  1. Make lasagna first. Boil for 8 minutes (slightly hard); rinse with cold water, drain and let sit. Make mashed potatoes; saute 5 onions and 1 to 21 1/2 cups margarine on low heat until onions are soft. Grat e Cheddar cheese and add to potatoes; add onions and butter mixture. (Leave a little out to spread on top when through layering.) In 9 x 13-inch pan, layer butter on bottom of pan, then lasagna noodles, then potato mixture. After 3 layers (lasagna on top), spread remaining butter and onions on top.
  2. Cover with foil and bake at 350 degrees for about 30 to 40 minutes.
  3. Note: The layers of the potato mix should not be more than 1/2-inch deep.

Great recipe. I added salt, pepper, sugar, thyme & rosemary to the onions and deglazed the pan with white wine. I'm not big on butter so I use herbs and wine to get the taste.
