Step 1: Preheat Oven : Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.
Step 2: Prepare Filling : In a mixing bowl, combine shredded chicken, shredded cheese, cream cheese, chili powder, garlic powder, onion powder, cumin, salt, and pepper. Mix until ingredients are evenly incorporated and creamy.
Step 3: Assemble Taquitos : Warm tortillas slightly to make them pliable. Spoon about 2 tablespoons of filling onto the lower third of each tortilla. Roll tightly, tucking in edges as you go, to form a mini taquito. Place seam-side down on the prepared baking sheet.
Step 4: Prepare for Baking : Brush or spray the tops of the taquitos lightly with olive oil for crispiness. Optional: Sprinkle a little extra cheese on top for extra flavor.
Step 5: Bake : Bake for 15–20 minutes, flipping halfway if desired, until taquitos are golden brown and crispy.
Step 6: Serve : Transfer to a serving platter. Serve hot with sour cream, salsa, guacamole, chopped cilantro, or lime wedges.
