If you’ve got zucchini rolling around in the crisper and a couple of carrots that need using up, this is one of those easy dinners that feels like you actually cooked, even though it’s mostly “grate, stir, bake.” This savory vegetable slice bakes up deeply golden with crisp edges, a tender middle, and plenty of salty Parmesan flavor. It’s great on a busy weeknight, but it’s also the kind of thing I’ll bake on Sunday and quietly rely on for lunches all week.

The only step that really matters is squeezing the zucchini dry. If you skip that, the slice can bake up a little damp in the center. Give it a proper squeeze and you’ll get neat, sturdy rectangles that hold together well and taste even better at room temperature.

Ingredients

2 medium zucchini, coarsely grated (about 4 cups / 360–400 g before squeezing)
2 medium carrots, coarsely grated (about 1 1/2 cups / 150–180 g)
3 large eggs
3/4 cup grated Parmesan (75 g)
3/4 cup all-purpose flour (95 g)
1 teaspoon baking powder
2 tablespoons chopped fresh parsley (about 8 g)
1/2 teaspoon fine salt (plus a pinch to salt the zucchini)
1/4 teaspoon black pepper

Ingredient Notes

Zucchini: After salting, squeeze until it feels noticeably drier and clumps together. This is the difference between a slice that sets up and one that stays a bit wet.
Carrots: Coarsely grated carrots add sweetness and color. If your carrots are very large, use 2 cups (about 200 g) grated and the slice will still bake fine.
Parmesan: Use finely grated for the best melt and even seasoning. Pre-grated works, but freshly grated gives a stronger, cleaner flavor.
Flour + baking powder: These give structure and a light lift. If you want a slightly more tender crumb, you can reduce flour by 2 tablespoons (about 15 g), but don’t go much lower.
Parsley: Adds freshness. You can swap with chopped chives or green onion tops.

Kitchen Tools Needed

Box grater or food processor with grating attachment
Clean kitchen towel or cheesecloth (for squeezing zucchini)
Large mixing bowl
Measuring cups and spoons
9 x 13-inch (23 x 33-cm) baking pan
Parchment paper (recommended) or baking spray
Spatula

Step-by-Step Instructions

Preheat and prep the pan.
Heat the oven to 375°F (190°C). Line a 9 x 13-inch (23 x 33-cm) baking pan with parchment paper (leave a little overhang for easy lifting), or grease it well.
Salt the zucchini.
Put the grated zucchini in a colander or bowl and sprinkle with a pinch of salt. Let it sit for 10 minutes to draw out water.
Squeeze the zucchini very dry.
Wrap the zucchini in a clean kitchen towel (or cheesecloth) and squeeze hard over the sink. Keep going until you’re not getting much liquid and the zucchini feels fairly dry and fluffy. (This step takes a minute, but it’s worth it.)
Mix the batter.
In a large bowl, combine the squeezed zucchini, grated carrots, eggs, Parmesan, flour, baking powder, parsley, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Stir until everything is evenly combined. The mixture should be thick and scoopable, not runny.
Spread in the pan.
Scrape the mixture into the prepared pan and spread it into an even layer about 3/4 inch (2 cm) thick, smoothing the top and pressing it into the corners.
Bake until deeply golden.
Bake for 28–32 minutes, or until the top is deeply golden, the edges look crisp, and the center feels set when lightly pressed. If you want extra color, you can bake another 2–4 minutes, but don’t let it dry out.
Cool briefly, then slice.
Let cool in the pan for 10 minutes before cutting into rectangles. For the cleanest cuts, let it cool a bit longer, then slice with a sharp knife.

Pro Tips

Squeeze the zucchini more than you think you need to. If it still feels wet, keep going—extra moisture is the main reason slices turn out soft in the middle.
Spread evenly. A level layer ensures the center sets by the time the edges are golden.
Use parchment if you can. It makes lifting and slicing much easier (and the bottom browns nicely).
Check the center, not just the color. Ovens vary—press lightly in the middle; it should feel set, not jiggly.
Cool before cutting. A short rest helps it firm up so you get neat rectangles.

Common Mistakes

Not squeezing the zucchini dry enough, leading to a watery, underbaked center.
Cutting too soon, which can make the slice crumble or feel overly soft.
Overbaking to chase browning, which can dry it out—look for set center plus deep gold edges.
Under-seasoning, especially if your Parmesan is mild; taste your Parmesan first and adjust salt slightly if needed.

Variations

Add garlic: Stir in 1–2 cloves minced garlic (or 1/2 teaspoon garlic powder) for a more savory bite.
Make it herbier: Swap parsley for chopped basil, dill, or chives.
Add a little heat: A pinch of red pepper flakes or a few dashes of hot sauce in the batter.
Swap the cheese: Try half Parmesan and half sharp cheddar for a softer, meltier texture (it will be slightly less salty).

Serving Suggestions

Serve warm with a simple green salad and a lemony vinaigrette.
Pair with tomato soup for a cozy meatless dinner.
Top with a fried or poached egg for a more filling plate.
Cut smaller squares and serve as a snack or lunchbox side.

Storage Instructions

Cool completely, then store in an airtight container in the refrigerator for up to 4 days.
For longer storage, freeze individual slices (wrap well or store in a freezer container) for up to 2 months.

Reheating Tips

Oven/toaster oven: Reheat at 350°F (175°C) for about 8–12 minutes to bring back the crisp edges.
Microwave: Works in a pinch (about 30–60 seconds), but the slice will be softer.
If reheating from frozen, thaw overnight in the fridge for best texture, or add a few extra minutes in the oven.

Frequently Asked Questions

Can I make this ahead of time?
Yes. It keeps well and actually slices even more cleanly once cooled. I often bake it earlier in the day and serve it at room temperature or gently warmed.

How do I know the zucchini is “dry enough”?
After squeezing, it shouldn’t drip at all. It should feel light and a bit fluffy, not wet or heavy. If you squeeze and more liquid streams out, keep going.

Can I use gluten-free flour?
A 1:1 gluten-free all-purpose blend usually works well here. The texture may be slightly more delicate, so cool a bit longer before cutting.

Can I use dried parsley instead of fresh?
Yes. Use 2 teaspoons dried parsley in place of 2 tablespoons fresh.

Why did my slice turn out soggy?
Most often it’s excess moisture from the zucchini, or it was cut while still too hot. Squeeze the zucchini very dry and give it at least 10 minutes (more is fine) to cool and firm up.

Conclusion

This is one of those reliable, low-effort bakes that earns a regular spot in the weeknight rotation. Keep the zucchini nice and dry, bake it until deeply golden, and you’ll have a savory vegetable slice that’s just as good for tomorrow’s lunch as it is for tonight’s dinner.
