Ingredients & Substitutions
Yellow Squash: This is the star of the dish! If you can’t find yellow squash, zucchini is a great stand-in. You could also mix both for more color and flavor.
Onion: Use a medium onion for sweetness. If you want a milder flavor, go for green onions or even shallots.
Cheddar Cheese: Sharp cheddar adds a lovely kick. If you prefer a milder taste, try mild cheddar or Monterey Jack. Vegan cheese can also work here for a dairy-free option.
Sour Cream & Mayonnaise: Greek yogurt is a fantastic substitute for both sour cream and mayo, adding creaminess with extra protein.
Buttery Crackers: Ritz crackers are classic, but if you need a gluten-free option, look for gluten-free cracker brands. Even breadcrumbs can substitute if you’re in a pinch!
How Do I Make Sure the Squash Isn’t Soggy?
Getting the perfect texture for your squash casserole is key. Here’s how to avoid sogginess:
- Start by slicing your yellow squash thin, about 1/4 inch. This helps it cook evenly.
- Blanch the squash and onion in boiling water for just 5 minutes to soften. Drain them well to remove excess moisture.
- Mix the squash when it’s relatively dry, and avoid excess liquid to get that creamy yet firm casserole consistency.

For the Casserole:
- 4 cups yellow squash, sliced
- 1 medium onion, finely chopped
- 1 cup shredded sharp cheddar cheese
- 1 cup sour cream
- 1/2 cup mayonnaise
- 1/4 cup grated Parmesan cheese
- 1 teaspoon garlic powder

How Much Time Will You Need?
This creamy yellow squash casserole will take you about 15 minutes to prep and 30 to 35 minutes to bake. Make sure to let it cool for a few minutes before you dive in. Total time is around 50 minutes! Perfect for a comforting side dish or a light main course.
Step-by-Step Instructions:
1. Preheat Your Oven:
Start by preheating your oven to 350°F (175°C). This ensures it’s hot and ready to give your casserole a nice, bubbly finish.
2. Cook the Squash and Onion:
In a large pot, bring water to a boil. Add in your sliced yellow squash and chopped onion. Let them cook for about 5 minutes until they’re just tender. Drain them well to avoid any excess water in your casserole.
3. Mix the Ingredients:
In a large mixing bowl, combine the drained squash and onions with the shredded cheddar cheese, sour cream, mayonnaise, Parmesan cheese, garlic powder, salt, pepper, and nutmeg (if you’re using it). Stir everything together until it’s well blended and creamy.
4. Get the Casserole Ready:
Spray or grease a 9×13 inch baking dish. Pour your mixture into the dish and spread it out evenly so it bakes nicely.
5. Prepare the Topping:
In a small bowl, mix the crushed buttery crackers with melted butter until the crumbs are well coated. This will give your casserole a delicious crunch!
6. Top and Bake:
Sprinkle the buttery cracker mixture over the top of the casserole evenly. Place the dish in your preheated oven and bake for 30 to 35 minutes, or until the top is golden brown and the casserole is bubbly.
7. Cool and Serve:
Once out of the oven, let the casserole cool for a few minutes before serving. This allows the flavors to meld and makes it easier to serve. Enjoy your creamy delight!
Can I Use Different Types of Squash?
Yes! While yellow squash is the star of this dish, zucchini can be a great substitute or you can mix both for variety. Just ensure that the squash is sliced thinly for even cooking.
Can I Make This Casserole Ahead of Time?
Absolutely! You can assemble the casserole up to a day in advance. Just cover it with plastic wrap and refrigerate. When you’re ready to bake, remove it from the fridge and allow it to sit at room temperature for about 20 minutes before putting it in the oven.
How Do I Store Leftovers?
Leftover casserole should be stored in an airtight container in the fridge and can last for up to 3 days. To reheat, place it in the oven at 350°F (175°C) for about 15-20 minutes until warmed through, or you can use the microwave for quicker reheating.
Can I Add Other Vegetables to the Casserole?
Definitely! Feel free to add other veggies like bell peppers, spinach, or even corn to enhance the flavor and nutrition. Just make sure to sauté any additional veggies first to reduce moisture before adding them to the casserole mix.
