What it means
A Sonoran hot dog is a hot dog that has been wrapped in bacon, grilled until the bacon crisps and the fat soaks the frank, set in a soft, slightly sweet bolillo roll with a split top, and then buried: pinto beans first, then chopped tomato, grilled onion, raw onion, a ribbon of mayonnaise, a stripe of mustard and a spoon of jalapeño salsa, sometimes cheese, with a roasted yellow güerito chile on the side. It is eaten standing, at a cart with a fluorescent light and a griddle, and it costs a few dollars.
Scottsdale is not its natural habitat. The site’s what-to-eat guide is blunt about it: the best ones are sold from carts and small stands in Tucson and in south and west Phoenix, and the accessible Old Town version at Diego Pops is a reasonable introduction rather than the destination. This page explains the thing and points you toward it.
Where you’ll meet it
On the Diego Pops menu next to the Brussels sprout nachos, on the “Sonoran” section of modern Mexican menus around the Valley, at carts along the big south and west Phoenix avenues after dark, and at the top of every reason to make the day trip to Tucson, a UNESCO City of Gastronomy that treats the Sonoran dog as civic property.
Where the word came from
The hot dog went to Mexico and came back changed. In Hermosillo, the capital of Sonora, street vendors began dressing American-style franks with the toppings of the Sonoran kitchen, beans, onion, chile, mayonnaise, and wrapping them in bacon for the grill. When this started is argued. Wikipedia’s summary of the record places the style’s rise in Hermosillo in the late 1980s, while other accounts trace bacon-wrapped dogs to ballpark concession stands there in the 1940s. Nobody has produced a document, and the honest answer is that Hermosillo invented it sometime in the second half of the twentieth century and Tucson noticed.
Tucson is where it became an institution. Sonoran vendors, dogueros, set up carts on the south side, and by 2009 more than 200 of them were selling Sonoran dogs in Tucson, with even more in Phoenix. The best known is El Güero Canelo, which Daniel Contreras, a Sonoran native, opened in 1993 at age 33 as a small cart serving bacon-wrapped hot dogs with Mexican toppings. It grew into several Tucson stands and a bakery for the buns, and in 2018 the James Beard Foundation named it one of five America’s Classics, the award for beloved regional restaurants. Contreras’s own explanation of the win was the bread: “The bun makes a big difference.”
Phoenix got the dog in the same migration, mostly through carts and small storefronts in the Sonoran neighborhoods of the south and west sides, and the Valley’s Sonoran restaurants, El Caprichoso among them, made it a menu item. Scottsdale got it last and lightest, as a line on the menus of the taco-and-tequila rooms.
What it is not
It is not a chili dog, and it is not a “Mexican hot dog” in the Los Angeles sense, where bacon-wrapped dogs come with grilled peppers and no beans. Ketchup is not involved. And a hot dog with jalapeños on a hamburger bun is a hot dog with jalapeños; the bolillo is not optional.
The fine print
The anatomy, for the record. The bun is a bolillo, the Mexican roll, baked soft and split from the top so it cradles the frank and holds a load of beans without tearing; El Güero Canelo’s are steamed, and its bakery exists because ordinary rolls fail. The frank is an ordinary beef or pork hot dog, wrapped in a strip of bacon and griddled or grilled until the bacon is crisp on the outside and soft where it meets the meat. The beans are whole pintos, warm. Onion comes two ways, grilled and raw. Tomato is chopped fresh. Mayonnaise goes on in a zigzag from a squeeze bottle, mustard in a thinner one, and the jalapeño salsa is a thin green sauce rather than a chunky pico. The güerito on the side is a mild yellow chile roasted on the same griddle, which you eat in bites between the dog. Cotija or shredded cheese is a common addition and not a heresy.
Where it belongs in the Arizona canon: it is the street version of the same Sonoran kitchen that produced carne asada and the chimichanga, and, like them, it crossed a border that moved before the food did. Tucson’s claim to it is a claim of adoption, which the city makes proudly, and Hermosillo does not seem to mind.
The practical advice is the guide’s: eat Diego Pops’s version in Old Town when you want one with a margarita, and when you are ready for the real thing, drive toward the carts. The late-night guide notes how little of this genre Scottsdale keeps after dark; the Phoenix avenues keep it until the small hours.
