Need help converting a recipe for the crock pot please!

[crimedoc1]

Hi all!  I'm hosting Thanksgiving as usual and just realized that I have one more item on the menu than can fit in the oven.  So I thought I could do one thing in the crock pot.  And no... not the turkey!

I'm making a corn casserole and I know that it can be done in the crock pot successfully but I have no idea how long it'll take. Here is the corn casserole recipe I'm using (which is probably already in a jillion places on the internet but just in case....)

Ingredients

• 1 can corn (I use low sodium)
• I can cream-style corn
• 1 box Jiffy corn muffin mix
• 1 stick butter, melted
• 6 oz sour cream (I use reduced fat)

Directions

• Mix all ingredients together
• Pour into greased casserole dish
• Bake at 350F for one hour

As you can see, it's incredible complicated and detailed!  *grin*  Basically, if it takes one hour in the oven, how many hours will it take in a crock pot on low or on high?
