National Taco Day is the first Tuesday of October, coinciding with the first Taco Tuesday of the month. So why do we need a second holiday, March 21st*, National Crunchy Taco Day?

Why, to celebrate hard tacos a.k.a. crunchy tacos! They merit their own holiday because in Mexico, home of the taco, most tacos are made with soft corn tortillas (sometimes with flour tortillas, but corn is more flavorful).

So where did that crispy shell that many Americans associate with a taco come from? We’ll reveal that in a moment, but first:

To put them all in one list, the year’s four taco holidays are:

THE HISTORY OF THE CRUNCHY TACO

No one can say for certain who first fried a soft tortilla and filled it, but they appeared in Mexico sometime after the soft version.

 
While these two exist in traditional Mexican cuisine, the mass-produced, pre-formed crunchy shell was popularized in the 1950s by Glen Bell (the founder of Taco Bell) to make them easier to serve quickly.

The earliest American recipe for hard tacos was published in a California-Mexican cookbook in 1914. A corn tortilla was stuffed with ground beef, sealed, pan-fried, then [wait for it!] smothered it in chili gravy [source].

In the U.S. they are called hard shell tacos or crunchy tacos.

In terms of who popularized the hard shell in the U.S.: Point your finger at Gene Bell of Taco Bell.

When he launched what would become a major American food franchise on March 21, 1962, in San Bernardino, California†, he put crunchy tacos—fried tortilla shells, not soft tortillas—on the menu. Crunchy tacos were easier to prepare than soft ones.

(Note the date? It became National Crunchy Taco Day).

Bell was the first taco seller to fry his taco shells in advance (traditionally they were fried on demand).

With all due respect, not all hard-shell tacos taste like Taco Bell, Del Taco, or other chains, much less Old El Paso shells from the supermarket. They’re pretty tasteless.

A quality Tex-Mex restaurant—whether fancy or a taco truck—will fry them fresh daily.
 
 
CRUNCHY TACOS VS. SOFT TACOS: THE DIFFERENCE

Crunchy tacos, also called hard-shell tacos, are corn tortillas fried into a U shape. Rigid, they are stuffed with meat, seafood, or beans, plus lettuce, tomatoes, and cheese (and many add-ons, from guacamole to sour cream).

Some sources call them Anglo-Tacos and/or Cali-Mex cuisine.

While prefabricated taco shells have a bad reputation, when prepared freshly with care, the Tex-Mex crunchy taco is delicious.

If you’re pining for crunchy tacos, head to a good Mexican restaurant that fries them from scratch.
