Ingredients
For the Zucchini Egg Mixture
2 medium zucchini, grated
5 large eggs
1 cup shredded mozzarella cheese
½ cup grated Parmesan cheese
1 small onion, finely diced
2 garlic cloves, minced
¼ cup all-purpose flour or oat flour
1 tsp dried oregano
½ tsp garlic powder
½ tsp black pepper
½ tsp salt, or to taste
2 tbsp fresh parsley, chopped
1 tbsp olive oil
For the Topping
½ cup shredded mozzarella cheese
2 tbsp grated Parmesan cheese
A little dried oregano
Fresh parsley, for garnish
Instructions
Prepare the Zucchini
Preheat the oven to 375°F (190°C).
Grate the zucchini using the large side of a box grater.
Place the grated zucchini in a clean kitchen towel or cheesecloth and squeeze firmly to remove as much excess moisture as possible.
This step is important because zucchini naturally contains a lot of water. Removing the excess liquid helps the egg slice set properly instead of becoming watery.
Prepare the Onion and Garlic
Heat the olive oil in a small skillet over medium heat.
Add the diced onion and cook for 3–4 minutes until softened.
Add the minced garlic and cook for another 30 seconds until fragrant.
Remove from the heat and allow the mixture to cool slightly.
Make the Egg Mixture
In a large mixing bowl, whisk the eggs until lightly beaten.
Add the squeezed zucchini, cooked onion and garlic, mozzarella, Parmesan, flour, oregano, garlic powder, black pepper, salt, and fresh parsley.
Mix gently until all the ingredients are evenly distributed.
The mixture should be moist but not excessively watery.
Prepare the Baking Dish
Lightly grease an approximately 8 x 8-inch or similar-sized baking dish with olive oil.
For easier removal, you can also line the dish with parchment paper, leaving a little overhang on the sides.
Pour the zucchini and egg mixture into the prepared dish.
Spread it evenly and smooth the surface with a spatula.
Add the Cheese Topping
Sprinkle the remaining mozzarella and Parmesan evenly over the top.
Add a light sprinkle of oregano for extra flavor.
Bake Until Golden
Place the dish in the preheated oven.
Bake for approximately 30–35 minutes, or until the center is completely set and the top is golden and bubbling.
If the cheese begins browning too quickly, loosely cover the dish with foil during the final part of baking.
Rest and Slice
Remove the baked zucchini egg slice from the oven and let it rest for 8–10 minutes.
This allows the eggs and cheese to firm up, making it easier to cut into neat slices.
Garnish with fresh parsley and serve warm.
Tips
Squeeze the Zucchini Well
This is the most important step in the recipe. Excess zucchini water can make the finished dish soft or watery. Squeeze the grated zucchini several times until very little liquid comes out.
Use Freshly Grated Cheese
Freshly shredded mozzarella and Parmesan melt smoothly and give the dish a better texture and flavor.
Do Not Overmix the Eggs
Whisk the eggs just until combined. Excessive whisking is unnecessary and can affect the texture of the finished bake.
Choose the Right Baking Dish
A smaller baking dish produces a thicker, softer slice, while a larger dish creates a thinner bake with more golden edges.
Let It Rest Before Cutting
Allowing the bake to rest for several minutes after coming out of the oven makes a big difference. Cutting immediately can cause the slices to fall apart.
Adjust the Seasoning
Zucchini has a mild flavor, so herbs and seasoning are important. Taste the mixture before baking and adjust the salt, pepper, and oregano to your preference.
Watch the Baking Time
Every oven is slightly different. The center should look set rather than liquid, and a knife inserted into the middle should come out mostly clean.
Variations
Add Feta Cheese
Replace part of the mozzarella with crumbled feta for a delicious Mediterranean twist. Feta adds a salty, tangy flavor that pairs beautifully with zucchini.
Add Spinach
Finely chop fresh spinach and sauté it briefly before adding it to the mixture. Make sure to squeeze out excess moisture.
Add Fresh Herbs
Fresh dill, basil, parsley, or chives can be added for extra freshness.
Make It Spicy
Add a pinch of red pepper flakes or finely chopped chili peppers to the egg mixture.
Add Sun-Dried Tomatoes
Finely chopped sun-dried tomatoes add a concentrated sweet and savory flavor that works especially well with zucchini and cheese.
Use Cheddar Cheese
For a richer, sharper flavor, replace some or all of the mozzarella with shredded cheddar.
Make It Low-Carb
Replace the flour with almond flour or simply omit it if your zucchini has been squeezed very thoroughly. The texture will be slightly softer but still delicious.
Add Cooked Chicken
For a more filling meal, fold in finely chopped cooked chicken. This turns the zucchini egg slice into a higher-protein lunch or dinner.
Q&A
Why is my zucchini egg bake watery?
The most common reason is excess moisture in the zucchini. Grated zucchini should be squeezed very well before being added to the egg mixture.
Can I use frozen zucchini?
Fresh zucchini is recommended, but frozen zucchini can work if it is completely thawed and squeezed very thoroughly to remove excess water.
Can I make this recipe without flour?
Yes. Flour helps give the slice structure, but you can omit it if you prefer. Make sure the zucchini is well drained.
Can I prepare this ahead of time?
Yes. You can bake it several hours ahead and refrigerate it until serving. It can be served warm, at room temperature, or gently reheated.
Can I eat zucchini egg slices cold?
Absolutely. They are delicious cold or at room temperature, making them convenient for lunch boxes, picnics, and meal prep.
How do I store leftovers?
Place cooled slices in an airtight container and refrigerate for up to 3 days.
Can I freeze baked zucchini egg slices?
Yes. Allow them to cool completely, cut them into individual portions, wrap well, and freeze. Thaw in the refrigerator and reheat in the oven for the best texture.
What can I serve with this zucchini bake?
Serve it with a fresh tomato and cucumber salad, Greek salad, roasted potatoes, avocado, fresh fruit, or a simple green salad.
