In a large mixing bowl, combine the shredded chicken, buffalo sauce, softened cream cheese, shredded cheddar cheese, and chopped green onions. Stir the mixture vigorously until all ingredients are evenly blended and the mixture is creamy.
If you choose to bake the taquitos, preheat your oven to 400°F (200°C). Alternatively, if frying, pour oil into a deep skillet and heat it over medium-high heat.
On a clean, flat surface, take one flour tortilla and lay it out. Spoon approximately 2 tablespoons of the buffalo chicken mixture onto one end of the tortilla.
Tightly roll the tortilla around the filling, folding in the sides as you go to secure the ingredients inside. Make sure it's snug but not overly tight to avoid splitting.
Continue this rolling method with the remaining tortillas and filling until all are prepared.
For Baking: Arrange the taquitos seam-side down on a baking sheet lined with parchment paper. Lightly spray their tops with cooking spray for a golden finish. Bake in the preheated oven for 15-20 minutes or until they turn a lovely golden brown and become crispy.
For Frying: Carefully place each taquito seam-side down in the hot oil. Fry for about 3-4 minutes on each side or until they achieve a perfect golden brown color. Use a slotted spoon to transfer them to a plate lined with paper towels to absorb any excess oil.
Allow the taquitos to cool for a few minutes before serving to let the filling set slightly and avoid burns.
Notes
Serve with salsa and sour cream for dipping. Drizzle extra buffalo sauce on top for added flavor.
