Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash is the star of this dish! If you can’t find it, zucchini is a great substitute. It brings a similar texture and mild flavor.
Onion: I prefer using a small yellow onion for its sweetness. You can swap it with a shallot or omit if you’re not a fan of onions.
Cheddar Cheese: Sharp cheddar adds a nice tangy flavor. You can use mild or even mozzarella for a different taste. Vegan cheese also works well if you’re avoiding dairy.
Mayonnaise & Sour Cream: These create a creamy texture. You could substitute them with Greek yogurt or a dairy-free yogurt for a lighter option.
Crackers: Buttery crackers add a nice crunch. If you’re gluten-free, use gluten-free crackers or breadcrumbs instead!
How Do I Make Sure the Squash Is Not Watery?
One of the challenges with squash casseroles is excess moisture. Here’s how to tackle it:
- Boil the squash and onion only until tender, about 5 minutes. Don’t overcook, or it will become mushy.
- After boiling, drain the squash thoroughly and give it a gentle squeeze to remove any extra moisture.
- Mix the squash with other ingredients only after ensuring it’s cooled slightly to avoid excess steam.
These steps will help you achieve a perfectly creamy casserole without the sogginess!

How Much Time Will You Need?
This Easy Yellow Squash Casserole takes about 10 minutes to prep, plus around 30-35 minutes of baking time. In total, you’re looking at about 45-50 minutes from start to finish, making it a quick and delicious addition to your meal!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 350°F (175°C). While it’s heating up, take a 9×9-inch baking dish and lightly grease it with cooking spray or a bit of butter. This will help prevent sticking.
2. Boil the Squash and Onions:
In a large pot, bring some water to a boil. Once boiling, add the sliced yellow squash and chopped onion. Let them cook for about 5 minutes until they’re tender. After that, drain the mixture well to remove excess water, and give it a gentle squeeze to get rid of any extra moisture.
3. Mix It All Together:
In a large bowl, combine the drained squash and onions with the shredded cheddar cheese, sour cream, mayonnaise, and the beaten egg. Mix everything until well combined. Don’t forget to season with salt and pepper to taste for extra flavor!
4. Assemble the Casserole:
Pour the squash mixture into your prepared baking dish and spread it out evenly with a spatula. This will create a nice, even layer for baking.
5. Prepare the Topping:
In a separate small bowl, combine the crushed buttery crackers or breadcrumbs with the melted butter, mixing well. Sprinkle this mixture evenly over the top of the squash mixture to create a crunchy topping.
6. Bake to Perfection:
Now it’s time to bake! Place the casserole in the preheated oven and let it bake for about 30-35 minutes. You’ll know it’s ready when it’s bubbly and the topping is wonderfully golden brown.
7. Cool and Serve:
Once baked, remove the casserole from the oven and let it cool for a few minutes before serving. This delicious Easy Yellow Squash Casserole is now ready to be enjoyed! Serve it warm as a side dish and watch it disappear!
