Ingredients Notes

The beauty of this Cheesy Zucchini Casserole lies in its simplicity. Each ingredient plays a role in creating a dish that’s as comforting as it is delicious.

• Zucchini: The star of the show! Fresh, firm zucchini works best for this casserole. Slice them evenly to ensure they cook through and hold their shape.
• Cheese: A combination of shredded mozzarella and sharp cheddar adds the perfect balance of creamy and tangy flavors. Feel free to mix in parmesan or Monterey Jack for extra depth.
• Breadcrumbs: These create the golden, crispy topping that makes casseroles so irresistible. Use seasoned breadcrumbs or panko for added crunch.
• Eggs: They act as a binder, holding everything together. Be sure to whisk them thoroughly for even distribution.
• Onion and Garlic: These aromatic staples add a subtle depth of flavor to the casserole. Sauté them until translucent for the best results.
• Herbs and Spices: A dash of dried basil and oregano, along with salt and pepper, enhances the zucchini's natural flavor. Fresh parsley makes a lovely garnish.

You’ll also need a medium-sized baking dish and a sharp knife for prepping the zucchini slices.

How to Make This Cheesy Zucchini Casserole

Making this casserole is a straightforward process, perfect for cooks of all skill levels. Here’s a step-by-step guide to get it right every time.

Start by preheating your oven to 375°F (190°C). Grease a medium-sized baking dish with butter or cooking spray and set it aside.

Slice the zucchini into thin, even rounds, about ¼ inch thick. Uniform slices ensure they cook evenly and soak up all the cheesy goodness.

In a skillet, heat a splash of olive oil over medium heat. Sauté diced onion and minced garlic until fragrant and slightly golden. This step elevates the overall flavor of the casserole.

In a large mixing bowl, combine the zucchini slices, sautéed onion and garlic, shredded cheese, whisked eggs, and a sprinkle of basil and oregano. Mix everything until the zucchini is evenly coated in the cheesy mixture.

Pour the zucchini mixture into the prepared baking dish, spreading it out in an even layer. Top with breadcrumbs and a final sprinkle of cheese for that irresistible golden crust.

Bake in the preheated oven for 25-30 minutes or until the top is bubbly and golden brown. Let it rest for 5 minutes before serving to allow the flavors to meld together.

Storage Options

If you have leftovers (though don’t be surprised if there aren’t any!), this Cheesy Zucchini Casserole stores beautifully.

• Refrigerator: Transfer the cooled casserole to an airtight container and store it in the fridge for up to 3 days.
• Freezer: For longer storage, wrap individual portions tightly in plastic wrap, then place them in a freezer-safe bag. It can be frozen for up to 2 months.
• Reheating: To reheat, pop it in a 350°F oven for 10-15 minutes, or microwave individual portions for about 1 minute.

Variations and Substitutions

This casserole is as flexible as it is delicious, making it easy to customize to your preferences or dietary needs.

• Add Protein: Transform it into a main dish by adding cooked, shredded chicken or crumbled sausage to the zucchini mixture.
• Try Different Vegetables: Swap out some of the zucchini for thinly sliced yellow squash, eggplant, or even bell peppers.
• Go Gluten-Free: Use gluten-free breadcrumbs or crushed gluten-free crackers for the topping.
• Cheese Swap: Experiment with different cheeses like gouda, fontina, or pepper jack for a unique flavor profile.
