Step 1: Preheat your oven to 400°F (200°C) to ensure a crispy exterior.
Step 2: In a mixing bowl, combine cream cheese, Buffalo wing sauce, and ranch dressing until smooth. Add chicken, cheese, blue cheese (if using), green onions, and black pepper. Mix well.
Step 3: Lay out tortillas, place 2-3 tablespoons of filling in the center, and roll tightly, tucking in the sides to secure.
Step 4: Line a baking sheet with parchment paper and arrange taquitos seam-side down. Optionally, spray or brush with olive oil for extra crispiness.
Step 5: Bake for 15-20 minutes until golden brown and crispy. Watch closely to prevent burning!
Step 6: Let cool slightly before serving warm with ranch dressing on the side.
