Ingredients for a Perfect Cheesy Zucchini Bake

To make this recipe, you’ll need simple, wholesome ingredients that are probably already in your kitchen. Each element has a purpose, contributing to the texture and richness of the dish.

Ingredients:

• 4 cups sliced zucchini (about 3 medium zucchini)

• 1 teaspoon salt

• 1 cup shredded mozzarella cheese

• ¾ cup sharp cheddar cheese

• ½ cup grated Parmesan cheese

• ½ cup chopped yellow onion

• 2 garlic cloves, minced

• 3 large eggs

• ½ cup heavy cream or whole milk

• ¼ cup all-purpose flour (or almond flour for a low-carb option)

• 1 teaspoon Italian seasoning

How to Make Easy Cheesy Zucchini Bake Step-by-Step

This zucchini bake couldn’t be simpler. Follow these steps, and you’ll have a bubbling, cheesy masterpiece ready to serve.

Step 1: Prepare the Zucchini

Slice the zucchini into thin rounds. Place the slices in a colander, sprinkle with salt, and let them sit for about 10 minutes. This process draws out excess water, preventing your bake from becoming soggy.

After resting, gently pat the zucchini dry with a clean towel.

Step 2: Mix the Filling

In a large bowl, whisk together the eggs, heavy cream, flour, garlic, Italian seasoning, and black pepper. Once combined, stir in the mozzarella, cheddar, Parmesan, onions, and zucchini slices. Mix until the zucchini is evenly coated.

Step 3: Assemble and Bake

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or olive oil. Pour the zucchini mixture into the dish and spread evenly.

Top with additional mozzarella or a blend of cheeses for a more indulgent finish.

Bake for 35–40 minutes, or until the top is golden brown and the center is set. Let the bake rest for 5–10 minutes before serving.

Expert Tips for Success

Even though this is an easy recipe, a few tips can help you elevate your zucchini bake to the next level.

• Drain zucchini well: Water is the enemy of crispy, cheesy bakes. Always salt and drain your zucchini first.

• Don’t skip the resting time: Letting the bake rest before slicing allows it to firm up and set.

• Use freshly grated cheese: Pre-shredded cheese contains anti-caking agents that can affect texture.

• Customize with add-ins: Chopped spinach, crumbled bacon, or sun-dried tomatoes make excellent additions.

Variations of This Zucchini Bake

This easy cheesy zucchini bake recipe is endlessly customizable. Use it as a base and explore new flavors:

Make-Ahead, Storage, and Freezer Instructions

Can I make this ahead of time?

Yes! You can assemble the bake up to 24 hours in advance and store it covered in the fridge. Bake when ready.

How do I store leftovers?
