• 8–10 large leaves fresh basil leaves (plus more for garnish)
• ½ cup granulated sugar (for simple syrup)
• ½ cup water (for simple syrup)

• 1 cup cold water (to thin the blend)
• 2 cups ice (for slushie texture)

Equipment

• Blender (high-speed works best)
• Small saucepan
• Fine-mesh strainer (optional)

How to Make Strawberry Basil Lemonade

Step 1 — Make basil simple syrup (5 minutes)

Combine the sugar and ½ cup water in a small saucepan over medium heat. Stir until the sugar dissolves — about 2 minutes. Remove from heat, add the basil leaves, and let steep for 10 minutes while you prep everything else. The heat extracts the basil’s essential oils without making it taste cooked. Strain out the basil and let the syrup cool to room temperature. You can make this a day ahead and refrigerate it.

Step 2 — Blend everything together (2 minutes)

Add the strawberries, basil syrup, lemon juice, cold water, and ice to a blender. Blend on high for 60 to 90 seconds until completely smooth and slushie-thick. Taste — if it’s too tart, add a tablespoon of sugar. Too sweet, a squeeze of lemon. If it’s too thick to pour, add ¼ cup more water and pulse.

Step 3 — Serve immediately (1 minute)

Pour into tall glasses. Garnish with a fresh basil leaf and a strawberry half on the rim. Serve with straws or spoons — this is thick enough to need both. If you want it even frostier, pop the glasses in the freezer for 5 minutes before serving.

Pro Tips

Use ripe, in-season strawberries. This drink is only as good as your berries. If strawberries aren’t in season, frozen work just as well — thaw them first and reduce the ice to 1 cup.

Don’t skip the steeping step. Tossing raw basil into the blender gives you green flecks and a grassy taste. Steeping in hot syrup extracts the sweet, anise-like flavor without the bitterness.

Chill your glasses. A frosty glass keeps the slushie from melting the first time you pour it. Five minutes in the freezer does the trick.

Freeze strawberries when they’re on sale. Hull them, spread on a parchment-lined sheet pan, freeze solid, then transfer to a zip-top bag. You’ll have perfect frozen strawberries for slushies all year long.

Make it a party punch. Multiply the recipe by 4, blend in batches, and pour into a punch bowl. Float fresh strawberry slices and basil leaves on top. Add a bottle of prosecco for a slushie cocktail that serves 12.

Taste your strawberries before blending. If they’re very sweet, you may not need all the sugar in the syrup. If they’re tart, add an extra tablespoon. The sweetness of the final slushie depends entirely on the berries.

Use frozen fruit for a thicker slushie. If your strawberries are fresh (not frozen), add an extra cup of ice. If they’re frozen, you can reduce the ice to 1 cup. The ratio of frozen-to-fresh fruit determines the final texture.

Variations & Substitutions

Strawberry basil margarita

Add 2 oz of tequila and 1 oz of triple sec per serving. Rim the glass with Tajín for a spicy-sour kick.

Lavender strawberry version

Replace the basil with 1 tablespoon of dried culinary lavender in the syrup. Strain carefully — too much lavender tastes like soap.

Dairy-free creamy version

Add ½ cup of full-fat coconut milk to the blender. It turns the slushie into a creamy, milkshake-like treat.

Storage & Reheating

Best served immediately. Slushies don’t hold their texture — they either melt or freeze solid.

Make-ahead option: Freeze the blended mixture in an ice cube tray, then re-blend the cubes when you’re ready to serve. This actually gives you a better texture than trying to refrigerate a batch.

Syrup keeps for 2 weeks in the fridge — make a double batch and you’re ready for slushie emergencies.

Frequently Asked Questions

Can I use frozen strawberries?

Yes. Thaw them first and reduce the ice to 1 cup since the frozen berries already add cold and thickness. The flavor is very similar to fresh.

I don't like basil. Can I leave it out?

You can, but you’ll lose the complexity that makes this more than just strawberry lemonade. If you want a different herb, mint works beautifully — steep it the same way.

How do I make this into a cocktail?

Add 1.5 oz of vodka or gin per serving, or 2 oz of tequila for a margarita version. Blend with the rest of the ingredients. For a frozen sangria twist, use white wine instead of water.

My slushie is too icy, not smooth enough.

This usually means not enough liquid or not blending long enough. Add ¼ cup more water and blend for another 30 seconds. A high-speed blender makes a noticeable difference here.

Can I make this without a high-speed blender?

A regular blender works — just blend in two batches and stir together. You may need to add an extra ¼ cup of water to help the blender process the ice. The texture won’t be quite as smooth but it’ll still be delicious.

How do I make this for a crowd?

Multiply the recipe by 4 or 6, blend in batches, and pour into a large pitcher or drink dispenser. Stir before each pour since the ice settles. For a party, set out extra basil leaves and strawberry slices as garnish.
