Why It Works

  • Whether they're homemade or store-bought buns, the tight uniform interior crumb of the bread and its sturdy flakiness ensures they are hardy enough to hold the hot dog’s abundant toppings.
  • Baking the completo buns side by side in pairs creates one fused, flat, rugged side on each bun that accommodates the generous toppings.

I can safely say that every Chilean has a memory with completos, our beloved loaded hot dogs that are found throughout the country. And as a child, I was lucky because my family owned the only restaurant in our little Chilean town of Arauco that specialized in sandwiches and completos. While my classmates would enjoy these loaded hot dogs as an occasional celebratory treat, my family ate them every Sunday night. I remember my mom arriving home with a greasy cardboard box full of still warm, freshly made completos; I recall the joy of my teenage brothers; the anxious passing of the many condiments around the table; my dad pouring a cold beer. It was my definition of a happy childhood.

Completos, unlike many other traditional Chilean dishes such as sopaipillas and pantrucas, have a traceable origin story. In the 1920s, Chilean restaurateur Eduardo Bahamondes tried American hot dogs on a trip to New York and dreamed up a business opportunity with his first bite. His restaurant Donde Bahamondes, located in Santiago’s main square, is famous for its hot dogs and remains a great place to eat completos, with happy eaters frequenting the shop at all hours.

Besides being sold in street carts and restaurants, completos are a mandatory part of Chilean celebrations and special family occasions. The popular way to enjoy them is during our local version of teatime, called once. Once is similar to English-style afternoon tea time, but it is served later and often it replaces dinner. Once usually includes bread, toppings and pastries or cake, and for special celebrations once also includes completos: each member of the family will help by mashing avocados, dicing tomatoes, or making the mayonnaise, until a colorful assortment of toppings and condiments fills the table. Sauerkraut, salsa Americana (finely chopped vinegar pickled veggies, similar to giardiniera), mustard, hot sauce and ketchup are served as well. Lastly, completo buns—bought in a local Chilean bakery—are carefully toasted in a Chilean stovetop tostador and vienesa sausages are boiled, steamed or pan fried. Hot tea (or sometimes beer) is served and everyone is left to top their own hot dog as they see fit. The two most popular completos topping combinations are known as completos Italianos and completos completos (yes I recognize that name is a bit confusing). I’ve written these combinations as options in the recipe steps below, but feel free to include any combination of these listed toppings. 

This experience is my epitome of family life in Chile, and a moment I missed deeply when I lived abroad in the US. My time without completos is what inspired me to create my own recipe, one that even includes making the buns from scratch. Here are my tips for a great Chilean hot dog experience at home.

Tips for an Authentic Completos Experience

For the best completos, bake the buns from scratch. The classic completo buns are nothing like standard US hot dog buns. Our Chilean hot dog buns are larger, sturdier, and not as sweet as their American counterparts. The bulkier long bun is designed to accommodate the large amount of toppings that are a staple on every completos. The dense crumb structure in these homemade buns is perfect for absorbing tomato juices and the heaps of avocado and mayo that completos usually carry. And the crust, when reheated or toasted, will form a thin, crunchy layer that makes every bite even more enjoyable. I firmly believe that for a true Chilean completos experience, the completo buns should be made from scratch, so I’ve included my recipe here. But if that is not possible, substitute with bakery-made 8-inch long hoagie rolls that have a similar, sturdy structure.

Don’t skimp on the mayo. Another thing that makes Chilean completos unique is the amount of mayo on them: what for us Chileans is the perfect amount of mayo on a hot dog might be an obscene amount of mayo for many. As I stated in the Santiago episode of “Somebody feed Phil” (season six on Netflix), we consider the mayo to be a mandatory core ingredient, not just an optional condiment. An average completo should have about a quarter to a half cup of mayo per bun, at least! But I’ll admit, this is a bit excessive for my own taste. When I order them out, I always ask for “poco mayo maestro," to make the cook reduce the amount.

I recommend using Kenji’s two minutes mayo, it's an approachable recipe with a silky texture and rich flavor that is perfect for completos. If you're not up for making your own mayo, I find that Kraft mayo comes close to the texture and flavor of the mayo you’d find in Chilean fuente de soda shops, where completos are often served. The brand is a local favorite for that reason.

Load up on the hot dogs. In Chile we use “vienesas” or wieners, a mild and sometimes slightly smoky hot dog sausage that is usually boiled, steamed or pan fried. Standard US brand hot dogs, such as Hebrew National or Nathan’s will work well, and if you have a local favorite, by all means use that. I recommend using 1 1/2 hot dogs to fill out each completo. A standard 6-inch long hot dog is too short on its own to fill out the longer bun, and a great completos should contain meat in every bite.

Assemble with purpose. The placement of the diced tomatoes—over or under other toppings—has lately become a controversial topic in Chile. According to Javier Rodríguez expert completo journalist and owner of the completo IG account @soycompletero, the division started because Dominó, a popular completo restaurant chain, serves their hot dogs with tomatoes on top. Because of their huge following, many people grew up believing completos should be assembled like that. But other Chileans, myself included, prefer adding tomatoes under the other toppings. This allows the tomato juice to drip into and moisten the bun. But, if you can't stand the idea of a soggy bun, do as many Chileans do and “wet proof” the bread with a layer of avocado (or a bit of mayo) and then pile on the other ingredients.

