Wondering how to cook a squash casserole? It’s quick and easy! Start by preheating your oven to 350°F and butter a 1½-quart baking dish (or coat with nonstick cooking spray) and set aside.
Bring squash, onion, water and salt to a boil in a saucepan. Cover pan and simmer until squash is tender, about 20 minutes.
Drain squash thoroughly, then mash. Add milk, eggs, flour, 1 tablespoon of melted butter and pepper, mixing everything together.
Reserve about 3 tablespoons of shredded Cabot Sharp Cheddar cheese and mix remainder into squash. Transfer squash to prepared baking dish.
Bake for 30 minutes, or until a knife inserted in the center comes out almost clean.
Toss bread crumbs with remaining melted butter while squash bakes. Sprinkle over casserole, then sprinkle with reserved cheese. Return to oven for about 5 minutes, or until crumbs are golden and cheese is melted.

I’ll be making this until zucchini season ends!
I made this with mixed yellow squash and zucchini. For the topping, lightly butter four slices of bread on both sides and cut them up, then scatter over the top, add the last of the cheese, and bake. Delicious.
Tried it with cornmeal instead of flour, prefer flour. Using all zucchini was a bit acidic, yellow squash adds butteriness. Can easily accommodate other veggies.
I made this but made a white sauce then added the beaten egg. Also have a lot of tomatoes so slice some and layered them in. This was very good.
This was delicious thank you
This is the best squash casserole ever! I modified it by roasting the squash and onions and by adding fresh jalapeno.
Neither my husband nor I grew up eating squash, so I am super excited to find this delicious recipe to use CSA yellow squash…the cheese makes it awesome…we both had seconds, with leftovers for tonight! The casserole was super easy, and I have printed it out to keep in my recipe notebook! Thanks!
A dear friend dropped off a bag of yellow and zucchini squash.
It was just a bit over two pounds!
I used this recipe and it was outstanding!
I had it as a main, and it was filling and delicious. It will be a keeper for this family. I think it also lends itself to the addition of other summer veggies -green beans, tomatoes, broccoli, etc.
Try any other garden vegetable with the squash, mine came out great I submitted the yellow squash for zucchini.
I made the Summer Squash Casserole but used Gluten Free Rice Flour and used 4 tablespoons because it is a finer flour and I didn’t use bread crumbs/butter for the topping. It was delicious and I am make a copy of the recipe for my granddaughter with the changes.
This was great. We switched it up and used Hot Habanero Cheddar for a nice kick.
