Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash is key for this dish. If you can’t find it, zucchini makes a great substitute for taste and texture.
Onion: Adding chopped onion adds flavor. Skip it if you’re not a fan or use green onions for a milder taste.
Cheddar Cheese: Sharp Cheddar brings a bold flavor. For a milder version, use Monterey Jack or Mozzarella. Blend cheeses for a unique taste!
Sour Cream: This adds creaminess. Greek yogurt can work as a healthy swap, giving you that same richness.
Cracker Crumbs: Buttery crackers give a nice crunch. Use crushed cornflakes or panko crumbs if you need gluten-free options.
What’s the Best Way to Prepare the Squash?
Preparing the squash correctly is essential for a tasty casserole. Start by slicing the squash thinly to ensure it cooks evenly. The salt helps to draw out moisture, so letting it sit for 10 minutes makes a big difference in texture.
- After resting, drain the squash well. You can use a colander for this step, and make sure to squeeze out any extra moisture with a paper towel.
- This prevents the casserole from becoming watery while baking!

Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This will ensure that your casserole cooks evenly. Also, grease your 2-quart casserole dish with a little butter or non-stick spray to avoid sticking.
2. Prepare the Squash:
In a large bowl, combine the sliced yellow squash and optional chopped onion. Sprinkle with salt and let it sit for about 10 minutes. This helps draw out some moisture from the squash. Afterward, drain any excess liquid and gently pat the squash dry with paper towels.
3. Mix the Cheese Filling:
In another bowl, mix together the shredded Cheddar cheese, sour cream, beaten eggs, all-purpose flour, melted butter, black pepper, and optional garlic powder. Stir well until everything is creamy and combined.
4. Combine Squash and Cheese Mixture:
Add the drained squash and onion mixture into the cheese mixture. Stir it all together gently until everything is coated nicely with the cheesy goodness.
5. Assemble the Casserole:
Pour the combined mixture into your greased casserole dish, spreading it evenly to ensure it cooks uniformly.
6. Add Topping:
Now, sprinkle the crushed buttery cracker crumbs over the top of the casserole. This will add a delightful crunch when baked!
7. Bake to Perfection:
Place the casserole in the preheated oven and bake for 35-45 minutes. You’ll know it’s ready when the casserole is bubbling and the topping is golden brown.
8. Cool and Serve:
Once baked, remove the casserole from the oven and let it cool for a few minutes. This will make serving easier. Enjoy your cheesy Southern squash casserole as a comforting side to your favorite meals!
