dredzo is correct! A 20 pound bird will fit the Fryer rated/designed for 20 pounders. Users must be sure they are using the correct model fryer. I have NEVER used an MB fryer (I have a 13 & 20 pound rated fryer ) that did not accommodate the rated size turkey the fryer was designed to fry... I have been frying for years. The answer is in the question... The fryer is not for frozen turkeys!!!
Yes, it will easily fit a 20 lb bird. In fact, bigger birds displace the oil more and cook more evenly. First, a "19 lb bird" that is still frozen probably weighs closer to 16-17 lbs once thawed and the innards (neck, gizzard, liver, heart, etc) are removed. Second, once thawed, the turkey will easily fit into the basket. Just make sure it is very dry inside and out before lowering it into the oil. And lower it slowly: I take about a minute to get the bird all the way into the oil.
Like the other actual users of this product, it fits a big bird, up to a 22# frozen bird. Once cleaned and thawed, ours birds usually weigh in at about 19-20#. It's a tight fit in the basket, but they fit. I put in 3 gallons of oil ( just over the full line of 2.75 gallons), and sloooooosly lower in the basket\turkey. Wear a long sleeve shirt and use oven mitts for safety. The oil just fully covers the bird, and it cooks in about an hour. Been using this model for the last five years, at Thanksgiving and Christmas, in the garage. The garage smells like oil and turkey for about a week, but what a great smell!
I have been using mine for years. It can handle a 2o lb bird, but in my experience, it works best with one that is no more than 15-16 lbs. When I cooked turkeys larger than that they have been a bit dry.
I've cooked three 20 lb. turkeys to absolute perfection in ours. The skin comes out crisp, and if you follow directions, an 85 minute cooking time for a 20 lb bird will give you a 165°F internal temperature with juicy and tender white meat. Just make certain that your turkey is completely thawed and patted dry inside and out. Water/ice will cause splattering.
I have this unit and they do say "up to" a 20 lb Turkey. The reason is that they come in different shapes, to an extent. There may be some 19 lbs that may not fit, however, once defrosted, it probably could be moved and conform better to the drop tray and fit.
