Somewhere between a soufflé, a crust-less quiche, Spanish tortilla and a frittata, a sfougáto is an egg dish baked in the oven. It's especially popular on the Aegean islands, each of which has its own tweak, although most include zucchini (courgettes) and onions:
On Lésvos, they make it with potato, parsley, spring onions, feta and plenty of fresh dill and mint.
On Rhodes, they add ground beef, feta, a little zucchini, thyme and oregano.
On Crete, they leave out the cheese and meat but add a tomato (some used slice fried potatoes instead).
On Santoríni they use a lot of zucchini, mint, xinomyzithra and graviera paprika and toasted sesame seeds.
On Chíos they leave out the zucchini, but use onion, cheese, mint and breadcrumbs.
There's a Piraeus version, too, with ground lamb, zucchini, onion, dill, parsley but no cheese.
