Pour the melted butter into a 9x13 baking pan, rolling it from side to side to make sure all the sides and bottom are covered well with butter.
In a blender, combine the eggs, Greek yogurt, water and salt. Blend for 1 minute on high.
Add in the flour and blend for another minute.
Pour into the baking pan. Bake for 18 minutes. It will puff up differently and unevenly, depending on each oven.
Arrange all the toppings on a BIG BOARD, along with the plates and forks.
Remove the dish from the oven and serve immediately.
Serve the BIG BOARD toppings next to the hot Dutch Baby. Cut into 6 or 8 pieces. We like to add powdered sugar, either jam or maple syrup, and then a squeeze of fresh lemon.
