I haver another suggestion for Kugel. My sister makes it this way and it’s absolutely delicious!
Very simple. Make your Kugel mixture in the usual fashion. Pour the whole mixture (as it is – raw) into a 1 or 2 gallon plastic bag. Tie it on top and place the whole bag as is into your Cholent. Make sure to poke some holes with a fork on the TOP PORTION of the bag to let heat escape, otherwise the bag might blow up.
The kugel will not come out nice and flat. But it will be oh-so delicious!
p.s. I’ve never tried in a regular pot. We use a crock-pot.
