We combined photometry from the All Sky Automated Survey (ASAS) and the Transiting Exoplanet Survey Satellite (TESS) with high-resolution spectroscopy from the ESO public archive to obtain, for the first time, absolute physical and orbital parameters for six double-lined detached eclipsing binary systems with solar-type components. The atmospheric parameters of the stars have been determined from the individual spectra obtained from a disentangling method. One of the targets resulted in a triple system, and lines coming from three components in spectra show that each component's contribution to the total light is approximately equal. For the six systems the masses and radii of the components were obtained with a precision better than 3%. A comparison of the observed stellar parameters with the prediction of stellar evolution based on the MESA stellar evolution code shows reasonable agreement.
