Introduction

National Crunchy Taco Day celebrates a food most Americans associate with fast-food drive-throughs, but the crunchy taco's real story starts decades before any chain got involved. A 1914 cookbook contains the first known English-language recipe for fried tacos. A 1937 cafe in San Bernardino served them to Mexican immigrant workers. And a 1950 patent for a taco shell frying machine, filed by a Mexican immigrant named Juvencio Maldonado, mechanized production years before anyone had heard of Taco Bell.

The holiday falls on the anniversary of the first Taco Bell opening in 1962, but the food it celebrates has a longer and more complicated lineage than the franchise that popularized it.

National Crunchy Taco Day History

The crunchy taco's roots are in Mexico, where cooks have fried corn tortillas into tacos dorados for generations. The technique is straightforward: fill a tortilla, fold it, and fry it until the shell turns golden and rigid. The dish crossed into the United States with Mexican immigrants, and by the early 1900s, fried tacos were available in Mexican-American communities across the Southwest.

The first known American recipe appeared in 1914, when Bertha Haffner Ginger published the California Mexican-Spanish Cookbook. It described fried, filled tortillas in terms that would be recognizable to any modern taco eater. By 1937, Mitla Cafe in San Bernardino was serving crunchy tacos to a steady clientele, run by the Montano family.

The patent nobody remembers

In New York, a Mexican immigrant named Juvencio Maldonado solved a practical problem. Frying individual tortillas by hand was slow and dangerous. Maldonado, an electrician by training, built a metal form that held tortillas in a U-shape while submerged in oil, allowing cooks to fry multiple shells at once.

He received U.S. Patent No. 2,506,305 in 1950. His invention worked, but it never scaled beyond his own restaurant.

Glen Bell and Taco Bell

Glen Bell, a hot dog stand operator in San Bernardino, ate regularly at Mitla Cafe and studied how the Montano family prepared their tacos. He adapted the method for speed and opened a series of restaurants, Taco Tia and El Taco, before launching the first Taco Bell on March 21, 1962, in Downey, California. Bell sold crunchy tacos for 19 cents each.

The format was designed for volume: pre-fried shells, a standardized filling line, and minimal wait times. Taco Bell began franchising in 1970 and now operates over 8,000 locations worldwide.

National Crunchy Taco Day Timeline

1914

First American crunchy taco recipe published

Bertha Haffner Ginger published the California Mexican-Spanish Cookbook, which included the earliest known American recipe for fried, filled corn tortillas. The recipe described what would later be called a crunchy taco.

1937

Mitla Cafe begins serving crunchy tacos

Mitla Cafe in San Bernardino, California, run by the Montano family, began serving fried corn tortilla tacos. The restaurant became a gathering place for the local Mexican-American community and a model for future entrepreneurs.

1950

Juvencio Maldonado patents taco shell machine

Juvencio Maldonado, a Mexican immigrant and electrician in New York, received U.S. Patent No. 2,506,305 for a device that held tortillas in a U-shape while frying, allowing cooks to produce multiple shells simultaneously without burning their hands.

1962

First Taco Bell opens on March 21

Glen Bell opened the first Taco Bell restaurant in Downey, California, featuring crunchy tacos as the centerpiece of the menu. Bell had previously sold tacos at his Taco Tia and El Taco restaurants after learning the technique from Mitla Cafe.

1970

Taco Bell begins franchising nationally

Taco Bell expanded through franchising, bringing the crunchy taco from a regional Southern California item to a national fast-food staple. The company grew from a single location to hundreds of stores within a decade.

How to Celebrate National Crunchy Taco Day

1

Make tacos dorados from scratch

Heat corn tortillas, fill them with seasoned meat, fold, and fry in oil until golden. Serious Eats' tacos dorados recipe walks through the traditional technique step by step and produces a flavor that store-bought shells cannot replicate.
2

Try a crunchy taco from a local taqueria

Skip the drive-through and find a family-owned taqueria that makes crunchy tacos to order. The difference between a mass-produced shell and a freshly fried tortilla is significant. Search for 'tacos dorados' in your area and look for spots that fry their shells fresh.
3

Read about Juvencio Maldonado's patent

Juvencio Maldonado's 1950 invention is documented in U.S. Patent No. 2,506,305. Reading it alongside the history of Taco Bell shows how Glen Bell adapted crunchy tacos from a San Bernardino cafe and built them into a global fast-food chain, decades after Maldonado patented the taco shell frying machine.
4

Host a crunchy taco bar

Set out fried shells, seasoned ground beef, shredded chicken, lettuce, diced tomatoes, cheese, salsa, and sour cream. Let people build their own. The crunchy taco's design makes it one of the easiest dishes to serve as a group meal.
5

Compare store-bought shells to homemade

Buy a box of pre-made taco shells and fry a batch of corn tortillas at home. Taste them side by side. The commercial taco shell was engineered for shelf stability, not flavor, and the difference is instructive.

Why We Love National Crunchy Taco Day

A

It represents an entire category of Mexican-American cuisine

The crunchy taco is not traditional Mexican food and not entirely American. It exists in the space between the two, a product of Mexican ingredients and techniques adapted for American speed and scale. National Crunchy Taco Day marks one of the most successful examples of cross-cultural culinary adaptation in American food history.
B

It built a global fast-food chain

Taco Bell, built on the crunchy taco as its foundational product, now operates thousands of locations worldwide and generates billions in annual revenue. The chain's entire business model traces back to a single fried tortilla sold from a walk-up window in Downey, California.
C

It obscures the contributions of Mexican inventors

The crunchy taco's popularity is often credited to Glen Bell, but the technique came from Mitla Cafe, the first patent belonged to Juvencio Maldonado, and the underlying dish, tacos dorados, has been part of Mexican cuisine for far longer than any American brand. National Crunchy Taco Day is an opportunity to credit the full lineage, not just the franchise.
