In a separate bowl, whisk the milk, egg, and melted butter until smooth.
360 ml Milk, 1 Large egg, 60 Grams butter
Gradually pour the wet ingredients into the dry ingredients, stirring gently until just combined. The batter should be slightly lumpy, do not overmix.
Gently fold in the grated cheese, diced ham, and chopped green onions until evenly distributed throughout the batter.
Spoon the batter into the preheated waffle iron, filling it according to your waffle maker's capacity. Close the lid and cook for 3-5 minutes, or until the waffles are golden brown and crisp.
Carefully remove the waffles and serve immediately with your favorite savory toppings.
Notes
Tips and Tricks
Don't overmix: Overmixing the batter can make the waffles dense instead of light and fluffy.
Cheese swaps: Try mozzarella, Gruyère, or Swiss cheese for a different flavor.
Crispier waffles: Let the waffles cook until deeply golden for extra crisp edges.
Make ahead: Keep cooked waffles warm in a low oven (100°C / 210°F) while finishing the batch.
Serving ideas: Top with a fried egg, sour cream, avocado, or a drizzle of hot sauce for extra flavor.
