Recipe by Parsley

A good use for a garden full of yellow squash or green (zucchini) squash or both!

My husband and I both thought this was very tasty! We don't like celery, so I used chopped carrot instead, and added egg as a binder as previously suggested. It was a great way to use up an overgrown squash (I didn't use the pithy center part).

Ingredients Nutrition


  1. Preheat oven to 350. Lightly grease/spray a casserole dish and set aside.
  2. In a large skillet, melt the butter. Add the squash, celery and oniona and saute in the butter for about 2-3 minutes, just until they are softened and barely tender. Do not overcook.
  3. Remove from heat.
  4. Stir in the sour cream, cheddar cheese, pepper and (if needed salt) and bacon.
  5. Mix well and place in the casserole dish. Sprinkle Parmesan over the top and bake at 350 degrees for about 30 minutes or until lightly brown on top.
