The Best Cheesy Spinach Squares

Cheesy and Delicious, this Spinach Square recipe is a great way to get your kids to eat spinach! Our kid friendly take on the traditional Greek spinach pie (Spanakopita) is incredibly tasty and relatively simple to make. Instead of using phyllo dough, we make the filling of these Spinach Squares a bit more hearty than the traditional version and use mozzarella cheese to create a cheesy and crusty top.

Main Ingredients

This recipe uses super easy ingredients that can be purchased from a local grocery store if they are not already in your kitchen. Read the Recipe Card for the measurements.

  • Spinach – Using frozen spinach is the best way to go, as its more convenient and faster. Make sure to thaw the spinach completely, and then squeeze out all the excess water prior to getting started. You can substitute with fresh spinach, but you would need to cook the spinach and then let it cool completely before using.
  • Cheeses – Our kid friendly version uses mozzarella and parmesan cheese. The mozzarella melts easily and creates that familiar texture from pizza and baked ziti that kids love. The parmesan cheese adds a nutty flavor along with a crusty topping.
  • Onion/Garlic/Spices – Cooking the spinach with fresh onion and garlic and incorporating the rustic spices gives the spinach filling a warm, comforting flavor. You can adjust the heat level from the cayenne pepper to your liking.
  • Flour – We use all purpose flour. You can substitute whole wheat to make it a little healthier.
  • Baking Powder – Helps make the spinach squares rise and become a bit softer and lighter. Make sure to use an aluminum free baking powder.
  • Eggs/Milk/Butter – These baking staples contribute to helping the filling stick together and maintain a moist, creamy texture.
