Get this, I had a foods teacher in high school whose whole lesson plan (And decorations in the class) were a time machine back into the 1980s. She taught us how to cook an entire beef roast in the microwave. For what it's worth, this is actually pretty popular in Japan where they've got much more limited kitchen space and often the only cooking appliance available to people is a microwave. It requires a lot more basting and probably a larger amount of electricity compared to what you'd be doing in a conventional oven (especially if you've got a gas oven in terms of energy costs). It's like 40 mins to do though and it turns out... not bad, though I would absolutely prefer a proper convection oven to better results at around the same amount of time.
