    The last few years I have been trying to learn all the southern favorites that my husband grew up on. As they say, the way to your man’s heart is through his stomach. I can vouch for that big time, it’s been working great for the last 7 years or so. My first taste of this Southern Squash Casserole came in one of our favorite spots in the Golden Isles of Georgia. I remember it came in small individual ramekin like bowls, and one spoon into that cheesy squashiness and I said “how can your regular vegetable get to that level of yum??” My husband just said “welcome to the South.”

    This is a dish you will find in those small little diners or at any of those family get togethers like Thanksgiving, Christmas or just a summer potluck. It’s everybody’s favorite!

    Like so many holiday side dishes, it’s pretty quick and simple to put together. All you have to do is cook the yellow squash a little, make the cream sauce, marry them together in your casserole dish, put on a crumbly topping and bake it. Sound easy? First, a few tips to ensure you end up with a mighty tasty dish on your table:

    Tips for perfect Southern Squash Casserole

    Tip #1: It’s very important to get as much liquid out of the squash during the initial cooking as possible to prevent a watery casserole. Remember, these squash have a very high water content, so when you sauteé them discard the liquid from the pan. To make sure most of it is gone, rest the sauteéd squash in a colander for 10 minutes to drain out any remaining liquid.

    Tip #2: Slice your squash evenly and don’t overcook it. Avoid browning them. You just need to make them a little bit soft, otherwise you may end up with a mushy casserole.

    Tip #3: Try to stick with Ritz crackers, they are super buttery.

    Tip #4: Gently fold the sauce mixture in your sauteéd squash as you don’t want to break the squash up.

    Add sauce to squash and gently stir until mixed.

    Crush Ritz crackers and mix with 2 Tbsp melted butter. Spread this mixture over the top of your casserole.

    Bake at 350°F for 20-25 minutes uncovered until your casserole is a little bubbly and the topping is lightly browned.

    Can I make Southern Squash Casserole ahead of time?

    Absolutely! This casserole is very holiday friendly, as it freezes great. You can make it few days back, minus the Ritz crumble. Take it out to thaw the day before eating and leave in the fridge overnight. Add the Ritz topping right before baking. Voila, one dish you don’t have to put much effort into on the big day!

    We always have these squash a plenty in our refrigerator. Try this casserole one of these days. You can do the same with zucchini or mix and match with both. If you want a complete, one-pot meal, how about adding some shredded rotisserie chicken along with sauce. Brilliant, isn’t it?? Let me know if you try this for your special Turkey spread this year, or for a regular weeknight meal with my shredded chicken idea!!
