One of my favorite gifts for new parents used to be the delivery of homemade meals from Brooklyn-based Susie’s Supper Club. They stopped delivery to Brooklyn and NYC to make their delish dishes accessible to the rest of the country with frozen versions of their kid-friendly best sellers. One of my absolute favorite recipes of theirs, Spinach Squares, and one of their best sellers, will be available frozen and in their new cookbook.
I asked if we could publish Susie’s Spinach Squares recipe here so that we could all make it. Susie agreed, and here it is. I promise you, this is the best way to get spinach into your kids, not hiding it in brownies.
An SSC favorite, these delicious squares are nutrient packed: spinach is a good source of protein, calcium, fiber, iron, niacin, zinc, and vitamins A, C, K, and B6. Nevertheless, kids love these treats! Two cheeses complement the spinach perfectly, so the issue of “eating your vegetables” may never come up.
2 tbsp unsalted butter, melted
3 large eggs
1 cup (8 fl oz/250 ml) whole milk
1 cup (5 oz/155 g) all-purpose flour
1 tsp baking powder
1 tsp kosher salt
1 lb (500 g) Cheddar cheese, shredded
1 lb (500 g) chopped frozen spinach, thawed and drained
1⁄4 cup (1 oz/30 g) grated Parmesan cheese
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.
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.
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.
