Add chicken to a slow cooker. Season with salt, pepper, paprika, garlic powder, onion powder, and dried parsley. Add minced garlic, chopped onions, and buffalo sauce to the crockpot and stir everything together.
Cook on low for 4-6 hours or on high for about 3 hours, or until the chicken reaches an internal temperature of 165 degrees F.
Remove the chicken from the slow cooker and place it in a bowl. Shred the chicken using a hand mixer or two forks. Add more buffalo sauce to taste if you want more of the buffalo sauce flavor.
Add 1/4 cup of oil to a skillet and heat over medium-high heat.
Add a couple of white corn tortillas to your skillet. Top them with shredded mozzarella cheese and a scoop of the buffalo chicken.Fold the tortillas over and cook on both sides until golden brown and crispy. Flip them multiple times if needed while frying them.
Work in batches repeating these steps until all of your tacos are made. If your skillet gets dry you can add another 1/4 cup of oil if needed. While frying the tacos you can place them on a wire rack on a sheet pan to help drain the grease and place them in the oven to keep them warm.
Serve the Buffalo Chicken Tacos with ranch, sour cream, or blue cheese. Enjoy!
