How To Make Squash Casserole

This Southern Squash Casserole is very easy to make.  The hardest part of the whole recipe is slicing the squash. I like to use a handheld mandoline slicer to slice the squash into thin slices. Having all the slices the same thickness helps the squash cook evenly.  It also only takes a minute to slice the squash with the handy dandy handheld mandoline slicer.

After you slice the squash, you are going to quickly saute it in a skillet with some butter, garlic and onion. Once the squash is tender, you are going to transfer it to a colander to drain the excess liquid. Press down on it to really get all that liquid out. You don't want a runny casserole.

Once the squash has drained, finish mixing the remaining ingredients and transfer to a baking dish and top with melted butter, cheese, and crushed Ritz crackers.

Can Squash Casserole be Made Ahead of Time & Frozen?

Absolutely! This Southern Squash Casserole can be made ahead of time and refrigerated or frozen until ready to bake. Just assemble the casserole and refrigerate or freeze before baking. If baking after being refrigerated overnight, you may need to add a few minutes to the cooking time. If you are freezing this casserole before baking, thaw the casserole completely and bake as directed below.

You can also freeze the leftovers. When ready to reheat, just thaw and pop in the microwave for a quick side dish.

  1. Saw where you said it would freeze well. I have found that the squash gets watery when frozen. Do you not have a problem with that? Also, would you freeze uncooked or after being cooked? Thanks

    1. I always make sure to drain the squash really well before assembling the casserole. You can freeze this cooked or uncooked. I prefer uncooked. I thaw it completely and then bake as directed.
