Key Ingredients & Substitutions
Yellow squash: This is the star ingredient! If you can’t find yellow squash, zucchini works well too. Both have a mild flavor that takes on seasoning beautifully.
Cheddar cheese: Sharp cheddar adds a nice flavor punch. You can use mild or medium cheddar for a subtler taste. If you prefer dairy-free, try a plant-based cheese alternative.
Sour cream: This adds creaminess and a slight tang. You can substitute Greek yogurt if you want a healthier option, or even use cottage cheese for a different texture.
Mayonnaise: It gives a rich creaminess to the casserole. You can use Greek yogurt or a vegan mayo for lighter or dairy-free options.
Crushed buttery crackers: These add a nice crunch on top. If you’re looking for a gluten-free option, crushed cornflakes or gluten-free crackers can be easily used.
How Do You Keep Your Casserole from Getting Watery?
One key to preventing a watery casserole is to properly drain and pat dry your cooked squash and onions. After boiling, let them sit in a colander for a bit to make sure excess water escapes. Drying them with paper towels helps a lot, too!
- Boil the squash and onion for just a few minutes to soften them, then drain well.
- Press them lightly with paper towels to soak up any remaining moisture.
- Mix in the other ingredients thoroughly to ensure a well-bound casserole.
With these simple tips, you’ll have a perfect, creamy casserole every time! Enjoy every bite of this cozy dish.

Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). While the oven is heating, lightly grease a 9×13-inch baking dish to prevent sticking.
2. Cook the Squash and Onions:
In a large pot, bring water to a boil. Add the sliced yellow squash and chopped onion. Let them cook for about 5 minutes until they are tender but not mushy. Then, drain them well in a colander. Pat the squash and onions dry using paper towels to remove any excess moisture, ensuring a nice casserole consistency.
3. Mix the Casserole Filling:
In a large mixing bowl, combine the drained squash and onions with the beaten eggs, sour cream, mayonnaise, shredded cheddar cheese, and shredded mozzarella cheese if using. Add salt, pepper, garlic powder, and any herbs you choose. Stir everything together until well mixed and creamy.
4. Prepare for Baking:
Pour the mixture into your prepared baking dish and smooth the top with a spatula to ensure even cooking.
5. Add the Crunchy Topping:
In a small bowl, mix the crushed crackers with melted butter. Sprinkle this mixture evenly over the top of the casserole for a delightful crunch.
6. Bake:
Place the dish in the preheated oven and bake uncovered for 35-40 minutes, or until the casserole is bubbly and the topping is a light golden brown.
7. Let it Cool & Serve:
Once baked, let the casserole cool for about 10 minutes before serving. This comforting dish pairs wonderfully with roasted meats or can happily stand alone as a main dish. Enjoy every cheesy bite!
