This Southern Squash Casserole is a comforting dish full of fresh squash, cheese, and a crunchy topping. It’s creamy, cheesy, and so satisfying—perfect for family gatherings!
To be honest, this casserole is my go-to when I need to impress without the stress. Plus, you get to sneak in extra veggies! Who knew eating healthy could taste this good? 😄
Key Ingredients & Substitutions
Yellow Squash: This is the star of the dish! While yellow squash is the classic choice and gives that perfect texture, zucchini can work too. Just slice it thinly to ensure it cooks evenly.
Onion: A medium onion adds flavor, but if you prefer something milder, try using a shallot or green onions. They add a subtle sweetness and keep the dish light.
Cheddar Cheese: I love sharp cheddar for its bold taste. However, feel free to mix it up with mozzarella for a milder flavor or pepper jack if you like a bit of spice!
Sour Cream: This ingredient makes the casserole creamy. Greek yogurt is a great substitute if you’re looking for a healthier option—I often use it for added protein!
Buttery Crackers: Ritz are classic, but crushed panko bread crumbs can also create a nice crunch without the buttery taste. You can sprinkle them with a bit of melted butter for flavor!
How Can You Ensure Your Squash Casserole Is Perfectly Creamy?
Getting the creamy texture just right is crucial for this casserole. Here’s how to do it:
- Start by sautéing the squash and onion slowly. This helps to draw out excess moisture, so your casserole isn’t watery.
- Mix the cheese and sour cream thoroughly with the squash and onion mixture. It should be creamy without lumps.
- Don’t skip draining the veggies after sautéing—they need to be tender but not sitting in liquid.
With these steps, you’ll have a creamy casserole every time! Trust me, it’s worth the extra effort for that delicious texture.

- 1 cup crushed buttery crackers (such as Ritz)

Time Estimate:
This recipe takes about 15 minutes for preparation and an additional 30-35 minutes to bake. In total, you should plan for around 50 minutes to enjoy this delicious Southern dish from start to finish!
Detailed Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 350°F (175°C). Grab a 9×13-inch baking dish and lightly grease it with some cooking spray or a bit of oil to prevent sticking. This will keep the casserole nice and easy to serve!
2. Sauté the Vegetables:
In a large skillet, add the sliced yellow squash and chopped onion. Cook them over medium heat for about 8-10 minutes or until they become tender. This step helps to release any extra moisture, keeping your casserole from being too watery. Once cooked, drain any excess liquid before moving on!
3. Combine Ingredients:
In a large mixing bowl, combine the cooked squash and onion with the shredded cheddar cheese, sour cream, beaten eggs, salt, black pepper, and garlic powder (if you’re using it). Mix everything together until it’s well combined and creamy.
4. Transfer to Baking Dish:
Pour the mixture into the greased baking dish and spread it out evenly. This ensures every bite has that delicious flavor!
5. Prepare the Topping:
In a small bowl, stir together the crushed buttery crackers and half of the melted butter until the crumbs are evenly coated. This mixture will give your casserole a nice crunchy top!
6. Assemble and Drizzle:
Evenly sprinkle the cracker mixture over the top of your squash mixture in the baking dish. Then, drizzle the remaining melted butter over the cracker topping—it helps achieve that lovely golden brown color.
7. Bake to Perfection:
Place the casserole in the preheated oven and bake uncovered for 30-35 minutes. You’re looking for the casserole to bubble and the topping to turn a beautiful golden brown.
8. Cool and Serve:
Once done, remove the casserole from the oven and allow it to cool for a few minutes. This makes it easier to serve. Enjoy your creamy, cheesy, and crunchy Southern squash casserole with family and friends!
