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)

Cooking Instructions

This casserole comes together with minimal fuss, making it an ideal weeknight meal. The key to a great zucchini and squash casserole is to properly prepare the vegetables to avoid a watery dish. We’ll start by salting the squash, which draws out excess moisture.

1. Prepare the Squash and Draw Out Moisture: Begin by washing your zucchini and yellow squash thoroughly. Trim off the ends of both types of squash. Using a sharp knife or a mandoline slicer, cut the squash into ¼-inch thick rounds. In a large bowl, toss the sliced squash with 1 teaspoon of the salt. This is a crucial step to prevent your casserole from becoming watery and mushy. Let the squash sit for at least 20-30 minutes, allowing it to release its excess moisture. You’ll notice a pool of liquid forming at the bottom of the bowl.

2. Drain and Squeeze the Squash: After the squash has rested and released its moisture, it’s time to drain it effectively. Carefully pour the squash and the liquid into a colander set over a sink or another bowl. Gently press down on the squash with the back of a spoon or your hands to help squeeze out as much liquid as possible. For even better results, you can transfer small handfuls of the salted squash into a clean kitchen towel or cheesecloth and wring them out firmly. The drier the squash, the better the final texture of your casserole.

3. Preheat Oven and Prepare the Casserole Dish: While the squash is draining, preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with a little olive oil or cooking spray. This will prevent the casserole from sticking and make for easier cleanup.

4. Assemble the Casserole Layers: Once the squash is drained and squeezed dry, return it to the now-empty large bowl. Add the 2 ½ tablespoons of olive oil, ½ teaspoon of pepper, and the remaining ¼ teaspoon of salt. Toss everything together gently to evenly coat the squash slices. Arrange the seasoned squash in a single, even layer in the prepared baking dish. Try not to overlap the slices too much, as this allows for more even cooking.

5. Create the Crispy Topping: In a small bowl, combine the ⅓ cup of grated Parmesan cheese, ⅓ cup of Panko breadcrumbs, and ¼ teaspoon of garlic powder. Mix these ingredients together thoroughly. This savory, crunchy topping is what elevates this simple casserole. Sprinkle this breadcrumb and cheese mixture evenly over the top of the squash layer in the baking dish.

6. Bake to Perfection: Place the casserole dish in the preheated oven. Bake for 25-30 minutes, or until the squash is tender when pierced with a fork and the topping is golden brown and crispy. Keep an eye on it towards the end of the baking time to ensure the breadcrumbs don’t burn. The aroma that will fill your kitchen during this time is simply divine!

7. Garnish and Serve: Once the casserole is out of the oven, let it rest for a few minutes before serving. This allows the flavors to meld and the casserole to set slightly. Just before serving, sprinkle the finely chopped fresh parsley over the top. The vibrant green of the parsley adds a beautiful visual appeal and a burst of fresh flavor that complements the rich, savory casserole perfectly. Serve hot as a delightful side dish to grilled chicken, fish, or steak, or enjoy it as a light vegetarian main. This casserole is delicious served immediately, and leftovers (if any!) are also quite good reheated.

Conclusion:

This Zucchini and Squash Casserole is a fantastic way to enjoy the bounty of summer vegetables, or to add a healthy and flavorful side dish to any meal. Its creamy texture, mild flavors, and simple preparation make it a winner for busy weeknights and casual gatherings alike. The combination of tender zucchini and yellow squash, bathed in a savory sauce and topped with a delightful crunch, creates a comforting and satisfying experience that’s surprisingly light.

For a heartier meal, consider stirring in some cooked quinoa or farro. Don’t be afraid to get creative with variations! Adding a sprinkle of your favorite cheese, like cheddar or Gruyère, to the topping will elevate the flavor. You could also incorporate finely diced bell peppers or onions into the vegetable mixture for an extra layer of taste and texture. This Zucchini and Squash Casserole is incredibly versatile, making it a recipe you’ll return to again and again.
