The humble patty melt has been a staple of diners and restaurants across the US for decades. If you have never had one before, looking at it, it’s easy to make the mistake of thinking of it as just a cheeseburger served on bread. But it is so much more than that.

Many folks think Whataburger serves the pinnacle of patty melts with its thick crusty bread and spicy patty melt sauce. If you agree and are craving the version of the patty melt Whataburger makes, you are going to love this recipe!

What’s the Difference Between a Cheeseburger and a Patty Melt?

Let’s first get out of the way any notion that a patty melt is just a poor man’s cheeseburger. That’s not the case. Except for using the same burger patties, the two sandwiches share very little in common.

The most noticeable difference is that patty melts use bread, not buns. Although most short-order cooks make patty melts with toasted rye bread, Whataburger switches things up and substitutes thick slices of Texas-style toast.

The lightly toasted, thick-cut bread ups the crunch factor considerably and eliminates the tang of the rye bread that some people don’t enjoy.

And then there are the onions. You can’t have a patty melt without them. Even if you are someone who generally doesn’t like to put onions on burgers, you are going to love these richly caramelized onions.

If you are making a Whataburger Parry Melt, it’s well worth setting aside about an hour to make these fall-apart soft, sweet onions. However, if you don’t have the time, check out the “Tips” section below for a quicker way to make caramelized onions.

Let’s Talk About Whataburger Patty Melt Sauce

This creamy chipotle-flavored patty melt sauce is the real game-changer. It adds an incredible amount of complex flavors and takes this patty melt beyond the ordinary.

Despite the patty melt sauce’s long list of ingredients, putting it together is quick and easy, so definitely make it. You can even double the recipe and keep it covered in the fridge for up to two weeks. Try it on fries or even as a dip for veggies!

Tips for Making a Whataburger Patty Melt

  • Give rye a try. Sure, some people don’t like the taste of rye bread, but it takes the Whataburger Patty Melt in a whole new direction. Traditionally, Jewish-style corn rye was the way to go, but you can get a bit fancy by using marbled rye bread instead.
  • Steam your cheese. It’s called a patty melt, so you had better make sure that the cheese good and gooey. To melt the cheese quickly and prevent the patties from overcooking, pour a little water around the edge of the pan you are cooking in, and immediately cover with an upside-down pan. The steam from the water will take about a minute to melt the cheese.
  • Save time caramelizing your onions. Cooking the perfect onions for a patty melt can take up to 45 minutes, but who has time for that? Try this quick method of caramelizing onions from America’s Test Kitchen to cut the prep time in half.

    I have worked at whataburger in the past and I can say there is more than simply “salt” in the patties.

    Not in a “hur durr poyzin khemicels” kinda way, but just know “salt” isn’t enough.

    Also… Don’t mix the seasoning into the ground beef.. Whatever you choose to use, just don’t. It doesn’t work.

    The way it’s done at the restaurant is 100% raw patties with NO seasoning are placed on the grill. The patties are about 6″ in diameter, and around 1/8th of an inch thick when raw. The beef is 90/10.

    The seasoning is added to the top of the patty AFTER IT’S ON THE GRILL (my best guess is its a 2/1/1 mix of non-iodine salt, MSG and fine ground black pepper. That means for every two grams of salt, you add one gram of MSG and black pepper). Do not use iodine salt (usually called table salt) for this recipe.

    If you mix the salt into the ground beef before you make the burgers, you’ll end up with a chewy patty. So don’t do it. This isn’t a meatloaf that cooks for a long time, it’s a burger.

    The recipe for the sauce is “okay.” Do NOT use kraft mayonnaise – it has far too much sweetener. If you don’t use kraft, you’ll want to reduce the amount of vinegar added (because it isn’t needed). I’d say just a “splash,” maybe one or two tablespoons. Every other measurement I agree with.

    For the toast, butter is added after it’s toasted, not before. Adding the butter first will cause the milk solids to burn and give a different flavor. If you want the authentic taste, add the butter after the bread is toasted.

    No hate to the author, but that’s what happens when someone takes a “guess” at a recipe based only on taste. This recipe is a solid 9/10.

    Just adding my two cents as someone who had made this burger countless times.

    The Whataburger Patty Melt is one of my favorite things. Can’t wait to try this recipe. I usually order mine with bacon and raw onion as I am not a fan of the cooked onions on a burger, so I will make a modification or two.
