When my garden is overflowing with zucchini, crook necks, and other summer squash, I cook it all up into this fabulous squash casserole. This dish is loaded with tender squash, creamy sauce and of course, plenty of melted cheese. It’s the perfect side dish to feed a crowd and is great as part of a holiday meal.

How do you make squash casserole?

This recipe starts with sliced yellow squash, which is cooked with onions in butter until tender. While the squash is cooking, it’s time to make the creamy sauce. This homemade sauce is a blend of milk and cream that’s seasoned with herbs and spices. The cooked squash is tossed in the cream sauce along with plenty of cheddar cheese. The finishing touch is a layer of buttered cracker crumbs and more shredded cheese. Add a sprinkling of fresh chives and you’ll be ready to eat.

Tips for squash casserole

  • Traditional Southern squash casseroles often use mayonnaise or sour cream to make the squash creamy. That being said, I feel that this homemade cream sauce has a ton more flavor, it’s definitely worth taking a few extra minutes to make.
  • I use cheddar cheese in my squash casserole, but mozzarella or Monterey Jack cheese would also work well.
  • You can toss the cooked squash in the sauce and cheese, then cover and refrigerate the casserole for up to 6 hours. Add the cracker crumbs and final layer of cheese right before you put the casserole in the oven.
  • I like the flavor of fresh chives as garnish for this dish, but other great options include parsley, thyme or basil.
  • I typically use Ritz crackers for the topping, but any variety of buttery crackers will work just fine.
  • This casserole can also be made with zucchini or patty pan squash.

What does yellow squash look like?

Yellow squash is also known as crook neck squash. It tapers at the neck which is where it gets its name from. There are other types of yellow squash such as yellow zucchini, but I recommend using crook neck squash for this dish, as it has the best flavor.

Do you peel yellow squash?

I recommend leaving the peels on your squash for this casserole, the peel is what will keep the slices of squash intact during the cooking process. In general, the peels of summer squash are thin and edible, so there’s no need to remove them. The peel also adds nice color!

This squash casserole is great for summer entertaining, but is also a great addition in the cooler weather months for holidays such as Thanksgiving. That combination of rich creamy squash and crunchy crackers just can’t be beat.

      Delicious! I made it gluten free using gf flour and substituting ‘ruffled’ chips for the crackers. Love that I can make this ahead!

      I have previously tried another recipe that was a flop. I loved this one and will come back to it again. With all the squash coming out the garden … I’m sure its going to be sooner, rather than later.

      out of necessity I replaced the heavy cream with condensed cheese..I also added chunks of eggplant because it was going to go bad came out great because the cheese was thicker than cream I might add more milk next time
