Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with cooking spray.

Stir in the shredded cheddar cheese, shredded mozzarella cheese, and grated Parmesan cheese, reserving a little of each for topping.

Fold the cooked spinach mixture into the egg and cheese mixture until evenly distributed.

Step 7

Pour the mixture into the prepared baking dish and spread it out evenly. Sprinkle the reserved cheeses on top.

Remove from the oven and let it rest for 5-10 minutes before slicing and serving.
