Key Ingredients & Substitutions
Zucchini & Yellow Squash: These are the stars of the casserole! If you can’t find them, feel free to use other summer squash variations. Even eggplant could work well if you’re feeling adventurous!
Cheddar and Mozzarella: These cheeses add flavor and creaminess. If you want a sharper taste, try using sharp cheddar. For a lower-fat option, reduced-fat cheese can do the trick, but it may not melt as beautifully.
Sour Cream & Mayonnaise: These ingredients give the casserole a creamy texture. You can swap sour cream with Greek yogurt for a healthier option. If mayo isn’t your thing, skip it and use more sour cream or yogurt!
Breadcrumbs: They help create a nice crunchy layer on top. If you’re looking for a gluten-free option, use crushed gluten-free crackers or skip the topping altogether.
How Do I Prevent My Casserole from Being Watery?
A common issue with zucchini is excess moisture. Here’s how to avoid that: after slicing the zucchini and yellow squash, sprinkle them with salt and let them sit for about 10 minutes. This draws out moisture. Afterward, be sure to drain any liquid before mixing with the other ingredients.
- Slice and salt the zucchinis and squash.
- Let them rest to release moisture.
- Drain well to keep the casserole from becoming soupy.
By following these steps, your casserole will turn out creamy but not watery! Enjoy your cooking! 🥒

How Much Time Will You Need?
This Easy Cheesy Zucchini Squash Casserole takes about 15 minutes of prep time, plus an additional 30-40 minutes of baking time. In total, you’ll be looking at around 55 minutes from start to finish. A delicious side dish is just around the corner!
Step-by-Step Instructions:
1. Prepare the Oven and Dish:
Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to prevent sticking. This will ensure your casserole comes out perfectly from the dish later on.
2. Prepare the Zucchini and Squash:
In a large bowl, mix the sliced zucchini and yellow squash. Lightly sprinkle them with salt and let them sit for about 10 minutes. This step helps draw out excess moisture from the veggies. After 10 minutes, drain any liquid, so your casserole won’t be watery later.
3. Mix the Creamy Ingredients:
While the squash is resting, take a separate bowl and combine the sour cream, mayonnaise, garlic powder, onion powder, dried basil, salt, and pepper. Mix this well until everything is combined into a smooth and creamy mixture.
4. Combine Everything:
Now, add the drained zucchini and yellow squash to the creamy mixture and stir well until they are thoroughly coated. This step is crucial for ensuring every bite is full of flavor!
5. Add the Cheeses:
Fold in the shredded cheddar and mozzarella cheese. Make sure to reserve a small amount of cheese for topping later. Gently combine everything to ensure it’s well distributed.
6. Transfer to the Baking Dish:
Pour the mixed ingredients into your prepared baking dish and spread it evenly. This mixture will soon become a cheesy, golden delight in the oven.
7. Add the Toppings:
Sprinkle the grated Parmesan cheese and the reserved shredded cheese over the top. If you’re using breadcrumbs or crushed crackers, mix them with melted butter and sprinkle that on as well for a delicious crispy topping.
8. Bake to Perfection:
Place the casserole in the preheated oven and bake for 30-40 minutes, or until it’s bubbly and golden brown on top. The kitchen will smell amazing during this time!
9. Cool and Serve:
Once baked, let the casserole cool for a few minutes before serving to allow it to set slightly. This dish is best served warm, and I’m sure everyone will enjoy the cheesy goodness!
Now, dig in and enjoy your Easy Cheesy Zucchini Squash Casserole! It’s delightful as a side dish or even as a main vegetarian meal! 🥒🧀
