Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash is the star of this dish. If you don’t have any, zucchini works well as a substitute. Just make sure to slice thinly for even cooking.
Cheddar Cheese: I usually use sharp cheddar for extra flavor, but mild cheddar is perfect if you prefer a milder taste. You can also mix in other kinds like Monterey Jack or pepper jack for a kick!
Sour Cream: If you’re looking to lighten it up, Greek yogurt is a great substitution for sour cream. It delivers a similar tang and creaminess.
Mayonnaise: This ingredient adds richness. If you’re not a fan, you can skip it or use an extra dollop of sour cream or Greek yogurt instead.
Crushed Crackers: Ritz crackers are a classic topping, but you could use Panko breadcrumbs or croutons for added crunch if you prefer. Just adjust the butter amount accordingly for flavor.
How Do I Make Sure My Casserole Is Creamy and Not Watery?
Getting the right texture is key! Start by salting the squash and onions to draw out moisture. After draining, press the mixture gently to remove excess liquid. This will help keep your casserole creamy instead of watery.
- Slice squash and onion; sprinkle with salt and let drain in a colander for 10 minutes.
- Press lightly to squeeze out more liquid before mixing with other ingredients.
- Avoid overbaking the casserole to keep it creamy. Just bake until golden and bubbly (40-45 minutes).
These steps ensure a delightful texture that everyone will love! Enjoy the dish on its own or as a tasty side!

Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). While it heats up, grease a 9×9-inch baking dish or any similar casserole dish to prevent sticking.
2. Prepare the Vegetables:
Next, wash and thinly slice the yellow squash. Place the sliced squash and chopped onion in a colander and sprinkle them with a pinch of salt. Let them drain for about 10 minutes to remove excess moisture. After that, gently press the mixture to squeeze out even more liquid.
3. Mix the Main Ingredients:
In a large mixing bowl, combine your drained squash and onion with the sour cream, beaten eggs, mayonnaise, flour, salt, pepper, and garlic powder (if you’re using it). Mix everything until fully combined—get in there and don’t be shy!
4. Add the Cheese:
Now it’s time to stir in the shredded cheddar cheese. This will make your dish extra creamy and cheesy.
5. Assemble the Casserole:
Pour the mixture into your prepared casserole dish and smooth the top so it’s even. No need for perfection here; just try to make it look nice!
6. Prepare the Topping:
In a separate small bowl, mix the crushed cracker crumbs with the melted butter until the crumbs are evenly coated. Sprinkle this buttery mixture over the top of your casserole.
7. Bake It:
Place the casserole in the preheated oven and let it bake for 40 to 45 minutes. Keep an eye on it until it looks bubbly and golden brown; that’s when it’s ready!
8. Let It Rest:
When you remove the casserole from the oven, let it sit for about 5 minutes before serving. This allows it to set a bit and makes it easier to scoop. Enjoy your delicious and creamy Southern squash casserole!
