Will dry roasting a chuck come out tender?
Roasting is, by definition, &quot;dry.&quot;  Beef chuck can certainly be roasted, and your plan sounds reasonable. It can also be smoked, at an even lower temp.  There are plenty of recipes online.  Whichever your preference, I would measure temperature, rather than rely on time.  I will also add, the texture will certainly be different from a braised chuck, if that is what you are used to.
