1. Adjust a rack to the lower-middle position and heat oven to 450 degrees. Grease two 6-cup popover pans with butter.
2. Whisk flour, milk, eggs, and salt together until just combined (batter will be lumpy). Fill each pan two-thirds full and bake 20 minutes.
3. Reduce oven to 350 degrees and continue baking until popovers are golden brown all over, 20 minutes.
4. Transfer to a wire rack, pierce tops with the tip of a knife to release steam, and let cool slightly before serving.
