This creamy yellow squash casserole is the perfect side dish for any meal! Made with fresh squash, cheese, and a crunchy topping, it’s a delightful combination of flavors and textures.
I love how easy this casserole is to whip up. Just mix everything together, bake, and enjoy! Honestly, it’s a great way to sneak in some veggies without anyone noticing. 😄
Key Ingredients & Substitutions
Yellow Squash: Fresh yellow squash brings great flavor and texture. If you can’t find it, zucchini can work as a substitute. It has a similar texture and cooking properties.
Cheddar Cheese: I love sharp cheddar for its bold flavor, but feel free to swap it for Monterey Jack or Colby for a milder taste. Vegan cheese is also a great option if you’re dairy-free!
Sour Cream & Mayonnaise: For a healthier choice, Greek yogurt can replace sour cream and mayonnaise. It adds creaminess and a little tang while boosting protein. You can also use a dairy-free version.
Crackers: I use buttery crackers for crunch, but breadcrumbs or even crushed potato chips can work just as well. Gluten-free options are available if needed!
How Do I Get the Right Texture for My Casserole?
The texture of your casserole is essential for the best results. Follow these tips to ensure your dish comes out perfectly creamy and cohesive:
- Cooking the squash and onions for just 5 minutes softens them without making them mushy, allowing them to hold their shape.
- Mix the cheese, sour cream, and mayonnaise thoroughly to create a smooth base. This will help bind everything together.
- If you use eggs, they help the casserole stay together and give it a fluffy texture. Don’t skip this if you’re looking for a firmer consistency!
- Sprinkling the buttery crackers on top adds a delightful crunch that contrasts nicely with the creamy filling.

Start by preheating your oven to 350°F (175°C) to get it nice and hot while you prepare the casserole.

Transfer the squash mixture into a greased 9×13-inch baking dish. Spread it out evenly for the best baking results.

Place the baking dish in the preheated oven and bake for 30 to 35 minutes. You’re looking for a bubbly casserole with a golden-brown top—this means it’s ready to go!
