Ingredients

  • 3/4 cup all-purpose flour
  • 1/4 cup shredded Gruyere or Swiss cheese
  • 2 ounces sliced deli ham, cut into 1/2-inch pieces
  • 2 tablespoons grated Parmesan
  • 1 1/2 teaspoons baking powder
  • 1 1/2 teaspoons sugar
  • Kosher salt and freshly ground black pepper
  • 3/4 cup milk
  • 2 tablespoons unsalted butter, melted, plus more for brushing waffle iron
  • 2 tablespoons vegetable oil
  • 5 large eggs
  • 2 scallions, thinly sliced
  • Special equipment: waffle iron

Method

  • Preheat a waffle iron to medium-high.
  • Preheat the oven to 200 degrees F. Whisk together the flour, Gruyere, ham, Parmesan, baking powder, sugar, 1/4 teaspoon salt and a few grinds of pepper in a large bowl.
  • Whisk together the milk, butter, oil, 1 egg and the scallions in another bowl.
  • Pour the milk mixture into the flour mixture and gently stir until just incorporated (it's okay if there are some lumps).
  • Lightly brush the top and bottom of the waffle iron with butter.
  • Fill the waffle iron about three-quarters of the way full (some waffle iron should still be showing).
  • Close the lid gently and cook until the waffles are golden brown and crisp, 6 to 7 minutes.
  • Keep the cooked waffles warm in the oven or covered with foil on a plate while you make the remaining waffles.
  • Lightly brush the waffle iron bottom with more butter.
  • Crack the remaining 4 eggs right onto the waffle iron and keep the iron open (do this in batches if your iron isn't large enough).
  • Sprinkle the eggs with salt and pepper.
  • Cook until the whites are set and the yolk is still runny, 4 to 5 minutes.
  • Serve 1 egg on each waffle, using a spatula to transfer.
