Is hard seltzer keto?

The most common hard seltzer drinks you will see in the grocery store are White Claw and Truly. Both of these options do contain sugar, but it’s a very, very slow amount so they only have 2 grams of carbs per can. Lots of people drink hard seltzers on the keto diet. As long as you watch you daily carb count, hard seltzer drinks like White Claw and Truly are keto approved. Look for the berry flavored Truly or a raspberry flavored White Claw but any flavor of seltzer will work in this keto white claw slushie recipe. Some others include, Mango White Claw, Black Cherry and Lime.

Sugar-free ginger ale

Traditionally, ginger ale is loaded with sugar so make sure you don’t purchase regular ginger ale because it has lots of carbs in it. There are sugar-free options for ginger ale available at most grocery stores.
  • Zevia Ginger Ale – Zevia drinks are soda replacements that are sweetened with the plant-based sweetener, stevia. They contain no artificial sweeteners or sugar. They are also gluten-free, vegan and free of caramel color.
  • Canada Dry Diet Ginger Ale – This diet ginger ale is sweetened with Acesulfame Potassium and has caramel coloring.
  • Sparkling Ice Ginger Lime – This sugar-free ginger beverage is sweetened with sucralose and has fruit juice for coloring. It has zero carbs per serving.

Keto mocktail recipe

If you don’t drink alcohol or want to make a version for your kids, you can make an alcohol-free version of this keto hard seltzer slushy. An alcohol-free cocktail is called a mocktail! Instead of adding the hard seltzer, you can add either add more sugar-free ginger ale or flavored seltzer water. You may want to add a keto approved sweetener especially if you are making a strawberry slushie for the kids.

Favorite keto sweetener

This keto hard seltzer strawberry slushie doesn’t need additional sweetener. It is mildly sweet on its own from the frozen strawberries. If you want additional sweetness, you can add your favorite keto sweetener before blending. You options of keto approved sweeteners are monk fruit, erythritol, stevia or allulose. My favorite sweetener is by Lakanto. They have a powdered monk fruit based sweetener and a classic granular version. You can save 15% off your order with the Lakanto link above or use code KETOFOCUS at checkout.

Best blender for blended cocktails

If you want the smoothest keto blended cocktail, you have to invest in a really good blender. There are several options out there that are high powered blenders perfect for pulverizing ice into a slushy. Here are some of my favorites: As an Amazon Associate, I earn from qualifying purchases

Frequently Asked Questions

Can I use fresh strawberries instead of frozen for the slushy?

While frozen strawberries give the slushy its icy texture, you can use fresh strawberries if you don't have frozen ones. Just add a bit more ice to achieve the desired slushy consistency!

What if I don't have powdered monkfruit?

If you don't have powdered monkfruit, you can substitute it with another keto-friendly sweetener, like erythritol or stevia, adjusting the amount to your taste.

How should I store any leftover slushy?

It's best to enjoy the slushy fresh, but if you have leftovers, store them in an airtight container in the freezer. Just note that it may lose some of its slushy texture and become icy.

Can I make this slushy non-alcoholic?

Absolutely! Just replace the hard seltzer with more sugar-free ginger ale or a flavored sparkling water to keep the slushy refreshing and fun without the alcohol.

Is this slushy suitable for a keto diet?

Yes! This Keto Hard Seltzer Strawberry Slushy is sugar-free and low in carbohydrates, making it a perfect option for those following a keto diet.
