We make meatloaf about once a month or so. We usually use the Cook's Illustrated method (yes, the one with the gelatin, and I beg of you not to yell at me about authenticity) with a few minor modifications (details upon request but I don't think they're too terribly important in terms of this question.) However as with many recipes it makes far too much for our little family to eat in one night, so we usually take the finished mix and form it into two loaves - one to bake for that night's dinner, one to freeze and bake for another night.
So tonight I made one of the frozen ones, as my wife was called away at the last minute. I didn't even have time to defrost it, I just quickly made a pierced-foil-on-a-rack-in-a-rimmed-baking-sheet cooking platform and chucked it in the oven at 350 for 45 minutes. A probe showed it was still incredibly cold in the center so I put it back in for another 35, and then the center showed 150 - good enough.
The thing is... it had an *amazing* crust. Not just some browning like you get on most meatloaves, but a serious deep brown crust that took a bit of cutting to get through. And *yes* that crust was extremely delicious.
So after all that, I guess the question is... could it be possible that freezing a meatloaf could make a better meatloaf by giving it more time to brown on the outside before the insides get cooked?
