Whataburger Patty Melt Copycat Recipe

The Whataburger Patty Melt stands as one of the most beloved items on their menu, and for good reason. This isn’t just another burger served on bread. It’s a masterpiece of thick, buttery Texas toast embracing perfectly seasoned beef patties, gooey Monterey Jack cheese, sweet caramelized onions, and that signature creamy pepper sauce that makes everything extraordinary.

This copycat recipe is even better because you never have to worry about it being a limited-time menu item again.

The magic lies in the details: the thick-cut Texas toast that delivers incredible crunch, the fall-apart tender caramelized onions, and that complex chipotle-flavored sauce that transforms an ordinary sandwich into something unforgettable.

Why This Recipe Works

This two-component approach (sauce and sandwich) creates layers of flavor that develop beautifully. The creamy pepper sauce needs time to meld its complex flavors, while the slow-caramelized onions develop natural sweetness that balances the rich, spicy sauce. The thick Texas toast provides the perfect sturdy foundation that won’t get soggy.

Ingredients

Creamy Pepper Sauce

  • Mayonnaise – Forms the creamy base and carries all the flavors
  • Dry mustard powder – Adds sharp, tangy depth without liquid
  • White vinegar – Provides acidic brightness to balance richness
  • Fresh lemon juice – Adds citrus complexity and freshness
  • Chipotle peppers in adobo sauce – Creates smoky heat and complex flavor
  • Freshly cracked black pepper – Contributes aromatic spice and texture
  • Ground white pepper – Adds heat without visible specks
  • Salt – Enhances and balances all other flavors
  • Onion powder – Provides savory depth and umami
  • Garlic powder – Adds aromatic complexity without fresh garlic bite
  • Dried parsley – Contributes herbal freshness and color
  • Accent flavor enhancer (MSG) – Optional umami booster for restaurant taste

    What do you use if you can’t get Texas toast when your local Kroger super market doesn’t have it all the time?

  2. Zane

    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.
