Pro Tips

• For the crispiest chaffles, let them rest on a wire rack for a minute after cooking before adding toppings.
• Finely shredded cabbage is a traditional okonomiyaki ingredient and can be used as a substitute for asparagus.
• Don’t overfill your waffle maker, as the egg mixture will expand as it cooks.
• If you can’t find Caciocavallo, a firm, low-moisture mozzarella or provolone makes a great substitute.
