This Southern Squash Casserole is a warm and cheesy dish that’s super comforting. Filled with fresh squash, onion, and rich cheese, it’s hard to resist!
Seriously, this casserole is like a hug on your plate. I love serving it with cornbread for a true Southern meal. Your family will be begging for seconds! 😄
Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash gives this dish its signature flavor. Zucchini can be used as a substitute if needed, or try a mix of both for a colorful twist!
Onion: I recommend using sweet onions for a milder taste. If you’re sensitive to onion flavor, green onions or shallots can work instead.
Cheddar Cheese: Sharp cheddar adds awesome flavor, but feel free to mix it up with Monterey Jack or even a blend of cheeses. Vegan cheese can be a good option if you’re avoiding dairy.
Sour Cream: Greek yogurt can be a lighter alternative to sour cream while still giving creaminess to the casserole.
Cracker Crumbs: If you don’t have crackers on hand, panko breadcrumbs or crushed cornflakes can create a similar crunchy topping!
How Do I Cook the Squash Without Making It Soggy?
It’s important to cook the squash just enough to soften it but not to mush. Here’s how to keep it perfect:
- Boil the squash and onion for only 5 minutes and immediately drain to remove moisture.
- Let the squash sit in a colander for a bit after draining to avoid excess water in your casserole.
- For an extra step, you can sauté them in a pan instead of boiling. This also helps release moisture!

How Much Time Will You Need?
This delicious casserole requires about 15 minutes for prep and then 30-35 minutes of baking time. So in total, expect to spend around 50 minutes before it’s ready to enjoy. Perfect for a weeknight dinner or gathering with friends!
Step-by-Step Instructions:
1. Preheat and Prepare Squash:
First, preheat your oven to 350°F (175°C). In a large pot, bring water to a boil. Carefully add the sliced squash and chopped onion, letting them cook for about 5 minutes—just enough to soften them. Drain the squash and onion well, then let them sit in a colander to get rid of any water. This helps keep your casserole from getting soggy!
2. Combine Ingredients:
In a large mixing bowl, mix the drained squash and onions with shredded cheddar cheese, sour cream, eggs, mayonnaise, salt, black pepper, and garlic powder if you want that extra flavor kick. Stir everything together until it’s well combined. You want a nice, creamy mixture that will hold together nicely in the casserole.
3. Prepare the Baking Dish:
Grab a 9×13-inch baking dish and lightly grease it with butter or cooking spray. This will help prevent sticking and make it easier to serve later.
4. Assemble the Casserole:
Pour the squash mixture into the prepared baking dish, using a spatula to spread it out evenly so that it bakes evenly. This will be the heart of your casserole!
5. Add the Crunchy Topping:
In a small bowl, take your crushed cracker crumbs and mix them with the melted butter until they are all moistened. Then, sprinkle this mixture evenly over the top of your casserole for a delicious crunchy finish.
6. Bake to Perfection:
Now it’s time to bake! Place the casserole in your preheated oven and let it cook for about 30-35 minutes. You’ll know it’s ready when the top turns golden brown and the casserole is set.
7. Cool and Serve:
Once it’s out of the oven, let it cool for a few minutes so it’s easier to serve. Slice and dish up your comforting and cheesy Southern squash casserole—it’s ready to be enjoyed!
Enjoy your delicious creation! This Southern classic is sure to be a hit at your table!
