Casey Miller, 23, of Constable Walk, Denton, Manchester, pleaded not guilty to robbery when he appeared at Manchester Crown Court.
Five artworks were allegedly taken, together with Lowry's palette and brushes, from the home of Ivan Aird in Cheadle Hulme, Stockport, in May 2007.
Mr Miller was remanded into custody and will go on trial on 16 February.
Among the paintings stolen were The Viaduct, valued at more than £700,000, and The Tanker Entering the Tyne, worth up to £600,000.
LS Lowry, born in 1887, is famous for painting scenes of life in industrial northern England.
