In a large mixing bowl, combine the cooked shredded chicken, shredded cheddar cheese, cream cheese, and sour cream. Mix until well blended and creamy, about 2–3 minutes.

Sprinkle in the garlic powder, onion powder, cumin, chili powder, salt, and pepper into the chicken mixture. Stir thoroughly for about another 2 minutes.

Place a flour tortilla flat on a clean surface. Scoop 2–3 tablespoons of the creamy chicken filling onto the lower third of the tortilla and roll it tightly.

In a large skillet, heat about 1 inch of vegetable oil over medium-high heat until it shimmers, around 350°F. Test readiness by dropping a small piece of tortilla.

Carefully place the taquitos seam-side down in the skillet. Fry for about 2–3 minutes on each side until golden brown.

Using tongs, remove the fried taquitos and place them on a plate lined with paper towels to absorb excess oil.

Serve the crispy Chicken Taquitos warm with toppings like salsa, guacamole, and chopped cilantro.
