Prepare the Spinach:

• Preheat a large sauté pan over medium heat. Add spinach and cook until wilted. Drain excess water and set aside.

Make the Filling:

Preheat the Oven:

• Preheat your oven to 350°F (175°C).

Assemble:

• Brush a 9×13-inch baking dish with olive oil.
• Place a sheet of phyllo at the bottom of the dish, brush with olive oil. Repeat this step, layering and brushing each sheet, until you have 8 sheets layered.
• Spread the spinach-feta mixture evenly over the phyllo.
• Continue the layering process with the remaining 8 sheets of phyllo, brushing each with olive oil.

Bake:

• Place the baking dish in the preheated oven and bake for 40-45 minutes, or until the phyllo is golden brown and crispy.
