Preheat your oven to 375°F (190°C) and grease a 9x9-inch baking dish.

Slice the zucchini into 1/4-inch rounds, toss with 1/2 teaspoon of salt, and let sit for 20 minutes.

In a large mixing bowl, combine heavy cream, egg, onion, garlic, salt, black pepper, oregano, thyme, and basil. Mix until smooth.

Fold the dried zucchini into the mixture along with half of the panko breadcrumbs and crumbled feta cheese.

Spread the mixture evenly into the baking dish and sprinkle remaining panko breadcrumbs on top.

Bake for about 30 minutes until golden brown and bubbly.
