Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C). Lightly grease a baking dish with butter or oil and set aside.
- Wash the zucchinis and slice them into 1/4-inch thick rounds.
- Toss the slices with a pinch of salt and let sit for 10 minutes to draw out excess moisture.
- Pat dry with paper towels to prevent sogginess.
- While the zucchinis rest, grate the cheddar and mozzarella cheese.
- Prepare the breadcrumbs by toasting them in a pan with a tablespoon of melted butter until golden and fragrant, then set aside.
- In a mixing bowl, whisk together the sour cream, beaten eggs, lemon juice, chopped herbs, and a pinch of salt and pepper. This will be your creamy filling layer.
- Layer the zucchini slices evenly in the prepared baking dish.
- Spread a portion of the cheese mixture over the zucchini, then repeat the layers until all ingredients are used, finishing with a generous sprinkle of cheese on top.
- Pour the remaining sour cream mixture evenly over the layered zucchini, ensuring it seeps into all corners. Sprinkle the toasted breadcrumbs and some extra cheese over the top for a crispy crust.
- Bake in the oven uncovered for 35-40 minutes, until the top is golden brown and bubbling. The edges should be crisp, and the cheese melted and gooey.
- Remove from the oven and let rest for 5-10 minutes. This helps the casserole set and makes slicing easier.
- Slice and serve warm, garnished with extra herbs if desired. Enjoy the crispy topping with tender, cheesy zucchini layers.
