But what makes the signature sandwich so popular? From first glance, Whataburger's patty melt looks like a grilled cheese and a burger had a baby, which is certainly enticing. Take a closer look, though, and you'll fall in love with the details of the melt beyond the juicy beef patty - the true-to-Texas-pride Texas toast, the creamy pepper sauce, the Monterey jack cheese, and the grilled onions.
The way to a spicy Whataburger breakfast is simple: Order any biscuit sandwich or biscuits and gravy and swap out the buttermilk biscuit for the jalapeño cheddar biscuit. It's the same calorie count as the buttermilk biscuit (330 calories if you're keeping score), and the best part? No extra charge. This swap is available at all Whataburger locations from 11 p.m. to 11 a.m.
It's a chef's quiet confession: Even the most celebrated cooks sometimes crave a drive-thru treat. For celebrity chef Aarón Sánchez, the indulgence of choice is Whataburger - and not because of nostalgia alone. The Texas-born chain builds its burgers with mustard as the only condiment cozied up beside diced onions, pickles, lettuce, and tomato, and for Sánchez to claim it as his favorite fast food restaurant burger is quite the endorsement.
