A gas-fired or briquette-burning barbecue grill that outputs extremely high BTUs from a removable, vertical firebox that is backwardly inclined so as to provide a combination of direct and indirect heating. In addition, multiple cooking grids positioned at various vertical levels across the face of the firebox provide an enormous cooking area for grilling, broiling, and searing. Inclination minimizes ash avalanche during briquette burning and also increases the effective heating area applied to multiple cooking grids of gas-fired and briquette-burning grills. A top grid located directly over the firebox provides a surface for searing or high-temperature cooking (i.e., direct heating), a mid-level cooking grid provides medium temperature indirect and/or partial direct heating cooking, and a lower main cooking grid provides indirect medium temperature for broiling or baking. A pair of opposed insulated sidewalls on each side of a central heating area includes respective sets of rail guides which support cooking grids at varying distances from the firebox. The sidewalls also help confine heat in and about the cooking grids and may also support a removable, hinged cover lid that establishes an oven-like enclosure about the mid-level and main cooking grids to provide a baking/broiling chamber. Grid elements of the main cooking grid, which is downwardly inclined about three degrees toward the front of the gill, comprise oppositely facing channels that route grease drippings from cooking foodstuffs to a grease-catching receptacle. The firebox rests in a cradle or receptacle and is adapted to be easily removed by a grasp handle insertable in a surface of the firebox. A wire basket inside the metal firebox retains briquettes in spaced relation to the firebox walls thereby to provide an ash reservoir for briquettes as they burn and/or to thermally insulate hot fuels from the sidewalls and top lid of the grill. Portable versions of the grill collapse like a suitcase (with all grill components contained therein), fold-up legs may be provided, side shelves may be attachable, and/or a rotisserie rod may be added.
