14 - 1 tbsp butter or additional olive oil
# How to Make It:
01 - Preheat oven to 375°F. Grease a 9x9-inch baking dish with butter or olive oil.
02 - Heat 1 tbsp olive oil in a large skillet over medium heat. Add chopped onion and sauté for 3 minutes until translucent. Add garlic and cook for 1 minute.
03 - Add spinach and cook, stirring, until wilted (about 2 minutes). Remove from heat and let cool slightly.
04 - In a large bowl, whisk together eggs, milk, oregano, black pepper, and salt.
05 - Arrange half of the zucchini slices in the prepared baking dish. Spread half of the spinach mixture over the zucchini, then sprinkle with half the feta and mozzarella.
06 - Repeat the layers with remaining zucchini, spinach, feta, and mozzarella.
07 - Pour the egg mixture evenly over the layered vegetables and cheese. Drizzle with remaining olive oil and sprinkle with red pepper flakes, if using.
08 - Bake uncovered for 35 minutes, or until the casserole is set and the top is golden brown.
09 - Let rest for 10 minutes before slicing and serving.
# Tips for Success:
01 -
- Everything comes together in one pan while the oven does the heavy lifting
- The salty feta balances the mild zucchini in a way that just works every single time
02 -
- Try to slice your zucchini the same thickness so everything cooks evenly
- The casserole needs those 10 minutes of resting time or it will be soupy when you cut it
03 -
- Pat your zucchini slices dry with paper towels if they seem especially watery
- Room temperature ingredients prevent the eggs from scrambling when you pour them over the vegetables
