1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or a silicone mat for easy cleanup.
2. In a mixing bowl, combine the shredded chicken with the spices, cheese, and any optional ingredients you fancy, such as cilantro or onion. Give it a good mix until everything is well incorporated.
3. Warm the corn tortillas in the microwave for about 30 seconds, wrapped in a damp paper towel, to make them more pliable and avoid cracking while rolling.
4. Lay a tortilla flat on a clean surface, spoon about 2 tablespoons of the chicken mixture onto the lower third of the tortilla, and roll it tightly around the filling.
5. Place the rolled taquito seam-side down on the prepared baking sheet. Repeat with the remaining tortillas and filling.
6. Lightly coat the tops of the taquitos with cooking spray or brush them with oil to achieve a crisp exterior.
7. Bake in the preheated oven for about 15-20 minutes or until the taquitos are crisp and golden.
8. Let them cool slightly before serving, as they will be hot!
