How to Make Southern Squash Casserole
Start by preheating your oven to 350°F (175°C). Grab your trusty baking dish and give it a quick spray with nonstick cooking spray. This casserole loves being pampered!
Prepare your squash by washing it thoroughly and slicing it into thin rounds. You want them tender but not mushy—think of them as little yellow coins ready to join the party!
Next up, chop the onion finely. Sautéing those bits in a skillet with some butter until they turn translucent releases their sweet aroma that makes your kitchen smell divine.
In a large mixing bowl, combine those lovely sautéed onions with your sliced squash. Add in cream of mushroom soup and beaten eggs, stirring everything together until well combined. You want each piece of squash coated in that creamy goodness!
Now comes the fun part: fold in half of the shredded cheddar cheese. This melty magic will blend perfectly during baking!
Transfer this luscious mixture into your prepared baking dish. Sprinkle the remaining cheddar cheese on top followed by an even layer of breadcrumbs. Drizzle melted butter over everything—it’s like giving your casserole a warm hug!
Finally, pop it in the preheated oven for about 30-35 minutes or until golden brown and bubbly. You’ll know it’s done when your kitchen is filled with that irresistible cheesy aroma!
Once out of the oven, let your casserole rest for about 5 minutes before serving. Trust me; those few moments are worth waiting for as all flavors settle down nicely.
Enjoy this Southern Squash Casserole alongside grilled meats or simply on its own as a delightful main course!
