Heat a large skillet over medium-high heat and add the ground beef. Using a wooden spoon, break it apart as it cooks, ensuring even browning. Sauté for about 8 minutes, stirring occasionally, until the meat is fully cooked and no pink remains. Sprinkle in the taco seasoning, followed by a tablespoon of water, stirring continuously. Allow the mixture to cook until it thickens and becomes fragrant, creating a flavorful coating around the beef. Once done, remove from heat and set aside.

In a separate skillet, pour in enough vegetable oil to create a ¼-inch layer and heat it over medium heat. When the oil is shimmering, carefully place a tortilla into the pan, letting it fry undisturbed for about a minute until golden brown and crisp. Flip and cook the other side, ensuring an even crunch. Once done, transfer the tortilla to a plate lined with paper towels to absorb excess oil. Repeat the process with the remaining tortillas, adding more oil as necessary.

Evenly distribute the seasoned beef among the crispy tortillas. Finish by layering your choice of toppings, such as crisp lettuce, shredded cheddar, cool sour cream, fresh cilantro, vibrant pico de gallo, or zesty salsa. Serve immediately while warm for the ultimate crispy taco experience.
