The BREAD Collaboration proposes an ambitious program of broadband searches for terahertz axion dark matter. Its experimental hallmark is a cylindrical metal barrel converting axions to photons that are focused by a parabolic reflector to an ultralow noise photosensor. Practically, this novel dish antenna geometry enables enclosure inside standard cryostats and high-field magnets. We present an overview of the BREAD conceptual design and science program from dark photon pilot planned at Fermilab to large-scale experiment. BREAD is projected to open multiple decades of unexplored coupling sensitivity across the meV to eV mass range that has long eluded existing resonant-cavity haloscopes. Based on Phys. Rev. Lett. 128 (2022) 131801
