Place the chicken in the Instant Pot on the trivet in the Instant Pot. Sprinkle the taco seasoning evenly over the chicken breasts. Pour 1 cup of water into the bottom of the Instant Pot. Place the lid on the Instant Pot and close the valve. Set the Instant Pot to high pressure for 10 minutes.
After the 10 minutes are done, manually release by opening the valve. Open the Instant Pot lid after all the pressure has been released.
Remove each piece of chicken, and shred. After shredding, put it in a large bowl along with the sour cream and salsa. Mix well.
Pour out the water from the Instant Pot, and wipe the pot, as well as the trivet. Once cleaned, add 1 cup of water and turn the Instant Pot on steam mode. When the water is bubbling, place a tortilla on the trivet.
Steam one side for about 1 minute, flip, and steam the other side for about 1 minute.
After the tortilla has steamed, place about 2 tablespoons of the chicken mixture in the tortilla across the middle. Roll, then set aside. Continue with the next taquito.
Pour oil into a frying pan about halfway. Set your stove to medium heat. Once the oil is hot, place the taquito fold-side down until golden brown. Flip to fry the opposite side until golden brown. Continue until all are cooked. Of course, you can also cook these in the air fryer or oven! Simply preheat your air fryer to 375°F. Place taquitos into air fryer and cook for approximately 8-10 minutes.
Serve with your favorite sides, such as cilantro, shredded cheese, salsa, and sour cream! Enjoy!
