How to Make Cheesy Baked Zucchini Slice Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 180°C (356°F). Grease a rectangular baking dish, around 20×30 cm, then line it with parchment paper to ensure your slice lifts out cleanly after baking. Setting up your tools properly lays the foundation for your perfect cheesy baked zucchini slice.
Step 2: Mix the Vegetables and Cheese
In a large bowl, combine your grated zucchinis along with finely chopped onion, grated cheddar, and parmesan cheeses. This colorful mix is the heart of your dish, blending the tender, watery zucchini with rich, flavorful cheeses.
Step 3: Add the Flour
Sprinkle the self-raising flour over the vegetable and cheese mixture. Stir well to coat every bite with flour, which will help absorb moisture and deliver structure, so your slice holds together after baking.
Step 4: Whisk the Wet Ingredients
In a separate bowl, whisk the eggs with vegetable oil, salt, and pepper until fully combined. This mixture gives your slice essential moisture and helps everything bind into one cohesive dish with a light texture.
Step 5: Combine All Components
Pour the egg mixture over the zucchini and cheese blend. Stir everything thoroughly to integrate the ingredients, making sure every shredded zucchini strand is embraced by the cheesy, eggy goodness. If you want to add bacon bits or ham for an extra savory punch, fold them in here.
Step 6: Add Fresh Parsley
Finally, toss in the chopped parsley to your mixture. This little pop of green is more than just a garnish—it lends a fresh, vibrant flavor that elevates the overall taste.
Step 7: Bake the Mixture
Pour your zucchini mixture evenly into the prepared baking dish, smoothing the top gently. Pop it into your preheated oven and bake for 30 to 35 minutes, until the slice is golden brown on top and firm to the touch. At this point, your slice will smell absolutely irresistible!
Step 8: Cool and Slice
Once baked, remove the slice from the oven and let it cool slightly in the dish for a few minutes. This resting time firms it up, so you can cut neat squares or slices without it falling apart. Warm or at room temperature, this slice is sure to be a hit.
How to Serve Cheesy Baked Zucchini Slice Recipe

Garnishes
Simple garnishes can add an extra layer of appeal. Try sprinkling a bit more grated parmesan or a scattering of fresh parsley on top for color and flavor brightness right before serving.
Side Dishes
This zucchini slice shines alongside fresh salads—think crisp rocket or mixed greens tossed in a light vinaigrette. You could also pair it with a chilled tomato salsa or a dollop of creamy sour cream to add a cool contrast.
Creative Ways to Present
For gatherings, serve the slices on a large wooden board garnished with herbs and cherry tomatoes for a rustic feel. Alternatively, cut into smaller bite-sized pieces and serve with toothpicks at a party, turning this wholesome dish into an irresistible finger food.
Make Ahead and Storage
Storing Leftovers
After enjoying your Cheesy Baked Zucchini Slice Recipe, store any leftovers in an airtight container in the refrigerator. It will keep well for up to 3 days, maintaining its wonderful flavors and texture.
Freezing
This dish also freezes beautifully. Wrap individual slices tightly in plastic wrap and place in a freezer-safe container or bag. Frozen for up to 2 months, you’ll have a convenient, tasty meal ready whenever you need it.
Reheating
To reheat, simply pop the slices in a preheated oven at 160°C (320°F) for about 10-15 minutes or until warmed through. This helps keep the edges crisp while the center stays deliciously soft. Alternatively, a quick microwave blast works for a fast warm-up.
FAQs
Can I use regular flour instead of self-raising flour?
Yes, you absolutely can. If using plain flour, just add about 1 teaspoon of baking powder to help the slice rise and maintain a good texture.
Is this recipe suitable for vegetarians?
Completely! Just skip the optional bacon or ham, and you have a tasty vegetarian-friendly dish packed with veggies and cheese.
Can I make this recipe gluten-free?
Yes, substitute the self-raising flour with a gluten-free baking blend that includes leavening agents. This way, you keep the texture light without gluten.
How do I know when the zucchini slice is fully cooked?
The top should be golden brown and the slice firm to the touch. A toothpick inserted in the center should come out mostly clean, although a few moist crumbs are okay because of the cheese and zucchini.
Can I add other vegetables to this recipe?
Definitely! Finely grated carrot, corn kernels, or chopped spinach can be folded in to add more color, texture, and nutrition without overpowering the cheesy goodness.
