I baked it for 20 mins. at 325, then pulled it out to sprinkle more cheese on top and baked it another 10 mins. There was a perfect amount of bacon, because half the recipe (what I brought home) fit perfectly in an 8x8 dish and the bacon just covered the top. (I had to dig the bacon out of the mess--with clean hands, of course!) Here is a picture of it after I got our three servings out.
I was convinced that the amount I put in our bowls wouldn't even come close to filling us up, but it was actually the perfect amount. The potatoes were filling, and the cheese sauce was good, and then of course we each had three pieces of bacon!
