Cook on low heat for 5-6 hours or high for 3-4 hours. The time may vary between crockpots, so towards the end of the cooking time, check the polenta to make sure it's fully cooked. It should have a soft, smooth texture, and not feel grainy. Also, it's best to stir the polenta every hour or two to make sure it doesn't stick to the sides of the crockpot
Remove the chicken and shredded into small pieces
Stir both cheeses into to the crockpot, cover with the lid, and leave the crockpot on warm for 30 minutes
