, or agave nectar depending on your preference. Keto simple syrup is also great in this recipe.

🥣 How to make a cucumber cooler mocktail

  1. Prepare your cucumber: Chop the cucumber into one-inch pieces to ensure it blends smoothly.

  3. Blend until smooth: Blend the mixture until everything is thoroughly pureed and the sweetener is well dissolved.

🪄 Recipe notes & tips

  • Cucumber choice: Using English cucumbers is best as they are less bitter and have fewer seeds, but regular cucumbers work well too; just make sure to peel them first.
  • Sweetener adjustments: Start with a small amount of sweetener and adjust according to your taste. Remember, you can always add more, but you can’t take it out!
  • Straining the mix: For a smoother drink, ensure to strain thoroughly. If you prefer a bit more texture, a less fine mesh can be used.
  • Serving size: This recipe makes enough for two generous servings. If you’re hosting a party, simply multiply the ingredients and add them to a big pitcher.

✨ Variations

  • Cucumber cooler cocktail: Add a splash of gin or cucumber vodka for an adult version of this refreshing drink.
  • Herbal notes: Experiment with different herbs like basil or rosemary if mint isn’t your favorite.
  • Fruit infusions: Throw in some strawberries or raspberries in the blender for a fruity variation.
  • Sparkling mineral: Use sparkling mineral water instead of soda water for a different kind of fizz.
  • Tropical vibes: Add a splash of coconut water for a tropical twist, enhancing the hydrating qualities.
  • Citrus change: Swap out the lime for lemon, orange, or grapefruit, or use a mix for a more complex citrus flavor.

🫙 Storage instructions

  • Refrigerate immediately: Pour any leftover cucumber mint cooler into a sealed container and keep it in the refrigerator.
  • Shelf life: It’s best consumed within 24-48 hours to enjoy its freshest taste and vibrant flavors.
  • Avoid freezing: Freezing can alter the texture and flavor, so it’s best to make it fresh and drink it while it’s cold and refreshing.
  • Stir before serving: If the mixture separates in the fridge, just give it a good stir or shake before serving to redistribute the flavors.

🍽️ How to serve

  • Light snacks: Enjoy this cooler with keto-friendly dips like guacamole, ranch, or a cream cheese-based dip served with cucumber slices or celery sticks instead of chips.
  • Barbecue favorites: The freshness of the cucumber mint cooler complements grilled meats and veggies perfectly.
  • Seafood dishes: It goes great with seafood, especially grilled shrimp or a light fish ceviche.
  • Salads: Serve with a pickled beet salad or fruit salad for a refreshing meal during hot weather.
  • Desserts: Finish with a light dessert, such as sorbet or keto lemon jello, to keep the meal refreshing from start to finish.

❓ Frequently asked questions

Can I make this cucumber mint cooler ahead of time?

Yes, you can prepare the cucumber mixture a day in advance and store it in the refrigerator. Just add soda water and ice before serving to maintain the fizz and freshness.

Can I use bottled lime juice instead of fresh?

Fresh lime juice is best for flavor, but if you’re in a pinch, bottled lime juice can work. Just be aware it might slightly alter the taste.

What’s the best way to garnish this drink?

A slice of cucumber, a sprig of mint, or a wedge of lime are all great choices that add a touch of elegance and extra flavor.
