Example embodiments provide lighting fixture mounting kits for mounting a flat panel lighting fixture to a mounting surface. The lighting fixture mounting kits may comprise a mounting portion (e.g., a mounting plate) and a lighting fixture. The mounting portion may be secured relative to a mounting surface and may comprise mounting catches. The lighting fixture may be secured relative to the mounting portion, and may comprise fixture catches configured to selectably engage the mounting catches. The lighting fixture may be slidable relative to the mounting portion between an engaged configuration in which the fixture catches are engaged with the mounting catches; and a disengaged configuration in which the fixture catches are disengaged from the mounting catches. When in the disengaged configuration, the lighting fixture is pivotable away from the mounting portion to facilitate access to a back portion of the lighting fixture.
