Zucchini and Squash Casserole Recipe
This Zucchini and Squash Casserole is a wonderfully simple yet incredibly flavorful way to enjoy the bounty of summer vegetables. It’s the kind of dish that’s perfect as a side for a weeknight dinner or elegant enough to grace your holiday table. The combination of tender zucchini and yellow squash, coated in a savory, cheesy, and slightly crunchy topping, makes it a guaranteed crowd-pleaser.

One of the best things about this casserole is how adaptable it is. While the recipe below is fantastic as is, feel free to experiment with adding other vegetables like finely diced bell peppers or onions if you have them on hand. You can also adjust the cheese to your liking – a sharp cheddar or a Monterey Jack would also be delicious additions. But for a classic, straightforward approach that lets the squash shine, this recipe is hard to beat. Let’s get cooking!
Ingredients:
- 2 pounds summer squash (zucchini and yellow squash, cut into ¼-inch slices)
- 2 ½ tablespoons olive oil
- 1 ¼ teaspoons salt (divided)
- ½ teaspoon pepper
- ⅓ cup grated Parmesan cheese (grated)
- ⅓ cup Panko breadcrumbs (gluten-free)
- ¼ teaspoon garlic powder
- 2 tablespoons fresh parsley (finely chopped)
Preparing the Squash
The first step in creating this delicious casserole is to prepare our star ingredients: the zucchini and yellow squash. We want to ensure they are tender and not watery, which can sometimes be a challenge with summer squash. To achieve this, we’ll be giving them a quick sauté. Start by washing your squash thoroughly. Then, trim off the ends. For this recipe, slicing the squash into ¼-inch rounds is key. This thickness ensures they cook through without becoming mushy. If your squash are very large, you might consider halving them lengthwise before slicing to create more manageable pieces.
Cooking the Squash
In a large skillet, heat the 2 ½ tablespoons of olive oil over medium heat. You want the oil to be shimmering but not smoking. Add the sliced zucchini and yellow squash to the hot skillet. It’s important not to overcrowd the pan, so you might need to do this in batches. If you add too much squash at once, it will steam rather than sauté, leading to a watery result. Sauté the squash for about 5-7 minutes, stirring occasionally, until they are just beginning to soften. We’re not looking for them to be fully cooked at this stage; we just want to give them a head start and release some of their moisture. Sprinkle in ½ teaspoon of the salt and the ½ teaspoon of pepper while they are cooking. This seasoning will enhance their natural flavors.
Prepping the Casserole Dish
While your squash is doing its initial sauté, it’s a good time to get your casserole dish ready. Lightly grease a 9×13 inch baking dish with a little bit of olive oil or butter. This prevents the casserole from sticking and makes for easier serving. You can also preheat your oven to 375°F (190°C) at this point so it’s ready when your squash is.
Assembling the Casserole
Once the squash has softened slightly, carefully transfer it from the skillet to your prepared casserole dish. Spread the squash out in an even layer. Now, let’s create that irresistible topping! In a small bowl, combine the ⅓ cup of grated Parmesan cheese, the ⅓ cup of gluten-free Panko breadcrumbs, the remaining ¾ teaspoon of salt, and the ¼ teaspoon of garlic powder. Stir these ingredients together until they are well combined. This mixture will form a golden-brown, crispy crust over the tender vegetables.
Creating the Topping and Baking
Evenly sprinkle the Parmesan and Panko mixture over the squash in the casserole dish. Make sure to cover the squash as much as possible to ensure a delicious crunchy topping. For an extra burst of freshness and color, sprinkle the 2 tablespoons of finely chopped fresh parsley over the top of the casserole. This adds a lovely herbaceous note that complements the savory flavors beautifully.
Place the casserole dish in your preheated oven and bake for 20-25 minutes, or until the topping is golden brown and the squash is tender. You should see the breadcrumbs turning a lovely toasted hue and the cheese bubbling slightly. Keep an eye on it to prevent the topping from burning. The aroma that fills your kitchen will be incredible!
Serving Your Delicious Casserole
Once the Zucchini and Squash Casserole is beautifully browned and bubbling, carefully remove it from the oven. Let it rest for about 5-10 minutes before serving. This allows the flavors to meld together and makes it easier to scoop out. This casserole is wonderful served warm alongside grilled chicken, fish, or a hearty steak. It also makes a fantastic vegetarian main course. Enjoy the delightful textures and flavors of this easy and satisfying summer vegetable dish!

Incorporating cooked beef bacon bits or crumbled sausage can also elevate this dish into something even more decadent.
Frequently Asked Questions:
Can I make this Zucchini and Squash Casserole ahead of time?
Yes, absolutely! You can assemble the casserole up to 24 hours in advance. Cover it tightly with plastic wrap and refrigerate. When ready to bake, you may need to add a few extra minutes to the baking time since it will be starting from cold. I recommend letting it sit at room temperature for about 20-30 minutes before baking for more even cooking.
What can I substitute for the cream of mushroom soup?
If you’re not a fan of cream of mushroom soup or have dietary restrictions, you can easily substitute it with an equal amount of homemade béchamel sauce, a can of condensed cream of celery soup, or even a mixture of sour cream and mayonnaise for a tangier flavor profile. Ensure the substitute is well-seasoned before adding it to the casserole.
My casserole seems watery. How can I prevent this in the future?
A common issue with zucchini and squash is their high water content. To combat this, I highly recommend salting the sliced vegetables and letting them sit in a colander for about 20-30 minutes before cooking. Gently squeeze out any excess moisture before adding them to the casserole. This step makes a significant difference in achieving a less watery result.
