Cheesy Squash Casserole

Cheesy Squash Casserole is simple and easy to prepare and is the perfect family dinner food. It graces the tables during holidays and is almost synonymous with potluck dinners. This Southern Cheesy Squash Casserole is certainly a comfort dish: yellow squash, eggs, cheese, half and half. How could it get any better?

Cheesy Squash Casserole is always a welcomed dish!

Fresh is Best

Really, there couldn’t be a dish easier to make with all the overflow of squash that gets harvested out of our summer garden. Although cheesy squash casserole is best to make with fresh squash, it is delicious with the squash I “put up” (freeze) from our summer harvest.

When making squash casserole with fresh squash, I often get my kids involved in slicing the squash into rounds and coarsely chopping the onion. After boiling,  draining, and adding them 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!
