Cooking Instructions
Let’s get started on this delicious and easy casserole. The key to a great texture is ensuring the squash is cooked through but not mushy, and the topping is golden and crisp.
1.
Prepping the Squash
Begin extract by washing your zucchini and yellow squash thoroughly. Trim off the ends. The most crucial step here is slicing the squash uniformly into about ¼-inch thick rounds. This ensures even cooking. If your squash are very large, you might want to remove some of the seeds, especially from the zucchini, as they can release excess moisture. You can do this by scooping them out with a spoon before slicing. In a large bowl, combine the sliced squash with 1 tablespoon of the olive oil, 1 teaspoon of the salt, and ½ teaspoon of pepper. Toss everything together gently to ensure each slice is lightly coated.
2.
Pre-baking the Squash for Texture
To prevent a watery casserole, I like to pre-bake the squash slightly. This helps to release some of its moisture before it goes into the final casserole dish. Spread the seasoned squash slices in a single layer on one or two large baking sheets. Don’t overcrowd the pans, as this will cause the squash to steam rather than roast. We’re aiming for a slight softening, not full cooking. Bake in a preheated oven at 400°F (200°C) for about 10-12 minutes, or until the squash pieces are just starting to soften and appear slightly translucent. Keep an eye on them, as they can go from perfectly softened to overcooked very quickly.
3.
Preparing the Crispy Topping
While the squash is in the oven, let’s prepare the irresistible topping. In a small bowl, combine the Panko breadcrum extractbs, grated Parmesan cheese, garlic powder, and the remaining ¼ teaspoon of salt. If you’re using gluten-free Panko, ensure it’s a good quality one that toasts up nicely. Add the remaining 1 ½ tablespoons of olive oil to this mixture and stir until the breadcrum extractbs and cheese are evenly moistened. This oil will help the topping achieve that perfect golden-brown crispiness. Finally, stir in the finely chopped fresh parsley for a burst of color and fresh flavor. The parsley adds a lovely herbaceous note that complements the richness of the cheese.
4.
Assembling the Casserole
Once the squash has been pre-baked and is slightly softened, carefully remove it from the oven. You can either transfer the slightly softened squash back into the large bowl you used earlier, or gently spread it directly into a 9×13 inch baking dish. If you’re using a baking dish, ensure it’s lightly greased or sprayed with cooking spray to prevent sticking. Layer the squash evenly in the dish. There’s no need to arrange it perfectly; a rustic arrangement is perfectly fine.
5.
Topping and Final Bake
Now, sprinkle the prepared Panko and Parmesan topping evenly over the squash. Make sure to cover the entire surface to create a cohesive, delicious crust. Gently press the topping down slightly so it adheres to the squash. Place the casserole dish back into the 400°F (200°C) oven. Bake for another 15-20 minutes, or until the topping is golden brown and crispy, and the squash is tender. You should see the edges of the topping bubbling and turning a beautiful golden hue. Allow the casserole to rest for a few minutes before serving. This helps the flavors meld and makes it easier to portion. Enjoy this wonderfully simple yet incredibly flavorful Zucchini and Squash Casserole!

Frequently Asked Questions:
Can I make this casserole ahead of time?
Absolutely! You can assemble the Zucchini and Squash Casserole up to a day in advance. Cover it tightly and refrigerate.
