This Cheesy Southern Squash Casserole is a warm and comforting dish packed with yellow squash and lots of melted cheese. It’s creamy, cheesy, and just plain yummy!
I love how it’s an easy way to sneak in some veggies while still enjoying the tasty cheesy goodness. Perfect as a side dish for dinner or a dish for family gatherings!
Key Ingredients & Substitutions
Yellow Squash: This is the star of the dish! Yellow squash brings a soft texture. You can substitute zucchini if you prefer a different flavor or can’t find squash. Both work well in this casserole.
Cheddar Cheese: Sharp cheddar gives this dish a nice kick, but you can use mild cheddar or even a blend of cheeses for a milder taste. If you’re looking for a dairy-free option, try vegan cheese that melts well.
Mayonnaise: This makes the casserole creamy. For a lighter version, substitute Greek yogurt or sour cream. You might also use a vegan mayo if you’re avoiding eggs and dairy.
Buttery Crackers: Ritz crackers add a nice crunch. Any similar buttery cracker will work, or you could use panko breadcrumbs for a different texture. Gluten-free options are available too!
How Do I Cook the Squash Just Right?
Cooking the squash properly is essential for your casserole’s texture. Use these tips:
- Slice the squash thinly so it cooks evenly.
- Cook in a skillet at medium heat just until tender, about 5-7 minutes. You want it soft, but not mushy!
- Drain any excess liquid after cooking to avoid a watery casserole.
Taking care with the squash will help ensure your casserole is perfect and not overly runny. Enjoy your cooking!

How Much Time Will You Need?
This Cheesy Southern Squash Casserole takes about 15 minutes of prep time and 30-35 minutes of baking time, making the total around 50 minutes. It’s quick to put together and perfect for gatherings or a cozy family dinner!
Step-by-Step Instructions:
1. Preheat Your Oven:
Start by preheating your oven to 350°F (175°C). Make sure to lightly grease a 9-inch baking dish or a cast iron skillet to prevent sticking.
2. Cook the Squash and Onion:
In a large skillet, add the sliced yellow squash and diced onion. Cook them over medium heat for about 5-7 minutes, until the squash is tender but still holds its shape. If there is any excess liquid, make sure to drain it to avoid a watery casserole.
3. Mix the Casserole Ingredients:
In a large mixing bowl, combine the cooked squash and onion with the shredded cheddar cheese, mayonnaise, and beaten eggs. Stir everything together until it’s well mixed. Then, add salt, pepper, and any optional seasonings you wish to use.
4. Prepare the Topping:
In a small bowl, mix the crushed buttery crackers with the melted butter. Stir until the crumbs are moistened. This will become the crunchy topping for your casserole!
5. Assemble the Casserole:
Pour the squishy, cheesy mixture into your prepared baking dish or skillet and spread it out evenly. Then, sprinkle the buttery cracker crumbs evenly over the top.
6. Bake the Casserole:
Place the casserole in the preheated oven and bake uncovered for 30-35 minutes. You’ll know it’s done when it’s bubbly and the top is golden brown.
7. Let It Cool:
Once it’s out of the oven, allow the casserole to cool for a few minutes before serving. This will help it set a bit more and make it easier to serve.
Enjoy the creamy, cheesy goodness of this delightful Southern side dish! It’s fantastic with fried chicken, BBQ, or just on its own.
Can I Use Different Types of Squash?
Yes! While yellow squash is traditional, you can substitute zucchini or a mix of summer squashes for a different flavor and texture. Just be sure to slice them thinly and adjust cooking time if necessary.
Can I Make This Casserole Ahead of Time?
Absolutely! You can prepare the casserole a day in advance. Just assemble it in the baking dish, cover it with plastic wrap, and refrigerate. When you’re ready to bake, simply remove the cover and bake as instructed, adding a few extra minutes if it’s coming straight from the fridge.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3-4 days. Reheat in the oven at 350°F until warmed through, or use the microwave for quick reheating.
What Can I Serve with Cheesy Southern Squash Casserole?
This casserole pairs wonderfully with fried chicken, BBQ ribs, or roasted meats. For a lighter meal, serve it alongside a fresh salad or some steamed vegetables!
