Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper. (This keeps the taquitos from sticking and makes clean up a little easier.
In a large bowl, combine the shredded chicken and buffalo sauce, mixing until the chicken is evenly coated.
2 cups cooked shredded chicken, 1/2 cup buffalo sauce
Then, fold in the cheeses, green onions, and celery.
1 cup cheddar cheese, 1/4 cup blue cheese crumbles, 1/4 cup green onions, 1/4 cup celery
Warm 2-3 tortillas at a time in the microwave for about 20 seconds to make them pliable, then spoon about 3 tablespoons of the buffalo chicken filling onto each tortilla, spreading it evenly along the center.
12 6" flour tortillas
Roll up each tortilla tightly, securing it with a toothpick if needed, and place them seam-side down on the prepared baking sheet.
Repeat with the remaining tortillas until all twelve are ready. Lightly spray the taquitos with cooking spray to help them crisp up in the oven. (You can also brush them with olive oil or melted butter, if you prefer).
Cooking spray
Bake for 15-18 minutes or until the taquitos are golden brown and crispy.
Remove from the oven, let them cool for a few minutes, and serve with your favorite dipping sauce. (We light these with ranch or blue cheese dressing.)
