These easy fluffy sheet pan eggs bake into a tender, cheesy breakfast that’s simple to slice and serve. Made with eggs, a splash of milk or half-and-half, cheddar, and fresh herbs, they’re perfect for feeding a crowd or making breakfast sandwiches ahead.
Preheat the oven to 350°F. Spray a 12-by-17-inch rimmed sheet pan with cooking spray, line it with parchment paper, then spray the parchment again to help the eggs release easily.
Crack the eggs into a blender or a large bowl. If using a blender, pulse on the lowest speed just a few times, or whisk gently by hand, until the eggs are combined without becoming frothy.
Add the half-and-half or milk, salt, and pepper. Pulse briefly or whisk until evenly incorporated.
Pour the egg mixture onto the prepared sheet pan. Sprinkle evenly with cheddar, parsley, and chives.
Carefully transfer the pan to the oven, taking care not to slosh the mixture. Bake for 18–20 minutes, until the eggs are no longer jiggly and a toothpick inserted in the center comes out clean.
Let the eggs cool for a couple of minutes, then slice into portions and serve. Add slices to toast, bagels, or English muffins for breakfast sandwiches, if desired.
