House Home And Garden

What is the best way to store home grown Onions for longer than a few days?

I have been given a whole bunch of Onions from a friend’s home garden and I don’t usually eat Onions fast enough to be able to finish them without losing some to spoilage.

I have been told that all I have to do is peel them and cut off the roots and pop them in the refrigerator in a Tupperware box. Any other methods?

Failing that, any recipies for onion casseroles (I remember something with lots of cheese on top) or summer salads?

My aunt made these a while back and I asked her for the recipe.. She said it was in the Better Home & Gardens cookbook. I thought I had this cookbook but it must have gotten lost when I moved. Does anyone have a copy of this recipe?

Thanks!
