In a large bowl, whisk the eggs and milk. Add the flour, salt, and sugar and whisk to combine. Break up any large clumps of flour. A few small lumps are okay.
Place the butter in either a 9-inch pie dish or a 9x9 metal square baking dish. Place the dish in the oven and allow the butter to melt and start to brown, about 3-5 minutes. If you’re using a metal baking dish, the butter will brown faster than if you’re using a ceramic dish. Do not allow the butter to burn. Remove the dish from the oven.
Pour the batter into the dish with the melted butter as soon as you remove it from the oven. Place it back in the oven and bake for 12-15 minutes or until the sides have risen significantly and the edges are golden brown.
Notes
Dish Recommendation: If you’re looking for an alternative to using a cast-iron skillet to make a Dutch Baby Pancake, based on the testing above, I would recommend using a 9x9 square metal dish or 9-inch round pie dish.Browning Butter: If using a metal baking dish, the butter will brown faster than if using a ceramic baking dish. Bake the butter for 3-4 minutes for a metal dish and 4-5 minutes for a ceramic dish or until lightly browned.
