Begin by shredding the cooked chicken into small, even pieces using your hands or a fork, ensuring the pieces are not too large so they can absorb the creamy mixture properly.
Place a large skillet over medium heat and add the shredded chicken, allowing it to warm up gently for a few minutes while stirring occasionally to prevent sticking.
Add the softened cream cheese and mayonnaise directly into the skillet with the chicken, then reduce the heat slightly and begin stirring slowly as the cream cheese melts and blends into the chicken.
Continue stirring until the mixture becomes smooth and creamy, making sure there are no large lumps of cream cheese remaining.
Add the shredded cheddar cheese along with garlic powder, onion powder, paprika, salt, and black pepper, mixing everything thoroughly so the cheese melts evenly and coats the chicken completely.
Allow the mixture to cook for another 2–3 minutes, stirring continuously until it reaches a thick, creamy consistency without becoming dry or overheated.
Remove the skillet from heat and let the mixture sit for a minute to slightly thicken, making it easier to handle when assembling the tacos.
Take your low-carb tortillas or lettuce leaves and place a generous portion of the creamy chicken mixture in the center of each one, being careful not to overfill.
Add any optional toppings such as chopped green onions, diced tomatoes, or cooked turkey or beef bacon for extra flavor and texture.
Serve immediately while warm, enjoying the creamy, cheesy filling wrapped in a low-carb taco for the best taste and texture experience.
