An electric grill for cooking hamburgers and other foodstuffs includes a first grill plate assembly adapted for use atop a kitchen countertop, table top, or other horizontal support surface, a second grill plate assembly connected by a hinge arrangement to the first grill plate assembly in a clamshell arrangement, and a bun warmer portion of the second grill plate assembly that defines a compartment adapted to hold at least one bun (e.g., a hamburger bun) in order to warm the bun. In one embodiment, the bun warmer portion of the second grill plate assembly includes a metal plate adapted to support the bun, and a vented transparent lid over the plate. The first grill plate assembly may include an electric grill plate with an inclined cooking surface that slopes to facilitate grease runoff to a drip tray, and components in the form of leg extensions for adjusting the height of the first cooking surface above the horizontal support surface.
