I will cook a whole bag of frozen chicken breasts in my crock pot. I just put them in layers, season each layer with salt, pepper, etc put the lid on and cook them on high for about 5-6 hours. If they are thawed it might not take as long. When done, I let them cool and portion them out 2 to a bag. That's 1 each for me and my husband. If I need more for a recipe, I thaw out bags accordingly. Also though, they're already cooked and ready to eat so if you are hungry get it out and thaw in the microwave.
