I have the GREATEST neighbors!  I live in a town home and my neighbor beside me loves to grow vegetables.  Lucky me!  His wife called the other day and told me to come to the back porch because they had two big bags of squash for me. So I just had to make this Cheddar Squash Casserole.

Since I’m updating this post I USED to have the greatest neighbors at that town home I lived at.  The day I got that huge bag of fresh squash I was so excited and made this casserole.  It has been on every holiday table and potluck ever since!

I slice my squash thin and sauté in butter, along with some chopped Vidalia onions until they’re soft (about 10-12 minutes).  Drain off the juices in a colander and press with the back of a spatula or a big spoon.

Transfer the cooked squash and onions to a large bowl.  Add some shredded cheddar cheese, grated Parmesan cheese, sour cream, salt and pepper… then stir it all up with a big spoon.

Top with a sleeve of crumbled buttery crackers and bake for 15 to 20 minutes, or until crackers are golden brown and the edges of the casserole are bubbly.  Your family will thank you!  🙂

    Made this August 13, 2017. Mixed half yellow squash and half shredded zucchini from my freezer, and topped with crushed and buttered garlic croutons. Delicious! Plan to make another time for guests.

    This looks so good! Perfect time to start testing recipes for Thanksgiving! As such, I am also planning to make pork tenderloin to accompany this dish. Question for you – if the pork tenderloin needs to be cooked at 425, how can I adjust the baking time for this dish? Any input would be greatly appreciated!

      Hi Marcie, I’ve never adjusted the temperature or baking time of this squash casserole so I can’t say – it’s so good that I never want to risk adapting/modifying it in any way!

    This is SO good! I was looking for one that didn’t call for mayo – because that’s how I have always made it. This one is way better than the mayo version. 🙂 I didn’t have any crackers because my 2 year old scarfed them all….so I used crushed croutons instead. Fabulous!

    Drain off the juices in a colander & press with the back of a spatula or a big spoon. You don’t want the casserole to be all watery, do you? I think just add another sleeve of crumbled crackers to absorb this delicious juice
