Ingredients You’ll Need

The beauty of Quick Baked Zucchini Parmesan Casserole lies in how a short list of humble ingredients transforms into a dish bursting with flavor and texture. Each addition brings its own special touch, so be sure not to skip the fresh veggies or the trio of cheeses!

• Zucchini: The main star; choose firm, medium zucchinis for that perfect tender bite.
• Salt: Helps extract moisture from the zucchini, ensuring your casserole stays hearty, not soggy.
• Onion: Adds a gentle layer of sweetness and complements the savory cheeses beautifully.
• Garlic: Three cloves offer just the right amount of aromatic punch without overpowering the dish.
• Eggs: Binds everything together, resulting in a casserole that slices cleanly.
• Parmesan cheese: Offers a savory, nutty brightness and tops the casserole with a golden finish.
• Mozzarella cheese: Melts into gooey, stringy pockets tucked between every bite.
• Cheddar cheese: Balances the flavors with its sharpness, while giving the casserole a rich hue.
• Panko crumbs: Create that signature crispy topping you’ll crave in every forkful.
• Melted salted butter: Binds the breadcrumbs and lends a touch of richness to the golden crust.

How to Make Quick Baked Zucchini Parmesan Casserole

Step 1: Preheat the Oven and Prepare the Baking Dish

Begin by firing up your oven to 375°F (190°C). While it warms up, give your favorite 1 ½-quart baking dish a quick grease. This step isn’t just about preventing sticking; it guarantees easy serving and minimal clean-up later, so don’t skip it!

Step 2: Remove Excess Water from Zucchini

Now for the magic: sprinkle your shredded zucchini with salt in a colander and let it rest for a solid 10 minutes. You’ll see the water start to bead up almost right away. When time’s up, wrap those zukes in a clean kitchen towel and squeeze with gusto—right over the sink. Wringing out every bit of water makes all the difference between a fluffy, cheesy casserole and a puddle at the bottom of your dish.

Step 3: Mix Casserole Ingredients

Grab a large mixing bowl and combine your now-thirsty zucchini with the chopped onion, minced garlic, lightly beaten eggs, ½ cup of Parmesan, mozzarella, and cheddar. Mix until everything is happily mingling. Scoop and gently press the mixture into your prepared dish, smoothing out the top so it bakes evenly.

Step 4: Bake the Zucchini Casserole

Pop your dish onto the middle rack of the oven and bake uncovered for 20 minutes. This initial bake allows the eggs and cheese to set, turning our humble zucchini mixture into a unified, delectable base.

Step 5: Prepare the Breadcrumb Topping

As the casserole bakes, stir together the panko, melted salted butter, and final two tablespoons of Parmesan in a small bowl. You want every crumb to be glistening and evenly coated—it’s the key to that signature crunchy finish atop your Quick Baked Zucchini Parmesan Casserole.

Step 6: Add Topping and Finish Baking

Once 20 minutes have passed, carefully remove your casserole from the oven. Sprinkle the buttery breadcrumb-parmesan topping over the surface, paying special attention to the corners for extra crunch. Slide the dish back into the oven and bake another 5 to 10 minutes, or until the topping is beautifully golden and irresistibly crisp.

Step 7: Serve and Enjoy

Let your Quick Baked Zucchini Parmesan Casserole cool for a few minutes before serving—this makes it easier to slice, and lets the cheese set to the perfect creamy texture. Dish it out and watch that cheesy goodness disappear before your eyes!

Make Ahead and Storage

Storing Leftovers

Leftovers of this casserole are a gift! Just cover your cooled dish with plastic wrap or foil, or transfer slices to an airtight container. It will keep in the refrigerator for up to three days, making it a perfect lunchbox or snack option.

Freezing

Although zucchini casseroles are best enjoyed fresh, you can freeze this dish if you have extras. Wrap individual portions tightly in plastic wrap and then foil, or store in freezer-safe containers. Freeze for up to one month. Thaw in the refrigerator overnight before reheating for best results.

Reheating

To bring back the crispy topping, reheat your Quick Baked Zucchini Parmesan Casserole in a 350°F (175°C) oven for about 10-15 minutes until warmed through. If you’re in a hurry, a microwave works as well, though the topping will be a bit softer. Either way, each bite is still just as comforting and delicious!

FAQs

Can I use yellow squash instead of zucchini?

Absolutely! Yellow squash is a great substitute or addition here. It brings a touch of sweetness and blends seamlessly with the flavors of this casserole. Just be sure to remove excess moisture the same way you would with zucchini.

Is there a gluten-free option for the topping?

Yes, you can easily swap out the panko for gluten-free breadcrumbs or even crushed gluten-free crackers. The result will still be golden and crunchy, so no one misses out!

What’s the best way to shred the zucchini?

A box grater or food processor works best for quick, even shreds. No need to peel the zucchini; the skin adds lovely color and extra nutrients to your Quick Baked Zucchini Parmesan Casserole.

Can I prep this casserole ahead of time?

Definitely! You can shred and salt your zucchini in advance, and assemble the casserole up to the initial bake. Just cover and refrigerate it until you’re ready to bake, then add the topping just before the final bake for maximum crispiness.

Can I add more vegetables?

Of course! Chopped spinach, sweet peppers, or grated carrot are delicious additions to Quick Baked Zucchini Parmesan Casserole. Just be sure to squeeze out the moisture from any extra veggies to keep the casserole from getting watery.
