There is a world of difference between a store-bought, pre-formed taco shell and one that has been freshly fried in your own kitchen. While the yellow boxes in the grocery aisle offer convenience, they often lack the delicate crunch and rich, toasted corn flavor that defines a truly great taco. Learning how to fry taco shells is a culinary rite of passage that elevates a simple weeknight dinner into a gourmet experience.
The process is surprisingly straightforward, but it requires a bit of technique to ensure the shells are crispy rather than greasy, and structurally sound rather than brittle. By mastering the oil temperature and the “fold-and-hold” method, you can create shells that provide the perfect vessel for everything from seasoned ground beef to carnitas.
Choosing Your Ingredients and Tools
Before you turn on the stove, you need to gather the right materials. The quality of your tortilla and the type of oil you use will directly impact the final result.
The Tortilla
Corn tortillas are the traditional choice for hard taco shells. White corn tortillas tend to be a bit more delicate and mild, while yellow corn tortillas offer a robust, earthy flavor and a slightly sturdier texture. When selecting tortillas, look for ones that are fresh and pliable. If they feel dry or cracked in the package, they are more likely to split when you try to fold them in the hot oil.
The Best Frying Oil
You need an oil with a high smoke point because frying occurs at relatively high temperatures. Neutral-flavored oils are best so they don’t overpower the taste of the corn. Excellent options include:
- Vegetable oil
- Canola oil
- Grapeseed oil
- Peanut oil (if allergies are not a concern)
- Avocado oil
Essential Equipment
You don’t need a deep fryer to make professional-grade taco shells. A heavy-bottomed skillet or a cast-iron pan is ideal because it retains heat well. You will also need a sturdy pair of metal tongs to manipulate and fold the tortillas. Finally, have a plate lined with several layers of paper towels ready to drain the excess oil immediately after frying.
Preparing the Oil and Tortillas
Temperature control is the most critical factor in successful frying. If the oil is too cold, the tortilla will soak up the grease and become heavy and soggy. If the oil is too hot, the tortilla will burn before it becomes crispy.
Achieving the Right Temperature
Aim for an oil temperature between 350°F and 375°F. If you have a kitchen thermometer, use it to monitor the heat throughout the process. If you don’t have a thermometer, you can test the oil by dipping the edge of a tortilla into the pan. If the oil immediately begins to sizzle and bubble vigorously, it is ready. If it stays still or bubbles weakly, give it another minute to heat up.
Softening the Tortillas
If your tortillas are cold or feel a bit stiff, it is a good idea to warm them slightly before frying. You can wrap a stack in a damp paper towel and microwave them for 20 seconds, or heat them briefly on a dry griddle. This makes them more flexible and less likely to snap when you fold them in the oil.
Step-by-Step Frying Process
Once your oil is hot and your station is set, you can begin frying. It is best to fry only one shell at a time so you can give it your full attention.
- The Initial Fry
Carefully slide one tortilla into the hot oil. Let it fry flat for about 5 to 10 seconds. You will see small bubbles forming on the surface as the moisture evaporates. Use your tongs to flip the tortilla over. - Forming the Shape
Immediately after flipping, use your tongs to fold the tortilla in half. Do not press it completely flat; you want to leave about an inch of space between the sides so you can actually fill the taco later. Hold the tortilla in this “U” shape with your tongs. - Crisping the Sides
Hold one half of the folded tortilla in the oil for about 15 seconds until it becomes stiff and starts to turn a light golden brown. Then, tilt the shell to submerge the other half, holding it for another 15 seconds. You may need to flip the shell back and forth a few times to ensure both sides and the bottom spine are evenly crisped. - Draining and Seasoning
Once the shell is golden and holds its shape on its own, lift it out of the oil with your tongs. Hold it over the pan for a second to let the excess oil drip off, then place it on your paper towel-lined plate.
Pro Tip: Sprinkle a pinch of salt over the shell immediately while it is still hot. The residual oil will help the salt stick, enhancing the flavor of the corn.
Avoiding Common Frying Mistakes
Even experienced cooks can run into trouble when frying taco shells. Here are a few common pitfalls and how to avoid them.
Managing Oil Absorption
If your shells are coming out greasy, your oil temperature has likely dropped. This often happens if you try to fry too many tortillas in quick succession without letting the oil come back up to temperature. Always check the heat between shells.
Preventing Breakage
If the tortillas are cracking at the seam when you fold them, they are likely too dry. Try the warming method mentioned earlier, or ensure you are using a fresher brand of tortillas. Additionally, don’t wait too long to fold; the tortilla should still be soft when you make the initial bend.
Keeping Shells Warm
If you are making a large batch, the first shells will be cold by the time the last ones are finished. To keep them warm and crispy, place the finished shells in an oven set to 225°F. Arrange them upside down (like a “U”) on a wire rack over a baking sheet to keep the air circulating and prevent them from becoming soggy.
Frequently Asked Questions
Can I fry flour tortillas instead of corn?
Yes, you can fry flour tortillas using the same method. However, flour tortillas puff up much more than corn tortillas and result in a texture that is more similar to a “chalupa” or a puffy taco. They are delicious but have a different flavor profile and a chewier crunch compared to corn.
How deep should the oil be in the pan?
You don’t need to submerge the entire tortilla. About 1/2 inch to 1 inch of oil is usually sufficient. This is considered shallow frying. As long as you can submerge one half of the folded shell at a time, you have enough oil.
Why did my taco shells turn out chewy instead of crunchy?
Chewy shells are usually the result of under-frying or oil that wasn’t hot enough. The tortilla needs to stay in the oil until the bubbling slows down significantly, which indicates that the moisture has been cooked out. If you remove it too early, the remaining moisture will soften the shell as it cools.
Can I reuse the frying oil?
If the oil hasn’t been overheated to the point of smoking and doesn’t smell burnt, you can reuse it. Let it cool completely, strain it through a fine-mesh sieve or cheesecloth to remove any stray bits of tortilla, and store it in a sealed container in a cool, dark place.
How long do homemade fried taco shells stay fresh?
Homemade shells are best when eaten within an hour of frying. Because they don’t contain the preservatives found in store-bought shells, they can become stale or lose their crunch relatively quickly. If you have leftovers, you can try to re-crisp them in a 350°F oven for 2 to 3 minutes.
