Cheesy Squash Casserole

This cheesy squash casserole 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 Southern Cheesy 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!

The great thing about this dish is that it 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. By adding cumin, or thyme, or using Swiss cheese, you’ve got an entirely different flavor from practically the same dish!

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! They soak up the flavors of sauces thereby lending themselves to all kinds of awesome variations. They’re incredibly healthy and versatile.

    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.
