Step 1

Preheat oven to 300 degrees F. Generously coat a large rimmed baking sheet with cooking spray.

Step 2

Whisk eggs, milk, smoked paprika, salt, pepper and onion powder together in a large bowl. Pour onto the prepared baking sheet and sprinkle with spinach, Cheddar and ham. Bake until just set, 20 to 25 minutes, rotating the pan from back to front halfway through baking to ensure even cooking. Cut into 12 squares and serve.
