Ingredients

2 medium zucchinis, grated
Salt, to taste
1 large potato, grated
3 tablespoons (45 g) semolina
50 ml (1/4 cup) milk
1 tablespoon fresh parsley, chopped
1 tablespoon fresh dill, chopped
50-60 grams (1/2 cup) Parmesan cheese, grated
Black pepper, to taste
2 tablespoons (30 ml) olive oil
2 large eggs
70 grams (1/2 cup) all-purpose flour
1 teaspoon baking powder
1 red bell pepper, sliced
2 tablespoons (30 g) Greek yogurt or sour cream

Ingredient Notes

Using fresh zucchini will give the best flavor and texture. If you can only find larger zucchinis, just make sure to scoop out the seeds before grating. Parmesan can be substituted with another hard cheese, but it adds a nice umami flavor that really enhances the dish.

Kitchen Tools Needed

Grater
Large mixing bowl
Casserole dish
Whisk or fork
Baking sheet (optional)

Step-by-Step Instructions

Grate the zucchinis and sprinkle with salt; let them sit for about 10 minutes to draw out moisture.
Squeeze out the excess water from the zucchinis and set aside. Repeat this step for the grated potato.
In a large mixing bowl, combine semolina, milk, parsley, dill, Parmesan cheese, black pepper, olive oil, and eggs; whisk until smooth.
Gradually fold in the flour and baking powder until fully incorporated.
Preheat the oven to 180°C (350°F) and grease a casserole dish with a bit of olive oil.
Layer half of the squeezed zucchini at the bottom of the dish, followed by the potato. Pour half of the batter over the top, then repeat with remaining zucchini and potato, finishing with the rest of the batter.
Arrange the sliced red pepper on top of the casserole.
Bake in the preheated oven for about 20 minutes, or until the top is golden and a toothpick comes out clean.
Meanwhile, prepare the sauce by mixing the Greek yogurt or sour cream with diced cucumbers, chopped olives, and minced garlic in a small bowl.
Serve the casserole warm alongside the yogurt sauce.

Pro Tips

Make sure to squeeze out as much moisture as possible from the zucchini and potato to avoid a soggy casserole.
For added flavor, consider sautéing the zucchini and garlic briefly before adding them to the batter.
This dish reheats well, so making it ahead of time is a great option!

Common Mistakes

Not salting the zucchini early enough can lead to excess moisture.
Forgetting to grease the casserole dish may result in sticking.
Overcooking the casserole can dry it out; keep an eye on it towards the end of baking.

Variations

For a bit of spice, add chopped chili peppers or paprika to the batter.
Swap out zucchini for other veggies like spinach or mushrooms for varied flavors.
You could also add cooked meat, like shredded chicken or ground beef, to the layers for a heartier dish.

Serving Suggestions

This casserole is perfect as a standalone dish but also pairs well with a fresh garden salad or crusty bread. Serve it warm, or at room temperature for a picnic.
