In Amsterdam he worked as a painter of genre works, and portraits. He won a very good following as a painter, winning a lucrative commission for a large commemorative piece for the state visit by Maria of Medici in 1638, which hangs in the Rijksmuseum. This piece was commissioned by the Bicker Company of the Amsterdam schutterij, and shows the members posing around a bust of Maria of Medici, with a poem by Joost van den Vondel hanging below it. The state visit was a big deal for Amsterdam, as it meant the first formal recognition of the Dutch Republic of the seven provinces by France. However, Maria herself was fleeing Richelieu at the time and never returned to France. This piece cemented his reputation as a leading painter, and in 1645 Sandrart decided to cash in and go home when he received an inheritance in Stockau, outside Ingolstadt, he sold his things and moved there. He received 3000 guilders for 2 books of his Italian drawings, that according to Houbraken were resold in his lifetime for 4555 guilders. Though he rebuilt the old homestead, it was burned by the French. He sold it and moved to Augsburg, where he painted for the family of Maximilian I, the Elector of Bavaria. When his wife died in 1672, Sandrart moved to Nuremberg, where he married Hester Barbara Bloemaart, the daughter of a magistrate there. This is where he started writing. His large 1649 painting Peace-Banquet commemorating the Peace of Münster, now hangs in Nuremberg's town hall.

This work is an educational compilation of short biographies of artists, as "a printed supplement to or surrogate for an academic course," inspired by Karel van Mander's similar Schilder-boeck. Both Sandrart and van Mander based their Italian sections on the work of Giorgio Vasari. His work in turn became one of the primary sources for Arnold Houbraken's Schouburg, who wrote a little poem about him: Sandrart copied a mistake in Cornelis de Bie's Het Gulden Cabinet on Hendrick ter Brugghen whom De Bie has erroneously called "Verbrugghen". De Bie corrects this mistake in a manuscript and attacks Sandrart for having copied the
