Key Ingredients & Substitutions
Yellow Squash: This is the star of the dish! If you’re in a bind, zucchini can be a nice alternative. It has a similar texture and flavor.
Onion: Using onion adds depth to the flavor. If you’re not a fan, try using shallots or even garlic for a more subtle taste.
Cheddar Cheese: Sharp cheddar gives a beautiful flavor. If you want something milder, go for mild cheddar or even mozzarella. There’s also a lovely option of using pepper jack for a kick!
Parmesan Cheese: This adds a touch of savory richness. If you don’t have it, nutritional yeast can work as a dairy-free alternative, or simply bump up the cheddar.
Sour Cream & Mayonnaise: These add creaminess. Plain Greek yogurt can replace both for a slightly healthier option, while keeping that creamy texture.
How Do I Get My Squash Just Right?
Blanching squash is key for this recipe. It softens the squash just enough without letting it get mushy. Here’s how to do it right:
- Boil water and add sliced squash and onions.
- Let them cook for about 3-4 minutes until tender but still firm.
- Drain the veggies well, and aim to cool them quickly to stop the cooking process. You might even run them under cold water if needed!
This method helps enhance the flavors while keeping the perfect texture in your casserole!

Step-by-Step Instructions:
1. Preheat Your Oven:
Start by preheating your oven to 350°F (175°C). While it heats up, grease a 9×13-inch baking dish to prevent sticking and set it aside for later.
2. Blanch the Squash and Onions:
In a large pot, bring water to a boil. Add the sliced yellow squash and chopped onions, gently boiling them for about 3-4 minutes until they are just tender. Be sure to drain them well and set aside to cool slightly—this helps keep the casserole from being watery!
3. Mix the Base:
In a large mixing bowl, whisk together the beaten eggs, sour cream, mayonnaise, garlic powder, salt, and black pepper. Stir until everything is smooth and well combined—this will be the creamy base of your casserole!
4. Combine with Squash:
Add your blanched squash and onions into the egg mixture, and gently fold in the shredded cheddar and grated Parmesan cheeses until evenly incorporated.
5. Assemble the Casserole:
Pour the mixture into your prepared baking dish, spreading it out evenly. This will form the hearty, cheesy filling that you’ll love!
6. Prepare the Topping:
In a small bowl, combine the buttery cracker crumbs with melted butter. Mix them together well and then sprinkle this crunchy topping evenly over the casserole for a delightful finish.
7. Bake:
Pop the casserole into the preheated oven and bake for 35-40 minutes. You’re looking for the casserole to be set and the topping to be golden brown—delicious aroma will fill your kitchen!
8. Cool and Serve:
Once baked, let your casserole cool for about 5-10 minutes before serving. This allows it to set perfectly. Enjoy this cozy, cheesy Southern classic with family and friends!
Cozy Southern Cheese Squash Casserole FAQ
Can I Use Frozen Squash for This Recipe?
Yes, you can use frozen squash, but be sure to thaw and drain it completely before using it in the casserole. This prevents extra moisture that could make your dish watery!

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until warmed through. You might want to add a splash of cream or broth before reheating to keep it creamy!
Can I Make This Casserole Ahead of Time?
Absolutely! You can assemble the casserole in advance, cover it tightly, and refrigerate for up to 24 hours before baking. When ready to bake, it might need an extra 5-10 minutes in the oven if starting from the fridge.
What Can I Substitute for the Mayonnaise?
