Popular Sonic Slush Flavors, Ranked Worst To Best

If you've ever been to a Sonic Drive-In, then you probably know that, aside from their large and vast food menu, they also offer a ton of drink and treat options. From milkshakes to Sonic Blasts, limeades, lemonades, soft drinks with flavor add-ins, and of course, the Sonic slush, the fast food chain has it all. But it's those delicious, one-of-a-kind Sonic slushes that really take the cake in terms of tasty beverages.

The slushes at Sonic are certainly unique, almost like an ICEE or Slurpee you can get at the movie theater or gas station, but a little thicker and with more liquid. Additionally, the slushes at Sonic come in a variety of flavors and can all be customized to your liking. That said, not all of them are made equally. The truth is, there are definitely some flavors of Sonic slushes that aren't worth your time, even though they might be more popular amongst the other diners. We've evaluated the most popular Sonic slush flavors and ranked them from worst to best. Keep reading so you can see what flavors to try and which ones you can simply leave behind.

In the same way that the plain cherry slush at Sonic is too sweet and unpleasantly reminiscent of medicine from your childhood — not to mention a little bland — so, too, is the grape slush. Honestly, though, has there really ever been a good artificial grape flavor out there? Well, Sonic's attempt is no exception. While there are certain variations of the grape slush that might make it better, a plain grape slush is just okay on its best day.

If you want to balance out the sweet and fake flavor of the grape slush, you could add in some Nerds to the Sonic drink, perhaps for some texture and visual interest. But it still won't be the best that the chain has to offer. Honestly, unless you're just a big artificial grape flavoring fan, steer clear of this one. It'll just let you down, so why would you get it?

Anyone who loves a good caffeinated beverage knows that energy drinks can really pack a punch. Not only are they loaded with caffeine — usually more than a cup of coffee, which is really saying something — but they're also sweet, flavored, and ice-cold, which typically makes them super refreshing. And at Sonic, their slush offerings have expanded to include caffeinated slushes all thanks to Red Bull. But, even if you want a jolt of energy and are already a fan of Red Bull, the Red Bull watermelon slush is actually something you'll probably want to avoid.

When it comes to the slush, the lack of carbonation and sweetness of the drink, along with the artificial watermelon flavor, drowned out any taste of the Red Bull. So, if you were looking for a sweet, frozen version of your favorite energy drink, this will probably just let you down. On the plus side, it does have caffeine from the Red Bull, so you might get a burst of energy you wouldn't get from a regular watermelon slush. That's something, but it's up to you if it's really worth spending your money on this particular slush.

Pretty much any signature drink at Sonic can be turned into a slush, and the fast food chain's lemonade is no exception. But if you order a plain lemonade slush at Sonic, you're seriously missing out. If you were to add in strawberry, or even cherry, or whatever other flavor you like, the slush would be better. But the lemonade slush by itself is just a mediocre shadow of what it could be otherwise.

But really, if you expected the lemonade slush at Sonic to taste like frozen lemonade, you will be greatly disappointed. Not only is the consistency of the Sonic slush a lot more liquid than you would normally want for frozen lemonade, but the lemonade flavor itself sn't the best. Unlike other fast food chains like Chick-fil-A, Sonic doesn't make their own lemonade from scratch, so it's not as fresh-tasting. And then when you turn it into a slush, it just becomes too sweet, overly thin, and utterly underwhelming. So, while the lemonade slush isn't the worst thing on Sonic's menu, it's definitely far from the best, especially where slushes are concerned.

As far as sweet, candy-like flavors go, blue raspberry is definitely one of the best. It's a decent combination of sweet and sour. Then again, it's not exactly a natural flavor, but it's still totally delicious to most people. So, when you turn that flavor into a slush, it's bound to be delicious, too. And to make things even better, at Sonic you can actually add Nerds candy into the slush to really make the flavor pop.

Ultimately, for many who order this drink, this slush is the perfect balance of fruity, sweet, and a little tart. And with Nerds added into the mix, the slush also gets a little more texture and becomes a drink and a little snack all in one. However, the biggest downfall of the blue raspberry Nerds slush at Sonic is that it can be a little too sweet, especially as the Nerds start to disintegrate. So, you either have to really love sweets or drink this slush fast enough to avoid it getting any sweeter.

In the world of fast food inventions, there really is no shortage of ideas that seem to come about these days. From using fried chicken as a taco shell to stuffing a pizza crust with cheese, the possibilities for junk food innovation are seemingly endless. And Sonic's Red, White, and Blue slush float is proof of just that. It might sound and even look a little off with all that food coloring, sure, but it's surprisingly tasty.

Though the drink is only a limited-time offer, it still deserves a spot on this list. The drink is basically three layers with a typical blue raspberry slush on the bottom, followed by a layer of vanilla soft serve ice cream, then a strawberry fruit topping. Obviously, the drink can be enjoyed one layer at a time, consider mixing it all together and getting a little bit of everything all in one sip. Though it might not look super appetizing once you mix everything together, it's seriously worth a shot. Thanks to that creamy soft serve offset by the tart blue raspberry and sweeter strawberry, it tastes seriously decadent and will take your taste buds for a wild ride.

Fans of Sonic Drive-In know that one of the things that the chain restaurant does best are their limeades. Specifically, both their cherry and strawberry limeades are two of their best drinks overall, so when you turn them into slushes, you can rest assured that they're going to be super tasty. And as far as the strawberry limeade slush is concerned, it's one of Sonic's best.

Imagine a tangy and refreshing limeade, served frozen in a delectable slush form, paired with the sweet and fruity taste of strawberry, and you can understand just how good this slush actually is. It's the epitome of a perfect summer drink, and it's even made with real strawberries and not just artificial strawberry flavor. This means that you get some delicious chunks of strawberry in your drink, too. Basically, this flavor is all you could want in a slush, and as good as it is, it's not even the best Sonic can do — there's some that are even better yet to come.

If you aren't a fan of limeades or just lime in general, then definitely give the Sonic real fruit strawberry slush a try. Because it's made with real strawberries and not just a strawberry syrup, it's not too sweet and doesn't have any of that fake strawberry flavor that you get from a lot of other fast food joints. Additionally, the texture of the slush — which is a little bit softer and more liquid than other types of frozen drinks — works really well with the strawberry flavor.

This slush is perfect for just about anyone, as strawberry is practically a universally beloved flavor, and the real fruit pieces in the slush make for a fun texture surprise as well. Obviously, this slush is pretty great, but because it's also pretty plain and simple it's still not quite the ultimate slush at Sonic. However, if you're a big strawberry fan, then this is probably the best slush you can order at Sonic. Sometimes, it really is best to just keep it simple.
