If you’re looking for a delicious, classic southern side dish, then you have to try this Easy Squash Casserole! Beautiful yellow squash is layered into a cast iron, topped with a crunchy, cheesy crust and then drizzled with a light butter sauce to create an irresistibly flavorful dish that everyone will love.

I’m spending the week at the beach and brought my trusted cast-iron skillet with me. You might say I’m picky, but I like to think I’m smart. Good equipment means a better outcome with your special recipes. It’s worth packing up a few of your tools!

I love any kind of squash, grilled, sauteed, or in a salad, but my favorite version is squash casserole. While this casserole does have a tasty creamy sauce, it’s a lot lighter than other Squash Casserole recipes since I use about half as much butter. To really put it over the top, I layer the squash around the skillet so more of the yummy sauce can drip between each tender slice.

I added a simple topping of buttery breadcrumbs and Parmesan cheese then let the cast iron skillet work it’s magic. Squash casserole is a classic southern dish for summer and at holiday gatherings. This simple dish has been a traditional family-favorite in my house for years and it’s destined to become a favorite in your recipe box too!

Ingredients Needed To Make This Easy Squash Casserole

Butter
Yellow Squash – sliced

Butter
Olive oil
Parmesan cheese

People Often Ask…

What Is Squash Casserole?

There are a million different answers to this question, depending on who you ask. Personally, I think that a southern squash casserole has to include fresh homegrown squash, a flavorful creamy sauce, and a cheesy crumb topping.
Many southerners like to use Cheddar Cheese in their squash casseroles. I prefer parmesan because I like the subtle flavor but you can absolutely use cheddar.

Do You Need To Peel The Squash Before Adding It To The Casserole?

One of the best aspects of this recipe is that it doesn’t require a ton of prep work. I personally do not peel my squash before adding it into the casserole, you can remove the skin if you’d like, but personally I think it just adds an extra step.

Can I Make Squash Casserole Without A Cast Iron Skillet?

Yes, you can absolutely make this recipe without a skillet! If you don’t have a cast iron at home, you can use any heavy-bottom metal pan, just make sure it doesn’t have any plastic on the handle. You can also use a 9×9 baking dish or a pie dish if that’s what you have available.

While I’ve never been a fan of casseroles, I do enjoy an occasional one. This looks great, so I’ll be asking my wife to try this recipe. It might just make it to the Thanksgiving feast at my niece’s house. Thanks!
