There is no one right answer to this question, as the best way to cook burgers indoors will vary depending on your preferences and what type of burger you are cooking. Some tips to follow when cooking burgers indoors include heating a large skillet or griddle over medium-high heat, adding a little oil or butter, and adding the burgers to the pan. You can also cook the burgers in a bun, if you prefer. Just be sure to heat the buns before adding the burgers to the skillet or griddle, to ensure they are warm and toasty.
