Electric Roaster Ovens: The Easiest Way to Cook a Big Bird

Capacity is the first decision. Eighteen quarts takes a bird up to about 22 pounds — enough for roughly 17 guests at the standard planning figure. Twenty-two quarts takes 26 pounds, and more usefully, it takes a bird on a rack with a bed of vegetables roasting in the drippings underneath. That second thing is what actually decides 18 versus 22 for most people.

The lid is the second. A dimpled self-basting lid returns condensation to the bird continuously, which means you never open the roaster during the cook. Every time you do open it, the chamber dumps heat it then has to rebuild. If your chosen model lacks one, brine the bird instead and you will not miss it.

The temperature range is the third, and it is underrated. The top end barely matters — you will roast at 325F. The low end decides whether the roaster gets a second job after the turkey comes out, holding your sides at a safe serving temperature while you carve. A model that dials down to 125F is worth paying attention to.

Our sizing guide has the full capacity table, and Oster versus Nesco settles the two most common contenders.

They do not preheat it. Fifteen to twenty minutes with the lid on, before the bird goes in. Starting cold silently adds half an hour to a schedule that has no half hour to spare.

They put water in the bottom. The bird releases plenty of its own liquid, and added water steams it — which makes the pale-skin problem considerably worse. A dry well and a rack is the right setup.

They cook straight in the well with no rack. The underside stews in the drippings rather than roasting, and at the end there is no way to lift a hot 20-pound bird out in one piece.

They keep opening the lid. There is nothing to see, and each look costs real heat. A leave-in thermometer removes the reason to.

The reason a roaster earns its storage space, when a turkey fryer often does not, is that it is genuinely useful the rest of the year. It will hold a large braise or a pork shoulder, cook chili or soup for a crowd, bake a tray of ziti, or keep a buffet of food at a safe serving temperature for an afternoon.

That last use is worth planning for on the day itself. Once the turkey is out and resting, dial the roaster down and use it to hold the sides above 140F while you carve — which is the hardest single problem in hosting, solved by an appliance you already have running. Our guide to keeping food warm covers the full set of options.
