Key Ingredients & Substitutions
Yellow Squash: Fresh, yellow squash is key for this dish. You can also use zucchini if that’s what you have on hand. Both varieties bring a nice, tender texture.
Onion: Yellow or white onions work best for flavor. If you want a milder taste, go for green onions or shallots. They add a subtle sweetness without overpowering!
Cheddar Cheese: Sharp cheddar gives a great flavor, but feel free to mix it up! Monterey Jack or Colby cheese can also work, and for a twist, try adding some Pepper Jack for a bit of heat.
Mayonnaise & Sour Cream: These both make the casserole creamy. If you need a lighter version, you can substitute Greek yogurt for a tangy twist! Some might prefer using ranch dressing for an extra flavor boost.
Crushed Crackers: Buttery crackers add a nice crunch. If you want a gluten-free option, use crushed gluten-free crackers or panko breadcrumbs.
How Do I Make Sure My Squash Casserole is Creamy and Not Runny?
The moisture from the squash can make a casserole watery. To avoid this, it’s important to drain cooked squash well. After boiling, let it cool in a colander to remove excess moisture.
- When combining ingredients, make sure you mix them until creamy, helping to distribute moisture evenly.
- It’s also helpful to let the casserole sit for a few minutes after baking. This lets it set and makes serving easier!

This Southern squash casserole takes about 15 minutes to prepare and 35-40 minutes to bake, so you’re looking at about 60 minutes total before you can dive in. It’s a quick and easy dish perfect for any gathering!
Step-by-Step Instructions:
1. Prepare the Oven and Dish:
Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray to make sure the casserole doesn’t stick.
2. Cook the Squash:
In a large pot, bring water to a boil. Add in your sliced yellow squash and cook for 3-4 minutes until they become just tender. Drain the squash and allow it to cool slightly. This step helps to get rid of excess moisture!
3. Mix the Ingredients:
In a big mixing bowl, combine the cooked squash, chopped onion, 1 1/2 cups of shredded cheddar cheese, eggs, mayonnaise, sour cream, flour, salt, black pepper, and any optional garlic powder or paprika. Mix everything together until it’s well combined and creamy.
4. Assemble the Casserole:
Pour the creamy squash mixture into the prepared baking dish, spreading it evenly to ensure it cooks properly.
5. Prepare the Topping:
In a small bowl, mix the crushed crackers with the melted butter. This will create a delicious crunchy topping! Sprinkle this evenly over the squash mixture in the baking dish.
6. Add More Cheese:
Top the casserole with the remaining 1/2 cup of shredded cheddar cheese for that beautiful, gooey finish that everyone loves.
7. Bake to Perfection:
Place the dish in the preheated oven and bake for 35-40 minutes, or until the casserole is bubbly and the topping is golden brown. Your kitchen will smell amazing!
8. Let it Rest:
Once it’s done baking, take the casserole out of the oven and let it sit for about 5 minutes. This helps it set and makes it easier to serve. Now you’re ready to enjoy your creamy, cheesy Southern delight!
This casserole goes wonderfully with roasted meats or a fresh salad as a comforting side dish that will be a hit at any meal. Enjoy!
Can I Use Frozen Squash for This Recipe?
While fresh squash is preferred for the best texture, you can use frozen squash if necessary. Just make sure to thaw and thoroughly drain it before using to prevent excess moisture in the casserole.
Can I Make This Casserole Ahead of Time?
Absolutely! You can prepare the casserole up to a day in advance. Simply follow the recipe, cover it tightly, and refrigerate before baking. When ready to bake, you may need to add a few extra minutes to the cooking time if it’s coming from the fridge.
How Should I Store Leftovers?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, it’s best to warm it gently in the oven for crispy topping or in the microwave if you’re in a hurry!
Can I Customize the Cheese in This Recipe?
Definitely! While cheddar cheese is traditional, feel free to mix in different cheeses like Monterey Jack, Pepper Jack for a bit of spice, or even cream cheese for extra creaminess. Just be sure to maintain the total amount of cheese used to keep the texture right.
