How to Make Crispy Zucchini Casserole

Preheat: Begin by preheating your oven to 375°F (190°C). This is essential for getting that golden-brown topping just right! Don’t forget to brush the bottom of a 9×12 baking dish with a little olive oil, ensuring nothing sticks.
-
Drain: Set your sliced zucchini and onions on a clean kitchen towel to drain excess moisture. This step helps prevent a soggy casserole and ensures every layer stays flavorful.
-
Mix: In a large bowl, combine the drained zucchini slices and onions with the basil pesto. Make sure everything is evenly coated; this herby mix adds depth to your casserole.
-
Layer: Pour a generous layer of marinara sauce into the bottom of your prepared dish. Follow this with the zucchini mixture, spreading it evenly to create a beautiful base that will bake into perfection.
-
Top: Sprinkle panko bread crumbs, grated Parmesan cheese, and red pepper flakes over the zucchini mixture. Drizzle with olive oil to aid in achieving that crispy topping you’re dreaming of!
-
Bake: Place the casserole in the preheated oven and bake for about 25 minutes. You’ll know it’s ready when the topping is golden brown, and the zucchini should be tender but not mushy. For an extra crispy finish, consider turning on the broiler for the last few minutes!
-
Cool: Let the casserole cool for 20 minutes before slicing and serving. This resting time allows the flavors to meld and makes for easy serving!

Crispy Zucchini Casserole Recipe FAQs
What is the best way to select zucchini for the casserole?
When selecting zucchini, look for firm, vibrant, and unblemished ones. I recommend choosing smaller zucchinis as they’re usually sweeter and have fewer seeds, making them perfect for this casserole. The same goes for yellow squash; look for medium-sized ones to ensure they are tender and flavorful.
How should I store leftover crispy zucchini casserole?
After cooling, store any leftovers in an airtight container in the fridge. This dish can last for up to 3 days. To reheat, place it in a preheated oven at 350°F (175°C) for about 15-20 minutes to keep that delightful crispiness intact!
Can I freeze the crispy zucchini casserole?
Absolutely! For optimal freshness, I suggest freezing the casserole before baking. Wrap it tightly in plastic wrap and then in aluminum foil, which helps to prevent freezer burn. It can be stored for up to 3 months. When you’re ready to bake it, thaw it in the fridge overnight and then follow the baking instructions.

What if my casserole turns out soggy?
Don’t fret! If your casserole is soggy, it usually means the zucchini didn’t drain sufficiently. Next time, ensure you pat the sliced zucchini and onions dry with a kitchen towel after draining to remove excess moisture. Alternatively, you can sprinkle a bit more panko on top to absorb any liquids while baking, enhancing the crispiness.
Is this dish suitable for my dietary needs?
Yes! This crispy zucchini casserole is incredibly versatile. For a vegan alternative, simply swap out the Parmesan cheese for vegan Parmesan and use vegan pesto. Additionally, gluten-free panko can replace regular panko if you’re avoiding gluten. Always double-check any store-bought ingredients for allergens, just to be safe!
How long does it take to prepare the crispy zucchini casserole?
From start to finish, you should allocate about 1 hour. This includes approximately 15 minutes for preparation, like slicing and draining the zucchini and onions, followed by 25 minutes of baking.
