Ingredients

Zucchini and Yellow Squash: Of course fresh zucchini and yellow squash are the main ingredients! Select ones that are similar size so the rounds will all fit nicely in the baking dish. You could use a combination of both zucchini and yellow squash, or just one or the other.
Olive Oil: To drizzle over the zucchini and spray over the breadcrumbs so they bake to perfection. I like Delallo Extra Virgin Olive Oil.
Panko Bread Crumbs: Plain panko bread crumbs are the base for the crispy topping.
Grated Parmesan Cheese: For added flavor in the topping.
Seasoning: Dried parsley, garlic powder, salt and pepper.
Lemon Wedges: For serving. I love to squeeze a wedge of lemon over this dish to brighten it up, however it’s also great on its own!

Step-By-Step Instructions

You won’t believe how easily and quickly this Zucchini and Squash Bake comes together. It’s assembled, then oven roasted until the summer squash is tender and the bread crumb topping is crispy.

Preheat the oven to 375°F. Lightly spray a medium casserole dish or baking sheet with olive oil.
Arrange the zucchini and yellow squash so they are slightly overlapping. Drizzle the tops with olive oil.
In a small bowl, whisk together the panko, parmesan cheese, parsley, garlic powder, salt and pepper. Sprinkle over the top of the zucchini and yellow squash. Lightly spray with olive oil.
Bake covered for 10 minutes. Remove the cover, then bake uncovered for 10-15 more minutes, until desired tenderness. If you want to make the topping extra golden, place under the broiler (be sure to use a broiler safe baking dish) for 1-2 more minutes. Keep an eye on it, as it will turn golden fast!
Serve with lemon wedges (optional) and enjoy!

To Store: Refrigerate in an airtight container for up to 3 days. For the best texture, reheat in a 350°F oven until heated through.

Variations

I like the simplicity of this squash casserole, however if you want to change it up, here are some recommendations.

Serve topped with fresh herbs. Instead of dried parsley, top with fresh parsley, thyme, basil, or whatever other fresh herbs you have on hand.
Drizzle pesto or marinara over the zucchini and squash. You can drizzle either one over the zucchini and squash before topping it with the breadcrumb mixture for even more added flavor.
Top with tomatoes. This dish would also be great topped with some fresh or roasted cherry tomatoes.
Make it gluten free. To make it gluten free, be sure to use gluten free panko bread crumbs.

Serving Suggestions

My favorite way to serve this Zucchini and Squash Bake is as a summer veggie side dish. It goes great with just about anything, including grilled chicken, pasta, steak, and shrimp.

Serve it over spaghetti with your favorite sauce for a complete meal.
