Ingredients

For the Zucchini Bake

• 4 medium zucchini, sliced into rounds
• 2 tablespoons olive oil
• 3 garlic cloves, minced
• ¾ cup grated Parmesan cheese, divided
• ½ cup panko breadcrumbs
• 1 teaspoon Italian seasoning
• ½ teaspoon garlic powder
• ½ teaspoon kosher salt
• ¼ teaspoon black pepper
• ¼ teaspoon red pepper flakes, optional
• 2 tablespoons chopped fresh parsley

Ingredient Notes

Zucchini

Medium zucchini works best because it has fewer seeds and less water than oversized zucchini. Slice it evenly so the bake cooks at the same rate.

Parmesan

Freshly grated Parmesan gives the best flavor and melts into the topping better than shelf-stable grated cheese.

Panko Breadcrumbs

Panko creates a lighter, crunchier topping. Regular breadcrumbs can work, but the texture will be finer.

Garlic

Fresh garlic gives the strongest flavor. Garlic powder adds extra savory depth to the breadcrumb topping.

Red Pepper Flakes

These are optional, but a small pinch adds gentle heat without making the dish spicy.

How to Make Garlic Parmesan Zucchini Bake

1. Prepare the Oven and Baking Dish

Preheat the oven to 400°F.

Lightly grease a medium baking dish with olive oil or cooking spray.

2. Slice and Season the Zucchini

Wash and dry the zucchini.

Slice it into even rounds, about ¼ inch thick.

Place the zucchini slices in a large bowl with olive oil, minced garlic, salt, black pepper, Italian seasoning, and red pepper flakes if using.

Toss until the slices are evenly coated.

3. Arrange in the Baking Dish

Layer the seasoned zucchini slices in the prepared baking dish.

Slightly overlap the rounds so they bake evenly while still allowing some edges to brown.

4. Add the Parmesan Topping

In a small bowl, mix the panko breadcrumbs, ½ cup Parmesan cheese, garlic powder, and a little extra black pepper.

Sprinkle the mixture evenly over the zucchini.

Finish with the remaining Parmesan cheese.

5. Bake Until Golden

Bake uncovered for 20 to 25 minutes, or until the zucchini is tender and the topping is golden.

For extra browning, broil for 1 to 2 minutes at the end, watching carefully so the topping does not burn.

Garnish with fresh parsley before serving.

Expert Tips

Slice Evenly

Even slices help the zucchini cook at the same speed and prevent some pieces from becoming mushy.

Don’t Overcrowd the Dish

A slightly wider baking dish helps moisture evaporate and keeps the topping crisp.

Use Panko for Crunch

Panko breadcrumbs create the best golden topping.

Broil Carefully

Broiling adds color fast, but the topping can burn quickly. Watch it closely.

Easy Variations

Cheesy Mozzarella Zucchini Bake

Add shredded mozzarella before the breadcrumb topping for a meltier, more casserole-style dish.

Tomato Zucchini Bake

Layer thin tomato slices between the zucchini for extra color and summer flavor.

Italian Zucchini Bake

Add marinara sauce to the bottom of the baking dish and top with extra Parmesan.

Low-Carb Version

Skip the breadcrumbs and use extra Parmesan with crushed pork rinds or almond flour.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days.

Reheat in the oven at 350°F until warmed through. For the best texture, avoid microwaving if possible, since the topping may soften.

This recipe is best served fresh because zucchini naturally releases moisture as it sits.

Freezing is not recommended, as thawed zucchini can become watery.

Frequently Asked Questions

How do I keep zucchini bake from getting watery?

Use medium zucchini, avoid overcrowding the pan, and bake uncovered so moisture can evaporate.

Can I make this ahead of time?

You can slice the zucchini and prepare the topping ahead, but assemble and bake right before serving for the best texture.

Can I use yellow squash?

Yes. Yellow squash works well and can be mixed with zucchini for extra color.

Can I make this gluten-free?

Yes. Use gluten-free panko breadcrumbs or skip the breadcrumbs and use extra Parmesan.

What cheese works besides Parmesan?

Mozzarella, provolone, Asiago, or an Italian cheese blend can all work well.
