Persian Zucchini Frittata
This zucchini frittata is like a vegetable quiche with no crust. So delicate with crispy golden edges. It is a gorgeous frittata with a rich flavor from the addition of spices, which also give an anti-inflammatory boost to the dish.
Persian frittata or kuku is easy, quick to prepare and works well for any meal of the day. It can be a main dish with salad or bread. Or serve it as a side dish. It combines the high quality egg protein with lots of veggies.
Apart from saffron and Persian spice blend (advieh), kuku has turmeric. Curcumin, the active substance in turmeric has been found to have health benefits for heart health, cancer prevention, brain health, inflammatory bowl diseases, diabetes and more.
How to Make it
- Sautรฉ thinly sliced zucchini with onions and garlic until softened. Squeeze juices really well.
- Combine salt, spices, flour and baking powder. Add a third of whisked eggs into the spice-flour mixture and mix well. Pour remaining whisked eggs and stir.
- Then combine sautรฉed vegetables with eggs. Adjust the seasoning.
- Heat oil in a skillet, pour egg-vegetable mixture and bake it uncovered for 20 minutes.
- Spread ยฝ to 1 tablespoon butter or olive oil and sprinkle chopped herbs.
- Bake for another 5-10 minutes until golden brown on the top.
- Loosen baked zucchini omelette from the pan and cut into wedges.
Pro Tips and Tricks
- Much of the antioxidant potential of zucchini is in the skin. So, donโt peel it away. Use organic zucchini and scrub it nicely with a vegetable brush.
- Slice the zucchini very thin or you may grate it thick. Cook them until soft and tender.
- While cooking the zucchini, some juices are released. Be sure to squeeze the juices really well before adding to the whisked eggs. (You can add the drained juices to another soup or stew.)
- You could add some parmesan, feta or goat cheese if you prefer. Up to ยฝ cup would be ok for this recipe - โ rd added into the mixture and the rest on the top.
- For a creamy frittata you may add 2 tablespoon heavy cream, half-and-half, whole milk, sour cream, yogurt or crรจme fraรฎche. Adding cheese or creamy additions to kuku is not typical in Persian cuisine.
- Persian spice blend (advieh) can be substituted with a โmildโ middle-eastern or eastern Mediterranean spice blend.
- Bake the frittata at a low temperature. Higher temperature may result in a kuku (frittata) that is dry and with an off flavor.
- Don't overcook the frittata. It needs to be puffed, but tender in the center. Remember that the cast iron skillet will continue to impart some heat to the frittata.
- Traditional Persian zucchini frittata (kuku kadoo) recipes use a pat of butter on the top, but olive oil works well too.
Storage and Leftovers: This Zucchini frittata keeps well in the refrigerator for a few days. Warm it up in the oven or in a skillet.
Freezer Friendly: It does freeze well up to two months. In fact, I make some batches and freeze them for a quick meal or dish after travel. Just thaw and reheat loosely covered in an oven or in a skillet.
Make Ahead: You can sautรฉ the zucchini and drain them. Whisk the eggs with all the other ingredients except the baking powder, which should be added just prior to cooking.
Is Zucchini Healthy?
So now a little bit more on the star of the show โ Zucchini! It is a member of the cucurbitaceae family along with pumpkins, cucumbers and gourds.
Zucchini is low in calories and carbohydrates. And high in free radical fighting nutrients such as vitamin C and manganese. This vegetable is also rich in B vitamins, that participate in energy metabolism.
Then it is good for eye health as it is a good source of the carotenoids โ lutein and zeaxanthin. It is rich in potassium, the nutrient that balances sodium levels and regulates blood pressure โ which makes it very heart healthy. And is a good source of dietary fiber.
Zucchini has a high percentage of water, so it makes a filling and satisfying dish. That is so good for maintaining a healthy body weight with a nutrient dense food. And it is easy to digest too.
