Preheat an oven to 425°F. Pour 1/2 tsp. of the melted butter into each 6-cup popover pan. Put in the oven for 4 minutes to heat the pan.
In a bowl, whisk together the eggs and milk, then whisk in 2 Tbs. of the melted butter.
In a large bowl, whisk together the flour and salt, then whisk in the egg mixture. Whisk vigorously until smooth, about 2 minutes. Add the shredded Parrano cheese and Italian seasoning and mix to combine. Divide the batter among the prepared cups and bake for 30-35 minutes until a rich brown. DON’T PEEK while baking. Remove from the oven and invert the pan onto a wire rack.
