Literally, "chuck roast" translated to Spanish is "chuck asado".
However... I would be wary of taking this at face value, some terms do not really have a like-for-like translation.
A chuck roast is a colloquial term that originates from the US. There are english speakers in other countries who would need a translation as to what it is, let alone people who speak different languages!
Chuck is a cut of meat, and not a term that is used in Spanish, and asado technically refers to barbecuing, or the social event of having a BBQ.
Rather than looking for a translation of the words, it might make better sense to look for a similar sort of dish in Spanish cooking: Carnes al horno is a dish where beef is slow roasted in the oven, so that is probably a more accurate translation of what you are looking for.
