A one-pound ground beef meat loaf cooks in the microwave oven in about 10 minutes on HIGH. The same loaf in the conventional oven would take 45 minutes to an hour at 350 degrees.
A loaf made of a pound of ground beef will make twice the amount needed for most couples, but many meat loaves, especially Mexican-Style Meat Loaf Wedges, are excellent to slice and serve cold. An innovative cook tells me she uses leftover meat loaf in her stuffed baked potatoes. Meat loaves offer unlimited variations, and with the microwave oven they are almost a convenience food.
For even cooking in most ovens, the meat loaf mixture should be spread in a thick patty in a glass pie plate. If you prefer to use a glass loaf dish, start the loaf cooking on HIGH for three to four minutes, then finish on a lower setting of 70% power for 10 or 12 minutes, or on 50% power for about 15 minutes. This will give an even heat distribution in the thicker mass of meat.
