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
- Mayonnaise
- Milk
- Salt
- Pepper
- Garlic Powder
- Panko Breadcrumbs
- Butter
- Olive oil
- Parmesan cheese
People Often Ask…
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.
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.
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.