Once your preferred toppings of tomatoes, sauerkraut, salsa Americana, and and avocado are loaded on, spoon a generous smear of mayo, slowly, ceremoniously down the length of the hot dog to seal and lightly secure everything in place. The mayo also creates a clean canvas for a final squeeze of mustard, hot sauce, or ketchup. The end result is a colorful and fully loaded Chilean completos that is a work of art.

Serves 6

Ingredients

For the Completo Buns (If making):

  • 500g all-purpose flour (17.6 ounces; about 4 cups)

  • 10.5g (1 tablespoon) instant or fast-acting yeast, such as SAF (not rapid-rise)

  • 9g (1 tablespoon) kosher salt 

  • 125ml whole milk, lukewarm (1/2 cup plus 1 1/2 teaspoons)

  • 125ml water, lukewarm (1/2 cup plus 1 1/2 teaspoons) 

  • 1 large egg, at room temperature

  • 18.75g (1 ½ tablespoons) granulated sugar

  • 3 tablespoons butter (45g) unsalted butter, softened and cut into 3 pieces

  • Vegetable oil for brushing buns

  • 1 large egg yolk beaten with 1 ounces milk, for the egg wash

For Assembling and Serving the Completos:

  • 9 natural casing all-beef hot dogs, grilled or steamed as instructed below in recipe

  • 6 completo buns from recipe above, or 6 store-bought 7 to 8-inch long hoagie rolls

  • 1 1/2 pounds tomatoes (plum, beefsteak or any red heirloom variety), finely diced and lightly salted

  • 4 medium ripe avocados, mashed until chunky with a fork in a bowl and lightly salted to taste

  • One 16 fluid-ounce jar naturally fermented sauerkraut, drained

  • One 16 fluid-ounce jar mild italian Giardinera, drained and finely chopped

  • 1 cup two-minute mayonnaise recipe or store-bought mayonnaise

  • Chilean mustard or yellow mustard 

  • Chilean ají crema or any mild hot sauce such as Sriracha

  • Ketchup

Directions

  1. For the Completo Buns: (If using store bought hoagie buns, skip to step 9) In the bowl of a stand mixer, whisk together flour, yeast, and salt. In a 4-cup liquid measuring cup or large bowl, whisk water, milk, egg, and sugar until sugar is dissolved.

  2. Using a dough hook on low speed, slowly drizzle water mixture into flour mixture and mix, scraping down bowl as needed, until cohesive dough forms and no dry flour remains, about 2 minutes. With mixer running, add butter, 1 tablespoon at a time, waiting until the butter is fully incorporated into the dough before adding the next tablespoon, until all butter is fully incorporated, about 3 minutes. Increase mixer speed to medium and knead for 8 minutes, until dough is smooth and elastic and clears sides of bowl but still sticks to the bottom.

  3. Transfer dough to a lightly floured work surface and knead by hand to form a smooth round ball, about 1 minute. In a lightly greased large bowl, place the dough seam side down, cover the bowl tightly with plastic wrap or a large plate, and let rise at room temperature, 68 to 74℉ (20 to 23 ℃), until the dough is doubled in size, 1 to 1 1/2 hours.

  4. Line 2 rimmed baking sheets with parchment paper; set aside. Press down on dough to deflate and transfer the dough to a clean work surface. Using a bench scraper or sharp knife, divide dough in 6 equal pieces (about 145g each). Shape each piece into a smooth ball and set aside on the counter. Cover loosely with greased plastic wrap or a kitchen towel.

  5. Working with one dough ball at a time, use your hands to flatten ball into a 5- x 4-inch rectangle. Fold the upper third of the dough toward the center. Fold the lower third of the dough to the center, mimicking an envelope fold, and lightly pinch the edges of both folded pieces together and press gently to seal the center seam where the folds meet. Then press the new seam into the bun, so it almost disappears.

  6. Roll the bun over, seamside down, and using the palms of your hands, gently roll the bun into a 7 ½ inch log. Repeat with the remaining dough balls, recovering the unused pieces with the greased wrap or kitchen towel. Once all are shaped, using your hands, roll each log again so they each are now 8 ½ inches long and even thickness from end to end.

  7. Adjust oven rack to middle position and preheat oven to 375℉(190℃). Transfer 4 buns to one prepared baking sheet seam-side down, and 2 to the other sheet; Set the puns side by side in pairs with 1 inch of space between each bun in the pair. Using a pastry brush, brush buns lightly with vegetable oil and cover loosely with a kitchen towel or greased plastic wrap and proof at room temperature until puffed, and are 9-inches in length, and dough springs back minimally when poked gently with your knuckle, 30 to 45 minutes.

  8. Using a pastry brush, brush proofed buns with the prepared egg wash. Bake buns until golden brown for about 12 to 15 minutes. Transfer to a wire rack and let cool.

  9. For steaming the hot dogs: Bring 1 1/2 cup water to boil in large saucepan over high heat. Place steamer basket over boiling water. Add hot dogs to basket, cover saucepan, and reduce heat to medium. Cook until hot dogs are heated through, 5 to 7 minutes.

  10. For assembly with the toppings: Slice each bun open lengthwise, leaving hinge attached. Transfer buns to a rimmed baking sheet and warm in the oven until just warmed through.

  11. Fill each bun with 1 1/2 steamed or grilled hot dogs (the idea is to fill the whole length of the bun). Serve with the suggested toppings, letting each person assemble their own completos. (Serving suggestions below.)
