Prepare the zucchini: Wash them, cut them in half lengthwise, and use a spoon to scoop out the center. Reserve the scooped-out zucchini flesh and chop it finely.4 medium zucchini
Make the filling: In a bowl, mix the chopped zucchini flesh with crumbled feta, cream, and dill. Season lightly with salt and pepper.5.5 oz feta + ½ cup heavy cream + 2 eggs + 4 tablespoons all-purpose flour + ½ teaspoon fine sea salt + ½ teaspoon ground black pepper + 3 tablespoons dill
Stuff the zucchini: Arrange the zucchini halves in a baking dish. Spoon the mixture into the hollowed-out zucchini, then pour any remaining filling evenly over all of them.
Prepare the topping: Melt butter in a small pan, add the breadcrumbs, and stir until they are lightly coated.1 tablespoon butter + 5 tablespoons breadcrumbs
Top and bake: Sprinkle the breadcrumbs over the zucchini and bake in a preheated oven at 350°F/ 180°C for 30-35 minutes, until the zucchini are tender and the topping is golden brown.
Notes
Zucchini: Choose medium-sized zucchini so they fit snugly in the baking dish and cook evenly.
Feta: Use feta from a block of cheese, not pre-crumbled feta.
Make-ahead: You can prepare the zucchini and filling ahead of time, then bake just before serving.
