Preheat the oven to 350°F (175°C) and grease a 9x13-inch baking dish.
Spread the quartered waffles evenly in the bottom of the prepared baking dish.
Layer the shredded chicken over the waffles, followed by the shredded cheddar cheese.
In a large mixing bowl, whisk together the eggs, milk, maple syrup, garlic powder, onion powder, salt, black pepper, and paprika until well combined.
Pour the egg mixture evenly over the chicken and waffles in the baking dish, ensuring everything is well soaked.
Bake in the preheated oven for 30-35 minutes, or until the casserole is set and the top is golden brown.
Let it cool for 5-10 minutes before slicing. Garnish with chopped parsley if desired.
