Recipe by Mainely Debbie
READY IN: 2hrs 45mins
SERVES: 10-12




  • Slice squash in 1/2 inch slices.
  • Slice onion into thin slices and then each slice into 4.
  • Slice tomatoes in half then each half in half and then in half again.
  • Mix the squash together with the onion and fry on medium heat using 4 tablespoons butter for each batch; I do 4 batches, 1 at a time so you don't overload frying pan; make sure not to brown the squash, cook about 5 minutes each batch, add quarter of tomatoes and mix.
  • Layer vegetable in a single layer in a large casserole dish that has been sprayed with Pam. Coat the top of vegetables with 4 oz. parmesan cheese, repeat layers ending with parmesan cheese.
  • Cover and bake in a 350 oven for 2 hours or until squash is done.
