This Southern squash casserole is like a warm hug on a plate! It’s creamy, cheesy, and packed with fresh squash. Perfect for using up all those summer veggies!
You can’t go wrong with all that gooey cheese on top. Whenever I make it, I can’t resist sneaking bites before it hits the table! 🤭 Serve it warm, and watch it disappear!
Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash gives this casserole its classic flavor. If you’re in a pinch, zucchini works great as a substitute!
Onion: A medium onion adds depth. If you’re not a fan, you can leave it out or use green onions for a milder taste.
Cheddar Cheese: Sharp cheddar is my top choice for that tangy kick, but feel free to mix in Monterey Jack or even a spicy pepper jack for a twist!
Sour Cream: This makes the casserole creamy. Greek yogurt is a healthy alternative that also brings a nice tang!
Crackers: I love using buttery crackers for the topping. If you’re gluten-free, crushed gluten-free crackers work just as well.
How Do You Ensure Your Squash is Not Watery?
One common struggle with squash casseroles is excess water. To avoid this, it’s essential to properly drain your cooked squash. After boiling, let it sit in a strainer for a bit and then pat with paper towels to soak up any remaining moisture.
- Boil the squash until tender, about 5 minutes, and drain thoroughly.
- Ensure it’s dried well before mixing it into the casserole. This will help keep the casserole nice and firm.
Taking these extra steps can really elevate your squash casserole, resulting in a dish that’s rich and creamy without any unwanted sogginess. Happy cooking!

Step-by-Step Instructions:
1. Prepare the Oven and Dish:
First, preheat your oven to 350°F (175°C). While it’s heating, grease a 9×13-inch baking dish to make sure your casserole doesn’t stick.
2. Cook the Squash:
Rinse the sliced yellow squash under cold water, then place it in a large pot with lightly salted water. Bring the water to a boil and cook the squash until it’s tender, about 5 minutes. Once done, drain the squash and set it aside. Let it dry, or pat it with paper towels to remove any extra moisture.
3. Mix the Casserole Ingredients:
In a large bowl, add the cooked squash and chopped onion. Then, mix in the shredded cheddar cheese, sour cream, and beaten eggs. Sprinkle in the salt, pepper, garlic powder, and onion powder if you’re using them. Stir everything together until it’s well blended.
4. Assemble the Casserole:
Pour the squash mixture into the greased baking dish and spread it out evenly.
5. Prepare the Topping:
In another bowl, combine the crushed crackers with melted butter, ensuring all the crumbs are coated. Sprinkle this mixture evenly over the squash layer. If you like, sprinkle some grated Parmesan cheese on top for extra flavor!
6. Bake:
Place the dish in the preheated oven and bake it uncovered for about 30 to 35 minutes, or until the casserole is bubbling and the top is golden brown.
7. Let It Rest:
Once it’s done, take it out of the oven and let the casserole sit for 5 minutes before serving. This allows it to set a little bit and makes it easier to serve.
Enjoy this comforting Southern classic alongside your favorite main dishes! It’s sure to become a family favorite!
