Beyond Standard Model (BSM) physics addresses puzzles like neutrino mass generation mechanism, dark matter, matter-antimatter asymmetry and the strong CP problem, etc.. Current severe constraints from LHC and dark matter experiments point towards BSM that is either (i) weakly coupled to the SM or (ii) its energy scale is beyond the reach of terrestrial experiments. Faced with this challenge of testing such BSM we try to show that cosmological observables like the inflationary spectral indices, detection of primordial gravitational waves, primordial blackholes and non-Gaussianity provide sometimes an alternate avenue and sometime complementary avenues to test BSM theories. We overview such attempts and in particular we show scenarios involving Higgs-portal dark matter, baryogengesis via leptogenesis and axion physics in early universe that may lead to testable predictions for such observables to complement the laboratory observables.
