Ingredients

• Unsalted butter or nonstick vegetable oil spray
• 18 large eggs
• 1/3 cup milk
• 2 teaspoons kosher salt
• 1/4 teaspoon freshly ground black pepper

Instructions

1. Preheat oven to 350°F. Grease an 18x13" rimmed baking sheet with butter or spray. Blend eggs, milk, salt, and pepper in a blender until well combined.
2. Place prepared baking sheet on oven rack and carefully pour in egg mixture. Bake until just set in the middle, 12–14 minutes.
3. Let cool slightly, then cut into 18–20 squares.
4. Eggs can be made 3 days ahead. Slice, transfer to an airtight container, and chill. Warm slightly in a toaster oven or microwave before serving, if desired.
