Kuku Kadoo (Persian Zucchini Frittata)

Kuku Kadoo (Persian Zucchini Frittata)

کوکو کدو

A delicate, golden frittata showcasing tender grated zucchini bound with eggs and brightened with fresh herbs. Lighter and more subtly flavored than its eggplant or herb cousins, kuku kadoo is prized for its gentle sweetness and silky texture. The key is removing moisture from the zucchini to achieve the characteristic crispy crust while maintaining a tender, vegetable-forward interior. A summer favorite when zucchini is abundant.

Note culturelle

Kuku kadoo is summer cooking at its simplest and best—a way to use abundant zucchini without masking its delicate flavor. It's lighter and more subtle than the robust kuku sabzi or smoky kuku bademjan, making it particularly appealing in hot weather. Persian cooks prize the gentle sweetness of properly cooked zucchini. The dish exemplifies the Persian approach to vegetables: respect the ingredient, enhance it with aromatics, and transform it through technique rather than overwhelming it with seasoning.

Moments Critiques

  • Salting zucchini for at least 30 minutes
  • Squeezing zucchini very dry
  • Pan hot enough to sizzle when mixture added
  • Golden crust developed before flipping
  • Cooking through without burning exterior

Bloom the saffron (if using)

Grind saffron threads with a pinch of sugar using mortar and pestle. Add 2 tbsp hot water and steep for at least 20 minutes.

Grate the zucchini

Trim the ends of the zucchini. Grate on the large holes of a box grater. You should have approximately 800g of grated zucchini (it reduces significantly after salting).

PRÉPARATION35 min

Salt and drain the zucchini

Place grated zucchini in a colander set over a bowl. Sprinkle with 1 tbsp salt and toss to distribute. Let sit for at least 30 minutes, up to 1 hour. The salt draws out significant moisture—you'll see liquid collecting in the bowl.

TextureZucchini becoming limp as water releases

Étape Critique

This is the most important step. Zucchini is extremely water-rich—if not properly drained, the kuku will be soggy and won't develop a crispy crust. The salt also seasons the zucchini from within.

Don't rush this step. The longer you drain, the crispier your kuku will be. You can speed up by placing a plate on top of the zucchini and weighing it down.

Erreurs Courantes

  • Not salting enough
  • Not draining long enough (soggy kuku)
  • Skipping this step entirely

PRÉPARATION8 min

Squeeze the zucchini dry

After draining, take handfuls of zucchini and squeeze firmly to remove as much remaining liquid as possible. Alternatively, wrap in a clean kitchen towel and wring. The zucchini should be as dry as possible—you should extract at least 150ml of liquid total.

OdeurConcentrated zucchini
SonLiquid dripping as you squeeze
TextureZucchini feels relatively dry, not dripping

Étape Critique

Even after draining, zucchini holds water in its fibers. Squeezing removes this remaining moisture. The drier the zucchini, the crispier the crust and the better the texture.

Squeeze in batches, working over the sink. The kitchen towel method is very effective—twist and wring until no more water comes out.

PRÉPARATION3 min

Prepare the onion

Grate the onion on the fine holes of a box grater, or finely dice. If grating, keep both pulp and juice for this recipe—it adds moisture that the flour will absorb.

Chop the fresh herbs (if using)

Finely chop the dill, parsley, and mint. The herbs should be finely chopped but not minced to a paste—you want visible flecks throughout the kuku.

Beat the eggs with seasonings

In a large bowl, beat the eggs with bloomed saffron (if using), turmeric, flour, baking powder (if using), 1 tsp salt, and pepper until smooth and well combined.

Combine all ingredients

Add the squeezed dry zucchini, grated onion, garlic (if using), and chopped herbs to the egg mixture. Fold together gently until evenly combined. If using feta, fold in gently at the end.

Add mixture and cook bottom

Add the zucchini-egg mixture to the hot pan, spreading evenly with a spatula. Press gently to create a compact, even layer. The mixture should sizzle when it hits the pan. Reduce heat to medium-low.

The sizzle confirms proper heat for crust formation. Press gently to eliminate air pockets and ensure even cooking.

Cook until bottom is golden

Cook over medium-low heat for 10-12 minutes without disturbing. The bottom should develop a golden-brown crust and the edges should be setting. Lift an edge with a spatula to check—it should be deep golden, not pale.

Étape Critique

Patience here rewards you with the crispy crust that makes kuku special. Don't flip until the bottom is properly golden.

The kuku should slide freely when you shake the pan. If it's sticking, it needs more time to release.

CUISSON2 min

Flip the kuku

When the bottom is golden and the kuku moves freely, it's time to flip. Place a large flat plate over the skillet. Hold firmly and flip so the kuku lands on the plate, cooked-side up. Add remaining 20ml oil to the pan, swirl, then carefully slide the kuku back in, raw-side down.

Continue cooking over medium-low heat for another 8-10 minutes until the second side is equally golden and the kuku is cooked through. The center should be set, not wet.

Traditional serving

Serve wedges with plain yogurt or mast-o-khiar, lavash bread, and fresh herbs. Kuku kadoo is lighter than other kukus and pairs beautifully with a simple salad for a complete light meal.

Substitutions

zucchiniYellow summer squash works identically. Pattypan squash can be used. Avoid winter squash (wrong texture and moisture content).
fresh herbsDill is most traditional for kuku kadoo. Can use all dill, all parsley, or a mix. Dried herbs are not recommended—fresh is key.
fetaCan substitute Persian feta (lighvan), ricotta salata, or crumbled queso fresco. Omit for dairy-free.
flourChickpea flour (besan) for gluten-free. Rice flour works too.

Mise à l'échelle

Scales easily. Use approximately 150g zucchini and 1 egg per serving. The key is maintaining proper moisture removal regardless of quantity—larger batches may need longer salting time.
