Cheesy Squash Casserole

This cheesy squash casserole recipe is simple and easy to prepare, making it the perfect family dinner food. Not only does it grace the tables during holidays, but it is almost synonymous with potluck dinners.

Cheesy Squash Casserole is always a welcomed dish!

This classic Southern squash casserole is certainly a comfort dish: yellow squash, eggs, cheese, half and half. How could it get any better?

Fresh is Best

Really, you couldn’t find a dish easier to make with all the overflow of squash from a summer garden. Although I like this cheesy squash casserole best with fresh squash, it is also delicious with the squash I “put up” (freeze) from our summer harvest.

When making squash casserole with fresh squash, I often enlist my kids’ help. They slice the squash into rounds and then coarsely chop the onion.

After boiling and draining the squash and adding the rounds to the cheese and milk mixture, you’re almost done. All that’s left is topping the casserole with buttery crunchy Ritz crackers and baking it to perfection.

Creamy and crunchy, this buttery and cheesy squash casserole bakes to perfection.
Simple to make and delicious to devour!

Spice it Up!

How do you give squash more flavor? Spice it up! With its cheesy filling and buttery cracker topping, this dish delivers amazing flavor. Just by changing spices, herbs, or even cheeses, you can feast on a unique dish with ultimately the same base of squash, cheese, eggs, and milk. Sprinkle on cumin or thyme to taste, add Swiss cheese or even sour cream, and you’ve got an entirely different flavor from the same basic squash casserole!

How do you keep squash casserole from getting watery?

The high water content of summer squash, compared to starchier winter counterparts like butternut squash, makes it very low calorie. However, all that liquid can make a squash casserole soggy if not properly drained before baking. Pre-cooking the squash in the stock pot helps in this recipe. Here is another easy step that adds only a few minutes to your prep time. When you remove the squash from the pot, let it drain in the colander for about 10 minutes. Then gently press all the water through the colander.

What do I Serve with Squash Casserole?

I love to serve cheesy squash casserole with Roasted Chicken and Sausage, or my Venison Meatloaf.  Of course, it’s always alongside the turkey and dressing at my Thanksgiving and Christmas Table too! The holidays just wouldn’t be the same without it.

Whatever you do, enjoy this dish anytime of the year with people you love! Or even those you don’t – you may end up loving them after dining on this exquisite dish!

Squash Boats are simple to make and super healthy. Squash is such a versatile vegetable that lends itself to frying, grilling, sautéing, or even used as noodles!

    Love this, By the way where did you get your red pot holders, i have them but I need new ones, Please let me know, thank you, Gaile from TX

    1. I think I got the potholders at Bed Bath and Beyond. They have been great. Not too thick. I don’t like it when I can’t wrap them around the casserole.

    Stacy our summer squash is abt ready to pick a few for your casserole. Yours looks so delicious. I’ve never added cayenne pepper to mine though I’m going to add some soon when our squash is ready to be made. Your recipes are some that my little family love. Thanks for sharing

  3. let me start this by saying I’ve never cared for squash but I made this recipe for my husband and to my surprise, I actually liked this very much. It was my 1st attempt at a squash recipe and my husband was very happy and said it was a delicious and a keeper recipe. Thanks for the help.

    1. That makes my day!! I’m so glad you liked it!!

  4. Do you drain the water off of the squash ?

    1. 5 stars
      Hi Shea! Yes, drain the squash first and let the water evaporate from the squash. This will create a smooth, delicious casserole.

  5. I gave this a try and really liked it. It worked out well, the squash I took out of my garden were a little old, but running them through the food processor made the difference. By in large prep was easy and straight forward. I will say that I added a can of HOT rotel, just to give that southwest kick. I will remember your recipe and use it again.
