Why This Recipe is Best

Southern Squash Casserole is a classic dish that has been around a long time. Most folks like to use cream of mushroom soup to make it, but I promise you'll love this new version that has no MSG or artificial ingredients!

The addition of sour cream, along with mayonnaise and eggs, creates a custard consistency that is made even better by including two cheeses.

I know you've been making this dish for years, but y'all...this recipe is worth a second look. Folks tell me they'll never go back to the old way of making it after trying this version!

Yellow squash is the best squash to use in a casserole because the seeds are tender and do not have to be removed. You can also eat the skin, which makes yellow squash a great choice for this recipe.

Any type of meat tastes great alongside this dish. Try pork tenderloin, glazed ham, pot roast, and fried chicken to name a few!

Can squash casserole be frozen?

Expert Tips

Sautéing onions and squash in butter gives this dish its robust flavor.
Adding a dash of garlic salt to the squash while sautéing adds depth.
Use two cheeses for best results. Make sure one of them is parmesan.
Feel free to substitute zucchini for squash if you wish, but the flavor will change.
