Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash is key for flavor and texture. If you can’t find it, zucchini works well as a substitute. It’ll give a similar look and taste.
Cheddar Cheese: I love using sharp cheddar for that rich flavor. If you prefer a milder cheese, try mozzarella or Monterey Jack instead. You could even use a dairy-free cheese if you’re avoiding dairy.
Sour Cream: This adds creaminess. Greek yogurt can be a good substitute for a tangy taste, and it’s lower in fat. Coconut yogurt is also an option for a dairy-free version.
Ritz Crackers: Crushed Ritz give a delicious crunchy topping. If you don’t have them, any buttery crackers or even panko breadcrumbs can work. Panko will give a lighter crunch!
How Do I Cook Yellow Squash so it’s Tender and Delicious?
Cooking yellow squash properly is essential for a tasty casserole. You want it tender without turning mushy. Here’s how:
- Start by slicing the yellow squash thinly; about 1/4 inch is ideal.
- In your skillet, melt butter and add the squash and onions. Cooking them on medium heat for 8-10 minutes softens them.
- Keep stirring occasionally to ensure even cooking. If you notice they start browning, it’s a sign you should lower the heat a bit.
Letting them cool slightly before mixing with other ingredients is key too, as it helps the casserole set nicely.

Step-by-Step Instructions:
1. Preheat and Prepare the Dish:
Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to prevent sticking—this will help with easy serving later!

Cook while stirring occasionally until the squash is tender—this should take about 8-10 minutes. Once done, remove it from the heat and let it cool slightly. This step helps maintain the flavor and texture of the squash.

In a large mixing bowl, combine the cooled squash mixture with shredded cheddar cheese, sour cream, beaten eggs, salt, and black pepper. Stir everything together until it’s well-mixed and creamy. This is the heart of your casserole!
4. Assemble the Casserole:
Pour the squash mixture evenly into the prepared baking dish. Spread it out with a spatula to create an even layer—this helps all parts cook uniformly.
5. Create the Topping:
In a small bowl, combine the crushed Ritz crackers, grated Parmesan cheese (if you’re using it), and melted butter. This will create a crunchy, buttery topping that adds great texture. Sprinkle this mixture evenly over the casserole, covering the filling nicely.
6. Bake the Casserole:
Place the casserole in the preheated oven and bake for 30-35 minutes. You’ll know it’s ready when the casserole is set and the topping is golden brown. Your kitchen will smell fantastic!
7. Serve and Enjoy:
