Key Ingredients & Substitutions
Yellow Squash: Fresh, slim yellow squash gives a mild taste. If yellow squash is unavailable, zucchini is a great substitute! Both have a similar texture and flavor.
Onion: A medium onion adds sweetness. You can use shallots or even green onions if you prefer a milder taste.
Cheddar Cheese: Sharp cheddar brings nice flavor. Feel free to swap it with Monterey Jack or even a dairy-free cheese for a lactose-free option.
Buttery Crackers: I love using Ritz for a crunchy topping. If you’re avoiding gluten, use gluten-free crackers or breadcrumbs instead!
Mayonnaise: This adds creaminess; Greek yogurt is an excellent alternative for a lighter touch.
What’s the Best Way to Prepare Yellow Squash for This Casserole?
The key to preparing yellow squash well is to ensure it isn’t too watery, which can make your casserole soggy. Here’s my tip:
- After boiling, drain the squash and onion thoroughly. Pat them dry with a paper towel to remove excess moisture.
- Slice the squash thinly and evenly for even cooking. This also allows for better mixing with other ingredients.
Following these simple steps will help achieve the right texture for a delicious casserole!

This Easy Yellow Squash Casserole takes about 15 minutes of prep time and 30-35 minutes of baking. So, in about 50 minutes, you’ll have a warm and delicious casserole ready for the table!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This will ensure it’s hot and ready when you pop in your casserole. Lightly grease a 9×13 inch casserole dish—this will help prevent sticking.
2. Prepare the Squash and Onion:
In a large pot, bring water to a boil. Add in the thinly sliced yellow squash and chopped onion. Cook for about 5 minutes until they’re tender but still firm. Drain well and pat dry with a paper towel to remove any extra moisture.
3. Mix the Casserole Ingredients:
In a big mixing bowl, combine the drained squash and onion with the eggs, mayonnaise, milk, salt, pepper, and garlic powder if you’re using it. Stir everything together until it’s well mixed and combined.
4. Add the Cheddar Cheese:
Now, fold in the shredded cheddar cheese gently without over-mixing. You want to keep that cheesy goodness spread throughout!
5. Assemble the Casserole:
Pour the squash mixture into your greased casserole dish and spread it out evenly. This helps ensure even cooking.
6. Prepare the Topping:
In a small bowl, combine the melted butter with the crushed crackers. Mix them well, then sprinkle this delicious buttery topping evenly over the top of the casserole.
7. Bake!
Place your casserole in the preheated oven. Bake for 30-35 minutes, or until the topping is golden brown and the casserole is bubbly around the edges.
8. Serve and Enjoy:
Once baked, take it out of the oven and allow it to cool for a few minutes. This will help it set a little. Serve warm and enjoy your scrumptious Easy Yellow Squash Casserole!
