# Directions:
01 - Preheat oven to 375°F. Grease a 9x9-inch baking dish with butter or olive oil.

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, until the casserole is set and the top is golden brown.
09 - Let rest for 10 minutes before slicing and serving.
# Expert Tips:
01 -
- The way the feta gets all golden and slightly crispy on top while staying creamy underneath is absolute magic
- Its one of those rare dishes that tastes even better the next day, so lunch is already sorted
02 -
- I learned the hard way that cutting into this immediately makes a beautiful mess, so the resting time is not optional
- Extra zucchini release a lot of water, so if your slices are thick, consider sprinkling them with salt and letting them drain for 15 minutes before assembling
03 -
- Pat the spinach dry after wilting to prevent the casserole from becoming watery
- Let the finished casserole sit for at least 10 minutes before serving so it sets properly
