The 10 Best Spicy Fast-Food Sauces of All Time—Ranked!

Fast-food sauces are often the link between a dull meal and a meal that sings.

Fast-food sauces are often the link between a dull meal and a meal that sings. A chicken nugget, for example, is unthinkable without a dunk in a smoky barbecue sauce or tangy honey mustard. And who eats a taco without some kind of fiery drizzle? All fast-food lovers have their favorite and the return of a beloved sauce, like McDonald's Szechuan sauce, can cause quite a stir.

Recently, many restaurants have jumped on the spicy bandwagon to provide even more of a flavor punch. Ranker, a site that bases lists off of votes from its readers, has a page dedicated to these spice-kissed sauces. Here are the top 10 spicy fast-food sauces of all time, ranked from least to most popular.

This sauce is a tangy, very slightly spicy combination of jalapeno peppers and green bell peppers and is the perfect accompaniment to McDonald's breakfast burritos. While it may taste great, a Vice article disputes the spice level of this salsa-like sauce, arguing, "This is not spicy enough to warrant a 'Hot' or a 'Picante.' Still, I will get this every time I go to McDonald's."

Jack in the Box knows that if they serve Buffalo sauce, it better be the good stuff. Franks has long been synonymous with the perfect wings sauce and is one of the most popular hot sauces in general, so it's no surprise that Jack in the Box serves this spicy classic. But why mess with a good thing?

Although the sauce is branded as "Franks Red Hot," one fan believes that the fast-food version isn't the same as store-bought Franks Buffalo sauce, noting that the addition of cornstarch gives it a thicker consistency that's "closer to a BBQ sauce."

The KFC hot sauce is described as having a "smooth, viscous mouthfeel, with good vinegar pucker," and on this Reddit thread fans of the sauce debate whether it is more like Texas Pete or Crystal hot sauce.

Fans really, really like Del Taco sauces, to the point where they are sold by the case online, as spicy stocking stuffers, and even keychains. Del Scorcho which is flavored with ancho chili pepper may sound hot, but it is actually Del Taco's medium salsa. Del Inferno is the hottest.

McD's describes their Buffalo sauce as "a peppery sauce with vinegar and butter flavor… with a building heat" which makes it sound just like a classic Buffalo sauce. Since chicken and Buffalo sauce are a match made in heaven, this sauce makes perfect sense next to the nuggets.

Taco Bell Mild Sauce

1 tsp: 0 calories, 0 g fat, 25 mg sodium, 0 g carbs, 0 g protein

As you've probably ascertained, the mild Taco Bell sauce is the mildest of the traditional sauces. Most reviews don't call this a true hot sauce, but more of a mild taco sauce. Yet, it appears third on this list, and others state that it has a teeny, tiny kick for them.
