Warm the tortillas. Stack corn tortillas, then wrap in a damp paper towel. Microwave for 15-30 seconds, or until warm.
Prepare the filling. Place shredded rotisserie chicken in a large mixing bowl. Add 1 cup shredded cheese, 1 tsp cumin, ½ tsp garlic powder, ½ tsp chili powder, ½ tsp onion powder, ½ tsp kosher salt, and ¼ tsp black pepper. Squeeze the juice of 1 lime on top. Stir until well mixed.
Assemble taquitos. Spoon about 2 tablespoons of the chicken and cheese filling onto the bottom ⅓ of a warm corn tortilla. Roll tightly around the filling, creating a cylinder. If needed, you can secure it with a toothpick. Store seam-side down until ready to fry.
Fry until crispy. In a large, deep skillet, pour enough neutral oil to come about ½-inch up the sides. Warm over medium-high heat until the oil reaches approximately 350°F (175°C). Carefully lower a few taquitos into the oil, seam-side down. Fry in batches, making sure not to overcrowd the pan. Cook each side for about 2-3 minutes, or until golden brown and crispy!
Drain excess oil. Using tongs, transfer the taquitos to a paper towel-lined wire rack. Repeat with remaining rolled tortillas.
Garnish, then serve! Transfer the taquitos to a platter, then garnish with your favorite toppings: I like pico de gallo (or salsa), a dollop of sour cream, crumbled cotija, sliced radishes, and fresh cilantro. Serve with lime wedges on the side. Enjoy!
