Let’s talk about the buns. I used gluten-free hamburger buns for this recipe but brioche buns, potato rolls, or even Ciabatta Rolls can turn out delicious.
The first thing to do is butter the inside parts of the buns. Melt that butter and brush it in. Then, after a pan is heated up, place on those buns butter side down until they get crispy. This usually takes 5-7 minutes.
OK, time for those smashed burgers to turn golden brown. If you have a cast-iron skillet, that would be the preferable option. Cast iron skillets are able to retain heat at higher temperatures and lock in flavors that circle around the pan. If you end up buying one, make sure it is pre-seasoned.
Heat the skillet with oil and, once hot, gently place the burgers in the pan. Season with salt, pepper and if you have a burger seasoning that is a plus. Leave grilling for 3 minutes and then flip over. As soon as they are flipped to the other side, grab your cheese and gently blanket the burgers. Turn off the heat and leave in the pan for another 3 minutes.
