Cheesy Spinach Squares

By Caitie

Ingredients

• 2 tbsp unsalted butter, melted
• 3 large eggs
• 1 cup whole milk
• 1 cup all-purpose flour
• 1 tsp baking powder
• 1 tsp kosher salt
• 1 lb Cheddar cheese, shredded
• 1 lb chopped frozen spinach, thawed and drained
• 1/4 cup grated Parmesan cheese

Preparation

Step 1

1. Preheat the oven to 375°F (190°C). Line a 9-by-13-inch (23-by-33-cm) rimmed baking sheet or baking dish with parchment paper. Pour the melted butter into the prepared pan and spread to coat evenly.

2. In a large bowl, beat the eggs until well blended. Whisk in the milk, flour, baking powder, and salt. Add the Cheddar and spinach and stir until combined. Pour the spinach mixture into the prepared pan and spread in an even layer. Sprinkle the Parmesan evenly over the top.

3. Bake until the top is lightly browned and the juices are bubbling, 30–40 minutes. Transfer to a wire rack and let cool until just warm to the touch. Cut into 2-inch (5-cm) squares and serve.
