Melt 2 tablespoons of butter in a skillet over medium heat. Add the onion and celery; season with a generous pinch kosher salt and black pepper. Sauté until tender, about 5 minutes. Transfer to a large mixing bowl.
Add the bread cubes, eggs, herbs, salt, and season with black pepper. Pour in 3/4 cup of the broth and toss to combine. Add more broth if needed to make sure all the bread gets moistened. Let it sit for 10 minutes.
Preheat a waffle iron. Melt the remaining butter to grease the waffle iron. Use about 1/3 cup of stuffing mixture per waffle. Cook until crispy and golden (cook time will vary based on waffle maker; mine took about 5 minutes).
Set aside on a baking sheet as they're done. You can warm them up in a 300°F oven until hot. Serve warm.
Notes
Number of servings – this may vary based on how much filling you use per waffle; I used 1/3 cup of filling.
Cook time – each batch of waffles were cooked to my liking in about 5 minutes on my waffle maker, which makes 2 waffles at a time. The cook time will vary based on the appliance and how many waffles you can make at a time.
