4 medium zucchinis, sliced
1 cup shredded mozzarella cheese
1 cup shredded cheddar cheese
3 large eggs
1 sweet onion, finely chopped
1 teaspoon garlic powder

Directions

Preheat the oven: Set your oven to 375°F (190°C). Lightly grease a medium-sized baking dish with olive oil.
Prepare the zucchini: Slice the zucchinis into thin rounds and place them in a mixing bowl. Season with salt, pepper, and garlic powder, tossing to coat evenly.
Cook the onions: In a skillet, heat 2 tablespoons of olive oil over medium heat. Add the finely chopped sweet onion and sauté until soft and translucent, about 5 minutes. Remove from heat.
Mix the casserole: In a large bowl, whisk the eggs. Stir in the sautéed onions, shredded mozzarella, shredded cheddar, and seasoned breadcrumbs. Add the zucchini slices and gently mix until everything is combined.
Assemble: Pour the mixture into the prepared baking dish, spreading evenly.
Bake: Bake for 35–40 minutes until the top is golden brown and the casserole is set. Let it cool slightly before serving.

FAQs

Can I prepare this casserole ahead of time?

Yes! Assemble the casserole a day before, cover it tightly, and refrigerate. Bake it just before serving.

Can I use frozen zucchini instead of fresh?

It’s best to use fresh zucchini to avoid excess moisture, but if using frozen, thaw and drain well before mixing.

What can I substitute for seasoned breadcrumbs?

Use plain breadcrumbs mixed with Italian seasoning or add extra garlic powder and herbs.

Can I make this recipe dairy-free?

Try substituting the cheeses with dairy-free alternatives, but the texture may vary slightly.

How do I prevent the casserole from becoming watery?

Salt the zucchini slices and let them drain on paper towels before mixing to remove excess moisture.
