Mini Burgers with Cheesy Onions
Burger sliders get even better when they're inspired by a cheeseburger recipe. Layer caramelized, cheesy onions between the mini burger buns (alongside the juicy beef patties, of course) for a tasty handheld treat.
The internal color of a burger is not a reliable doneness indicator. A beef patty cooked to 160°F is safe, regardless of color. To measure the doneness of a patty, insert an instant-read thermometer through the side of the patty into the center.
