Cooking Instructions
Preparing this zucchini and squash casserole is a straightforward process that yields impressive results. We’ll start by prepping the vegetables, then move on to creating a flavorful coating, and finally, bake it to golden perfection.
1. Prepare the Squash
Begin extract by thoroughly washing your zucchini and yellow squash. It’s important to trim off the ends of both types of squash. Then, using a sharp knife or a mandoline slicer, cut the squash into approximately ¼-inch thick slices. Uniformity in slicing is key here, as it ensures that all the squash pieces cook evenly. If you’re using a mandoline, be sure to use the safety guard to protect your fingers. Aim for slices that are not too thin, or they might become mushy, and not too thick, or they may not cook through in the allotted time. Once sliced, place the squash in a large bowl. Sprinkle about ½ teaspoon of the salt over the squash slices. This initial salting helps to draw out some of the excess moisture from the squash, preventing the casserole from becoming watery during baking. Gently toss the squash with the salt, ensuring each slice is lightly coated. Let the squash sit for about 10-15 minutes. You’ll notice that a good amount of liquid will have accumulated in the bowl.
2. Drain and Season the Squash
After the squash has had a chance to sit and release its moisture, it’s time to get rid of that liquid. Carefully drain the squash in a colander, pressing down gently with your hands or a spoon to squeeze out as much water as possible. The more moisture you can remove now, the less watery your final casserole will be. Once drained, return the squash to the clean, dry bowl. Now, it’s time to season it. Add the remaining ¾ teaspoon of salt and the ½ teaspoon of pepper. Drizzle in 1 tablespoon of the olive oil. Toss everything together gently to ensure the squash is evenly seasoned. This step adds a foundational layer of flavor to the vegetables themselves.
3. Prepare the Topping
While the squash is resting, we’ll prepare the delicious topping that will give our casserole that irresistible crunch. In a separate medium-sized bowl, combine the grated Parmesan cheese, the gluten-free Panko breadcrum extractbs, and the garlic powder. Add the remaining 1 ½ tablespoons of olive oil to this mixture. This helps to bind the ingredients together and ensures the breadcrum extractbs toast up beautifully, creating a golden-brown and crispy crust. Stir everything together with a fork until the breadcrum extractbs are evenly coated with the cheese, garlic powder, and olive oil. This mixture will be sprinkled over the squash before baking. The garlic powder adds a subtle savory note, while the Parmesan cheese provides a salty, nutty flavor that complements the mildness of the squash perfectly.
4. Assemble the Casserole
Now, it’s time to bring all the components together. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a 9×13 inch baking dish with a little extra olive oil or cooking spray to prevent sticking. Carefully arrange the seasoned squash slices in a single layer in the prepared baking dish. Try to overlap them slightly, but avoid piling them too high, as this can lead to uneven cooking. Once the squash is evenly distributed, sprinkle the prepared Panko and Parmesan topping evenly over the entire surface of the squash. Make sure to cover as much of the squash as possible with the breadcrum extractb mixture for maximum crunch.
5. Bake to Golden Perfection
Place the assembled casserole dish in the preheated oven. Bake for approximately 25 to 30 minutes, or until the topping is golden brown and crispy, and the squash is tender when pierced with a fork. The exact baking time may vary slightly depending on your oven and the thickness of your squash slices. Keep an eye on it during the last 10 minutes to ensure the breadcrum extractbs don’t burn. Once it’s out of the oven, let the casserole rest for about 5 minutes before serving. This resting period allows the flavors to meld and makes it easier to serve. Just before you present it to the table, sprinkle the finely chopped fresh parsley over the top. The fresh parsley not only adds a beautiful pop of color but also provides a burst of fresh, herbaceous flavor that cuts through the richness of the casserole. This Zucchini and Squash Casserole is best served warm and is a wonderful accompaniment to grilled chicken, fish, or beef chops. Enjoy this taste of summer!

Frequently Asked Questions:
Can I use other types of squash in this recipe?
Absolutely! While zucchini and yellow squash are classic, feel free to experiment with other summer squash varieties like pattypan squash. Just ensure they are cut into similar-sized pieces for even cooking. You could even add a small amount of diced butternut squash for a slightly sweeter, nuttier flavor, though it may require a slightly longer initial steaming time.
How can I make this casserole dairy-free or vegan?
For a dairy-free or vegan version, you can easily swap out the dairy cheese for your favorite plant-based shredded cheese blend. For the creamy sauce, consider using full-fat coconut milk or a cashew cream base, and bind it with a bit of nutritional yeast for that cheesy essence. You might also want to add a tablespoon of cornstarch or tapioca starch to thicken the sauce if needed.
Can I prepare this casserole ahead of time?
Yes, you can definitely prepare this Zucchini and Squash Casserole ahead of time! Assemble the casserole up to the point of baking, then cover it tightly and refrigerate for up to 24 hours. When ready to bake, you may need to add a few extra minutes to the baking time to ensure it’s heated through. This makes it a fantastic option for meal prepping or for reducing stress on busy entertaining days.
