Another great squash/zucchini recipe!

I also combined squash and zucchini and used sharp cheddar since that's what I had on hand. Since my garden is loaded with tomatoes, they also made their way into this dish. It's a keeper!

My family devoured this recipe! It will be a special occasion staple for me from now on. The only tweaking I did was add another half cup of cheddar and 1/2 tsp more salt. This is merely personal preference. The recipe can be followed exactly and it will still be delicious.

Dish was very good except for one thing: way too many breadcrumbs on top! I thought I may have made a mistake, so I double checked the recipe and indeed it said 1.5 c breadcrumbs for the topping. I will definitely make this again but will use about half the amount of breadcrumbs in the future.

This is now my standard go-to recipe for squash casserole. Delicious with the combiniation of cheddar and parmesan. I didn't use as many bread crumbs on top as what was called for and it turned out perfect.

I fixed this for New Years dinner and everyone was just okay. Try Nana's squash casserole on for a true 5 star casserole.

This is so yummy! Recipe makes a huge amount so avoid leftovers by splitting the recipe in half. If you have too many leftovers of this, you might be tempted to eat it for breakfast! It's that good!

Very yummy! I did add some salt, and I thought it was definitely not too many breadcrumbs. When the casserole is placed in the size dish the recipe calls for, the breadcrumbs don't even cover the entire top. I personally will make a little more for the top next time. Will be making for Christmas!

Unbelievably good; my bride rewarded me with desert.
