This creamy Southern squash casserole is a warm hug in a dish! With tender squash and a rich cheese blend, it’s perfect for family gatherings or cozy dinners at home.
I love how easy it is to whip up! Just mix, bake, and enjoy! It’s always a hit—even my kids beg for seconds. Who knew veggies could be so tasty? 🥰
Key Ingredients & Substitutions
Yellow Squash: This is the star of the show! It gives the dish its signature flavor and texture. If you can’t find yellow squash, you can substitute with zucchini. Both work well when sliced thin.
Cheese: I like using sharp cheddar for its strong flavor, while mozzarella adds creaminess. Feel free to use any cheese blends you love; pepper jack can add a nice kick!
Sour Cream & Mayonnaise: These ingredients create a creamy base. Greek yogurt can be a great low-fat substitute for either, adding a nice tang.
Crackers: I typically use buttery crackers for that delicious crunch. Alternatively, breadcrumbs or even crushed cornflakes work just as well for the topping!
How Do I Ensure My Squash Is Perfectly Cooked?
Cooking the squash properly is essential for the best texture. You want it tender but not mushy. Here’s how to achieve that:
- Sauté the onions in butter first—this step builds flavor.
- After adding the sliced squash, keep the heat on medium and stir occasionally for even cooking.
- Check for doneness with a fork; it should be fork-tender in about 6-8 minutes.
- Don’t skip draining excess moisture to prevent a soggy casserole!
By following these tips, your creamy Southern squash casserole will be a guaranteed hit at the table! Enjoy cooking!

How Much Time Will You Need?
This creamy Southern squash casserole takes about 15 minutes to prepare and 30-35 minutes to bake, making a total time of around 50 minutes. Plus, you’ll want to let it rest for about 5 minutes before digging in. Perfect for a hearty side dish or a cozy main course!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). Grab a 9×13-inch baking dish and grease it lightly to prevent sticking.
2. Sauté the Onions:
In a large skillet, melt the butter over medium heat. Add the chopped onion to the skillet and sauté until it becomes translucent, usually taking about 5 minutes. This step enhances the flavor of your casserole!
3. Cook the Squash:
Next, add the sliced squash to the skillet. Cook it until it’s tender but not mushy, around 6-8 minutes. Make sure to drain any excess moisture from the squash to keep your casserole from getting soggy.
4. Mix the Ingredients:
In a large mixing bowl, combine the cooked squash and onions with the shredded cheddar and mozzarella cheeses, sour cream, mayonnaise, beaten eggs, sugar, salt, pepper, and garlic powder if you’re using it. Stir everything well until it’s creamy and combined.
5. Assemble the Casserole:
Pour the squash mixture into the prepared baking dish, spreading it out evenly so every bite gets that cheesy goodness.
6. Prepare the Topping:
In a small bowl, mix the crushed crackers (or breadcrumbs) with the grated Parmesan cheese. Sprinkle this mixture over the top of the casserole. This will create a yummy, crispy topping while it bakes.
7. Bake:
Place the dish in your preheated oven and bake for about 30-35 minutes. You’ll know it’s done when the top is golden brown and the casserole is bubbly around the edges.
8. Serve and Enjoy:
Once it’s finished baking, let the casserole rest for about 5 minutes. This will help it set a bit! Serve it warm and enjoy a delightful, comforting dish that’s sure to please everyone at the table!
This Southern squash casserole is a delightful mix of tender squash, rich cheeses, and a crispy topping—making it a fantastic addition to any meal or gathering.
Frequently Asked Questions (FAQ)
Can I Use Frozen Squash Instead of Fresh?
Yes, you can! Just make sure to thaw the frozen squash completely and drain any excess moisture before incorporating it into the recipe. Fresh squash will provide a better texture, but frozen is a convenient alternative when fresh isn’t available.
What Can I Substitute for Mayonnaise?
If you’re looking to lighten the dish, Greek yogurt is a great substitute for mayonnaise. It adds creaminess with less fat and a nice tang. You can also use additional sour cream in place of mayonnaise for a similar effect.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it in the oven at 350°F (175°C) until heated through. You can also microwave individual portions for convenience!
Can I Make This Casserole Ahead of Time?
Absolutely! You can prepare the casserole a day in advance and store it in the refrigerator before baking. Just cover it well with foil. When you’re ready to bake, you may need to add an extra 5-10 minutes to the cooking time as it will be cold from the fridge.
