Zucchini Slice with Smoked Turkey

This dish is an Australian classic. It is the kind of thing you find at every community bake sale or school picnic, usually served at room temperature. It's essentially a savory cake that lets you sneak a lot of vegetables into a meal without anyone complaining.

The combination of sharp cheddar and smoked turkey gives it a punchy flavor. Because it's dense and filling, a few squares can easily handle a full lunch.

This zucchini slice is straightforward to put together. As long as you handle the moisture in the vegetables correctly, it comes out firm and sliceable.

Savory Zucchini Slice Recipe

Moisture Control: Squeezing the zucchini removes the water that usually makes these cakes mushy. Egg Structure: Five eggs provide the lift and bind needed to keep the squares from falling apart.

You can choose between the oven or an air fryer depending on how many people you're feeding. The oven is the standard way to get that dark golden top across the whole pan.

Ingredients and Smart Swaps

A Closer Look at the Ingredients

This recipe is designed to be economical. Smoked turkey delivers a rich, cured taste without the cost of gourmet meats.

• 3 cups (300g) zucchini, grated Why this? Adds bulk and a fresh quality
• 1 medium (110g) brown onion, finely diced Why this? Creates a base of savory sweetness
• 1/2 cup (60g) smoked turkey, finely chopped Why this? Provides a rich, salty punch
• 1 cup (120g) sharp cheddar cheese, grated Why this? The tang balances the eggs
• 5 large eggs Why this? Necessary for the custard to set
• 1 cup (125g) self-raising flour Why this? Keeps the texture light
• 1/2 cup (120ml) olive oil Why this? Ensures a moist crumb
• 1 tsp (6g) salt Why this? Brings out the other tastes
• 1/2 tsp (1g) ground white pepper Why this? Adds mild heat without the dark spots

I suggest white pepper for a cleaner visual appearance, though black pepper is a perfectly acceptable alternative if you don't mind the flecks.

Gear for the Job

You only need a few basics. A coarse grater is a must for the zucchini, and a clean kitchen towel is essential for the squeezing phase. Use a 9x13 inch baking pan and parchment paper to ensure the slice lifts out without sticking.

From Prep to Plate

Phase 1: Drying the Zucchini

1. Use the coarse side of a grater to shred the 300g of zucchini.
2. Transfer the shredded zucchini to a clean kitchen towel and press firmly over the sink to drain as much liquid as possible. Note: This prevents a soggy center

Phase 2: Preparing the Batter

3. Heat the oven to 350°F (180°C) and line a 9x13 inch (23x33 cm) baking pan with parchment paper.
4. In a large mixing bowl, whisk 5 eggs and 120ml olive oil until the mixture is smooth.
5. Mix in 6g salt and 1g white pepper.
6. Fold in the dried zucchini, 110g diced onion, 60g chopped smoked turkey, and 60g (half) of the grated cheddar cheese.

   

7. Sift in 125g self-raising flour and stir gently until just combined. Note: Do not overmix or it will get tough

Phase 3: Baking and Serving

8. Transfer the batter to the prepared pan and level the top with a spatula.
9. Evenly distribute the remaining 60g of grated cheese across the surface.
10. Bake for 35–40 minutes until the top is dark golden, the edges slightly pull away from the sides, and the internal temperature reaches 160°F (71°C).

    

11. Let the bake cool in the pan for 10 minutes, then lift it out using the parchment paper and slice into 8 squares.

Common Problems and Fixes

Soggy Center Fix

This happens when the zucchini isn't squeezed enough. Zucchini is mostly water, and if that stays in the batter, it steams the cake from the inside. Use a towel and really put some weight into it.

Sinking Middle Issues

If the center dips, it's often due to overmixing the flour or pulling it out too early. Once the flour goes in, stir just until the streaks disappear. Check the internal temperature with a thermometer to be sure it's set.

Pan Sticking Fixes

If the squares tear when you lift them, the parchment might be too small or missing. Always overlap the edges of the pan with the paper. If you don't have paper, grease the pan heavily with oil and a dusting of flour.

Easy Swaps and Add-Ins

For a vegetarian zucchini slice with feta, swap the turkey for 1/2 cup of crumbled feta. This adds a tangy, salty kick that pairs well with the onion. I like adding a handful of baby spinach to the batter for extra color.

If you want a quicker stove-top version, try this Skillet Zucchini Squash instead. For a richer, creamier bake, a Zucchini Squash Casserole is a great alternative.

You can also make a high protein zucchini slice by adding a 1/4 cup of almond meal or mixing in some cooked quinoa. Just be aware that the texture will be slightly denser.

Keeping the Slice Fresh

Once this zucchini slice has cooled completely, keep it in a sealed box in the refrigerator for up to 4 days. It's actually a bit better the next day once the flavors have settled.

You can freeze individual squares. Wrap them in parchment and put them in a freezer bag for up to 3 months. Thaw them in the fridge overnight. To reheat, use a dry pan over medium heat for 2 minutes per side, or microwave for 60 seconds, until the centre reaches 165°F (74°C).

Best Side Pairings

A simple rocket (arugula) salad with lemon vinaigrette provides a zesty contrast to the rich cheese. For brunch, try adding a few sliced cherry tomatoes and a spoonful of Greek yogurt or sour cream on top.

The Texture Mechanics

The success of this zucchini slice depends on the balance of fats and proteins. The olive oil and melted cheese create a rich environment that prevents the flour from making the dish feel like a dry loaf of bread.

The eggs act as a structural net. As they heat up, the proteins coagulate and trap the vegetables in a firm custard, which is why it holds its shape so well when sliced.
