Hi Paula,

Thanks! They turned out great! I had to make them in the crockpot because I wanted them ready to go when we got home from church this morning. Fantastic with ham and asparagus.
Hi, Kim ~ Yum!! This sounds delicious! Can’t wait to give it a try. Thanks for sharing!
How long and what temp in the crock pot?
Candice, I have not made this in a crockpot, this recipe is for baking in an oven. I do not know how long or what temp it would do well in a crockpot.
Kim
This looks really tasty!! thanks so much for stopping by!!
Hugs,

I love how comforting these are! Cheesy potatoes are my total weakness, so I don’t think a pan would be safe near me – YUM! :)
