How to Make Flavor-Packed Vegetarian Zucchini Slice (Step-by-Step)
This dish is easy to prepare and packed with flavors that everyone will love.
Step 1: Prepare the Zucchini
Start by grating the zucchinis using a box grater or a food processor. I love the texture that a box grater imparts-it gives a more rustic feel. After grating, place the zucchini in a clean kitchen towel and squeeze out any excess moisture. This helps prevent a soggy slice.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine the flour, baking powder, baking soda, salt, and black pepper. Give it a vigorous whisk until all the dry ingredients are mixed evenly-you want a well-airy blend that will help your slice rise beautifully.
Step 3: Combine the Wet Ingredients
In another bowl, beat the eggs until frothy, then add the ricotta cheese, Parmesan, and chopped herbs. Take a moment to appreciate the fragrant herbs; they really brighten the entire dish. Mix until creamy and well combined.
Step 4: Fold It All Together
Gently incorporate the grated zucchini, sweet corn, diced onion, and minced garlic into the wet mixture. Then, carefully fold this blend into the dry mixture. I use a spatula, folding the batter until just combined-this way, you retain some of the airiness, which is key for the perfect rise.
Step 5: Bake the Slice
Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with olive oil, then pour in the batter, spreading it evenly. Bake for about 40-45 minutes, or until the center is set and bounces back when pressed lightly. I love the moment when I can see the golden top and inhale the delightful scent of baked zucchini. It'll be slightly jiggly in the center-this is normal!
Step 6: Cool and Serve
Once baked, allow the zucchini slice to cool slightly before cutting it into squares. This slice will be beautifully firm while still being tender inside, making it a perfect addition to any holiday spread.

Common Mistakes to Avoid
- Don't skip squeezing the zucchini: This can lead to a watery slice.
- Avoid over-mixing: This can result in a dense texture instead of a light, airy one.
- Don't leave out the herbs: They bring so much flavor and brightness to this dish.
Tips and Tricks for Success
- Serve warm or at room temperature; it holds up wonderfully and will keep the guests coming back for more.
- Pair with a light salad or a dollop of yogurt for added creaminess.
- Use a box grater for a rustic texture in the zucchini slice.
- Let the slice cool slightly before cutting for firmer squares.
Variations
- Substitute zucchini with yellow squash or carrots for a different twist.
- Use feta cheese instead of ricotta for a saltier flavor.
- Add cooked spinach or kale for an extra veggie boost.
- Incorporate sun-dried tomatoes or olives for a Mediterranean flair.
How to Serve
- Cut into squares and serve as a side dish at gatherings.
- Enjoy it chilled as part of a picnic spread.
- Serve alongside a light greens salad.
- Top with yogurt or tzatziki for added richness.

Make Ahead and Storage
- Make Ahead: Prepare the mixture a day in advance and store it in the refrigerator until ready to bake.
- Storage: Wrap leftover slices in plastic wrap or store them in an airtight container in the refrigerator. They will keep well for about 3-4 days.
- Reheating: Reheat slices in the oven at 350°F (175°C) for about 10-15 minutes, or until warmed through.
- Freezing: You can freeze the zucchini slice for up to 2 months. Thaw in the refrigerator overnight before reheating.
