The easiest way I’ve found to make the chicken for my freezer food bases is to cook it in bulk in the crock pot. It is easy and when I slow cook it for hours it makes the most tender shredded chicken you can imagine. You don’t even have to use a fork, it falls apart in your hands. It also makes a great broth to use in other recipes or to freeze for later!
I buy my chicken breasts in bulk, but I’m toying with the idea of using thighs instead since they’re cheaper and I’m using them in recipes rather than by themselves. I buy them frozen but whatever chicken you have is fine. I use boneless always. I hate pulling stuff off the bone. Again, personal preference.
I fill my crock pot nearly to the top with frozen chicken. Breast, thighs, tenders, whatever suits your fancy. I then fill it to the top with water and add one can of chicken broth just for extra flavor. I add salt, pepper, and garlic and cook on high for about 5 hrs or so. What you get is the most tender shreddable chicken and it’s delicious. You can freeze it just like this or do what I do and use it in your base recipes.
I pull the amount of chicken I need for the recipe I’m working on, shred it into a bowl, add the other ingredients, stir then bag and freeze. Easy peasy!
