Putting Mustard on Burgers Is the Texas Way

The weather’s heating up, grills are coming out, and burgers are about to be on heavy rotation.

And while everyone has their go-to toppings, there’s one debate that hits a little different in Texas: what actually belongs on a burger?

Because if you ask Texans, the answer isn’t ketchup. It’s mustard!

The Texas Way to Build a Burger Starts With Mustard

If you’ve ever ordered a classic Whataburger and wondered why mustard comes standard, there’s a reason, and it’s not random.

That mustard-first build goes all the way back to 1950, when the first Whataburger opened in Corpus Christi. From the very beginning, mustard wasn’t just a topping, it was the foundation. It’s also why, to this day, when you order a classic Whataburger, mustard still comes standard.

You can customize it, sure, but that original build is straight out of Texas tradition.

Why Whataburger Still Puts Mustard First in Texas

That default order isn’t just about taste, it’s about legacy.

Whataburger helped cement mustard as the go-to burger base across Texas, and decades later, it’s still the starting point for millions of orders. It’s one of those small details that quietly defines what a “Texas burger” really is.

Long before customization was the norm, burger joints across Texas were already doing things their own way. Mustard, pickles, onions, lettuce, tomato, that was the build. Ketchup and mayo? Those came later.

So if mustard has always been your go-to, you’ve actually been doing it the Texas way all along.

The Real Reason Mustard Won in Texas

There’s also a practical reason behind it.

Back in the early days of burger stands, mustard held up better in the Texas heat than other condiments. It didn’t spoil as quickly, and it kept that bold flavor even in less-than-ideal conditions. In other words, mustard didn’t just taste better, it just made more sense.

But if you leave Texas, suddenly ketchup takes over. In some places, a mustard-based burger is literally called a “Texas burger,” which kind of says everything you need to know.

You can customize your burger however you want. But if you ask around, most Texans will tell you the same thing, the base matters. And that base starts with mustard.

Everything else is just extra.
