Add chicken to a pot and fill with water to cover. Add in 2 TBSP of taco seasoning to the water. Boil chicken on medium heat until the chicken is done.
Place chicken on a plate to cool. Once it is cool to the touch. shred the chicken into small pieces.
Put shredded chicken in a mixing bowl. Add in sour cream, remaining taco seasoning, and shredded cheese. Stir until completely combined.
Heat tortillas in microwave or in the oven until warm and flexible. They will crack if you skip this step.
Scoop a spoonful of mixture into the center of the tortilla and wrap them up tightly. Continue to work through all the tortillas until you have used all your chicken mixture.
Place on a large baking sheet covered in aluminum foil and spray with cooking spray, seam side down so they don't unravel. I don't use cooking spray from the grocery store any more. I have a spray bottle that I add avocado oil to for all my cooking spray needs.
Once all tortillas have been filled and wrapped, spray or drizzle with a little olive oil or avocado oil for browning.
Bake at 400° for about 15-20 minutes or until the tops of the taquitos are golden brown and they have baked to crispy perfection. Add extra minutes to cooking time if needed, cooking times will vary. Let cool slightly then eat with your favorite dipping sauce!
Notes
