Ingredients You’ll Need

A white marbled surface holds several ingredients neatly arranged, including a small white bowl with a yellow mustard dollop at the top left, below it a white bowl with a bright yellow liquid likely oil, and near the center a grey plate with a solid block of butter. A block of blue-lidded cottage cheese is next to a fresh dark green zucchini, which lies next to a leafy pile of fresh spinach stacked in a white bowl. Above this, a small white bowl contains frozen green peas, next to which is a whole light brown onion and a garlic clove. At the top center is a black bowl filled with five brown eggs, and a small white bowl with salt sits above the butter. A fresh dense broccoli head with a bright green color rests in the middle of the layout. Finally, a white bowl filled with white flour is placed on the right side, all arranged on the white marbled background. Photo taken with an iphone --ar 4:5 --v 7

How to Make Healthy Zucchini Slice Recipe

Step 1: Prepare Your Oven and Pan

Start by preheating your oven to 180 degrees Celsius (355 degrees Fahrenheit). Grab a slice pan roughly 19 cm by 29 cm and give it a good grease and lining with baking paper. This sizing helps the slice bake evenly and not get too thick or thin, ensuring perfect cooking from edge to center.

Step 2: Cook the Onion

In a frying pan over medium-high heat, warm 1.5 tablespoons of olive oil, then add the finely chopped onion. Stir it often for about 5 to 6 minutes until the onions become soft and translucent, releasing their natural sweetness. Set this aside to cool slightly while you prep the rest of your ingredients.

Step 3: Prep the Vegetables

Grate the zucchini and then, using your hands, squeeze out some of the moisture over the sink. This step is a lifesaver to avoid a soggy slice. Next, chop the broccoli florets and roughly chop the baby spinach leaves along with the garlic clove. Your fresh veggie medley is now ready to mix in.

Step 4: Whisk the Batter Base

In a large bowl, whisk together the eggs, salt, pepper, and Dijon mustard until consistency is smooth and slightly thickened. Gradually add in the self-raising flour, whisking carefully so there are no lumps. This batter is the backbone that will keep all the goodies suspended wonderfully.

Step 5: Combine All Components

To the batter, add the cottage cheese, grated Cheddar, cooked onion, garlic, grated zucchini, broccoli, peas, and spinach. Pour in the extra 2 tablespoons of olive oil, then gently fold everything together until the mixture is well combined. You’ll see an inviting texture with bursts of green and gold throughout.

Step 6: Bake to Perfection

Pour the mixture into your prepared pan and smooth the top with a spatula. Slip it into the oven and bake for about 35 minutes until the slice turns a gorgeous golden brown and is cooked through. For those who love a bit of crunch on top, a quick few minutes under the grill at the end will do the trick beautifully.

Step 7: Cool and Slice

Let your zucchini slice cool for a little while before transferring it onto a clean board. This resting period helps the slice firm up slightly, making it easier to cut into neat pieces without crumbling. Serve warm or at room temperature for maximum enjoyment.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Freezing

This Healthy Zucchini Slice Recipe freezes beautifully. Wrap individual slices tightly in cling film, then place them in a freezer bag. They’ll keep well for up to 2 months, so you can enjoy homemade goodness anytime.

Reheating

To reheat, simply warm the slice in a preheated oven at 160 degrees Celsius (320 degrees Fahrenheit) for about 10-15 minutes or until heated through. Avoid microwaving if possible to preserve the lovely texture.

FAQs
