When you have to make bacon by the case, it's impractical to cook it on a grill or stove top. We bake it all the time. Preheat the oven, it's important to have a hot oven, just like you'd have a hot pan. You could even heat the baking sheet in the oven, as well...
At work, the bacon comes in sheets, layed out on parchment. We bake it right on the parchment, on the pan. The parchment helps absorb some of the grease. You can or cannot do this step, it's up to you. Lay the slices out, side by side. Don't be afraid to overlap them, remember, they'll shrink. You don't have to flip them as you would in a frying pan, either. My convection oven usually finishes them in about 10 minutes. How you like it will determine the time. Check after 8 minutes.
