Does Sonic Have Sugar-Free Slushies?

In the mood for a Sonic Slushy? Wondering if Sonic has a sugar-free slushy option? How about any sugar-free menu items at Sonic?

I’ve done some digging around and have what you’re looking for. 

Well, when it comes to ordering at Sonic, you be mighty lucky to find anything worthy of being branded as sugar-free.

It’s no secret that Sonic’s meals are generally considered to be just as unhealthy as any other fast food joint in the country, but does that mean that there is simply no option for a sugar-free meal?

If we can’t settle on a meal, can we at least settle on one of their drinks?

My Long History With Sonic Slushies

Well, you have come to the right spot for your answer because I used to work at Sonic. In fact, it was my very first job as a teenager.

I was one of their carhops (no I did not skate…I would have dropped a lot of people’s drinks, haha!) and I also ran the “fountain” as we used to call it.

So I was the one responsible for making those slushies and any other drink or ice cream ordered. I actually have very fond memories of working there (Shout out to all my Sonic co-workers!).

Of course, that was way back when I was happy to partake in all of the sugary sweet drinks.

Since it has been a very hot minute since I have worked there, I took the time to re-look at their menu and see what they’ve got to offer to try today.

Not surprisingly, a lot of it is the same (don’t fix what isn’t broke, right?). I will delve deeper into this later so, read on!

Does Sonic Have Sugar-Free Slushies?

I could answer this question in one word. That word is “no”. Sorry to say this, but it appears that Sonic does not have a sugar-free option for any of their slushies across their menu.

That’s a shame, considering they are super tasty.

What’s worse is that they brand some of their slushies as “diet”, which usually means there is no sugar involved… Although, this is not the case for Sonic.

The main reason for this is that the base of the slushy itself is where most of the sugar is concentrated.

That means that even without any added toppings or flavorings, the base alone will be too much sugar for anyone looking to lead that sugar-free lifestyle.

A plain slushy on its own holds an awful amount of sugar – 48g if you want to be exact. It’s also 180 calories. That’s just the base slush.

That means that whatever diet slush you want to get for yourself, you’ll always be consuming at least 48g of sugar.

They really should be avoided at all costs if you’re trying to avoid sugar – and they’re certainly not good for keto or diabetes.

Are There Any Sugar-Free Items At Sonic?

Leading a no-sugar lifestyle can be difficult when it comes to buying from places like Sonic, there’s no question about that.

Since their slushies have already been completely taken off the table because they go against everything we stand for in our sugar-free lifestyle, are there any other menu options that work for us?

Again, I could keep this pretty simple and just start with a very hearty “no”.

Unless you are just eating tater-tots or french fries or drinking a plain diet drink, there doesn’t appear to be anything specific to Sonic’s menu that is truly sugar-free.

Even their chicken strips contain 8g of sugar. Now if you are still in the mood for some fast-food chicken, Raising Cane’s Chicken contains zero grams of sugar per serving and it is pretty darn good.

Now, I did find that the Jr. Bacon, Egg, and Cheese Burrito says there are zero grams of sugar per serving. However, the non-jr version says there is 1g of sugar.

I personally know from reading lots of labels, that most things will still contain added sugar even if it says 0g per serving.

The amount sometimes is just so small that it registers as less than 1g so they are able to say 0g. Which is unfair honestly.

To me, it is still a lie. And I would even bet the Raising Cane’s chicken probably still has some added , too. An even bigger idea, why even put the sugar in there anyway if it is such a trivial amount?!!

At least we can still enjoy some tasty treats at any local Starbucks, you can even order it sugar-free from the Starbucks App.


Hopefully, my research into the topic of sugar-free items on Sonic’s menu has enlightened you. Unfortunately, none of their slushes are truly sugar-free, so I would try to avoid them if you can!

We also learned that just because it says 0g does not mean there is actually no added sugar in it.

Leave those for the people that don’t mind a little extra indulgence of sugar in their lives!

If we want to get a drink from Sonic, then I’d suggest one of the diet Sodas. Alternatively, you could just stick with water! Sorry, I had to mention it!


Welcome, and thank you for your joining me! I am a recovering sugar addict. I could not go a day without needing something sugary and worse than that, I was constantly thinking about eating sweets. For that reason, I chose to go sugar-free. I'm proud to say that I am now going into my 6th year of being mostly sugar-free. I say mostly because, let's be real, processed sugar is literally in everything. This is why I wanted to write this blog. To help others just as I helped myself.
